You are a Master Refrigeration Repairer, doing what most repairers would not even think of doing!! What an inspiration! Keep up the good work. I really learn a lot from your videos. Thanks!!
Thanks for the great advice. I have the same Defy unit in New Zealand, there is no way to get a spare card. No one around here would even look at it. I followed your advice step by step and now I have a working unit once again. Thanks
Thank you so much for your work i have been repairing this fridge where by freezer was not woking i did as your shows us and it work perfectly.thank you again for your good work
Thank you very much Mr Nel this just happened to me this morning and am definitely sure will be able to do this , I just need the two components to buy and fix this .As of the next morning I will do the full check up if the compressor is working because once I switch the freezer on the board I hear something is switching on am not sure if it’s the fan inside or the compressor.Thanks again Sir you are an inspiration….
So you went back to the basics from the fancy controller that breaks a lot. Great video. You are definitely a great refrigeration tech. I like your videos a lot.
Hi, I have exactly the same fridge as the one in the video, it's not freezing at all. Opened up back panel - there is some ice on the top of the coil. Fan is working fine, Alarm light keeps on flashing.
I'm not a fridge technician but this is Genius stuff l just fell in love with how you doing it.l have a defy f640 freezer not working also. Will try it all myself thanks a lot 💜💙
Hallo Johan. We all appreciated your videos. Please explain why you dont also use a single door thermostat on this Defy side by side freezer ? On all your other videos i see you install a adjustable thermostats on other kinds of freezers, but not on this Defy. Please be so kind to explain why not ? Otherwise the compressor runs permanent without switching off. Thank you very much appreciated
The compressor will not run continuously, it switches off during defrost. The reason why I dont put a thermostat in there is because when this freezer operated with the electronic temperature controller, and was turned to maximum you could achieve a temperature of -21. By putting it on a minimum setting you get a temperature of -17 and at -17 temperature, the compressor would only cycle if the ambient temperature drops to approximatly 15 degrees Celcius. The difference between -17 & -21 is so little that to have the compressor switch off for 30 minutes during a 24 hour period does not warrent a thermostat.
Sorry I have a quick question. You say the board is cosmetic. (Just lights) But doesn't the thermostat still control the temperature. How else do you control the Freezer temperature. Great video I did this conversion. I watch your video Thankyou so much. .
Ek het presies so n defy dubbel deur yskas...Die yskas gedeelte het n interne gas lek... Sal ek dit kan regmaak of nie? Ek is bly dat ek jou video's gevind het, ek leer daardeur...Groete...
If you mean light bulb. In the fridge section there is a light bulb behind a plastic cover that can be unscrewed once the cover is removed. Just unclip the clover.
All right, Mr. Nel. So according to this modification in the freezer, the thermostat has no role except operating the PCB? Are they not related to the refrigeration circuit? thanks.
The fridge and the freezer are separate on this model. Each has its own compressor and operating system. The fridge part, I left the thermostat that controls the fridge side temperature by switching the compressor on and off. The freezer compressor has no thermostat. The only time it stops is during the defrost cycle which is controlled by the defrost timer.
I Have this fridge. Replace the PC board over 5 times and I can't afford doing it anymore. Where are you located? I want to modify my fridge like this. Im in SA
The black wire that you have put onto the defrost timer, one part will run down to the compressor the other part runs up into the roof of the fridge which you have to connect onto the gray wire once you have disconnected it from the PC Board in order to make the fan work
Hi JD. Great video.. Is there a reason that the original defrost termination switch won't work. Do you have to change that. I have followed your video and made all the changes 'except the termination switch. The freezer works great and the only issue is the defrosting. I have not connected the purple defrost wire to the timmer as I was concerned it might melt the plastics as I had not changed the termination switch will it work. Lastly what is the cost of the termination switch
Yes it is very important to have a defrost termination switch. If your timer goes on defrost & there is no ice present the 25 minute defrost period with that powerful heating element will cause damage. R171.00 is the cost in SA
I notice that this fridge has only five wires on the board, mine has 6 which is red, that goes to the door switch. If I follow your method, cutting the Black, purple and grey only affects the compressor, defrost element and fan motor, which is taken care of by the defrost timer. Won't your method affect the red wire, that is going to the door switch? Just curious about how to fix my refrigerator before I buy a new one.
The one I did had a PC board with 5 pins on it. Yours probably has the 7 pin PC Board. The only difference is the red wire for the fan which has a live wire going to the fan switch which you need to disconnect.
I did this change and the freezer started working. But after about a month, the defrosting process is failing and the pipes are freezing. what must I do to unblock the pipes,. i actually used a n 8 hour 25 minute defrost timer. Can there be a solution to keep it working perfectly again? Could the 8 hour 25 minute defrost timer be the problem or is the heating elements nit working perfectly? Assist please
Hi I also have the identical model, the problem that I have is the moment I plug the unit to the power it trips the earthleage, it was working fine, I just stopped the fridge/freezer to clean all shelfs, etc now when I plug it it trips the power, any idea where fault could be? Thanks
Johan, I have a Defy F660L fridge/freezer with a ice maker in the freezer door. The complete unit is just dead. We replaced the feus on the mother board but no joy. Can I remove the mother board and send it to some one for repairs in South Africa?
Hi Johan. Great video. I have the same defy, but the pc board is flashing the greem on/off light on the pc board. Does not bring anything on. Any idea what that means? I checked the voltage and its on 190v. Wich is obviously very low. But will the pc board pick it up or what would you suggest?
I have the single door freezer from this model family. It freezes as it should, but the compressor ran constantly, causing the electricity bill go go up quite a bit. Local repair tech told me it's the pc board. Would the workaround in the video be a viable solution to my problem? It feels like a compressor shouldn't be running that frequently?
If your freezer was running continuously it would skip the defrost period which happens twice a day, and it would build up a huge block of ice on the evaporator. If there is no block of ice on your evaporator at the moment, it means it does switch off during the defrost period. Your freezer uses about 200 watts of electricity unlike a hot water geyser that is 3000 watts.
@@JDNelRefrigeration Wow, thank you so much for replying. I have implemented this solution and so far so good, everything is working exactly as described in the video. The compressor does seem to get quite hot, but it looks like there is a relay on the side of the compressor that switches it off before it gets too hot (I think?)
I have change the pc board on this model but unfortunatly this new pc board doesnt send power to the compressor. Is there any thing to do before replace the new pc board? Or, i really have to implement this clock?
On the timer I find that a 8 hour cycle with a 23 minute defrost works very well. and the termination switch breaks contact at plus minus 7 degrees Celsius and resets at -10
Hi. Can you please advise how does the defroster work on the fridge of this unit. I recently removed the faulty fridge thermost and installed a digital one. The fridge now frosts up on the back plate.
When your compressor switches off the fridge, it has to stay off long enough for all the ice to melt off. The design of your digital temperature controller is such, that it tries to maintain a constant temperature therefore not allowing enough time for the ice to melt. If you cannot calibrate your controller for a longer off period then you will have to get the correct thermostat.
Hi. Thanks alot. As always you are extremely helpful and knowledgable.. I really appreciate it. You have helped many of us to save alot of money. In this current time we all trying our best to survive...Thanks
@@JDNelRefrigerationwill you please tell me for what parts exactly I need to ask for when going to try buying those 2 parts. The one I think you calls it a 6 hour defrost timer, but the other smal switch you mount inside on the coils I don't know what exactly to call it. Please my fridge gives problem as I'm typing on the moment. Thx a lot. Please assist urgently. Don't know if I may ask for your contact number please ? Thx
I have a defy f640 which when it cuts off it takes a long tym to restart sometimes the compressor will run until it over heats resulting in water flowing what could be the cause of this afaulty sensor or pc board
A compressor cannot overheat from running continuously, there must be other problems with your freezer if it overheats. It needs to be examined by a technician to determine the fault.
Hi Johan, please help, my fridge looks exactly like this one except it does not have the knob inside the fridge to adjust the temp of the fridge, how do you make the fridge side colder?
Timer connection 1+3 - Power - Live & Neutral 4 - Fan switch & compressor 2 - Termination switch Power to 3 on Timer Loose end of element Loose end of Fan Loose end of compressor Termination switch To element fan switch to fan motor.
The light bulb is behind the cover by the fridge thermostat. To remove the cover you first need to pull the thermostat knob out. Then there is 3 clips holding the cover in. 2 on the sides and 1 on the bottom. First unclip any side clip, then the bottom, then the other side. The cover will then unclip.
Dear JDNelRefrigeeration. I have a Def y 2 door 2 compressor. can you please advise how to install a timer control instead of the original control. thank you. Jeffrey
Hi, thanks for the video my fridge is exactly like this one the red light started flashing recently after load shedding, how do i go about testing to see if the pc board needs replacing? Do you do call outs also?
@@phprider The PC board has many functions the one I test first is the self defrosting part whether it switches the element on when there is ice build up. Once you have done that I can tell you how I test the other features. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ToO0inI2FOs.html
@@JDNelRefrigeration thank you so i opened the back plates and it freezes up perfectly and this morning there was almost no ice on the element so i take it the defrosting is working correctly, could it perhaps be the fan that is not distributing the air effeciently??
@@JDNelRefrigeration thanks im leaning towards this as the bottom part of the freezer still freezes properly, but the top half does not dont know what else could cause this besides the fan?
First remove the thermostat knob, I do it with 2 small screwdrivers which I wedge in on the sides & lever it out. Then on each side of the plastic casing is a clip. I normally undo the left one first & then through the hole where the thermostat knob was removed from, I can fit 2 fingers in there & pull the cover down. Then un-clip the right hand one.
Hie there can you please help. My double door f640 has a freezing problem on the deep freeze side its only getting cold at the bottom what may be the problem
Good day Sir i was trying to change operating sytem for double door fridge ,now my challenge is its using 12volts Fans for evaporator and condensing, is it possible to change fans to 220volts fans?
@@JDNelRefrigeration Thank you! It is a 20 cu ft single door upright Frigidaire model # FFUE2022AW. It is the model with inside control which has 'Cold, Recommended, and Colder' and runs a variable speed compressor. Set for Cold it runs from 0F to 4F, on Recommended it runs -4F to 0F. I haven't tried Coldest but advertising says it can go down to -18F. I just don't understand why it couldn't have a setting for the range from 35F to 38F!!!!
@@wailani3263 It will not make a successful fridge. In my opinion a successful fridge is a cabinet that can maintain a temperature between +2C and +8 C. The design of a freezer is such that the evaporator coil gets defrosted by a heating element which will give you a huge spike in temperature during the defrost cycle.
@@JDNelRefrigeration Thank you so much! There is a bevy of "Make your Freezer into a refrigerator" youtubes and all sorts of gadgets, as well as advisors ranging from Phd's to outback hacks but among them your presentations and solutions stand out like Mt Everest. Yes, the defrost cycle on a digital freezer and the operation of a variable speed compressor are certainly challenges to a successful and non harming conversion. Coolers have 2 sides. they cool in one place and heat in another ('heat' extraction) even speakers are 'heaters'! The 'convertible' refrigerator on the market is a single cooling unit. By pressing a button inside and holding it for 3 sec, it can switch from freezer to refrigerator and back. The mystery is "How does it accomplish that?" I had a box from the '50s that would be a beer cooler or a half a cow freezer simply by adjusting the thermostat from warmer to colder. I don't understand why today's boxes seem designed to prevent that!!! Again, Thank you.
@@JDNelRefrigeration Thank You. so basically the compressor will run 24/7 except for the 25 min defrost during a cycle? Would it not be advisable to still have a temp control in?
@@jacodeklerk4418 With a temperature controller they normally run 23 out of 24 hours anyway. So it is not necessary. Unless the client wants the freezer at a warmer temperature, then we can install a thermostat.
@@JDNelRefrigeration I asking you if is possible to change a side by side eletronic damper for one analog termostat, because I convert all eletronic pcb for a timer em bimetal, but the eletronic damper i want to change it for a analog termostat, is going to work ? I am going to put the termostat in the refrigeration part.
