Hey there, I'm a Field Service Tech fixing things. Videos posted for techs, by a tech. I work on barguns, coolers, fountains, ice machines, slushy machines, coffee machines, etc. Message or comment on any issues or questions and I'll try to address them. Suggestions are also appreciated. Please don't attempt repairs if you are not trained or knowledgeable, there's a lot more to fixing things than what I can show in a 3 minute video. Thanks and stay safe out there.
Two questions. Can you make a video on how to flush out the lines? Also for someone that isnt in a commercial setting(if it matters) since the brix changes on an expired product, can you still use the expired product if you adjust the brix concentration to reach the 14%?
I got one on marketplace for $100 and he said it was doing the same thing lol. I’m going through trying to troubleshoot everything. Did you find a solution?
@@jacobbarnett9956 I feel you lol. I spent 45 minutes cleaning the inside and I slide the compressor out and blew everything out and started learning about how to fix a fridge. Whole new skill I’m learning right now lol. I’ll update if I find the easy fix for it
I have a Bunn ultra 2. It just recently started taking a long time to freeze. I checked torque and temp readings. But sides had refrigerant flowing. One side drum was able to get down to 15 degrees and ended up freeze after about 5 hours. The other side drum never got below 25 degrees and product never froze. Any idea what could cause that?
How long should an ultra 1 take to freeze 2 gal of product that was added at tap water cold temp? Mine did not start to make any ice at all until about 90 min...and at the 2 hr mark is still hardly frozen. Drum temp seems to be sitting at a steady 28 degrees...but took over an hour to get there. Hot gas started at 127 but now currently is 86 to 88. Do these numbers seem right?
We have an ICEE FBD for our Little League. Do you recommend purging like the video for our offseason? During the offseason (a couple months) we wouldn't be using the machine.
Leaks are kind of rare. 9/10 it's a component along the way. Condenser fan kicked on, so t-stat seemed ok. Pressure isn't something you want to measure unless you suspect leak, you never really want to open these up. Parts cost, no idea but it's easy enough to find. You can get a hard start kit with your specs and it's cheap and easy to find and will solve the problem, though not ideal.
@@damianflores2091I believe these are retro looking coolers? If so just start with the simple diagnoses. Is there power? Is the evaporator fan running? Is the evaporator frozen? Is the condenser fan motor running ? Is the compressor running? Is the condenser coil dirty? If these all check out it’s most likely something relating to the refrigerant. And you would have to gauge up. If one of those questions above does not meet with the requirements then it will be something in that field. Bad fan motor, bad starting components on the compressor (as seen on the video ) or a bad thermostat.
@@TheDave5619 Got a GDM-15 Retro not cooling with a PF2 (faulty condenser temperature) message during test. I believe everything else is working. Compressor, fans (cond & evap), lights are turning on, everything is clean.. Thoughts on how to troubleshoot further?
@@TheDave5619 Thank you for the reply. I actually figured out the PF2 mystery.... There is no sensor connected to the EMS controller. So it's only "natural" that is is giving a PF2 message! :-D My next step is to figure out why it's not cooling. I get some warmer copper tubing going to the condenser and the copper tubing coming out is colder. I havent had a chance to measure the exact differential temperature just yet compared to the air in my workshop so it's my next step. I suspecting that the unit might need a reload of freon since it does not show any signs of having been serviced since 2016.
Thank you John! I have been struggling with my Bunn DBC for months now and your explanation of how to remove and descale the solenoid really helps, I will be attempting this sometime this week.
Hey my bunn isn’t freezing my product, I removed the liquid and turned it on the center barrel gets frozen but not the whole thing maybe 3/4. Would that be a solenoid issue?
Not a guarantee. Call Bunn and check resistance between the terminals. 90% of the time one barrel down is torque sensor issue. First thing to check is the auger rod pins and eye that read the distance between them in the back of the machine. I'm trying to put a quick video together for that.
From what I can gather the tanks provide the space for the product to expand when it freezes. Think about what happens when you put a can of soda in the freezer-it expands till it explodes. There's a diaphragm that flexes instead of exploding though and it has CO2 pressurized on one side and on the other side is the product. When the barrel freezes down, the product expands and pushes out of the barrel and into that space in the expansion tank and pushes against the diaphragm.
