How to initiate Forced Defrost and replace defrost thermostat? 

Simplified, Informative, and straight to the point. Just another awesome video 👏

Dude your camera action is so good, and you're such a gentile good schooler. I hardly ever see HP's in SW FL. You get an atta boy for doing such a good YOB.

Is very straightforward Especially on the evaporator and condenser and how they change with the reversing valve You're giving up great videos simple examples and direct

Your video of on the job defrost initiation was very well done. Thanks.

Good little demo Tabby ... Thx for posting ...

Watching from Paris nice job you're a teacher for sure.

Nice as usual I just learned how to jump a defrost board temporary till a get a replacement 👍🏼👍🏼

Great video!

good video ,clear and straight to the point

Hi, so during defrost the indoor coil is cold AND the auxiliary heat is on at the same time? So you have very hot air going across the cold coil? Thanks for your tutorials.

Most parts I get I am lucky I get any paperwork. Sometime the stat is knocked off and I have no clue where to put it. I have typically seen them on a condenser(evap in heating lol) u bend. Mini splits are taking over and I am trying figure out how to diagnose their defrost. It’s defrost season lol. I had a nightmare with a WIF defrost clock on Friday. Found out I forgot a jumper between 1 and 2. I found indoor/outdoor coil easier to understand. But from a technical standing it is important that people understand that they switch. I actually have to go back to a Lennox fan/defrost issue and their tech support is impossible to reach. Tomorrow I have two HP icing issues lol.

Very good information. Thanks for the advice. I have a question My AC unit make a very loud noise when kicks on it is like 4 months old. I don’t know how to fix that. At this point two technicians still my money trying to fix it but I still have the issue. Any advice. Thank you. It is a Goodman 3.5 tons AC gas furnace

Awesome video !

Would like to also watch members only videos, Thanks for all the info.

Can you please tell me the name of the book that is in this video, thank you.

Thank u from the incite.

Thanks tadd, I learned how to huck up gauges during heat mode, how do you determine unit needed new thermostat sensor and new control board.thanks for Sharing knowledge 🙏🙏🙏.

Thank you It helps

Tanks Great video

I learned about the "test" feature, but would like to see closer details on where you jumped between the defrost terminals

Learned how to ohm out that the DF

Please help me. I try to 3:24 troubleshooting what is going on with my freezer ( it all in ice). I checked all sensors, and defrost sensor was always close. I order new one and when it came firs of all i try to check continuity and I have it. So this one is close too, so i order another one. Another one have continuity too, so right now i doesn’t know what to do. Model of my fridge is GNE25JSKGFSS and number of thermostat is WR50X10069 / AP3884325.

Nest T-stats don't have aux Or EM to use.

What would’ve happened if you hadn’t connect those jumpers for the defrost thermostat? And instead you would’ve DT already on place.

If overnight the defrost comes on, but continues to blow cold air into house for over an hour, what could ve wrong? In Phoenix there is now aux heat

Can you explain why you changed the defrost board when you determined it to be a bad sensor? I've seen this a lot and I'm not understanding why both are often changed together. I'm trying to learn.

Hi. I love your videos. I've replaced my run capacitor, and the run stop capacitor. And the outside fan turned on for about 3 seconds and shut back off. Now the outside fan won't come on. It's just that loud hum sound. Is it stuck in defrost or something? Please help. Thanks in advance

Usually the unit outside Coil is hot and the vapor Inside the home is cold when it's Winter and it's a heat pump And it's in heating mode the outside cool becomes cool and The inside coil becomes hot

On my heat pump the defrost thermostat is attached to one of the u shaped copper tubes on the ends of the coil,it’s like that factory is that right,the reason I’m asking is I need to replace mine,I’m a sparky not and hvac tech and it’s my unit ,we had a cold snap and my heat pump became an ice block

Ey brother Are you the home depot comercial Voice???

thanks, I tried jumping the speed up pins and nothing.. I also removed the defrost sensor and jumped them pins before speed up. Still nothing. I also changed the DF board.. still no defrost. Weird might call in a tech

Said no power to the rv, what if rv is energized in heat mode?

Change those batteries in your gauges. Lol.
