Lennox Heat Pump Package Unit Not Cooling | HVAC 

If you'll get yourself some Jumper's you can start jumping out one thing at time and see what works and what doesn't. Also after you seen you had high voltage you should check that you have control voltage or 24 volts or transformer pwr. All the same thing. If you have control voltage coming out of the transformer then start checking the board after delay to see if you have outgoing power from the board. If you do then you have a component failure. Another thing when you're looking at breaker's look closer to see if they've been tripped or if someone actually turned it off. A tripped breaker is a big giveaway for dead compressor maybe even locked up blower.

Glad to see you check the wire size and note it. The wiring diagram will tell you all. Rewire inside the cabinet if you must. Done it quite a bit after a visit from “handymen”. That 50A disconnect needs to be changed. If you have sand cloth, sand the dirty or corroded plug ends on the fuse holder. Help with electric flow. Nice vid.

Just hearing the dog reminds me why I will always hate residential work.

Good job figuring that one out!!! 😊

I watched twice and you lost me on the wiring. I don't understand why both disconnect can't be on. I think the maintenance guy the customer was talking about screwed something up but cheers to you for getting it running at all. You'll probably be back in the fall to fix the heat.

That empty mulex plug looks looks like the one that went to a 12j99 control boad for lennox gas package unit?? I swapped one the other day that had bad blower relay on the board...good job staying with it! Rats nest wiring and hacks= hella trouble shooting nightmares!!

Great job sticking with it bro.

Those window AC units tho they are great for back up

My mother told me there'd b dayz like this. It sucks working on a unit like this that has had bad maintenance and poor conditions.

This one confused me... nice job getting that thing up and running again.

🤟💯🌎

That was a Ratdog barking.

Uh... did I miss the delta T?

Nice job for working on something you hadn't seen before. Did you actually end up cleaning the coil(s) ? I know you talked about it.

The 60 amp was just for the heat pack and the 30 amp is for compressor. Seems to me someone messed with the wiring at the contactor and had both services supplying contactor therefore they canceled each other out. I think thats why they had one turned off.

Fix my living situation ... SO, did SHE kick you out?

Gosh, that unit wasn't sitting on a pad and looked to be sitting in a puddle of water. Could that have any effect on the electrical system? I'm no expert but was just curious.

What state are you in?

You must be a beginner
