Newbie here.

My unit only has 1 of the two fans running, problem in hot weather.

Thinking this would be easy (and thinking with my hands), I replaced the fan motor. No joy.
Tested motor start cap - OK.
Now have the PCB out and testing relays.

Anyone have a circuit?

Don't worry guys, I fixed it.

Relay K1 had open circuit contacts. Replaced it, all good! System pulled whole house down to 18 degrees last night in test.

Anyone want a fan motor for one of these? Going cheap!
