My husband is an electrician and here now if that helps.

The compressor kicks on but the fan does not now.
Expert:  airheatman replied 7 months ago.
Excellent. Lets look at fan capacitor and see if it looks swollen or if you have a meter that reads micro farads check capacitor
Customer: replied 7 months ago.
It didn't but we replaced it anyway.
Expert:  airheatman replied 7 months ago.
OK if no power thee , lets work backwards .Check both sides of the ac disconnect where fuses go.

The capacitor, the contactor and the fan motor are all brand new.

What are letters in front of the 036 (EX. Raka)

Jaz
Expert:  airheatman replied 7 months ago.
Ignore question about disconnect, that was for someone else
Expert:  airheatman replied 7 months ago.
JAZ is after the 036 signifies 230 volt single phase, There should be 4 letters in front of the 036
Customer: replied 7 months ago.
That's the Ac unit model number, do you need the fan motor model number?
Expert:  airheatman replied 7 months ago.
Need the numbers before the 036.J indicates 208/230 volts. A is a series and Z identifies compressor, but there should be 4 letters in front of the JAZ
Customer: replied 7 months ago.
Also the unit is now working after resetting it so I'm confused?
Expert:  airheatman replied 7 months ago.
May have been in time delay
Customer: replied 7 months ago.
I turned off the whole split unit at the breaker box and the outside box. Then turned it back on, now it works but it's 85 in my house and I don't trust it or any Ac repair in South Florida. What could cause this issue?
Customer: replied 7 months ago.
How do I check that?
Expert:  airheatman replied 7 months ago.
The first step in troubleshooting is to know exactly the unit you have.Some have a defrost board (heat pump) , some have time delays , others do not have any. Our second step is to see where we are and are not getting voltage when it should be running and is not.
