Question about Heating & Cooling
I've always been a "do it yourself'er" but I've been beaten by my A/C and I need professional help. 2 weeks ago I noticed I wasn't getting cold air. Inside unit/fan was running, thermostat showed it was trying to cool, but I wasn't getting cold air. Checked outside and unit wasn't running. Turned it off for a night and when I kicked it on the next day, it ran like a champ. Of course, after several hours, it did it again.
I called out a repair man when it was running and he checked my pressures and coolant and everything was fine. He thought it was my fan motor overheating, but honestly wasn't sure. I pulled out the motor and it had no drag, would spin freely and made no sounds while powered. (I thought dying fan motors sounded like they were dying.) So, I began troubleshooting everything else...
I took my run capacitor to an A/C shop and had it checked. It was okay.
I replaced my contactor because it looked rough. I installed it and it ran fine for a day, then same symptoms so that's not it.
I added a Pow-r-pak boost because this must mean my thermistor going out and it was due to my pressures not being balanced, right? STILL no luck. Same thing. Ran fine for 4 hrs then died again.
The only other thing I think it could be is my compressor time delay relay. Is that possible? Or, could it really be my fan motor even though it doesn't feel very hot and it's not making noises?
Looking for help. Thanks in advance.
Change the fan because its not condensing that's why when get hot the coil turn off

When you check and find out door unit not running you need to check if the two wires coming from inside (thermostat then down to heater then out side) has the voltage to turn the system on. For most outdoor units this would be 24 volts ac. Then any time delays and safty controls can be checked. If you do not have power then trace back to heater then thermostat.
