My air conditioner typically runs fine, but recently about a week ago in the mid afternoon it shuts off and I have to go out and push the reset button on the back panel of the outside unit. It starts up and runs properly for about 20 hours or so, then shuts off.
I had my normal ac man come out and check everything. I had cleaned the coil and replaced the contactor, earlier. Anyway, he says the unit is working fine and gave it a clean bill of health, only that it was an older unit of 12 years old. It had full coolant, fan motor runs fine in both the outside unit and upstairs. The only thing he said that was slightly high was it was pulling 22 amps and not 20, but that was normal for the 105-6 degree days we are having in Texas. 2 -3 hours later it turned off again, I turned off the thermostat, pulled the breaker and put it back in, reset the reset button, turned back on the thermostat, 5 minutes later it starts up and continues to work fine.
Do you have a possible suggestion?
