    If you try to restart it again after an hour of being idle, does it start? And how long does it run before stopping? If you repeat the process, does it consistently run ABOUT the same time before stopping?

It could be the CONTACTOR. It could be dirty and when the system calls to run, the contactor won't make contact and complete the circuit. Worse case scenario, compressor is siezed up. If you hear a clicking noise at the condensing unit where the compressor is located, that could be the overload protector clicking and breaking the circuit if the compressor is seized up. Good luck. I hope it is a contactor or a capacitor.

Hello sir, i am hoping you might be able to help me I have a fa4anf030 ac/heating unit, the other day the heating part of it gave out, the ac works, and the blower works, but no hot air, I've looked


Looks like a heat pump? Is the compressor running when in heating? Is the compressor running when in cooling? If yes in heating sounds as if your reversing valve is either stuck or has lost voltage. The heat pumps I'm familiar with, the reversing valve is only energized in cooling. With a meter you can test this valve (inside condenser) with the breaker off for condenser. Test the voltage on the wires leading to valve, in both heating and cooling. Should have 24ish in one or the other but not both. If yes than the valve is likely bad. If 24 volts in both than you have a configuration or wiring problem. Same with no volts at all. Do you not have back up electric heat?? Good Luck!!

MY AC WORKS FOR FOUR HOURS PER DAY AND BARELY COOLS DOWN THE HOUSE, NOT MUCH AIR COMING UP TO THE UPSTAIRS OF THE HOUSE. AFTER 4 HOURS, THE OUTSIDE UNIT SHUTS UP AND NOT MORE COOL AIR COMES IN. BEFORE THIS...


I am not understanding exactly what is happening with your unit. You say it only runs for 4 hours a day and then say that after 4 hours the outside unit shut off. But you don't describe the condition of the outside unit! Is there ice on your outside unit after it runs for four hours or is it so hot that the housing would fry an egg? Since it works for four hours and then stops working, I would guess that ice forms on the condenser grill which tells the thermostat that your air is much colder than it actually is. Then it takes time for the ice to melt off again. Am I close? If so this condition is usually caused by your unit being low on freon making everything work harder. But it could also mean that you have a leak in the system somewhere. But it shouldn't be much of a leak or it wouldn't run for the 4 hours.
I would recommend you charge it to the correct level and then check for leaks.

you have to open the unit up or atleast see if the fan is failing. The blower motor is usually a double shaft and cool the compressor and also blows the air across the evaporator. Look for the air to stop blowing then the compressor to shake from overheating.

If you have an electronic thermostat, they can short out, leaving the compressor running. Also, the big relay that runs the compressor can get its contacts welded together. See if the contacts are stuck closed.

Ac turning on and off


How did they check the freon in the home? You can feel the front(evaporator coil)coil on all four sides. Are you sure the motor is running fast enough? If the four corners do not feel cold in about 5 minutes or so, there is a compressor problem, Capillary tube blockage, moisture in the system or you are low of freon. Good Luck
