Re: cooling

Check if the condensar ( outside fan unit) is getting enough free ventilation. IF there is no free air flow you will mostlikely be triping the unit due to short cycling. Ie the unit is pulling its own discherge air causing the compressor to trip due to high back pressure

My frigidaire AC starts cooling fine but stops blowing cold air after few minutes and it does not cool at all. I haved turned it off and re-started it and it does the same thing

The compressor is being prematurely turned off. That explains why the cooling stops after a few moments. Either the thermostat is responsible or the electronics working with the therm are responsible for the anomaly.

Freon level is fine because it does cool when compressor is running. U might also want to check the start/run capacitor. That sucker starts the motor and keeps it running after the start. If the run section goes bad the motor will usually stop after it starts.

Intertherm MGHA-070ABFC-05 will not run/cool

Multiple problems. Eliminate thermostat first. Remove face from wall and turn on breaker. If fan still runs you have a bad board or bad relay. If fan outside is running compressor should be too. These operate on same contactor. Verify you are getting 24 volts to coil side of contactor. If odf stops working and contactor remains pulled in you have a bad motor. If odf motor stops working the compressor will shut off due to overheating.

A/c will not continue to cool.. Starts fine, runs fine.. but shuts down cooling ( comp shuts off but fan still runs) after anywhere from 5 min to multiple hours. No circuit breakers or fuses blow. CAN...

One amateur test is to place your hand on the compressor and see if it
is too hot to hold your hand on it. You may have a restricted condenser coil
If it is too hot then the condenser coil is restricted inside the unit
if not be sure and clean condenser coils with good coil cleaner.
You can put a fan on the compressor and see if it runs for another test to confirm it
If this was helpful please rate me.

Cooling problem with my ac.

The start capacitor may be the problem. Is your AC a central unit or window unit? Whats the model and make? If a window unit it could also be the thermostat is defective or too close to evaporator fins. Dirt on the condenser outside can cause the motor to heat up to the point it shuts down to cool the internal overload. Let me Know, Sea Breeze

Compressor starts and doesn't stop

Relay for the compressor may be stuck ( Contacts welded) both the fan and the compressor should operate at the same time. Have the relay(s) checked and possibly replaced.

Thermostat ?

The Air conditioner are good only the adjustment of thermostat are the problem, select the thermostat in lower #3 you observe the thermostat will off in such time temperature reach to #3 If you full adjustment the compressor will not off.
In fan selector the compressor will autamatic off because no connection attached fan only .
