There are many possible reasons why it happens that way. Basically, when the unit have reached the desired room temparature,compressor stops as will as the condenser fan.Please try to set your thermostat at its coldest setting, if the fan at the outside condenser still stops, consider replacing your thermostat, it migth be defective.

Suction pressure is growing upto 80,85,90...etc,then the compressor cutoff soon.what is the reason?


Compressor must be over heating. Check the rear coil and see if it is stopped up with dirt. If you are trying to add refrigerant with a stopped up condenser coil, you could damage the compressor. Make sure the rear coil is free from debris and can exhaust the hot air efficiently. Hope this helps.

I have a window unit in which the fan appears to have stopped. It is a eight year old unit but was working fine last season. It was when I started up this year that this occurred. I also noticed that it...


The reason your breaker is tripping is when the fan stops running the compressor is having to run at much higher amps than normal. The replacement of the fan can be very difficult to reasonable. The fan sometimes can be removed then cleaned up (remove all dust, lint) then just lightly oiled to free it back up. Good luck and try to have fun.

24 btu air conditioning unit. After two hours it stop working.


You should replace the return airflow sensor. Sounds like it is not cycling on temperature and therefore overheating the compressor. which will shut of on overload.

Fan won't stop on Maytag M1010


Some thermostats have a fan switch that turns the fan on to run continously. Check to make sure the fan switch is not turned on.

If thermostat is not the problem, then somebody will have to troubleshoot the control wiring to find the reason for the fan issue

Stops for no reason when on cool


I would say by the sounds of it the unit is short of gas, the compressor is getting hot and going out on thermal overload. I would think that it would be best to call a refrigeration tech out. As I can not help to much with out looking at it.

If there is anything else I can help with or any other questions please let me know

Lg split indoor fan runs non stop


Hello Hamid,
The unit is designed to run the indoor fanmotors continuously when in cooling mode on both indoor units (evaporators). The reason is that this circulates the air and the temperature thermistor or sensor is able to sense return air temperature and in turn start or stop the outdoor unit and compressor as required according to the setpoint temperature. The reason for either unit not reaching setpoint temperature can be a couple of reasons. A) Incorrect design - the unit may be too small for the application. You can calculate this roughly at 650BTU per square meter of room in a relatively warm ambient climate. Or secondly B) The outdoor unit has leaked and is short of refrigerant. You can check this when the outdoor unit is running by feeling the thicker copper tube on the right hand side of the unit. This should be cool to cold. If no temperature difference is felt, it is short of refrigerant. Hope this helps you. Goodbye
