If unit hasn't been running for a while, shut power off to it, and go up on roof and take a long stick or similar, and try to feed it through air slots in cover at back and try to spin the fan enough to rotate it 3 or 4 times. Then have someone turn power back on (with stick out of there obviously) and try turning on fan mode only to see if fan will now come on. If it does, run it for a few minutes then try cool again.
Sometimes they get a dead spot from not being used for a while, and this will get it going again. If you have trouble rotating it, remove cover and spin by hand well, but make sure power is off, then try it again. If unit was running recently, have capacitor checked first, then fan. Capacitors can give off a very dangerous shock due to high voltage stored in them, so don't try it yourself if not familiar with capacitors.

GE Profile - model PDS20SBSALSS - constant clicking noise


The clicking is the compressor trying to start. If the compressor is extremely hot, try allowing it to cool. The condenser fan should run even if the compressor is out on overload; that may be the cause of the compressor failure. Check the supply to the fan and replace it if it doesn't run.If the compressor has been overheating for some time, it may be damaged and also need replacing.

On 12 year old AC fan works, but there is a periodic muted buzz but compressor doesn't engage.


The hum is generally attributed to the compressor trying to start- being intermittent suggests it is failing and going into a delay via an internal safety switch. Assuming this and the fan you speak of is the condenser fan there are 2 good diagnoses- either the run capacitor is bad or the compressor is locked up. I would change the capacitor and install a hard-start capacitor, if the problem persists it would most likely require a new compressor.

Compressor comes on for about 1 minute, but fan doesn't. Then a sound like a pressure release valve opening starts and will continue until you turn the unit off. The unit will sometimes work normally...


The sound is from the compressor high side pressure exceeding design limits due to the fan not operating, the fan pulls air across the coil to remove heat from the freon which keeps the pressure down. The capacitor or fan motor may be bad. Need to open unit panel and visually inspect the capacitor for swelling, (rounded top should be flat) where the wires connect. Also use meter to test mfd of capacitor. May only need capacitor replacement, most common failure on this unit.
If not corrected damage can be done to the compressor due to overheating.

Hi, I have an amana ap125hd portable air conditioner and for some reason is doesn't produce cold air anymore. Then fan blows and the compressor kicks in, but to no avail, no cold air. I took the unit...


replace it,most likely the freon leaked out,if the compressor is running and the fan is blowing but not getting cold most likely you have a leak in the sealed system.

Refrigerator does seem like its working right


Your refrigerator compressor is either pumping or it is not. Set the refrigerator to low temperature, pull it out and listen for a while to see it the compressor is coming on. If it is coming on then there may be a freon leak or the internal coils may be iced up. If it is not coming on, then either there is no power to the coompressor, or the compressor itself is defective. Use a voltmeter at the compressor to check for voltage. There is also an add on device to start stuck compressors from your local HIVAC jobber store.

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.
