Question about Dometic Rooftop RV Air Conditioner

1 Answer

Sounds like A/C compressor goes on but fan doesn't. Most times compressor doesn't even start and I just hear a "clicking" noise when I turn on the A/C from thermostat... Breaker is OK.

The clicking noise is the contactor for the fan and compressor. First take a look at it and make sure the contacts are ok. Turn the power off first. If the contactor is ok then check the capacitor(s). You can check them with a multimeter with the capacitor check function. You can also google "check a capacitor". If that doesn't get it let me know.

Mr Kenmore refigerator started making a loud SNAP when the compressor starts and stops a while later. This apart from the fan noise. Relay?


Sounds like the compressor start relay might be the culprit. It generally clicks when the comp turns on or off but you normally do not hear it.

Not freezing or cooling and compressor clicking on and off


From your description it sounds like the start components (start relay, overload and capacitor) are having problems. The clicking you hear is probably the overload kicking out to protect the compressor. It is quite possible that the compressor simply has gotten too hot and after sitting a while will restart when plugged back in. The start components are not generally considered 'user serviceable' parts. When the compressor has cooled to pretty much room temp, plug it in and be listening for those clicks. If you hear them, unplug it because it could eventually damage the compressor. Those components give the compressor an extra jolt to get the compressor running then they drop out of the circuit. If the compressor doesn't start, it creates heat until the overload drops out.

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.

Ice in icemaker is melting. refigerator is making buzzing sound for several seconds at a time like a faulty switch that is having a hard time making contact.


it sounds like the compressor is the problem.
1. is light on in side when you open the door. If not check breakers or fuses.
2. Can you hear the compressor running. If not do you hear any clicking sounds.
3. If you hear clicking sounds, try putting a fan on compressor and unplug refrigerator.
4. Wait one hour.
5. plug back in. If compressor starts let it run and see if it cools, if it doesnt, call service man.
6. If it goes back to clicking, call a service man.
