Question about Dometic Rooftop RV Air Conditioner

1 Answer

A/C runs cold when first turned on. Will run fine for about 1 hour, then the compressor starts to cycle on and off. Will run cold for approximately 2 minutes then compressor kicks off for about 4 or 5 minutes. Compressor then kicks back on for another 2 minutes and then kicks off. This cycle will continue for as long as you leave the unit on.

It sounds like your unit is low on refrigerant. Have it checked and refilled if necessary.

2004 sebring air conditioner stops and starts


Low freon will cause the compressor to short cycle, when the compressor runs the pressure in the low line is pulled down and the low pressure switch turns it off. Not running the pressure builds up and turns it back on. In the old days there was no low pressure switch, with no freon to carry the oil the compressor was destroyed.

Refrigerator compressor won't run


Plug it in. It may be in Defrost cycle, nothing runs when in defrost cycle. Amana's are famous for defrost terminators to go bad. The fan in the back should be running even if the compressor is bad. Do you hear a clicking in the compressor? If so the overload in the compressor is bad.

you can replace the relay with a 3 in 1 made by supco. i generally just use a supco 0410.

Kenmore AC compressor on and off while outside unit fan running


If the out door fan keeps running and the compressor cycles off that would be the overload in the compressor.
What keeps the windings cool is the refrigerant back to the compressor.
For the overload to cycle it would have to be either not enough cooling back to the compressor or high amp draw, which could be the metering device (txv or orifice) or low on charge, or other things would be a bad capacitor, sometimes a bad start relay not staying open, when compressor gets up to speed or anything causing the compressor to draw high amps.
To check the refrigerant, he needs to check the superheat at the compressor it should be appoximately 12° to15°, and next time the compressor goes off if you shut the power off and feel the top of the compressor and if it's hot 130° or higher it's probably refrigerant.

Fridge cools for awhile then compressor cycles on and off


Not the compressor. Two reasons why. If your compressor was bad, you would not hear it at all, also the compressor would be very hot, do to the piston not moving and the shaft just moving or the liquid not turning into vapor. One way to check for sure is to take a multimeter and see your voltage. You can also touch the suction and the liquid line, if one is cold and the other is hot or warm then compressor is working ok. Also when you unplug the system and you reset everything, you are not reseting the compressor you are reset the relay

Kenmore model 253 fridge cools then issues....


Ye, try to first replace the Relay, if that does not help then go to the run capacitor. Those are going to be your only 2 problems that you will have as long as the compressor is still doing its job by atleast running

It is definitely with the compressor. It should more like you may have a weak winding in the compressor, you can a hard start capacitor (sp5 ) that will help the compressor on restart. Note that this is a last chance solution for a compressor.

Side by side not cold


compressor overheated or stuck. also check starter relay...maybe broke.
if ever thing is alright,

let it stand for about 4 hours unplugged to cool the compressor.

plug it after 4 hours and if the compressor would still run for 10 seconds, then you have a faulty compressor.

tnx 4 using fixya,
