Lugging compressor on start-up

The compressor sounds (loud) and lugging while trying to start. In a few seconds, it kicks off and the fan continues to run. What is your opinion??

It may also be that your Start Capacitor has failed. The Start Capacitor provides a boost in power to the compressor when it kicks on, in order to overcome the high power demand on starting. Call Dometic with your unit's model number and they can help troubleshoot and/or supply parts.

My DRB1901C is not freezing. It's sounds like its trying to kick over for a few seconds then fails.


If neither cooler or freezer is working it sounds like the compressor is locked up. When that happens it tries to start and will hold the start capacitor in until it overheats the safety contacts. It will overheat in about 3 seconds and then kick out. This happens sometimes if the door is opened right after the compressor has turned off because it is cold enough in the cooler/freezer. However if this continues time after time and the compressor does not start, you probably need a new compressor. You may consider a new refrigerator, since compressor changeouts are fairly expensive.

it sounds like your compressor is failing to start ... that usually means a bad starting capacitor ... if thats the case it will hum loudly for a few seconds periodically .. thats the compressor trying to start but it cant if the capacitor is bad .. it will stop humming when it gets too hot .. a thermal breaker will turn off the power until it cools back down .. dont let this continue since it will eventually damage the unit ... replace the capacitor .. the capacitor is usually mounted on or near the compressor .. it often has two sections .. one for the fan motor and one for the compressor ... since they are both in one case you have to change them both ,...

I turn it on (montana 5th wheel) and it sounds like it's tryin to kick in the compresor that is and the fan comes on and the compressor tries to kick in about every 30 seconds but cannot?? it's about 4...


The compressor is trying to start and cannot because it is broken inside and will need to be replaced. The compressor can be replaced by most anyone that is familiar with working on home central air conditioning units. I have replaced a few compressors for units like yours. Have a professional check it out. It could just be the start capacitor, but usually it is not.

When our refrigerator kicks on, after a minute or two it makes this loud whining, from soft to loud, that lasts about 2 to 3 seconds and does it continually till it kicks off. It's like, Waaaaah, waaaaah,...


This sounds like a compressor that is whining. Or something maybe wrong with the fan motor. You can stop the fan to see if its still there. If it is then its the compressor making the noise.

Compressor wont start


It is probably a failed run capacitor for the compressor. Without the capacitor, the motor can't even try to run, but it will draw extreamly high amperage until it trips the thermal overload (avarage trip time 5-10sec) after it has a few second for the safety to cool off, it will try again. Either that or the compressor truly is seized
