Okay, grab a drink and just bear with me while I try to explain my issue.
2020 Keystone Cougar 368 MBI with 2 Dometic A/C units, fully ducted and operated off InCommand system.
We purchased this 5th wheel over the winter and during a trip in March on a warmer day we realized the front bedroom A/C was cycling off/on a lot. It would run for 15 minutes or so then cut off, cut back on for 30 seconds then back off ect ect. Took it to dealer after the trip and the running capacitor was bad so they replaced it and said it was good to go.
We're now on our first summer trip (We live in Georgia) And its been mid 80's to low 90's during the day (60-65 at night) and the rig has done a wonderful job at staying cool during the day (we keep them set at 74 during the day). First night we set the rear AC to 72 on AUTO fan. It stayed between 70-72 all night and never came on but a few times. HERE IS MY ISSUE- The bedroom A/C i set to 70 (when we went to bed it was 72 so didn't think there would an issue with 70) and it ran for about 20 minutes, got to 71 and cut off. Then 1 minute later it would turn back on, compressor kicks on for 5 seconds then compressor kicks off and unit turns off. 1 minute later, unit comes on, compressor kicks on, runs perfectly for 5-6 minutes, then cuts off. I check temp on my InCommand App and its 71 but set to 72. It does this for over and hour and i can't sleep so i change the setting to 71 since its 71 in the room. 20 minutes goes by, turns on and proceeds to do the same routine. Comes on, compressor kicks on and runs fine for 5 minutes and cuts off, room shows 72 but set on 71 so 1 minute later it comes back on, compressor kicks on then 5 seconds later compressor kicks off and unit goes off. The air is cold, it works fine...But i think there is something wonky with the temp sensor or something?
Basically, it the heat of the day or if the unit has some work to do to get to the set temp it runs great. But when it gets close to the temp its set at, it is losing its mind. I have no idea why it would come on and the compressor kick on and off in 5 seconds, then come right back on and run fine.
Has anyone else experienced this? I'm to the point where i may just set the rear A/C lower and cut the bedroom one off at night. You would think it would come up and cool the room off good and just cut off. But the short cycles are what makes it impossible to sleep ..
