Hi all.
So last night we are watching a movie on the TV. Nice evening, cool enough to not have the air conditioner on for a change. Just the trusty Onan generator running. So suddenly the air conditioner display starts blinking all sorts of lights and there are clicks coming from the control box. I'm like what the hell it's not even on, but jump up and shutoff the breaker. Sure enough today it's dead as a door nail! Called Dometic and another control box should be here by Tuesday. Weird though how the circuit board apparently got fried when the unit was not even turned on? It's been working just fine for over a year. Even the guy at Dometic didn't have an answer for that one. So I'm wondering, how does that happen? The generator is an Onan 4K
MDKC 1987 vintage. The air conditioner is. Dometic 16k just over a year old.
I'm thinking maybe a power problem with the gen? Reason is in addition to what happened, on generator power my battery charger, a master volt 40amp works just fine until absorption phase is reached at which time it, after about a half hour, shuts itself down too. I've never had any problems for years with either on shore power, and I've been running the AC for weeks on generator power and the only issue a few times has been a high pressure fault. After cleaning everything related to water flow, finally putting a fan blowing on the compressor seemed to do the trick...until now...
Any advice, suggestions would be much appreciated.
Thanks
