If it isn't one thing... now it's the tankless H2O heater
^^^ Exactly what he said. Execept you don’t want to switch the power off if there are any chances of freezing temps.... unless younplan to re-winterize.
And.... you should have had the power off on the outdoor unit after winterizing. Otherwise the freeze protection would try to run constantly if you live in cold temps.
A dealer once winterized another coach I had and forgot to do this. They didn't out the Use / Store switch into the Store position during the winter when they had it and I had solar installed. So the blower motor ran most of the winter when temps dropped into te 30's and was shot in the spring when I got it home and I de-winterized it.
