RVComfortZC thermostat goes to OO and freezes

[Bearman2737]

My Fleetwood Revolution motor home has an RV ComfortZC thermostat. Occasionally the zone reading goes to OO and everything shuts down until I remove the fuse, wait, and replace the fuse. I called the manufacturer and was told that the electrical circuit was dirty with a bleed from some other electrical system. Can't find the culprit! Any ideas?

Fluorescent lights fixtures (the ballasts) can cause noise in the 12v circuits.

This is what happened with ours. Had to replace 2 fluorescent lights. Then I replaced the third one, just to not have to later. Ours is an 03 Fleetwood Providence.

There is something called a choke filter that you can put in line.

I had the same problem when my MH was new. Happened while running the furnace and the nearest florescent light to the tstat was on. Light mfgr. sent me all new light fixtures and also Fleetwood replaced the Comfort tstat. Still failed. I was then sent, by the light mfgr., the choke mentioned by Clifftall, and haven't had the problem since.
