Only one zone works RV Comfort .ZC

[jmuir26]

I have not been able to of find a fix for RV Comfort .ZC. What happens intermittently it will not switch zones. The only way I have gotten it to work is to switch off the Aux Battery switch. I have read lots of posts on the issue and have no solutions. I own a 05 Fleetwood Providence. Thank you ahead of time for the help.

Hi jmuir26,
Consider asking the moderators to move this thread to the Fleetwood Owners forum, on iRV2. (The little red triangle at the lower left of the screen). The answer may be specific to how Fleetwood wires the HVAC.

Remove cover from the thermostat. Turn power off to the thermostat. Carefully remove the old style fuse (glass with metal at both ends). Note that the U shaped fuse holder has two metal contact points at each end of the fuse holder bracket. Both of these contact points must firmly meet and retain the fuse at the metal ends of the fuse. Bend the U shaped tabs if necessary to insure proper electrical contacts. You should now have both Zones operational after replacing the fuse ,cover and turning power on. You cannot change the zone while the white light is on. It takes a little time for the light to go off. After this occurs, you can now select the other Zone and make control changes on the newly selected Zone. Good luck!
