Heat thermostat won’t turn on
We have a Relefction 320 MKS. We just got out of storage and all the electrical works fine except for the heat register which will not turn on al all - we have it hooked up to electric and the props and turned on and nothing. Any help appreciated!

What are you calling a "heat register" - the main furnace?

@Chidalgo71,
You can use the "@" plus the members user name (in my case, Second Chance) to tag someone. You can also use the "Reply With Quote" (as I have done here) and the other member will receive a notification.
Now, to your problem... the furnace requires 12 volts DC to operate the thermostat and control board. If you have house lights (like ceiling lights), you have 12 volt DC in the rig. There will be a blade-type automotive 12 volt DC fuse in your main power center labeled "Refer/Furnace" or something to that effect. Pull it out and examine it under good light. The little metal "U" inside should be continuous without a burned gap in the middle. If that fuse is not burned out, I would next suspect a problem with the control board on the furnace itself. If you're not comfortable trouble-shooting that, I would call a mobile tech. If your RV is still within the 1-year warranty, be sure to call GD customer service first to get the repairs authorized.
