GS Friendship 8408 Rear Furnace

[ryananddavina]

2003 GS Friendship 8408 - cannot get the rear furnace to come on at all - the front comes on when set to furnace and gets warm but any thoughts on the rear not even doing anything? I turned the rear thermostat to furnace and the temp down and nothing

Wouldn't you turn the temperature setting UP to get the furnace to run??

I did have a failed thermostat in my TourMaster keeping the Air conditioning from running properly, so these controllers do stop working from time to time...

Well that is what I thought - the A/C comes on when we lower the temp and switch to cool but nothing when we raise the temp and switch to furnace - absolutely nothing - checked the fuses and they are good to go

Do you have the climate control thermostat? Where the mode button shows a/c, fan only, furnace. Also zone selection

[ryananddavina]

I have ac off and furnace then auto and on for the fan that is all that is on the front of the thermostat

[Towboy]

there is a small fan control circut board on the furnace check for voltage there. Could be a bad board.
