2019 THOR® MOTOR COACH QUANTUM RS26 HEATER ISSUES

[ILLUMINATUS]

Hello everyone … I’ve experienced no issues with our 2019 THOR® MOTOR COACH QUANTUM RS26, and have had success with the use of the heater during winter, at TRUCKEE, CA. during prior winters, but this year, after turning the heater on, it jus’ blows CLD air … I can’t remember if I had to run the generator to receive heat from the heater, or not.

Any assistance or suggestions, would be greatly appreciated

Thank you,

GIOVANNI

What happens when you tried the generator?

I assume you are talking about the RV furnace, not the cab heater?

No generator needed, just 12 VDC from the house batteries and propane.

Does it just continuously blow cold air? Or does it blow for a minute or two, then stop, then try again?

I assume you have a propane furnace - which should work on 12V (IOW, not needing shore power or generator operation). If you have electric heat, then I don't know anything about that (but would assume it needs SP or generator running).

If, indeed, it's a propane furnace, first question is do you have propane in the tank & is the main valve open? If the cooktop is propane and that works the propane supply must be OK. The furnace will typically start by switching on the blower then the circuitry opens the propane valve & the ignitor sparks to light the burner. There is a sensor that tells the circuitry everything is working. If the burner does not ignite then the circuitry shuts everything off. Thus, many things in that sequence that could be not working that will prevent you from getting heat.
