gas heater

[olly72]

Hi all: When I try and turn on my gas heat I hear a click inthe thermostat but neither the fan nor the heat comes on. This has just started since we used it three weeks ago. I have a Coleman Mach True Air model 6535B335 thermostat. The propane is on as the gas water heater works. Any suggestions will be appreciated.

I would check the 12V fuses first, then the connectors down in the furnace compartment. Wouldn't hurt to check the house battery voltage either. If your converter isn't working, you can be fooled into thinking the batteries are fine since everything in the house keeps working, for a while. But when you try to run something big, like the furnace, it won't start. Converter not working can usually be traced to a GFI.

hanks guys got the solution. Found my heater blower from the reaar of the motor home. There is a plate with the vent holes and tag attached. removed the plate and there is the blower. A switch that has a lever that pushes a small button was stuck. cleaned it and now everthing works. Thanks again.
