rtjennin Report post Posted October 12, 2011 I have an Atwood Hydroflame furnace in a new Fleetwood Class C. I can't get the furnace to work. I have followed the operating instructions. The blower will not come on and the burner will not ignite. There is a switch in the outside access panel, with "on" and "reset" settings. I have moved the switch from on to reset and back to on.

wolfe10 Report post Posted October 12, 2011 Verify that you have 12 VDC to the furnace (outside access door). Verify that the thermostat is working (signal is arriving at the furnace). Remove the electrical connections at the PC board (outside access door) and gently clean-- DeOxit from Radio Shack,etc is very good at insuring good electrical continuity.

How do I tell if I have a signal from the thermostat? Your setup should supply 12 volts to the the furnace from the thermostat., but some are connected to a EMS system and it supplies the 12 volts to the system. Supplied more details on the other thread you posted the question on. Rich. Share this post Link to post Share on other sites
