Furnace Lights After Cycling the On/Off Switch

[Imahokiefan03@aol.com]

Hello, I have a2021 keystone montana5th wheel. The furnace turns on but does not ignite. I open the cover on the outside and there is an on off switch. Turned it off for 10 seconds and then turned it back on. Then turned the furnace back on and it ignited. It heated the camper back up but when it got below the thermostat temp it cut on and ran for about a minute blowing cool air but did not ignite. Would anyone know what this could be?

Hokie, this is a 2009 thread. A few things to check. First, if it is not already replaced, change out the 15 amp self resetting fuse for a regular 15 amp fuse. Second, make sure there is no air in the lines. Run your burners for a few minutes. You did not mention if it tries to start and doesn’t. Next easiest thing to check is the sail switch.
