Furnace Ignition Problem

[billberk]

I’m having an intermittent ignition problem with the Atwood furnace in my 2007 Safari. The blower comes on and I can hear the clicking sound of the igniter. It tries to light three times and then gives up.

After I turn the thermostat off and back on, and hit the reset switch on the furnace, it may light and cycle through properly a few times before failing again. I noticed this happening after I ran out of gas in one tank and switched to the other. That may just be coincidence since it had no effect on the water heater.

Has anyone experienced this or have suggestions on how to troubleshoot the issue?

Thanks in advance. -Bill
