furnace quit working
Out camping tonight. After getting set up, furnace ran great. Had no problem last time out either. Now nothing. Noticed gas selector switch wasn't all the over on the front of trailer, only half way. Furnace ran fine for 3 hours, and cooked dinner on grill that way. Turned it all the way over to that tank, both tanks are new and full.
Blower comes on, but wont lite. Tried to purge line of possible air by running grill (ties in to gas line right after furnace line), also ran the range (last thing in gas line. Still nothing. Cycled the furnace about 20-30 times, giving 5 minute brakes some times.
Tried turning all power off by unplugging to electric and disconnecting battery. Let sit for 5-8 minutes thinking their may be a reset. Still no flame. Wife and daughter got cold, I gave up and we drove home at 130am. Any ideas?
I didn't take burner access door off, but didn't see anthing in burner observation window.
If I'm not getting a spark, do I need to replace electrode. Don't know if I'm getting a spark or not, just thinking out loud.
Worked fine last time out, was working fine for 3 hours. Then nothing. Any help would be greatly apprieciated.
