I have Payne furnace Model 395CAV036055 that is not firing when I turn up the thermostat. At the thermostat I hear it ‘click’ on when I turn up the temp. At the furnace I hear the initial Vent(?) fan turning on. The furnace is trying to light, I see an orange glow alternate on and off as if it is ready to start, but no heat. After about 3 minutes it shuts off. Gas is present at the furnace. Furnace just does’t light. Any ideas? Thank you!! I have an older model(10-14years old) and there are no led's or error codes.
I know there is gas at the valve(but don't know if it is getting through), could it be a bad valve?
I've tested the T-stat.
I've tapped and cleaned everything I can find, but want to make sure I don't break anything.
Should I just order a new mother board and start there?
I have tapped on the sensors(as suggested by other posts) and made sure all the wires have good connections.
The furnace has a clean filter.
What should the fire up procedure be? Blower then vent fan then glow plug then flame?
I can't figure out why the blower isn't turning on. When I switch the T-stat from Auto to ON the blower turns on for about 2 minutes then everything shuts down again.
When doing a self test run, everything did as the panel said it would.
Thanks for your help.
