furnace

[Todd757]

2008 Fleetwood Discovery. Last used our furnace in April. Worked just fine. Turned it on this past weekend, nothing happened. No fan, no heat. Checked breakers and fuses. Anyone have any ideas?

Thanks. Todd.

Rest fuse on furnace. It's a push button type fuse

Last one I fixed did what OB said fan came on no fire installed new circuit board and all was well
agree with OB on resettable 12V circuit breaker I never thought about it have a reset breaker on the furnace itself ?? maybe good to take a check on that

T-stat....
Select HEAT
When you move temp set point UP (higher then room temp to HEAT room up) do you hear a 'click' at the t-stat?

If yes......
Then furnace fan should come on and blow cold air for 30-90 seconds (purge cycle)then propane ignitor should fire (Click, Click, Click at furnace) and burner light off

No click at t-stat...
Feeder DC Fuse bad. It would be in the DC Dist Panel...individual fuse 7.5A minimum or a 15A fuse (test it don't just look at it)

Click at t-stat but no furnace fan
Then the On/Off Circuit Breaker on furnace frame may need reset (open furnace access panel and push button in to reset)

OR time delay relay is bad (either a stand alone component or incorporated on to circuit board ---blower power)

DC comes from feeder fuse to timed delay relay/blower power on circuit board and to t-stat.
DC power to fan goes thru relay/blower power WHEN triggered by DC from t-stat

For specifics post Brand/Model of furnace

You mean from the panels outside? Or something on the inside?

where the furnace is? If the vent is outside yes stick your ear there have your ole lady turn the stat off/on a couple time and make sure temp is set higher than current air temperature
iam just trying to make sure the stat is sending a signal your heater motor may have quit but the stat will still send a signal and there should be a click
if not pull the cover and see if the circuit board is powered up when the stat is activated using a 12V tester

The thermostat works with AC, and electric heat. I'm assuming it's working correctly.

your sure you have 12V at the furnace? when you turn the stat on or set temp "higher" than current room temp do u hear any clicks at the furnace? that should tell u if stat is sending signal or not

I assume you have a good 12V power supply and the thermosat is working?
