Furnace pilot out

[noahrexion]

Heater was working great about the last week. I can only think the auto pilot is not working as the fan still runs and I've plenty of propane.

Anyone replace the pilot? Is it accessible through the inside cover? John, any insight?

I couldn't find anywhere to access this pilot.

What furnace model is it?

On mine, the blower kicks on, and a few seconds later, the igniter lights the furnace, mine has no "pilot light".

A common problem is the sail switch, this switch tells the controller that the blower is running. If it doesn't detect the blower the furnace doesn't light.

If I remember right, it only does one try, if it fails, it doesn't try again or reset, and the blower runs forever.

Download the manual for the furnace and look at the sail switch.

Unless it's very old like Waiter said it's electronic no pilot. Try it with the MH plugged in and see what happens needs pretty good air flow to trigger the sail switch so if your battery is a bit low it may not light. And yes if it's the original board it will only try once you'll have to turn it off let the fan stop and try again.

You were both correct, for the record!

I hadn't, at that point, checked my coach voltage for about a week. Indeed I had about 60% or so charge and once plugged in/charged back to 80%+ the furnace is working as it should. Just wanted to follow up for reference.
