Propane Furnace

[wildwilly.]

Furnace stopped working on current trip. Have plenty of propane as water heater and stove still works. A/C domestic unit is working but when furnace is selected the propane does not ignite and the fan does not turn in. Checked the fuses and rebooted the system to no effect.
Any help would be appreciated.
Thanks

Are you sure you checked ALL the fuses. There's one 5A in-line.

Thanks Alex. I checked the breaker and it will not reset. That must be the problem. Very unique breaker!

Have you checked at the breaker for power coming in and out? Furnace manual have a troubleshooting section?

Interesting. I didn't realize the furnace fuse was a breaker. I assume it was the 'normal old-style' glass tube type of fuse.

WILDWILLY - Not sure which 5A fuse/breaker is used in the 2017. But it may be the very common Dometic/Atwood 35791 Hydro Flame Furnace Circuit Breaker or similar. Regardless of brand, all of them are of the re-settable heat sensitive type and slow blow style - designed to protect the blower motor. And due to their location on the furnace, the heat of furnace cannot affect their operation. Also, short amperage spikes will not cause a trip. The motor has to have been producing an excessive and prolonged amperage draw to trip it. So some issue still exists. Unless the breaker itself could be bad??
