Furnace out

**Sparkydh** · 11-12-2020, 03:43 AM

I just can’t win. It got down to around 30 last night and now nothing from the furnace. I can hear the relay in the ac unit in the bedroom click so I know the thermostat is working but no blower or anything. Fuse is good. Any thoughts? It’s been working fine but not now. 🙁

I wanted to add a question. Is the relay I’m hearing clicking in the ac unit the time delay relay? If so, it sounds like I need to start there and work my way to the motor.

Easy stuff first: Adequate 12V power and LP tanks not empty?

Yes to both. I’m not getting the blower to even come on. I need to check for power at the relay and the motor.

It could be a fuse that blew as well so I would check that also. Start by disconnecting and connecting the electrical connections at the furnace. I get a bit of corrosion on my fridge board connections which prevents the fridge from running on gas. I remove and reconnect and all works fine for a while.

I checked the fuse inside. I’m trying to go with the simple stuff first. I’ll check the connections.
Thanks.

The furnace should have nothing to do with the AC unit.

Thermostat power comes from the furnace and goes to the AC.

Got heat. There was some corrosion on a few terminals. I found the sail switch was intermittent so I got a new one on Amazon. Put it back together and all is fine now.

Just bought 2019 Reflection 337. On initial inspection, furnace worked. Now nothing. Checked the fuse on the main fuse panel; it is ok. Not sure where to go from here.

Jeff, what is a sail switch?
