Bonehead Furnace Winterization Mistake

[JRD]

What a bonehead move. I winterized my WH 24RKS trailer last month and somehow bumped the thermostat into the "on"position. The propane tanks have been turned off.

It's been mild here in SW Ohio and I haven't been near the TT much lately so I didn't hear the igniter clicking away until this morning, obviously trying to respond to the thermostat. I checked the thermostat switch and sure enough, it was in the heat/on position. It's off now :-/

My question: what damage to the furnace system could have occurred due to this situation?

None. Pull your battery or at least disconnect it.

[JRD]

Yes, I can see where that would have prevented the problem of the igniter clicking away.

I top off the battery then leave the trailer connected to shore power using a PT30-C EMS. I've done this for many years without incident. It might be smarter to remove the battery and put it on a battery maintainer for the winter.

Or turn the furnace off.

[JRD]

Obviously. I checked it before closing up, but it must have been bumped accidentally.

The only possible negative I can think of is wearing down the battery from the repeated ignition attempts. Like others have said, pull the battery and put it on a maintainer in a location not subject to weather extremes. I tend to keep mine in the garage.

The other problem might be wear on the sparker.. strange thing is after about 5 attempts it is supposed to give up and wait for a reset.. ( I think as the fridge does that)

you where connected to shore power, so no big deal.

my furnace will keep trying to light with the gas turned off too.

Thanks all for your replies, hope you had a Happy Thanksgiving!
