Furnace not working.

[Rickl111]

Hello all,

This is my first post on here. I will try my best to relay everything I know.
I bought my first trailer back in August. Since then there has only been one night that the heat was needed. Tonight it’s getting down into the 30s and it still isn’t working.

The trailer is a 2019 wildwood 31kqbts. It has a Suburban SF-25FQ. At first I would turn on the thermostat and all I would get is a click sound coming from the air conditioner unit. I removed the furnace and found out that they had the blower switch turned off.

I tried to cycle it like the manual says to do, but still no heat. The blower comes on and I can hear clicking a few times but no heat. I turned on the oven to make sure that propane was flowing. I also cleaned out the furnace like instructed in the manual. Nothing blocking anything in there all I found was a live frog that I took out.

The furnace has a gas valve on it model# 161122. There is a screw on the valve that is turned all the way to the right. I’m not sure if this is a manual cut off or not. I tried googling and there isn’t any information on it.

I looked in the library area and didn’t find an answer to satisfy my problem. Any suggestions are appreciated. Like I said I’m a first timer here it could just be operator error.

I am assuming the thermostat is set to heat and you have the fan on auto? You have already checked a few obvious things. Im sure other more knowledgeable will chime in with more specifics with control board/ ignitor fixes.

Yes set on heat and fan is on automatic.

So the furnace has never worked?

It could be a bad gas valve or a kinked gas line. Have you checked to make sure you're getting 12 volts to the valve solenoids when it's trying to fire?

This is good advice. Especially if the furnace is in a slide. There have been lots of reports of ovens, stoves and furnaces not working because the line was kinking as the slide moved. Happens in stationary positions as well.

These furnaces are not really complicated and the service manual has a real good troubleshooting guide. If you don't have the manual, they are available online.
