Furnace issues

[weasal]

I have a 2021 Forest River Cedar Creek 371FL 5th wheel, Just got it back from the dealer who was working on getting all the running lights working. Opened up the camper to start to get ready for the season and wanted to use the furnace to warm up the inside to clean. I an getting a warning symbol stating "living room aircon disconnected" and also a message that says "temp sensor error" Everything was working fine when i brought it to the dealer for the running lights issue and now this has started when I got it home. Any thoughts on what I may be able to check before I have to take it back to the dealer?

I can only offer you a couple of things to try. One, we always run the stovetop first to purge the air out of the propane line. Once the burner is burning fine I then turn the furnace on.

Secondly, your sail switch could be obstructed with debris. Open the furnace panel and blow it out with compressed air. Make sure you hit the sail switch.

If neither works I'd contact your service dept. that just worked on it.

Do you have the Firefly control center?
What exactly did the dealer do to repair the running lights?
