2018 Jayco SLX 195RB Furnace Issues

[jduty44]

Hi,

I have a 2018 Jayco SLX 195RB and we are experiencing the heat issues as it was used for the first time last weekend. It worked fine and ran and seemed to heat up to the temp I set it at(70deg). We then shut everything down and went fishing. When we came back that evening it wouldn't come back on at all. I also tried using the hot water heater for the first time. The pilot lights and stays lit but no blower. The thermostat/furnace will turn on once I reset the switch but either kicks the switch back to off or it will kick on and off every so many seconds. The stove lights and runs steady(both burners) I have removed the sail switch to look at it and it was nice and shiny with no debris or anything on it. Any ideas on something like this. We bought this from Camper World here in Greenwood, IN and have had nothing but problems with them. This is a dometic furnace. I appreciate any help and thank you- Id really like to not go back to Camper world...

Had a lot of rain lately?

Well not so much, but what would that cause just so I can understand if it is the issue?

Have you checked the voltage of your battery ( unless plugged in)? If the voltage drops to low than furnace board will have fits. Also, my water heater does not have a blower.

Post the exact brand and model of your furnace, water heater or any thing else you have a problem with as Jayco changes models and brands almost daily.

Double check outside that your furnace inlet is not blocked by wasp nests, etc.
Check if you have them the batteries on your thermostat. Most who use the furnace replace with simple digital ones that work much better to keep temps normal.
Several youtubes out there if you have wifi that discuss furnace issues, worth watching a couple.

The outside cover can leak water on to the control board. Causes crazy stuff to happen such as going through the 3 lighting cycles and cutting off.
