2019 Keystone 29rks furnace weirdness
My dw and i were camping on our wedding anniversary. As it turned out it was abnormally cold that weekend in Northern Wis.
So we turned on the furnace set the temp via on command. The 1st day normal operation like one would expect from a furnace & worked well, 2nd day weirdness happened, 3rd weirdness continued.
The furnace stopped working periodically, the fuse panel underneath the fridge was buzzing and a red light was lit, next to the fuse position for the furnace.
The fuse not blown. Wait 15-20 minutes restart the furnace via the ucommand interface, it runs for 15,20,30 minutes, then the same sequence starts over.
Called a local dealership to inquire about a mobile tech, he says there are none and they are swamped in the shop.
The guy on the phone did offer some help. He asked some things and said that most likely the furnace was overheating and shutting itself off. He asked that i check the exhaust outlet for obstructions, I informed him that i had a insect screen coverin the intake/exhaust port. He requested that i remove it and re-try the furnace. I did remove the screen and that appeared to help with the duration that the furnace would run but it would still shut itself off.
I could see no other "junk" in the either the exhaust or intake with a flashlight.
So with this info what do i do now to correct the problem. There is no access to the furnace from the outside of the camper, only from under the refrigerator. Can i take out the grill and put a fan on the chassis ? of coarse why should i have to do that..
both propane tanks were filled day before and ther was no air in the system. Both Stove/oven and fridge running with no issues.
anyone experience anything like this before?
Sorry for the long winded post, kinda scratching my head here.
