Hey guys thanks for reading.... Just bought a new pop up camper 1999 Camplite and it is awesome. I have been a camper for quite some time, but this is the first pop-up I've ever owned. Kids love it!!!
Okay, furnace seems to have a problem and I need a little help. Don't have a huge budget so I don't want to take it in to get serviced, but I am very mechanical and can replace or repair things if I have a little assistance. Here's my problem...
I have two propane tanks 100% completly full. Also have a good 12 volt battery hooked up to a 6 amp battery charger full time so I know I have about 12-14 volts. Furnace only runs off of the battery. I can have 110volts plugged in and the furnace does nothing without the battery. I also switch the tanks from one side to the other and get the same results.
When it is cold outside the furnace will turn on okay. Kinda has a little bit of a poof when it lights, but it does light. Scares me just a little bit cause it pops when it lights (sometimes). After that furnace runs great and heats up the camper. No soot, black smoke, or weird smells. Problem is when the temperature gets to where it needs to be the gas shuts off. Which is normal, but the furnace fan needs to run a little while longer to cool the parts inside which is exactly what it is supposed to do. Problem is it never shuts off and just keeps blowing and blowing. 30 minutes later it is still blowing very cold air. So I shut off the theromstat and turn it back on again and it turn on heats up the camper great and the gas turns off and the fan doesn't stop running and does the same thing over and over again.
I am guessing that I have a bad sensor or switch. I figure it is something pretty easy.
Furnace is an Atwood hydro flame. It has an automatic pilot light. The label is missing, but I have an owners manual for a 7900-II, 8000-II, 8500-II, 8500-IV, and 8900-III. So I am guessing that it is one of those models. It has a light brown cover that you need to push down on to remove the front.
Thanks a ton,
