Furnace Problem

We recently moved from Phoenix to Salt Lake City and used our furnace for the first time in a while. It worked fine the first night, but the next night we set the thermostat before we went to bed and the furnace never came on... believe me... it was cold enough! I checked the fuses and they were fine. I reset the furnace fuse and turned on the furnace (at the thermostat) and it came on for about 20 seconds, then died. I turned it off. A litle later I turned it on again and it seemed to work fine.

Could this be an aberration, or might I have a more serious problem?

May have had air in the line and needed to purge. After 5 or so attempts to light, many lock out and need to be reset. I always run my stove burners for for a bit to purge as much of the gas line as possible.

I too had this happen. Furnace working fine and the next morning nothing! Checked all fuses,thermostat, gas at the stove and fridge. Called a mobile RV repair and they said they would not be out until that evening. After 15-20 attempts at starting the furnace thru out the day it decided to work. I called the repair man and told him the furnace is now working and his reply was to clean and tighten every connection to the furnace and after standing on my head for awhile trying to figure out how to get into the furnace I am going to see if I can get my hands on a manual so as to have a clue of what to do. I have read other posts to this issue but haven't read about a fix. When mine acted up It would not attempt to start and you stated that yours had for 20 seconds. Hope to hear from others on the forum on a solution.

Looking at the trouble shooting guide I think I may have a faulty temperature switch in the fan motor as mine will cycle on and off every few minutes.

I recently had a similar problem. Trouble shot it for a couple of hours.

You may want to check the gauge on the propane tank. It is possible that the gauge in the coach is worthless and the stove-top pretends to work despite there not being enough propane in the tank to run the furnace.

I'm not say'n this happened. I'm just say'n that in theory it is possible that the tank could have ever-so-slightly less propane in it than you thought...

Propane pressure can be significantly affected by cold temps.
