Furnace Issues
Our 2007 34' trailer is my stepdaughters "space". The furnace had been functioning flawlessly up until a week ago. When we slid the vertical temp set slide we heard a metallic click (propane safety valve?) but no fan or anything else. I pulled the cover off the furnace and checked for continuity and voltage at the limit switch. We continuity across the switch and 13.6 volts on both sides. I ordered a new control board and sail switch. When the board arrived I installed it, the sail switch has not arrived yet. With the new board installed and everything put back together I slowly cracked the valve on a fresh 30 pound tank of propane, then checked for gas at the cook top, good gas flow. Went to the Coleman Mach t-stat and set it to "heat" slid the temp set slider way up and nothing, not even the safety valve click and no voltage at the limit switch. The safety valve is up stream of the limit switch and had been working fine. I can't get the darned cover off the t-stat to check for voltage so far. Does anyone have any insights?
