We were out camping for the past week and needed the furnace running. Good thing I fixed it before we went as it was nippy overnight.
Previously it would start, then the burner would shut down. The local RV place charged me $350.00, replacing the sail switch, but it still did not work. I should have read the manual so I could take it right back and explain why his fix was wrong.. but alas i didn't. A new PC board fixed it.
Anyway, I hear the flame shut down every few minutes then relight again. I suspect the high temp sensor is causing this, but is this normal? The fan moves plenty of air when the furnace is opened, but it seems much less when closed up and forced out the vents. The vents and tubing are all open so it must be just the turbulent air not flowing smoothly.
It warmed the coach up in a few minutes. The little cube heater could not keep up as it was 10C inside and 4C outside the next morning.
If this is normal, then I shan't worry about it!
