Coleman 7956C856 Burner stays on, blower runs short bursts
Posted: Sat Nov 24, 2007 12:21 am
I have a Coleman gas 7956C856. The burner is staying on and the blower only kicks on for a minute and waits a long time. I took things apart and vacuumed the A frame, and cleaned the inside of the heat exchanger.
The flame on the burner seems weak. It seems like the flame is not burning with enough intensity to to heat the exchanger. It builds up heat without the blower on, once the blower is on it cools down significantly. Cool air blows from the vents. This shuts the blower off and the cycle repeats.
Do I need a new burner kit, gas valve or gas jet (fitting)?
I'm looking for some advice on what to buy or clean.
Thanks
Bill
