I have a coleman furnise in a 2002 mobile home. Model DGAA056BDTA. Heating and air conditioning works good. The only way the combustion motor will shut off is with the breaker. I had to replace the motor because a bearing went out, and in the process I found a circuit board on the roof with the motor. I don't know where else to go with this. Please help. Thanks.

I'd have to find a manual. Causes of this kind are usually traced to relays that the contacts have fused. They may be on the control board or external. You may need to replace the control board.

Go to this site and post your problem under coleman. This is a great mobile home site and they have parts also if needed.
