I have a Coleman Presidential II unit in my mobile home that is natural gas. I just recently replaced the blower wheel. The heat worked and when I switched over to the Ac the transformer started smoking. Naturally I turned off the unit quickly as possible. My problem now is the blower only comes on when it is switched to continous. I do not have heat or ac. Any idea what the problem could be? I was looking for a fuse but didnt see one. The only other thing I can think of is the transformer is bad or the limit switches are bad. Any help would be appreiciated

control circuit
you are going to have to troubleshoot the unit to see what is presenting a direct short to the transformer secondary. could be a switch. I doubt it would be a motor. it could be a relay coil that is burnt up or shorted. -
The motor is good. What would I check for a short and what should the voltage beComment

Has anyone had an occurrence of a Laser 730 or 731 over firing?
The top of the heat chamber and the heat exchanger glow red on high when this occurs....
