My Coleman Evcon furnace Model EB 12B will start out blowing warm air and then before it reaches the temp set on thermostat starts blowing cold air. We had the thermostat changed over the summer and the...


look at the furnace and turn it on to see if the flames come on. Watch and see if they stay on for a period of time. If they come on then go out you may have a dirty flame sensor, if it goes out and then relights it may be a high limit switch getting weak. hope this helps.

This is a colemon evcon electric furnace for mobile home the blower work fine just won't put out no more heat any ideals


when the fan is operating, is the fan switch on the thermostat in "on" or "auto" position? if it\'s in the \'auto\' position, then the stat is calling for heat ok. if so, you should check the safety controls for closure...i.e., the rollout switches (if there are any) and the high limit control, you should also measure the voltage at the gas valve. if you have 22 -27 volts at the gas valve, and you have all upstream gas open, and you have gas available (not shut off by gas company), but still no fire, then you probably have a defective gas valve. otherwise, if you have a wiring diagram, it should be easy to find the problem.

My coleman evcon fan motor does not come on. I put the thermostat to on so the fan would run but it will not come on. The rest of the furnace runs properly.


Did you check to see if you have power or fuse blown? If it is a furnace/ air handler and you are comfortable with electricity. Turn
Power off, remove blower door. Find where thermostat wires come into the control board and remove them. If you can find a jumper wire or aligator clips, hook them between R and G. Put blower
door back on and turn on power,

Fan should come on right away, if it does you might have a thermostat problem. If nothing happens but you can hear it hum
or hear nothing at all. Then more than likely the capacitor is bad and or the motor is bad.

I have a Goodman A/C unit model # GSC130361F A and a Evcon


The indoor fan should cycle with the outdoor part, make sure the thermostat is not set to fan "ON" and if the fan is on "AUTO" it could be a wiring issue or a fan relay that is stuck.

Air conditioning runs all the time


I assume this is a manufactured home, this is probably a two transformer system, either your contactor is welded in the on positon or wyou have control wiring issues, (could be the thermostat)
