It could be a thermostat problem. Also it will seem to run constantly as it tries to heat and one of the elements are working which could be a sequencer problem.

SOURCE: Coleman furnace blower runs continuously

You should be seeing 120 volts to the igniter. Anything less requires either a replacement of the transformer, start relay or control module.

SOURCE: Coleman Evcon furnace, blower runs

make sure the thermostat is in the auto mode if so it is more than likely the fan relay control some are built on the board some can be replaced separately

SOURCE: furnace blower not working how it should

first off buy yourself a honeywell stat, in my personal opinion lux stats are garbage, I have run into so many that are bad stats !!! but as far as your fan not shuting down, sounds to me like your fan center on your circuit board is bad and will not shut down the fan when needed, you will have to replace the circuit board, as the fan center is a part of the whole of the circuit board, hope that helps

SOURCE: i have a coleman/evcon electric

Have you tried to replace pressure switch for the combustion air. If your not sure where to find it if you pull the front panels off follow the flue pipe down to combustion chamber the combustion fan motor is either inside the flue pipe or out side of it not sure on the one you have but you should see two plastic tubes that connect to a barb onto the topside of the fan and one on the bottom they both should go back to the pressure switch. i hope this helps you if you have any more question or if this doesnt fix the problem just reply back to this message . Make sure fan is working when furnace starts up. It should be the first thing that comes on when there is a call for heat

SOURCE: coleman echelon 9.T furnace will not turn on. Red light blinking

sounds like it is the pressure switch try jumping it out on some models you fool the heater in too working or see if the tubes are blocked , there should be some codes on the front panel or the fan panel

Coleman Evcon furnace blower runs w/ no call for heat. Temp is 5+ degrees above thermostat setting. (Programmable tstat)


When you say door are you referring to the front door or the furnace door? If the unit kicks on AND off by itself I would say it's in the tstat or the tstat wire. If it were internal I would think the blower relay or heat contactor/relay were getting stuck AND THE FAN WOULD NOT TURN OFF until you flipped the breaker. Good luck

I have a Coleman evcon gas furnace that the blower comes on for no reason . Does not do this all the time . It comes on and runs for about 3 minutes and shuts off . Does this 4 or 5 times in a row .


James, If it has a electronic board, it has a heat sensor built into furnace that turns fan on to get all the heat out of furnace for efficiency. May need adjusted a bit, or replaced.

I have a coleman evcon electric furnace. The blower fan runs constantly, the switch is in auto and the fans runs even when the thermostat is shut off.


Most likely on that particular electric furnace you have a fan sequencer that is closed (stuck shut). It is the black relay that you are looking at when you take off the furnace cover to access your heat strips. You should have a red wire coming from the blower motor that plugs into the side of it. If you have a ohm meter turn power off and remove wire. Check resistance across the sequencer and it should read OL. If you have resistance across it, the relay is bad. Replace it.

Coleman evcon furnace


How old is your furnace? Does it have a circuit board that controls everything, or are there separate controls for each function?

I have a coleman evcon electric furnace ,it was running and would not cutoff the heat got up to around 90 thhe thermostad said it was running in aux ,so I turn the main breaker off and the in a few minute...


If the thermostat is ok which it probably is then your sequencer is most likely stuck i would say. You could verify that by removing 24 volts to the sequencer to see if it will shut down the heater
themobilian_598.jpg When low voltage from the thermostat is applied at the base of this sequencer it heats a bi-metal and turns on each coil and fan in a sequence that will insure the breaker don't throw from the power surge AND warm air comes out the vents when that fan comes on. I would start there.

I have a Coleman Evcon gas (propane) furnace. When the t-stat is switched to heat the furnace heats up but the blower will never turn on. The unit then shuts down and tries to cycle again. I have replaced...


If the unit fires but the main blower fan doesn't come on the the unit is shutting off on a temp high limit switch and it sounds like the problem is the main blower fan motor or control

My furnance is acting up you turn it on it clicks on then lights the flame gets big then seconds later the flames go out and the blower kicks on what could be the problem ive had several people look at it...


If the fan takes too long to come on, the high temp limit may be opening. Could be a defective limit, hard to say without more info. Another possibility is a mis-adjusted heat anticipator. A normal setting would be around .45 amp. The heat anticipator is inside the cover of the thermostat (older, analog style). Good luck.
