Rmove the two screws holding the blower in place and slide it out. With the power off, rotate the wheel and inspect for debris or an impingement. If everything turns easy, you have a bad motor or start capacitor. If you have rubbing, adjust the wheel. If the motor will not turn, replace it.

I am a furnace technician and to solve the problem.You will find on the opposite side of the ignitor their is a flame rod with a wire connected to it.Remove it and clean it with sandpaper and re install it and it should fix the problem.If this is dirty it won't sense ignition and the board thinks that is it introducing raw gas into furnace and it isn't igniting and shuts off as a safety precaution.If you see a blueish tinge on the flame rod you should probably replace it.

SOURCE: furnace clicks multipal times while running.Is this normal?

As it starts and stops several switches will open and/or close, sometimes you can hear them. When it's just running then it may make a few noises from expansion and/or contraction.

I have a Coleman Natual gas forced air Model 7970C856 The poilet light stays on but furance burner does not kick on. What could it be?


Hello, this could be a problem with the thermocouple or gas valve. Start by replacing the thermocouple since it is very inexpensive, if that does not get it going sounds like the gas valve will need to be replaced

I JUST BOUGHT A USED COLEMAN EVCON FURNACE MODEL #BGU09516 AND I NEED TO KNOW HOW TO VENT IT. PLEASE HELP, THANKS


It should have a two part chimmney with a 4 inch inner exhaust section and a larger 6 inch outer section that goes over the flange on the top of the furnace. If your existing chimmney does not have this you may have to buy a chimmney kit for a mobile home application.

Small blower motor? Are you talking about the combustion blower if so then check your vents for blockage.. if the vents are blocked won't work... if it has a control board init it will give you a diagnostic code. Flashing light on the board... count the flashes and look up the fault on the chart in your owners manual ot on the furnace door..
