SOURCE: Coleman presidential II furnace blower on and off

Sounds like the flame sensor. But it could be the thermostat. Is the furnace standing pilot or electronic spark or hot surface ignition. I would start by checking thermostat. Turn power off to furnace take thermostat off wall and take wires marked r & w and connect them together. Turn power back on if furnace works then change out thermostat.Most eclectronic ignition Furnaces have a flam sensor, You could take flame sensor out and clean it up with steel wool or wire brush. If you need anymore help just reply back .

Is this furnace standing pilot or electronic ignition. If standing pilot i would check furnace filter then the thermastat. To test themostat first turn power off to furnace. Take thermostat off wall and take wires labled R & W and connect them together. If you have electronic ignition I would start with cleaning the flame sensor with steel wool or wire brush.If you have and more questions i will be glad to help.

Go to www.grainger.com and look for a "power pile generator" this is a millivolt thermocouple that may be just what you need to make your heater work again

I have a coleman furnace it comes on the electric igniter glows red the gas comes on then the blower starts and the fire goes out it gives 2 different code for this 1 is ignition failure and the other is...


I would have the ignition control board replaced. That is what tells the gas valve to come on and if there is flame or ignition it will keep the gas on if the flame sensor gives the board a signal that the burner is lite. By you shuting power off and on to the furnace it resets the board and it will go through its cycle again.

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

Gas furnace; flame will not stay on


Clean the flame sensor with a green scotch brite pad. Check all ground connections from the circuit board to the furnace cabinet. Check for a proper ground to the electrical box. Make sure polarity has not been reversed.

Coleman furnace -- fan runs, ingniter won't light,


Hi,
The chances are that the furnace was running when the power went out. This will cause the high limit switch to cutout and needs to be manually reset.
You will find that switch in the blower compartment near the blower. Usually somewher near the highest point of the cabinet.
Push the little red button firmly till it clicks.
When the power goes out while the furnace is running the heat builds up because the blower shuts down immediately and causes this limit switch to cut out.
If you have a electric tester you can also follow the low voltage circuit till you find the open switch. Ther is usually a wiring schematic on the door cover of most furnaces.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

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.
