Intertherm Furnace Will not stay on

I have had to hit the reset button for it to heat. Now, I have a blinking light that indicates ''Limit Circuit Open or External Load on W.'' What does this mean?

I have had several problems with this furnace. Every year it seems we have to replace a part or two.

My Coleman furnace 4322/729 model lights the pilot but won't cut in . What could be problem ? Cleared lines Complete


Gas valve not opening? Does it have the exhaust blower that pulls vacuum switch allowing burner to light?
(1) Thermostat not working? Has to complete the circuit in or gas valve to open.
(2)Can be a stuck or bad gas valve. Try tapping the side of the gas valve body while thermostat is calling for heat. Tapping,not pounding. Like lightly,yannow? don-ohio (:^)

How do I fix my electric heater


  • sounds like the sensor or bulb that tells it to start the blower is defective/ im not familiar with your unit but this seems the most logical answer most furnace will not turn the blower on right away usually 90 seconds after the ignition but will also run longer to exhume any dangerous carbon monoxide. Electricic heaters are different. What type of unit do you have

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

Is it cost effective to replace draft inducer blower on 22 year old furnace?


Depends on the cost to repair. Probably a 22 year old furnace is not very efficient also. Take every thing into consideration.
If it still works it may work for a while but you don't want a break down in the middle of winter.
