Question about Coleman Propane Forced Air Heater w/Electronic Ignition (50,000-80,000 BTU)

1 Answer

I have a Coleman furnace, model # 7995-656, in a mobile home and the blower is short cycling. It will run through it's cycle, shutdown for a minute, and then just the blower will kick on again for 30 seconds, shutdown for a couple of minutes, and then kick on again for 30 seconds and shutdown again. It has new filters, and a new t stat. What do I need to check, or replace? Thanks

This is caused by the 'fan switch'. It normally holds the fan blower off until the heat builds up a bit, then it starts the blower. If the blower begins cycling, change the fan switch. It's located right on the side of the duct inside the furnace with the cover off.

This is what it looks like:

I wish I was a furnace expert but I will give a push in the right direction. When a gas/electric fan runs it has two speeds. When you turn on the FAN ON switch it should run at the slower speed. If it doesn't turn on or turn off again when you turn it back you have a wiring problem or a thermostat problem. Make sure the thermostat is compatible with your unit and wired properly (on both ends). The other time the fan runs is "in session" when heat or cooling is applied to the system. It should run until the system finishes the cycle then a bit more (30 seconds or 1 minute) to blow the treated air completely through the ducts. If it doesn't stop then you may have a bad fan time delay or relay. Check parts for your model and various appliance repair site online.

If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Coleman Presidential II mobile home furnace. When burner lights the blower cycles on and off instead of blowing constant through burner cycle.


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.

Heater blower motor cycles on and off (frequently). I have a class 2 LR95329 Honeywell Thermostat


The clicking noise is a relay or switch of some sort. You are right about that. I have 2 questions. 1) does the thermostat have a mercury bulb in it? 2) when the fan shuts off and on, does the burner stay on?
