SOURCE: furnace fan running off and on blowing cold air

Need a little more info. Does the fan never stop? Is this a gas furnace? Is your thermostat in the fan auto not fan on position?

Check fuses. one may be blown, and the other one not, Therefore you are getting only 110V to a 220v circuit.

SOURCE: Clunk noise Ruud Furnace

I had the same problem, the motor shaft and bearings were going bad. There was about 3/16" travel on the shaft that the blower attaches to. I replaced the motor myself and it runs nice and quiet. I have had that noise that you describe for over 8 years, but it got real noisy about a week ago. I talked to the maintance department about it where I work and they said the motor bearings were probably going bad. They were right, I took the motor out of the furnace and they took it to a parts store and got me a new one $270.00 for it. It is a special motor due to the fact that the frame mounts bolt directly onto the motor housing. Make sure if you do this job yourself that you take the motor to the parts store so that they can match it up. The guy at the store told our maintance man if it didn't require the bolt holes in the motor housing it would have been $100.00 cheaper.

It sounds like you have a possible hole in the heat exchanger. Turn the heat off and turn the fan on. If you feel any air coming back out of the heat exchanger, you have a hole. A yellow flame is not a good sign. I would even consider having a service professional come out and take a look.

Sounds to me like it is going off on a weak high limit switch. With the fan on it will prolong the event but will not stop it. I would check all of the high limit switches. It would most likely be one close to the heat exchanger.

Intertherm furnace/AC, fan on the furnace won't shut off.


How old is the intertherm. The old ones have fan limit switch and sometimes they stick. The new ones have a fan baord or time delay relay. They go bad from moisture and they just go bad sometimes. It sounds like you just have a shorted relay. If you think you can replace it you can get a relay at any parts store. Need the model number of unit. If not just call a service tech for free estimate.

Furnace won't stay on


Flame sensor could be dirty. It is located right beside the last burner looks like a thick piece of wire. Take steel wool and gently clean the probe 4 or 5 strokes is all it will take to take off the carbon build up off. Lets eliminate this item and see if it clears up okay. ken
