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?

SOURCE: weak flame in intertherm furnace

Ok, so we can rule out the ignitor. (standing pilot systems can develop problems that will cause such symptoms.)

Check the gas pressure, make sure you are getting 11 to 14 PSI.

You need that after the regulator all the way to the manifold.

Also check for cracks in the heat exchanger, causing the wind from the blower to distort the flame pattern enough to cause improper contact with the flame sensor.

Make sure the burners and flame channels are clean of rust, and dibri build up, allowing the flame to properly contact the sensors.

SOURCE: 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.

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 model m3rl060abw blower makes high pitched whine when running. why? how can i fix it?


not familiar with that specific model, but if it's high pitched, it is likely the induced air blower causing it. sometimes it is possible to disassemble the motor and clean and lubricate it, but the repair that most service personell will do is to replace the motor. often it comes as an assembly which includes the motor and fan.it's the easiest, longest lasting, and quickest solution.
it is possible that it is the circulating blower with a seized bearing causing the whine. if so, the bearings (and shaft) can be replaced.

My furnace heats up and then shuts down not kicking on blower


Your furnace is shutting off on the high limit switch because of this. You are having a problem with the blower motor. You need to check for power from the wires on the board that feeds the motor. If you have voltage, and your run capacitor is good, you have a faulty blower motor. If its a fan relay, the fan would start and run all of the time. Check power to motor right after furnace shuts the burners off.

The heater fan on my 98 chevy silverado stopped working... worked on high at first but made a high pitched noise and stopped all together


Run 12V directly to the motor and see if it will run, if it dosent than the motor is bad, if it does than the resister is bad, the resister makes the blower run and also regulates the speeds for the blower, but chanses are if it was making a high pitch squeel before it quit the motor went out.

My intertherm furnace (old model) has recently getting quite loud and clunky during its heating cycles, sound like the blower maybe??


Your blower motor has several speeds to it and by the problem you are having it sounds as though the blower motor may be going out. The motor has a slower speed for the heating cycle and since you have the noise in the heating mode I suggest having the blower motor changed as soon as possible since it could cause other problems in the heating section of the furnace( possibly burning out the high limit switches). Good Luck on your repairs hope this helped
