Replace blower motor in Lennox gas heater

I need to replace a blower motor in a Lennox gas-fired home hot-air heater. It is ''chirping'' and I want to replace it before it quits. I have located the correct replacement part, and it looks like a fairly easy fix (insert shaft of motor and hook up two wires). Is this something I should attempt myself after shutting off power to the unit?

    Thanks for your help...motor needed lubrication...the oil finally reached the trouble spot and the chirping went away.

It is a fairly simple operation. The hardest part may be seperating the blower wheel from the motor shaft. I recommend first sanding then applying a little oil to the old shaft. Prop the blower housing aprox. a foot off the floor with the motor facing down then using a wrench (NOT pliers as you may scar the shaft) hold the wheel with one hand and work the wrench on the shaft work it back and forth to loosen. DO NOT hammer on the end of the shaft as you will mushroom it ever so slightly. The weight of the motor should cause the shaft to slide down. Good luck and don't forget to answer back if this works or not.

Motor blows igniter works but will not fire


The motor you are hearing may just be the inducer motor, this is the one that creates suction in the system before the gas is released/ignighted. If the system turns on, and you can see a flame, and the gas ignites, but then the system shuts off, this is your blower motor not firing up. Check the leads that go to your blower motor, the bigger one that pushes the heated air to the entire house, if they are getting power then you may need to replace the actual motor itself.

I have a Lennox 80MGF3/4-100A-1 forced air gas heater and the pilot light isn't lighting automatically as it is supposed to. Can I light it manually?


NO, they are not like the old ones that sometimes you had to relight on a windy night.. there is not a gas pressure control lever and too many safety switches will keep things from happening. and the induced draft blower motor would be like starting a fire in a wind tunnel. even if lit. it would extinguish it's self at the end of the heat cycle and put you right back with no flame. i miss old tech!! so easy to fix. and keep it going. are the heating wires getting red hot! those hot wires are what ignite the fast flowing gas.

The circulating fan on a Lennox GR6-25/30B-WH Warm air Heating system fails to run, whilst the burner fires up as normal, any ideas please?


The most common causes are:
1: Failed Blower Motor : This could be an electrical problem (windings or failed capacitor) or a bearing problem. If you wish to take this task on yourself, you can take the entire blower assembly to include the capacitor (if applicable) to your local HVAC parts house or contractor and ask them to check the capacitor and/or motor. They can match the motor for you if needed. Note: you should always replace the capacitor whenever replacing a motor.
3: Failed Fan/Simit Switch: this switch senses the temperature in the heating chamber and will energize the motor once the temperature reaches it's set point. If the temperature continues to rise past the LIMIT setpoint, the switch will de-energize the gas valve to prevent damage to the heat exchanger. Here is a video to help you:

I am looking for an installation manual for Model FUBSK blower motor kit. We bought a new home and the Lennox Superior wood burning fireplace Model BC-36 has a switch that should force heat out into the...


The fan should be installed behind the bottom grill, and then it should blow air around the firebox which then exits out the top grill. Now saying that, let me explain the actual problem you will face. Because you have a open faced wood fireplace, you will not get the heat your looking for, the fire needs 400 cubic feet of air per hour and that air is taken from your opening. Also the inner box doesn't heat up enuff to produce alot of heat on the skin so if you have the fan blowing full blast, it will only cycle the air and not allow it time to heat up as it cycles around the box. I suggest turning the fan speed down so its 1/2 way on or lower, this allows the air time to heat while cycling around the box, but in the end you still won't have a good heater as the fireplace itself isn't one, you should look at having it converted to direct vent gas or ripping it out and replacing it with a airtight wood.

Heater is not working on my 2003 dodge caravan


Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

Hot air blower does not opperates


assuming this is a central heater, it could be the motor or the control circuit from the board shutting it off. The motor needs to be checked for voltage when calling for operation, voltage w/ no operation= replace motor and capacitor
no volatgage means replace component that controls motor
