Question about Heating & Cooling

Open Question

I have a Lennox Elite Furnace G50UH(X) The Blower that circulates air throughout the house doesn't come on. There is a whining sound the top part of the furnace fires then gives a

Switching to "fan" mode on the thermostat results in the same whining sound. Top of furnace starts up lights for a while and shuts down as I think it should with no air circulation. I get RF interference of the same pitch on some audio devices around the house - I could be imaging this one because it is not explosively loud and persists after I switch it off. The repair guys made it sound like removing the motor is really difficult but others say its two screws and it slides out. How does it come out? Also some say a bad motor spins freely. My fan turns by hand with a steady heavy dragging friction. Kind of figured a good motor would give a magnetic field feeling in the friction not a constant drag. Is the motor bad? I've heard that you can test the motor by powering it from the cover door shut off breaker but haven't tried that yet. Guess that would be my next step. Any advice would be appreciated.

SOURCE: 6 blinks

sounds to me like i wish i could find out if this is new install or if the electric has been changed recently,,,sounds like reversed polarity on the plug,,,which means the white and black wires need to be swapped. If there has not been change recently than u need to see the other post i made on goodman about the combustion fan motors and there types and fixes. But almost certain that is reversed polarity. good luck

SOURCE: no power to ac indoor fan motor

sounds like you might have a bad control board. try putting a jumper wire on the control board low voltage terminals R and G your fan should come on and run if you have 120v power to fan motor. double check that you do have 120 leaving board and going to motor. if no 120 bad board if you do have 120 bad motor. if it is the board it likely has a bad blower relay which is common in amana models and goodman equipment.

SOURCE: Induced Draft Blower Not Blowing- 3 Blinks on LED

Your doing well just right. When the call for heat is on the draft motor gets a call from the board to come on. When this happens if no voltage is present at the motor then you ahve abad baord. Replace it.

Coleman Evcon furnace. Can i make it circulate air?


Your thermostat should have a "continuous blower" setting. Use that instead of fooling around with the A/C setting

My Goodman Furnace Model GMS9 circulator blower makes rumbling noise. It sounds like something is not inline and I can feel it even when i'm sitting upstair too.


It sounds like bad bearings inside the motor, or an off balance blower wheel. When you say circulating blower are you talking about the main blower, or the IDM (smaller motor in the top cabinet)??

Furnace computer won't let furnace light


What is the model number? I have an SLP98 (installed on 11/29/2011).... and if I take the cover off the front of the furnace the panel that has the fancy "Lennox" badge on it) you will see two clear round windows about the size of a half dollar (one high on the furnace box and one lower on the blower box.) If you look downward into the window on the blower box you can see a red LED display that will sometimes flash error codes like E228 (one character at a time). If your model has something like this, let me know. I've done some DIY fixes recently out of necessity....and their easy.....and several technicians confessed they didn't know much, if anything, about the newer high effieciency Lennox gas furnaces.

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.

Why is it whining and humming?


Sometimes a louver on the squirrel cage comes loose maybe from taking it apart...hand test every louver. You may find that you need a new one.

The bearings are bad. You need to replace the motor. Motor cost $75 to $125. Labor is on avg. $150 to $400 with an decent A/C Company . You can try to oil it but its not recommend by Lennox. That furnace at the time they build it was top of the line. Good Luck.
