    Its belt driven, two wire motor. This is an old furnace wich has been surviced with refurbished parts. There is no label on the motor, no rpm, volt, amps, hp. I will check the voltage and get back to you. Btw am an electronic technologist and I can follow your requests.

    Thank you

  • gaandre Sep 27, 2009

    I forgot, the motor has no capacitor mounted on its frame.

  • gaandre Sep 27, 2009

    Voltage at the motor and running is 19.5V ac rms.

  • gaandre Sep 28, 2009

    I regularly oil the motor, change air filters, etc. I have remove the motor and the shaft easily turn, the bearings feel normal, therefore it would have to be the windings. As I have said before, this furnace has on and off been serviced by annual contract and they use a lot of old refurbished parts. The motor has no label, no volt, amp, rpm, h/p, . The rpm worries me, how can I purchase a new motor without knowing its rpm and h/p. If I bring the motor to a specialized shop, will they be able to tell the specs. of the motor?

  • gaandre Sep 29, 2009

    Yes, I was stuck in a loop. It had all the symtom of a defective capacitor for the motor but I could not find one on its frame. I taught maybe its mounted in the Honeywell controler. You got me out of that loop and started looking at a defective motor.

    Thank you

The motor bearings are worn and/or the motor windings are bad. Check to see if the motor has any tubes or caps at the bearings to add oil. You may need to remove the motor and dis-assemble it to oil the bearings. If it has sealed bearings you will not be able to oil them and will need a shop to re-build the motor or buy a new one. The buzz is from the motor binding and will overheat the motor & possibly damage it if it has not already. You could try using 3 in 1 oil and apply it to the motor shaft. It may pull some of the oil into the bearings and help a little. But if the windings are worn out the motor will need to be re-built or replaced. Also make sure that the belt is not too tight...this can cause bearing failure in a motor. Let me know if you have any questions.

  • Anonymous Sep 28, 2009

    If the motor is original you might get lucky. The older motors have oil filled bushings that can be re-oiled to get them working again. And being a 20V motor means that it probably does not draw too many amps. A low voltage motor like that can be slowed down very easily by some extra resistence.

  • Anonymous Sep 28, 2009

    The motor shop can help you with that. They should be able to re-build that one are get you a new one. By looking at the motor they can guide you to the correct replacement.

Maytag gas dryer Model MDG8426AGW. Cold dryer starts fine. After 60 minutes clothes still a little damp. It needs more time to dry. When I push the start button the dryer buzzes but will not start.
Could be something not letting the motor turn freely. Like lint jammed against the fan , tub bearing bad or needs grease . if the motor will turn freely by hand it could be a bad motor.winding .you could take the drum belt off the motor & see if the motor will run ok If it buzzes with the belt off pretty sure the motor is bad you would have to replace it . A motor is expensive so try to check everything to be sure it is bad. I have seen some that you could oil the motor shaft & it would help. If lint is keeping the motor from turning clean all the lint you can all through the dryer & the outside vent .If you check the motor with the belt off don't run it very long as it will get too hot . Hope this helps

WHEN PRESSING START UNIT JUST HUMS
If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor:Remove the belt. Check for obstructions in the blower fan housing. Manually rotate the shaft of the motor.If the motor is very stiff, or impossible to rotate manually, and the blower fan housing is clear, you need to replace the motor. If the motor rotates freely, run the motor momentarily with the belt removed and the blower in place. If the motor runs fine with the belt removed, there may be a problem with the idler pulley or the clothes drum. Try to rotate the drum by hand. If it is very difficult to move, correct any problem with the rollers or pulley, and then reassemble the dryer and try it again. If the motor hums but doesn't rotate on its own even with the belt removed--yet you can turn it freely by hand--you usually need to replace the motor or the motor start capacitor.

When we push the on button, you can hear a hum,
Sounds like the belt that turns the drum has broken. the hum sound is the motor turning. Does it still get hot in the drum? If so then you need a replacement belt ($15-$25).You can open the rear or the dryer to confirm the belt is broken. Be sure to unplug from the wall outlet to avoid electrical shock.

THE DRYER WILL HEAT BUT THE DRUM WILL NOT TURN. I HAVE CHECKED THE BELT AND IT IS OK. NOW WHAT
Hello. I can help you. Since the belt is ok there are only two other possible problems:

If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor:

  • Remove the belt.

  • Check for obstructions in the blower fan housing.

  • Manually rotate the shaft of the motor.

If the motor is very stiff, or impossible to rotate manually, and the blower fan housing is clear, you need to replace the motor.

If the motor rotates freely, run the motor momentarily with the belt removed and the blower in place. If the motor runs fine with the belt removed, there may be a problem with the idler pulley or the clothes drum. Try to rotate the drum by hand. If it is very difficult to move, correct any problem with the rollers or pulley, and then reassemble the dryer and try it again.

If the motor hums but doesn't rotate on its own even with the belt removed--yet you can turn it freely by hand--you usually need to replace the motor or the motor start capacitor.

Door switch Your dryer can't operate at all if the door switch is defective. It's inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. If it's defective, you need to replace it.

Whirlpool dryer will not spin
Since your dryer is "new" it is under warranty. I will explain the possible reasons why it will not spin. Then you can decide whether to make the warranty call or not.

If your dryer doesn't tumble, check these:

Belt
Motor
Door switch
Belt Dryers have a drive belt that turns the clothes drum. If the belt breaks, the drum stops rotating. Then you need to replace the belt, and often the idler pulley, because the pulley tends to wear out at the same time.

  • Remove the belt.

  • Check for obstructions in the blower fan housing.

  • Manually rotate the shaft of the motor.

If the motor is very stiff, or impossible to rotate manually, and the blower fan housing is clear, you need to replace the motor.

My dryer will not start. It is not locked. I've turned it off and unplugged it for 30 minutes. All the buttons work fine, but the timer just flashes when I push the start button. Help!
If dryer does not spin it is usually a problem with the belt or the motor. Check also door switch.
