Dryer sounds the buzzer when the timer is off. When turned on a cycle it hums and the heater gets hot . I get no continuity across the timer contacts,but don,t know if that,s bad.

Here are your parts includes a wiring diagram. Parts for Maytag SDE2606AYW Dryer - AppliancePartsPros.comSounds like it could be a motor problem. Are you sure that it is not just a broken belt? The below assumes that the belt is OK The motor has two centrifugal switches on it. They close when the motor gets close to operating speed. One of them connects in the heating coil. This ensures that there is air flow before the timer turns on. Since you have heat there is either a problem with the heating coil or this switch is closed but the motor is not turning. The second one switches out the start winding, if left in circuit this would overheat the motor. So if it is activated there is no start winding when the motor is at rest and it will often just sit there and hum while trying to start. The centrifugal mechanism that activates the switches may be clogged solid with lint or is just dirty. Could also be that the motor is toast. |

Thanks for the prompt reply! The belt is intact and the hum sounds like the start windings are interrupted,as you described . I have recently blown out the motor with compressed air when replacing a drum roller,but i will take the drum back out and look at it. How can i test the start windings when i am in there ? What does the centrifugal switch look like, can i clean the contacts?

You cannot clean the switch contacts.
Since it sounds like both switches are being activated I suspect it is the centrifugal mechanism that is the culprit.
It is pretty hard to get at as it is an integral part of the motor. it is on the motor shaft by the switches. |

Thank you denman,for your words of wisdom. Upon closer inspection it is exactly as you said,the centrifugal mechanism is broken. Your insight prevented me from throwing un-needed parts at this problem. If i replace the motor are there any other parts besides a belt that i should consider?

Yes.
I would check the rear drum support roller, the idle wheel and the front drum support glides for wear.
Also this is a good time to check/clean your vent system. |

Thanks denman for the tips. I notice the tensioner roller turning with difficulty so i cleaned the roller bore and axle with fine scotchbright. the roller bore does not look like bronze so must need lubrication.What do i use,lithium or moly or what,i have read a few others wondering about what gets grease and what does not ?

In this type of unit no grease is used.
As far as lubricating shafts/bearings a couple drops of sewing machine or 3 in 1 or any good oil should do.
Do not go crazy with the oil as it will hold lint.
Do not use WD40. |
