My Repair & Advice Featured Story
This Maytag dryer was bought in 1985 if memory serves. It has worked hard with few repairs done by yours truly over the years.
Thanks to the engineering and excellent design by Maytag staff, removing parts are relatively easy.
Once I opened the unit, I found it to be full of lint. I cleaned the entire inside and the vent pipe duct work.
I found the blower wheel assembly worn. Though it was not cause of my problem, I decided to change it along with the igniter, heater relay and the fan belt. I figured it needed some TLC after all these years and since I had the unit this far disassembled (my auto shop teacher frowned about using the word “taking apart”), might as well give it a new life.
As I had expected these replacements did not solve my problem. Next item, which is listed first in the repair manual as the possible cause was the cycling thermostat. The meter reading showed good, but since my problem was heat not cycling, I figured that was it. The factory one was no longer available, so I replaced it with an adjustable/generic one.
It did not help either. While testing the unit, I would see the new igniter get hot and glow, but the flame would not be present and the igniter would go cold. I kept hearing slight buzzing noises as well.
Even though the gas valve coils had been previously tested with a meter and showed ok, I could feel the gas valve unit, and feel the vibration. I opted to replace the coils.
As of this writing the unit is assembled again and several loads have been done and dried properly.
Knock on wood.
The Staff of the AppliencePartsPros.com have been very patient with me which was greatly appreciated.
