Gas Dryer Heating Issue - Timer controlled by thermostat?

Since a couple of weeks ago, the Auto Dry Regular setting stopped working on my Maytag MDG5000BWW dryer. It ran overnight but still not dry clothes.

I tried to troubleshooting and found:

  1. With all kinds of timer setting, the igniter may heats up and turn on the gas lit several times at the beginning, but not stay on longer enough.

  2. The timer is working in the TIME DRY/AIR FLUFF setting only but not on AUTO DRY neither REGULAR or WRINKLE FREE FABRICS setting.

Due to the dryer ran overnight, I thought that caused by a bad timer. So I ordered a timer and replaced it today. Unfortunately, the replaced timer didn’t fix the issue.

I thought the timer and thermostats are separate control systems. If that caused by bad thermostats, at least the timer should stop the dryer when the time cycle is over. But in AUTO DRY setting, the dryer will keep going, none stop.

Appreciate any suggestion and recommendation.

I’ve seen where the coils for the gas valves go bad. Follow this link and it should be #7 and #8 in the diagram, replace both.

FYI,

You have an “auto Advance” type dryer. in the " Auto Dry" setting the heat does control the voltage to the timer motor causing the timer to advance.
The “cycling” or regulating thermostat has to operate(open and close)properly.
It sounds like you may have a clogged exhaust vent, and will need to check and clean the hole pipe system.(you could also disconnect the exhaust vent from the back of the dryer and run a couple of loads of clothes on the auto dry setting, to check).
You may also have a set of weak gas valve coils on the burner assembly,

AP3094251

You will want to observe the burner/ignition process and make sure you get a flame(ignition) at the burner. It may take 20 to 30 minutes, or a couple of burner cycles before the coils fail.

Good Luck,

Thanks for the quick response! I’ll give a try and keep you posted.

FIY,

Great, I’m pretty sure you’ll find the problem in one of these areas.

Good Luck,

Thanks Joe,

It should not be “a clogged exhaust vent” issue. It was dirty, but not now. I deeply cleaned it last weekend by unassambled the exhaust system.

Is the [COLOR=#0000ff]Part number: AP3094251[/COLOR] the right parts? I can’t find my dryer model MDG5000BWW in its support list.

FIY,

Yes this part, is the correct part. It is a “kit” and consists of both gas valve solenoids(coils) it will work on your machine, it works on all Maytag gas dryers with a “two coil” gas valve.

No problem, and Thanks

Joe,

As you said, the problem caused by coils. After I replaced both of them by using parts that you provided parts # and I ordered from AppliancePartsPros.com, the dryer was back to normal. So far we tried 4 heavy loads already.

Thank you and AppliancePartsPros.com so very much!

I fixed the problem after I replaced both of coils.

Thank you so much and your time!
