My Whirlpool Dryer Timer Wouldn't Work and Dryer Remained ON

The dryer runs fine but the timer wouldn’t engage and eventually switch the dryer off. I ordered a new timer, watched a few videos, and swapped it out with no problems.

With the new timer installed, I twisted the new timer for a very short run. I could hear it ticking/buzzing. Started the dryer…it ran fine and shut off a few minutes later with the buzzer. Great!

Not so fast. Today, we ran a full load for about 60 minutes. The new timer didn’t budge at all and the dryer ran until we halted it by closing the door.

I’m so confused. It worked the first time, on a shorter time setting, but now it’s not working. Anyone have any ideas? Thank you.

What is the model number of your machine, and what cycle did you use (timed dry - auto dry).

Hi, my dryer is a WED4900XW0 and we used timed dry.
