A Speed Queen gas dryer in Crystal Lake, Illinois would start, run for only a few seconds, and then stop. The customer also reported a high-pitched buzzing noise, no heat, and a Door Open light that stayed on even when the door was closed.
Our technician tested the dryer and traced the multiple symptoms to a failed door switch. The door switch was replaced, and the dryer was tested to confirm it was operating properly again.

At first, this Speed Queen gas dryer appeared to have several different problems.
The customer reported:
The customer had already tried power cycling the dryer, but the symptoms remained.
When several symptoms appear at the same time, they don’t necessarily mean several different parts have failed. Testing the appliance can help determine whether those symptoms share a common cause.
Our technician tested the dryer and observed what happened during operation.
The dryer would start when the door was closed. After a few seconds, however, the Extended Tumble and Door Open lights would flash and the dryer would stop running.
That behavior provided an important diagnostic clue.
The dryer was not consistently recognizing the correct door position. Testing traced the problem to a failed door switch.
Our technician replaced the failed door switch on the Speed Queen gas dryer.
After installing the new switch, the dryer was tested again to verify that it would start, continue running, and operate properly.
After replacing the door switch:
The repair was completed without replacing multiple components based only on the original symptoms.
A dryer that starts normally but stops after a few seconds can have several possible causes. The symptoms and timing of the shutdown can provide useful diagnostic information.
On this Speed Queen dryer, the Door Open and Extended Tumble lights flashed before the dryer stopped. Testing eventually traced the problem to the door switch.
Because different failures can cause similar symptoms, a dryer that repeatedly starts and stops should be diagnosed before parts are replaced.
The dryer uses a door switch to determine whether the door is open or closed.
If the switch or related components are not working correctly, the dryer may behave as though the door is open even when it is physically closed.
On this dryer, testing confirmed a failed door switch. Replacing the switch corrected the problem.
The door switch is a small component with an important safety job.
It tells the dryer whether the door is open or closed. The dryer uses that information when deciding whether it is safe to operate.
When the door switch isn’t working correctly, the dryer may behave as though the door is open even when it is firmly closed.
Depending on the model and failure, symptoms can include:
A problem that appears to involve the motor, heating system, or controls can sometimes begin with something much smaller.
Yes. Depending on the dryer design and how the switch has failed, a faulty door switch can prevent operation or cause the dryer to stop unexpectedly.
On this Speed Queen gas dryer, the machine started but stopped after only a few seconds while displaying warning lights.
Testing identified the door switch as the cause, and replacing it restored normal operation.
