Dryer wont run

Dryer runs then shuts down wont start up for an hour: or 20 minutes

Bad motor windings

also check for a b ad cycling thermostat

Hi,

There can be many reasons why your dryer will not start or turn...

The most common causes are the belt breaking or jumping off, or the motor going bad...

Here are a couple of tips that I wrote will help you to figure out why your dryer will not run...

Yes you have a bad motor. Its shutting off on its overload and wont start back up again until it cools back down.

If the timer is not advancing but is ticking that could be the problem. A dryer achieves a set temperature and stays there for a certain amount of time during a cycle. If the time never changes it may just keep heating up until the heat sensor shuts it down. If it is starting and shutting down its likely still related to the heat sensor.

Sounds like a faulty high limit or cycling thermostat. The thermostat tells the dryer to heat until the interior of the dryer reaches a certain temp. It should be mounted on the exhause duct inside the back of the dryer. It should look something like the one in the picture:



Hope this helped and best wishes.

If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.

Normally, this is what happens during an automatic cycle:

• The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.
  
  
• When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)
  
  
• The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.
  
  

This cycle continues until the clothes are dry. But…if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

If your dryer stops during its cycle, wait ten minutes and start dryer again. If dryer starts, then the motor was overheating.

Solution, Check for lint blockage around the motor and for possible overloading. If dryer repeatedly stops during its cycle, especially during consecutive loads, replace motor.

Good luck

I imagine this has got an electronic timer ? If so then it's probably the timer board that's faulty.
