Roper dryer won't start

I would check the door switch first. That is the easiest and cheapest part to break and foul your dryer.

Since you did not post a model number it is difficult to determine what features your dryer has. However, here are some of the most common causes of a dryer that will not start:

1. Blown Thermal Fuse. Located on the blower fan assembly and is a white plastic looking component with two wires on it. A measurement across the fuse should read a short (0 ohms) if good. Make sure all measurements are taken with the dryer unplugged and the wires disconnected from the fuse.

2. Broken dryer belt. Some dryers are equipped with a broken belt switch that will shut the dryer off in the event of a broken belt. This prevents the belt from wrapping around the drive motor shaft. You will need to open the dryer and do a visual check to determine if the belt is still in one piece around the drum.

3. Broken door latch. You can usually tell if the latch is working properly by leaving the door open and toggling it with your hand. If the drum light shuts off when depressed, more than likely you don't have a door latch problem.

4. Bad centrifugal switch on the drive motor. The drive motor has a centrifugal switch that engages when the motor begins to spin. Some dryer motors have a separate centrifugal switch that can be replaced, while others have an internal switch which requires the entire replacement of the drive motor.

5. Bad drive motor. Commonly caused by failure of the internal centrifugal switch or bad motor windings. I have found the main connector plug on the motor loose at times causing the dryer to fail too.

6. Bad start switch on the control panel.

7. Bad control board on the control panel (if equipped). Not all dryers have a control board. Some only use a simple start switch.

I hope I've given you enough items to think about. If you have questions, or require additional assistance, please post back with your model number so that I may be able to provide you with better assistance. I hope this helps.
