The first thing you will need to learn to be able to easily repair your dryer is how to take it apart and how to put it back together again properly. Once you learn how to do that, the repairs will be very easy to do.
Voltages At The Terminal Block
In order for the dryer to be able to start, there have to be the right voltages present at the terminal block. If you don’t have the proper voltages at the terminal block, check the wall outlet.
The Door Switch
This switch is connected in series with the motor circuit and if the door is open or the switch is bad, the dryer will not do anything in any of the cycles that you try it on.
The Thermal Fuse
The thermal fuse is a safety device used to open the heating circuit to stop the dryer from heating if the temperature inside of the drum surpass 196 degrees Fahrenheit. The manufacturer recommends that the operating or cycling thermostat be replaced if the thermal fuse blows out.
The Start Switch
If the dryer is not starting in any of the cycles, the problem could be a bad start switch. There are two different types of start switches. The single pole single throw one and the relay activated one.
The Power Cords
You will need to check and make sure that the power cord is in good working order. Disconnect the dryer from the wall outlet and visually check the power cord for burn wires or plug terminals.
If the contacts inside of the timer won’t close to complete the motor circuit, the dryer will not do anything in any of the cycles.
If the motor is not starting and won't run, the dryer is not going to do anything. The motor needs to run to turn the tumbler and to complete the heating circuit.
You will need to make sure to watch the videos a few times until you know how to fix a not starting Whirlpool 29 inch electric dryer. Never assume that a part is bad without checking it and make sure it is bad before replacing it.
