Whirlpool dryer is not heating
The wall outlet 240 volts
The first thing to check when your Whirlpool dryer won't heat is the wall outlet to make sure that the dryer is getting the proper voltages. On an electric dryer there should be 240 and 120 volts present at the terminal block.
The 240 volts are necessary for the electric dryer to produce heat.
The thermal cutoff
The thermal cutoff together with the hi-limit thermostat protect the dryer from overheating if there there is a problem with the airflow in the dryer.
When there is a problem with the airflow in the dryer, the thermal cutoff will blow, a blown thermal cutoff or a bad hi-limit thermostat could be the reason why your Whirlpool dryer is not heating.
Before replacing the thermal cutoff, make sure that the exhaust hose and the filter are clean.
The operating thermostat
The operating thermostat is in charge of controlling the temperature inside of the dryer. A bad operating thermostat could be the cause why your Whirlpool dryer is not heating.
The heating element
The heating element is the part that produces heat in the dryer. The element has between 10 and 50 ohms of resistance. The resistance to the flow of electrons is what produce heat.
The timer
The timer is the distribution center in the dryer. It takes electricity from the terminal block and direct it to the different circuits in the dryer.
When you set the timer on any of the cycles that requires heat, the contacts of the terminals with the black & blue wires should be close. Burnt contacts inside of the timer could be the reason why your Whirlpool dryer is not heating.
The motor switch
The motor switch is a safety device use in the motor to prevent the dryer from heating when the motor is not running. When the motor gets to full speed, this switch closes allowing the heating circuit to be completed.
A bad motor switch could be the reason why your Whirlpool dryer is not heating.
So...as you could see, there are many parts that could be the reason why your Whirlpool dryer won't heat.
