The wall outlet:
The first thing to check when your Whirlpool dryer
is not heating, is the wall outlet.
You need 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 cause for no heat
Before replacing the thermal
cutoff, make sure that the exhaust hose and the filter are clean.
The thermal
cutoff and the Hi-limit come together in a kit and should be replace at the same
time.
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
for 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
for the Whirlpool dryer 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 dryer is not heating.
