Question and Answers

Q:

Why does my Whirlpool dryer seem to be running at the same temperature on all settings?

A:

If the heater element is cycling on and off then the dryer likely has a failed operating thermostat and it is cycling on the high limit thermostat. You could also have a shorted heating element that would cause the dryer to heat constantly and not cycle.

The operating thermostat is designed to "open" and cycle off the heating element at about 150 degrees. Once it cools back down about 20 degrees to 130 degrees it will normally "close" and L1 voltage will again be supplied to the heating element so that it resumes heating until the temperature reaches 150 degrees then the cycle repeats. If the operating thermostat is stuck closed, the dryer will continue to heat way above the normal temperature of 150 degrees. The heating element will continue to heat up until the high limit thermostat reaches 221 degrees at the heater box. If the dryer is cycling off when it reaches the higher temperature and cools down for a while (about 20 degrees) before heating back up then replacing the operating thermostat (part 3387134) should fix this problem. You can order this part from the Sears PartsDirect website. To access and replace this component, unplug the dryer and remove the back panel. The component locations are shown in the image below. The thermostat heater should have violet wires. The operating thermostat should have the red and red/white wires attached to it. Replace the operating thermostat and reassemble the dryer. Run a test cycle with a medium load of wet laundry in the dryer. This should fix your temperature problem.

If the heating element is on constantly, I recommend that you unplug the dryer and remove it from the housing to check it for damage. You could have a broken element that is shorting to the cabinet ground if a failed operating thermostat is not causing the dryer to overheat.
