Title
Whirlpool WED87HED Hi-Limit Thermostat/Switch Replacement
Introduction
Use this guide to replace the hi-limit thermostat/inlet thermistor on your Whirlpool Duet WED87HED Dryer. These components are combined into one unit so if either component fails you will replace the whole unit.
These components control your dryer's temperature, the inlet thermistor lets the Cycle Control Unit (brain) know what the inlet temperature is, and the hi-limit thermostat shuts off the heater if it overheats. The hi-limit will reset and allow the heating element to operate again after a cooling period.
When the hi-limit fails the dryer may not heat at all or sometimes it will overheat until the thermal cutoff or thermal fuse operates. When the inlet thermistor fails, your machine will display an error code.
This guide is rated as difficult, mainly because of the amount of disassembly required. None of the steps are particularly difficult in themselves, except perhaps removing the front lower bulkhead.
