Introduction |
| Use this guide to replace the hi-limit thermostat/inlet thermistor on your Whirlpool Dryer. These components are combined into one unit, so if either component fails, you will need to replace the whole unit. | | | These components control your dryer's temperature. The inlet thermistor lets the main board 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. | | | ***This guide will work for most Whirlpool dryers.*** This guide is written with a model WED87HED dryer. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same. |
