Whirlpool Dryer: overheating and shutting off

Professional Repair Guide

What is this symptom?

Is your Whirlpool dryer overheating and shutting off unexpectedly? This common issue often stems from restricted airflow due to vent blockage or a malfunctioning thermistor. If your dryer gets excessively hot and stops mid-cycle, itâ€™s essential to address the problem promptly to prevent further damage.

Urgency: Medium

Important Tips for Whirlpool Models

Whirlpool dryers use moisture/temperature sensors and an autoâ€‘dry algorithm; overheating can trigger safety shutdown even if load appears dry.

Possible Causes

Restricted airflow (vent/duct blockage)

How to Identify: Dryer overheats, drying times increase, lint buildup visible at lint trap or behind dryer; air flow reduced at exterior vent

Part: Dryer venting system (lint trap, duct, exterior vent)

Faulty thermistor or cycling thermostat

How to Identify: Dryer overheats even with clean airflow, thermostat fails to cycle heating element off at correct temp

Part: Thermistor / Cycling thermostat

Drive motor overheating/overload safety shutdown

How to Identify: Dryer runs briefly then stops, cools and restarts; motor may hum or struggle, airflow compromised

Part: Drive motor / blower assembly

Faulty heating element or timer allowing continuous heating

How to Identify: Dryer gets excessively hot quickly, cycles do not regulate heat; timer may not advance properly

Part: Heating element assembly / Timer

User Suggested Solutions

Clean the venting system. Disconnect the dryer from power, remove the vent hose, and check for blockages. Clean out any lint or debris. Reattach the hose and test the dryer.
Replace the faulty thermostat. Disconnect the dryer from power, locate the thermostat (usually near the heating element), and test it with a multimeter. If it's faulty, replace it with a new one.
Clean the lint trap and dryer drum thoroughly. Remove the lint trap, wash it with soap and water, and ensure the drum is free of lint buildup. This should be done regularly to prevent overheating.
