Maytag Dryer DE7400 Too hot

The Hi-Limit Thermostat is an OEM replacement part for Whirlpool gas dryers. As a safety device, it monitors internal drum temperatures during cycles to prevent overheating.  If the temperature rises to 200 degrees Fahrenheit, the heating element will cut off. It will resume operation once the temperature drops to 170 degrees Fahrenheit. Featuring two (2) male 1/4" terminals, this thermostat is designed for flush mount installation. Its electric dryer hi-limit thermostat is rated at L200-30F

Causes of a bad hi-limit thermostat can include exposure to excessive temperatures over an extended period. Failure to safely vent moist air outside may cause thermal expansion cutting off electrical control.

Symptoms of a bad hi-limit thermostat include:

• Inability to complete dryer cycles or premature shutoffs  
• Flashing error codes or indicators related to heat
• Sudden lack of heat even when dryer functions normally
• Tripping of household circuit breakers during drying

This OEM part is also compatible with brands like Maytag, Amana, and Kenmore models. Replace yours to ensure thermal safety.

This internal-bias thermostat regulates dryer drum temperature by cycling the heat on and off, helping maintain consistent drying performance and protect against overheating.

• Controls the cycling temperature of the heating circuit to prevent underheating or overheating
• Helps resolve symptoms like no heat, not enough heat, long dry times, or temperature swings
• A faulty thermostat may cause overheating that can trip the thermal fuse
• Located on the blower housing on many models

• Disconnect power and shut off gas (for gas dryers) before servicing
• Access the blower housing; note wire positions and transfer one at a time
• Mount the thermostat flush to the housing for proper sensing
• After installation, run a test cycle to verify proper heating

The Blower Wheel Assembly is an OEM part for Whirlpool dryers, designed to circulate air through the drum and out the vent. This part is responsible for the movement of hot air across the clothes to evaporate moisture so that clothes dry evenly and quickly.  

Causes of a bad Blower Wheel Assembly can include debris buildup leading to wear and tear on the fins or a damaged hub disconnecting the wheel from the motor shaft. 

Symptoms of a bad Blower Wheel Assembly include:

• Unusual noises when the dryer is running.
• Clothes taking longer to dry or not drying fully.
• The dryer overheating due to restricted airflow.
• A noticeable decrease in the exhaust.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.
