The Thermistor is an OEM part for Whirlpool brand dryers. It is a temperature-sensing resistor that monitors air temperature changes during the drying cycle. The thermistor provides feedback to the control board on heating element performance and internal air condition. 

Symptoms of a failed thermistor include:

• Inaccurate temperature readings and selections  
• Improper or incomplete drying
• Safety issues from overheating due to lack of feedback
• Error codes displayed on the control panel

Causes can be related to normal wear and environmental exposure over time. Failure prevents the dryer from achieving optimal drying conditions.

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

Measuring 5.5 x 3.5 x 3 inches, this idler pulley assembly typically consists of a pulley mounted on a bracket or arm, which can pivot or move to apply the necessary tension to the belt.

Symptoms of a faulty Idler Pulley Assembly include:

• Loud squeaking or grinding noises during operation
• The dryer drum not spinning or rotating properly
• Excessive vibrations or shaking during the drying cycle

The Thermal Cut-Off Kit is an OEM replacement part for Whirlpool dryers, responsible for protecting the dryer from overheating by interrupting the power flow to the heating element if the dryer air temperature reaches a dangerously high level.  

Symptoms of a bad Thermal Cut-Off Kit include:

• The dryer not heating up 
• Excessive heat buildup within the dryer drum 
• Clothes not drying properly  

Causes of failure can include restricted airflow from a clogged lint filter or venting system or a malfunctioning heating element causing excessive temperatures. These issues can lead to the thermal cut-off being triggered to prevent overheating, necessitating the replacement of the kit.

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