Kitchenaid Dryer KEYS850LE2 Timer will not advance

This Dryer Cycling Thermostat is an OEM replacement part for Whirlpool dryers. It monitors internal temperatures and cycles power to the heating element accordingly. The thermostat ensures the drying air reaches and maintains the optimal heat level selected for fast, effective drying results.

Symptoms of a bad cycling thermostat include:

• The dryer not heating or heating inconsistently  
• Frequent trips of the circuit breaker
• Slower than normal drying times
• Burned clothes due to overheating

Causes of failure may be related to normal wear over time, dust buildup affecting sensor readings, or incorrect thermostat calibration. 

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

This 3-cycle mechanical timer controls and advances the selected drying program. It sequences power to the dryer's circuits so cycles start, progress, and shut off at the correct times, restoring reliable, predictable operation.

• Advances the dryer through each stage of the selected cycle and turns circuits on/off at the proper time
• Routes power to the drive motor and heating circuits as the timer cam progresses
• Can help when the timer won't advance, the dryer runs too long or won't shut off, a cycle won't start, or timing is inconsistent
• Restores accurate cycle timing and dependable cycle completion

• Disconnect power before servicing; if gas, also shut off the gas supply
• Remove the control knob/panel to access the timer
• Photograph wiring; move wires to the new timer one terminal at a time to match positions
• Secure the timer, reassemble, and run a short test cycle to confirm proper advance and shutoff
