Kitchenaid Refrigerator KSRV25FHWH00 Frost buildup

The Defrost Thermostat is an OEM part for Whirlpool refrigerators. It is responsible for monitoring the temperature of the evaporator coils. When the coils reach a certain temperature, the thermostat signals the defrost heater to turn on and melt any ice or frost buildup. This ensures proper airflow and prevents excessive ice formation.

Causes of a bad defrost thermostat can be attributed to normal wear and tear over time or electrical malfunctions.  

Symptoms of a bad defrost thermostat include:

• Excessive ice buildup in the freezer section.
• Inadequate cooling in the refrigerator compartment.
• Frost or ice accumulating on the evaporator coils.

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

The Whirlpool Defrost Timer is an OEM replacement part for Whirlpool refrigerators. The defrost timer regulates the automatic defrost cycle, which prevents ice buildup on the evaporator coils in the freezer compartment by sending a signal to the defrost heater to turn on and melt any ice buildup on the coils. 

Causes of a bad defrost timer can include mechanical wear over time, electrical failures, or internal component damage. Prolonged usage and voltage spikes can also affect the timer's functionality.

Symptoms of a bad Defrost Timer include:

• Excessive frost buildup in the freezer compartment
• The refrigerator or freezer not maintaining the set temperatures
• Unusual noises coming from the appliance 
• The appliance running continuously without cycling off

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