Amana Refrigerator BRD18V2E Freezer not defrosting

The Defrost Thermostat is an OEM part for Whirlpool refrigerators. It monitors the temperature of the evaporator coils and triggers the defrost cycle when the coils get too cold, preventing frost buildup and ensuring efficient cooling.  It operates by closing the heater circuit to initiate the defrost cycle. It opens the circuit when the temperature rises above 55 degrees Fahrenheit. It then resumes operation when the temperature drops to 20 degrees Fahrenheit.

Causes of a bad defrost thermostat can include regular wear and tear, exposure to moisture, or electrical issues. Over time, the thermostat may lose accuracy or stop working altogether, leading to frost accumulation or inefficient cooling.

Symptoms of a bad defrost thermostat include:

• Excessive frost buildup in the freezer
• The refrigerator running continuously or not cooling properly
• The defrost heater not activating
• The refrigerator cycling on and off frequently

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

The Refrigerator Defrost Timer is an OEM Replacement Part designed to manage the automatic defrost system in Whirlpool freezers. Housed at the top inside of the appliance, this component shuts off the cooling system and activates the defrost heater. The timer operates at 120V 60Hz and activates for 33 minutes every 8 hours. The dial on the timer can be turned clockwise to advance it into and out of defrost.

Causes of a faulty Defrost Timer Kit can include electrical issues, mechanical wear and tear over time, or problems with the timer's internal components.

Symptoms of a bad Defrost Timer Kit include:

• Freezer not defrosting properly, leading to excessive ice buildup
• Refrigerator running constantly or not cooling effectively
• Condensation or moisture issues inside the refrigerator
• Error codes related to the defrost system
