A Failed Defrost Timer Causes Frost to Choke Your Evaporator Coils — WP2183400 Restores Automatic Defrost Cycles and Stops the Freeze-Up

When the defrost timer fails, your refrigerator stops initiating automatic defrost cycles. Frost accumulates unchecked on the evaporator coils, blocking airflow until the fridge can no longer cool — food warms, the compressor overworks, and energy consumption spikes. The WP2183400 is the genuine Whirlpool OEM defrost timer kit that directly replaces 2162044, 2162052, and 2183400, restoring timed defrost cycles on compatible ET, RT, KTRS, and KTRP series refrigerators.

• Refrigerator not cooling despite compressor running
• Thick frost or ice buildup on the back wall of the freezer or fridge compartment
• Evaporator fan running but no cold air circulating
• Fridge cycles on and off but never reaches set temperature
• Manually advancing the timer initiates defrost — confirms timer is the fault
• Food spoiling faster than normal without obvious cause

• OEM Part Number: WP2183400
• Replaces: 2162044, 2162052, 2183400
• Type: Defrost Timer Kit

Skill Level: Beginner to Intermediate (20–30 minutes).
Unplug the refrigerator before beginning. The defrost timer is typically located in the control housing inside the fridge compartment or behind the rear panel. Note the wiring harness orientation and photograph before disconnecting. Remove the old timer, install the new WP2183400 in the same position, and reconnect all wires. Manually advance the timer to confirm it initiates a defrost cycle before reassembling. Restore power and monitor for 24 hours to confirm normal cycling.
