The WP2315531 Genuine OEM Whirlpool Refrigerator Defrost Heater is an original manufacturer replacement component designed for Whirlpool refrigerators and select compatible brands.

Appliance Kingdom proudly supplies this genuine OEM refrigerator part with fast Canada-wide shipping for homeowners, landlords, and appliance repair professionals.

A faulty defrost heater is one of the most common causes of excessive frost buildup, restricted airflow, and cooling performance issues in refrigerators. Replacing a failed defrost heater with a genuine OEM component helps restore proper automatic defrost operation and maintain reliable refrigeration performance.

What Does the Refrigerator Defrost Heater Do?

The defrost heater is mounted near the evaporator coils inside the freezer section of the refrigerator. During the automatic defrost cycle, the heater warms the evaporator coils to melt accumulated frost and ice. This process prevents excessive ice buildup that can block airflow and reduce cooling efficiency.

Because the defrost system plays a critical role in temperature regulation, using a genuine OEM heater ensures proper electrical performance, durability, and compatibility with the refrigerator's defrost control system. OEM components are engineered to meet the manufacturer's exact specifications for reliable long-term operation.

When a defrost heater fails, frost accumulates on the evaporator coils, reducing airflow and causing cooling problems throughout the appliance.

Common Symptoms Indicating Replacement

A defective WP2315531 defrost heater may cause:

• Excessive frost or ice buildup on evaporator coils
• Freezer not defrosting properly
• Refrigerator compartment becoming too warm
• Restricted airflow from freezer to fresh food section
• Inconsistent cooling performance
• Water leakage caused by defrost drainage issues
• Extended compressor run times
• Temperature fluctuations within the refrigerator

If your refrigerator exhibits these symptoms and diagnostics confirm a failed heater, replacing the defrost heater often restores normal operation. However, related components such as defrost thermostats, thermistors, timers, or control boards should also be inspected during troubleshooting.
