Issue: Whirlpool Side-by-Side Refrigerator Not Fully Defrosting
If your Whirlpool side-by-side refrigerator is not fully defrosting, even after replacing the bi-metal and board, there could be several potential causes:
1. Defrost Thermostat: The defrost thermostat regulates the temperature during the defrost cycle. If it's faulty, the refrigerator may not defrost properly.
2. Defrost Heater: The defrost heater is responsible for melting the frost. If it's not working, the frost will not melt, leading to ice buildup.
3. Defrost Timer: The defrost timer controls the frequency and duration of the defrost cycle. A malfunctioning timer can disrupt the defrost process.
4. Evaporator Fan: The evaporator fan circulates air through the coils. If it's not working correctly, it can cause uneven cooling and defrosting issues.
5. Airflow Obstructions: Blocked vents or coils can restrict airflow, preventing proper defrosting.
6. Control Board: If the control board is faulty, it may not send the correct signals to initiate the defrost cycle.
To diagnose the issue, you may need to check these components and ensure they are functioning correctly. If you're not comfortable doing this yourself, it's advisable to contact a professional technician for assistance.
