Er-dH Errors: Resolving Kenmore Defrost Heater Issues


Dealing with Kenmore defrost heater issues can be frustrating and time-consuming. If you’re encountering the dreaded Er-dH error code on your refrigerator, you’re not alone. This guide aims to provide detailed information on identifying the causes of Er-dH errors, troubleshooting steps, and effective solutions. We’ll also cover preventative measures and some frequently asked questions to help you better understand and resolve these issues.


Understanding Er-dH Errors

Er-dH errors are associated with the defrost heater system in Kenmore refrigerators. The error code indicates that there’s a problem with the defrost heater, its related components, or the control board. The defrost heater is responsible for melting frost buildup on the evaporator coils, ensuring optimal cooling performance.


Common Causes of Er-dH Errors

There are several possible causes for Kenmore defrost heater issues, including:

  1. Defective defrost heater: It’s possible that the heating element is broken or otherwise not doing its job.
  2. Faulty defrost sensor: The defrost cycle is activated when the sensor detects an appropriate temperature. If the sensor is broken, the heater won’t turn on or will run for too long.
  3. Damaged or loose wiring: Electrical connections might be compromised, affecting the heater’s functionality.
  4. Faulty control board: The control board governs the defrost cycle and heater operation. A malfunctioning board can disrupt the defrosting process.


Troubleshooting and Resolving Kenmore Defrost Heater Issues

To troubleshoot and resolve Er-dH errors, follow these steps:

  1. Inspect the defrost heater: Unplug the refrigerator and access the evaporator compartment. Visually inspect the heater for signs of damage, such as burn marks or broken coils. If damaged, replace the heater. For more information on defrost heater replacement, visit this guide.
  2. Test the defrost sensor: With a multimeter, test the defrost sensor’s resistance at room temperature. If it doesn’t match the specified value, replace the sensor.
  3. Check wiring connections: Inspect the wiring for damage or loose connections. Repair or reattach any compromised wires.
  4. Examine the control board: Look for visible signs of damage or burnt components. If the control board appears faulty, consult a professional technician for further assessment and possible replacement.

Preventative Measures

To prevent Kenmore defrost heater issues and Er-dH errors, follow these preventative measures:

  1. Regular maintenance: Clean the condenser coils and check for frost buildup every six months. This ensures proper airflow and efficient operation.
  2. Inspect seals: Regularly inspect the door gaskets for cracks or damage. Replace them if necessary to maintain optimal temperature and humidity levels inside the refrigerator.
  3. Monitor temperature settings: Avoid setting the refrigerator or freezer temperature too low, as this can cause excessive frost buildup and strain the defrost heater.
  4. Ensure proper ventilation: Keep the area around the refrigerator clear to allow for adequate air circulation and prevent overheating.


Frequently Asked Questions

Q: Can I continue to use my refrigerator with an Er-dH error?

A: While the refrigerator may still function with an Er-dH error, it’s essential to address the issue as soon as possible. Continued use may lead to further damage or inefficient cooling performance.

Q: How much does it cost to replace a defrost heater or other components?

A: The cost of replacement parts varies depending on the specific component and refrigerator model. On average, a defrost heater can cost between $30 and $60, while a control board may range from $100 to $300. Labor costs for professional repair services will also vary.
