Kenmore Freezer Error Er dH

Kenmore Freezer

High Severity
Warning: If your Kenmore appliance displays the Er dH error code and you are unsure how to proceed, turn off the appliance and contact a qualified technician. Some errors require professional repair to avoid further damage or safety risks.

What Er dH Means on a Kenmore Freezer

The Er dH error code indicates a defrost heater problem. The automatic defrost system has failed — typically due to a blown thermal fuse or failed defrost heater element.

Common Causes

  • Blown defrost thermal limiter (thermal fuse)
  • Failed defrost heater
  • Defrost timer or control board failure

What You Can Do

  1. If the freezer has heavy frost/ice buildup on the back wall, this confirms defrost failure.
  2. Manually defrost by unplugging for 24–48 hours.
  3. A technician can test and replace the heater assembly or thermal fuse — these are inexpensive parts.
