Important Tips for Kenmore Models

  • Kenmore refrigerators use specific error codes such as Er FF, Er IF, Er CF, Er CO, Er DH to indicate fan failures, communication errors, and defrost issues, which help pinpoint faulty components. (Home Guide Info

Possible Causes

Faulty evaporator or condenser fan motor

How to Identify: Error codes like Er IF or Er FF for evaporator/ice compartment fan and Er CF for condenser fan; reduced airflow and warmer temps even with compressor running. See code lists. (Home Guide Info

Part: Evaporator fan motor; condenser fan motor

Sensor or temperature sensor failure

How to Identify: Error codes such as Er FS, Er rS, Er HS, Er rt indicate sensor errors; unpredictable temp readings on display.

Part: Temperature sensors/thermistors (refrigerator, freezer, humidity, room)

Ice or frost buildup blocking airflow

How to Identify: Ice accumulation near evaporator and fans; error codes indicating fan failure may stem from ice blockage. (Home Guide Info

Part: Evaporator coils and fan areas

Dirty condenser coils

How to Identify: Poor heat dissipation, compressor runs continuously without effective cooling; visible dust/dirt on coils. (Machine Answered

Part: Condenser coils

Door gasket leak or warm air ingress

How to Identify: Warm air enters compartment, frequent beeping, error codes related to temperature instability; visible seal gaps. (Machine Answered

Part: Door gasket/seal

Main control board or communication error

How to Identify: Error codes like Er CO indicating communication failure; intermittent or no response from panel. (Home Guide Info

Part: Electronic control board/display control board

Defrost system failure

How to Identify: Codes such as Er DH or F dH indicating defrost issues; frost buildup on evaporator coils. (Home Guide Info

Part: Defrost heater, defrost sensor, defrost control

  3. Ensure proper sealing and test door closure.

Defrost ice buildup blocking fans

Easy several hours (manual defrost)
Tools Needed: none or gentle hair dryer on low
  1. Unplug refrigerator and leave doors open to melt ice.
  2. Clear melted water and clean area.
  3. Plug back in and monitor cooling.
⚠️ Safety First: Do not use high-heat devices that can damage components

Reset control panel

Easy 5–10 minutes
  1. Unplug refrigerator or turn off circuit breaker for ~2 minutes.
  2. Restore power and allow system to reboot.
  3. Check if error codes clear and cooling resumes.

Common Issues Reported by Users

  • Faulty temperature sensor causing incorrect readings
  • Blocked condenser coils leading to poor cooling performance
  • Defective control board malfunctioning and triggering error codes

User Suggested Solutions

  1. Check and clean the condenser coils. Unplug the refrigerator, locate the coils (usually at the back or underneath), and vacuum any dust or debris. Plug the refrigerator back in and monitor the temperature.

  2. Replace the faulty temperature sensor. Access the sensor (usually located in the fridge compartment), disconnect it, and install the new sensor according to the manufacturer's instructions.

  3. Inspect and, if necessary, replace the control board. This involves removing the back panel of the refrigerator, disconnecting the old board, and installing a new one. Ensure the power is off during this process.
