Kenmore Refrigerator ER RF Error Code: Refrigerator Compartment Sensor Fault

Quick Answer

Kenmore refrigerator ER RF means the refrigerator (fresh food) compartment temperature sensor has failed. The sensor is located inside the refrigerator section, usually mounted on the back wall or under a cover near the air vent. It measures ambient air temperature and sends readings to the control board to regulate cooling.

It measures ambient air temperature and sends readings to the control board to regulate cooling. A failed sensor causes temperature swings or continuous running. Test with a multimeter: expect 5k-10k ohms at room temperature. Replacement cost is $10-20 for the sensor.

What Does the ER RF Code Mean?

ER RF means the Kenmore 795 refrigerator compartment temperature sensor has failed. Test with a multimeter and replace if reading is open or out of range. Sensor costs $10-20.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Refrigerator compartment sensor thermistor failure40%
Wiring fault between sensor and control board24%
Debris or food residue on sensor affecting readings22%
Control board input circuit failure14%

Symptoms You May Notice

  • ER RF displayed on front control panel
  • Refrigerator section too warm or too cold
  • Compressor running continuously
  • Fresh food spoiling faster than normal
  • Temperature display showing incorrect reading

Can you reset a Kenmore refrigerator to clear the ER RF code?

Unplug the appliance for 60 seconds, then reconnect power to clear stored error codes.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Unplug the refrigerator

Unplug the refrigerator. Locate the refrigerator compartment temperature sensor: it is typically mounted on the back interior wall of the fresh food section, behind a small plastic cover or clip.

2

Remove the sensor cover if present (usually one screw or

3

Set a multimeter to resistance (ohms) mode

4

At room temperature (68-75F)

5

Replace the sensor if it fails the test

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What is the difference between ER 1F and ER RF on a Kenmore 795?
Both are temperature sensor failures but in different compartments. ER 1F is the freezer defrost sensor on the evaporator coil. ER RF is the fresh food compartment ambient temperature sensor on the back wall of the refrigerator section. They are different parts at different locations.
Will ER RF cause my food to spoil?
Yes. Without an accurate temperature sensor reading, the control board cannot properly cycle the compressor and fans. The refrigerator section can fluctuate above safe temperatures (above 40F) and cause food spoilage. Address ER RF within a day or two.
Where exactly is the ER RF sensor located inside the Kenmore 795?
The fresh food compartment sensor is typically mounted on the upper rear interior wall of the refrigerator section, near the air vent that distributes cold air. It may be under a small rectangular plastic cover held by one screw. Refer to your model's service manual for the exact location.
I replaced the ER RF sensor but the code came back after one day. What is causing it?
If the new sensor triggers ER RF quickly, check the wiring harness between the sensor and the main control board. Look for pinched, cut, or corroded wires. If the harness checks out, the main control board's sensor input may be failing and the board will need replacement.
Can I test the ER RF sensor without a multimeter?
You can do a basic visual check: ensure the sensor connector is fully seated and wiring is undamaged. However, without a multimeter you cannot confirm thermistor failure. A multimeter is inexpensive ($10-20) and essential for accurate diagnosis.
