Kenmore Refrigerator Error Code rS E

The rS E code indicates a refrigerator compartment sensor error caused by a short circuit or open circuit in the temperature sensor circuit. The control board monitors resistance signals from this sensor to regulate cooling in the fresh food section. When the signal falls outside acceptable parameters, the code is triggered. The first place to check is the wiring connector labeled CON7 and the resistance between the two white wires in that connector.

It is not recommended to rely on the refrigerator for food storage while the rS E code is active. Without a functioning temperature sensor, the control board cannot accurately regulate cooling in the fresh food compartment, which means temperatures could rise to unsafe levels without any warning. Perishable foods should be moved to another refrigerator or cooler until the fault is resolved.

If only the thermistor needs replacement, parts typically cost in the range of $15 to $50 depending on the specific model, making it one of the more affordable refrigerator repairs. If professional labor is required, total repair costs including diagnosis and installation generally range from $100 to $250. A wiring harness repair or control board replacement would push costs higher, so accurate diagnosis before ordering parts is important.

Yes, in many cases this repair is DIY-friendly. Start by unplugging the refrigerator and inspecting the CON7 connector for looseness or corrosion, then reseat it firmly. If that does not resolve the issue, use a multimeter to measure resistance between the white wires at CON7 to determine whether the thermistor or wiring harness needs replacement. Replacing a thermistor is a straightforward repair that typically requires only basic tools.

A reset, such as unplugging the unit for a few minutes, may temporarily clear the code if the fault was caused by a momentary glitch or a loose connector that reseats during the process. However, if the thermistor or wiring is genuinely faulty, the code will return once the refrigerator resumes operation. A proper resistance check at CON7 is needed to determine whether the underlying fault has been corrected.
