Electrolux Refrigerator Error Code 38

Error code 38 indicates the freezer temperature sensor has developed a short circuit. The control board monitors the electrical resistance of this thermistor to determine freezer temperature, and a shorted sensor sends an invalid signal that triggers the fault. The refrigerator may not control freezer temperatures correctly while this code is active. The sensor, its wiring harness, or the connector will need to be inspected and tested to locate the fault.

Operating the refrigerator with a shorted freezer sensor is not recommended for extended periods. Without an accurate temperature reading, the control board cannot properly regulate the compressor, which could result in the freezer running too warm and spoiling frozen food or running excessively and causing other component wear. Food safety should be monitored closely, and the repair should be addressed promptly.

Resetting the refrigerator by unplugging it for several minutes may temporarily clear the error code from the display, but the code will return if the underlying short circuit has not been repaired. A reset does not fix a shorted thermistor or damaged wiring. A proper repair requires diagnosing and resolving the actual electrical fault before the code will stay cleared.

A knowledgeable DIYer can perform basic diagnostics such as inspecting the wiring harness for visible damage, checking the connector for corrosion, and using a multimeter to measure thermistor resistance. If the thermistor has shorted internally, replacing the sensor is a straightforward repair involving unplugging the old sensor and installing a compatible replacement. However, if the fault is in the main control board wiring or the board itself, a qualified technician may be needed to complete the repair safely.

If only the thermistor needs replacement, parts typically cost between $15 and $50 depending on the specific model, making it one of the more affordable repairs. Labor charges from a technician generally range from $80 to $200 depending on your location and service provider. If the wiring harness or main control board is also involved, the total repair cost can be higher, potentially ranging from $150 to $400 or more.
