Electrolux Refrigerator Error Code SH

SH indicates a shorted circuit has been detected in the fresh food compartment temperature sensor. The code appears on the fresh food display while the freezer display continues to operate normally. It means the sensor is sending a signal with abnormally low resistance, which the control board cannot interpret as a valid temperature reading. The underlying cause is typically a failed thermistor, damaged wiring, or moisture at the sensor connector.

Because the fresh food sensor is shorted, the control board cannot accurately monitor or regulate the temperature in the fresh food compartment. This puts food safety at risk, as the fridge may not maintain proper cooling in that section. It is best to address the fault promptly and use a standalone thermometer to verify the compartment temperature in the meantime.

Repair costs depend on the failed component. A replacement fresh food thermistor typically costs between $15 and $50 for the part alone. If professional labor is involved, total repair costs including diagnosis and installation generally range from $100 to $250. Control board replacement, if required, can push costs higher, often in the $200 to $400 range for parts and labor.

A knowledgeable DIYer can attempt to diagnose this fault by inspecting the fresh food sensor wiring for visible damage, checking the connector for moisture or corrosion, and testing the thermistor with a multimeter. If the thermistor reads near-zero resistance, replacing it is a straightforward repair. However, if the wiring harness or control board is involved, professional repair is recommended.

A power reset may temporarily clear the SH code from the display, but the code will return if the underlying fault in the sensor circuit has not been repaired. Resetting without fixing the root cause does not restore accurate temperature monitoring. The fault needs to be corrected at the component level before the error will stay cleared.
