Electrolux Ice Maker Error Code SH

The SH code means the ice maker has detected a shorted mold thermistor during diagnostic test 56C. The mold thermistor is a temperature sensor on the ice mold that the control uses to manage freezing and harvest cycles. A short condition means the sensor circuit is reading abnormally low or near-zero resistance, which is outside any valid operating range. The ice maker will not function normally until this fault is resolved.

The SH error is not an immediate safety hazard, but it does prevent the ice maker from operating correctly. The control system disables normal ice-making operation when it detects a shorted thermistor because it cannot reliably monitor mold temperature. You should address the fault promptly to avoid extended periods without ice production, but there is no risk of fire or injury from the error code itself.

Repair costs depend on what component has failed. If only the mold thermistor needs replacement, parts typically run in the range of $20 to $60, plus labor if a technician is doing the work. Professional diagnostic and repair visits generally cost between $100 and $250 depending on your location and the extent of the repair. If the ice maker control board is at fault, costs will be higher, as control boards are significantly more expensive than thermistors.

Start by accessing the 6-pin connector at the front of the ice maker compartment, disconnecting it, and measuring resistance across pins 1 and 4 on the ice maker side using a multimeter. If the reading is near zero ohms, the thermistor itself is likely shorted and will need to be replaced. Also inspect the wiring harness between the thermistor and the connector for any pinched, chafed, or moisture-damaged wires, as wiring faults can produce the same short reading.

A simple reset will not permanently clear the SH code because the fault is confirmed through an active diagnostic test, test 56C, that runs as part of the ice maker's self-check routine. If the underlying cause, such as a shorted thermistor or damaged wiring, is still present when the diagnostic runs again, the code will return. The error will only clear once the root cause is corrected.
