Kenmore Refrigerator Error Code 30
Ice mold heater not reaching temperature
What this error means
Code 30 means the ice mold heater failed to heat the mold to release temperature during harvest. The module timed out waiting for the thermistor to confirm the mold warmed enough to eject cubes.
How 30 is detected
Kenmore refrigerator models lock the door or lid before energizing fill, heat, or high-speed spin. 30 means the latch switch never sent a "locked" signal to the main control, or the lock motor did not complete its travel. On Kenmore 106.51133210, Kenmore 106.62562101, and similar variants, clothing caught in the gasket, a misaligned strike, or a failed latch assembly are the most common mechanical causes—not the board itself.
Inspect the door gasket perimeter and strike alignment before replacing the latch. Open mold heater element inside the ice maker body is reported frequently on this code. After correcting mechanical issues, remove the ice maker and inspect heater wires for heat discoloration. If the latch clicks but 30 persists, the door lock switch or wiring harness to the control board likely needs testing with a multimeter.
Do not force the door open during an active cycle; wait for the lock to release when the board de-energizes the lock motor—usually two to three minutes after canceling power on most Kenmore units.
Common causes
- Open mold heater element inside the ice maker body
- Burned heater connection at the ice maker harness
- Failed mold thermostat opening too early
- Heavy scale insulating the mold from the heater
Step-by-step fixes
- 1Remove the ice maker and inspect heater wires for heat discoloration
- 2Measure mold heater resistance—it should not read open
- 3Run Service Test 58 heater activation and watch for mold surface warming
- 4Replace the ice maker if the heater is open or does not warm during test
When to call a technician
Mold heater replacement is part of the ice maker head—service can swap the assembly if harvest repeatedly fails with code 30.
Affected models
- Kenmore 106.51133210
- Kenmore 106.62562101
- Kenmore 106.74202410
Prevention & maintenance
- Wipe the door gasket weekly and avoid overloading items against the seal—30 often starts as a slow leak or latch misalignment.
- Record when 30 appears in the cycle and whether it clears after a 60-second power reset on your Kenmore refrigerator—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for 30; Kenmore uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting 30; reversed plugs on pumps and valves cause immediate repeat faults.
