What LO means on your Jenn-Air ice maker
A Jenn-Air LO error is essentially the opposite problem of overheating — the unit has dropped below its intended operating temperature and is running too cold. That might sound harmless for something meant to make ice, but overcooling can freeze the water lines feeding the ice mold solid, which paradoxically stops ice production entirely rather than helping it.
This usually traces back to a sensor or thermostat giving the control system bad information rather than anything wrong with the compressor’s ability to cool — the system is doing exactly what it’s told, it’s just being told the wrong thing.
Symptoms
- LO shown on the display
- Ice production stopped or drastically reduced
- Frozen water lines or fittings if accessible for inspection
- Unit feels colder than normal to the touch inside
Common causes
- Failed temperature sensor — the sensor reports a falsely warm reading, so the system keeps cooling well past where it should stop.
- Stuck thermostat — the thermostat is jammed in the cooling position and never cycles off.
Troubleshooting steps you can try
- Thaw the unit fully. Unplug for four to six hours to let any frozen water lines thaw completely, laying towels around the base to catch meltwater as it drains.
- Adjust the thermostat if accessible. After thawing and restarting, if your model has an accessible thermostat dial inside the unit, try nudging it slightly warmer and monitor whether overcooling recurs.
When to call a technician
If the sensor reads incorrectly when tested against a known temperature, or the thermostat won’t cycle off no matter the setting, these are component-level failures that need replacement rather than adjustment. schedule a service visit so a technician can swap the faulty sensor or thermostat — repeatedly thawing and restarting only provides temporary relief if the underlying part is bad.
