Error code Slow flash
Appliance Ice Maker
Quick answer

Slow flash on older CLR60, CLR2060 and CLRCO2075 clear ice makers points to a thermistor plug or thermistor problem, and the unit stops.

Model compatibility: U-Line reuses codes across series and model years, so Slow flash may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Control board LED slow flash: sensor problem (thermistor plug disconnected or thermistor failed open); the unit stops operating.

On older U-Line clear ice makers, a slowly flashing control board LED reports that the board has detected a sensor problem. The unit stops operating while it flashes. Manuals for the CLR60 and for the original CLR2060 and CLRCO2075 boards describe it, and all three are legacy models.

Two causes in the manuals

The first is a thermistor plug that has come off the control board. The second is a thermistor that has failed open. Unplug the unit before anyone opens the service panel; a technician is the right person to inspect the plug and the thermistor.

Reading the light

A steady light is the healthy condition. Anything that flashes, slow or rapid, stops the machine.

Nearby codes

  • Rapid flash: the high-heat signal on the same LED.
  • Zone T / Amb Thrm: open and shorted thermistor circuit messages on a newer clear ice machine.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
