Haier Refrigerator Error Code 3rd LED Freezer flash

The 3rd LED Freezer flash indicates an Ice Maker Sensor (ICE SNR) error. The sensor located below the ice maker has either failed or is producing a reading outside the acceptable range. The control board uses this sensor to monitor temperatures in the ice-making zone, and this fault will typically disable or interrupt ice maker operation until the issue is resolved.

The refrigerator's main cooling and freezing functions will generally continue to operate even when this error is active, since it specifically relates to the ice maker sensor circuit. However, the ice maker itself may be disabled or behave erratically. You can continue using the refrigerator for food storage, but avoid relying on the ice maker until the sensor issue is repaired.

If only the ice maker thermistor needs replacement, parts costs are typically in the range of $10 to $40, and a technician's labor for the repair may add $75 to $150 depending on your location. If the issue stems from wiring harness damage, costs are similar or slightly higher depending on harness availability. A main control board replacement, if needed, is the most expensive scenario, with parts ranging from $80 to $200 or more plus labor.

Start by inspecting the wiring harness and connectors between the ice maker sensor and the control board for damage, corrosion, or loose connections. If the connections look intact, use a multimeter to measure the resistance of the ICE SNR thermistor and verify it falls within range for the current compartment temperature. If the sensor reads open or shorted, replace the thermistor. If the sensor and wiring are both good, the main control board may need to be evaluated.

A power reset may temporarily clear the error code from the display, but the fault will return if the underlying sensor or wiring problem has not been fixed. Because the control board continuously monitors the ICE SNR circuit, it will re-detect the fault and re-trigger the error at the next diagnostic cycle. A permanent resolution requires repairing or replacing the faulty component.
