Possible Causes

Faulty thermistor readings, Loose temperature sensor connections, Control board malfunction, Overheating due to poor ventilation

Safety first: Disconnect power before checking sensors or the control board.

Step 1 – Improve ventilation: Ensure the unit has proper clearances and that vents are not blocked.
Step 2 – Inspect thermistors: Check evaporator and bin thermistors for secure mounting and solid electrical connections. Replace any sensor with erratic resistance readings.
Step 3 – Control board inspection: Look for signs of overheating or damage on the board. Replace if necessary.

After repairs, observe several cycles to confirm stable operation.
