Unit frequently turns on and off (short cycling) with very brief run times.

Safety first: Unplug the unit before accessing internal components.

• Ventilation: Ensure proper clearance around the cooler and clean the condenser coil and fan.
• Sensor check: Inspect compartment sensors for proper placement and damage. Replace if readings are erratic.
• Observe behavior: After cleaning and resetting, plug in and monitor. If the compressor starts and stops within a few seconds repeatedly, the overload or compressor may be failing.
• Professional diagnosis: Short cycling can damage the compressor. Have a technician check compressor current draw, overload function, and control board relays.
