Wine cooler cycles on and off very frequently (short cycling), with the compressor starting and stopping every few minutes.

Safety: Unplug the unit before accessing sensors or the control board.

Steps to reduce short cycling:

• 1. Verify temperature stability: Use an independent thermometer to check if the actual temperature is fluctuating widely or if the issue is mainly compressor behavior.
• 2. Reposition thermistor: Ensure the cabinet sensor is not too close to the evaporator or a vent. Move it slightly into free air if possible.
• 3. Avoid rapid door openings: Frequent door use can cause rapid temperature swings and more cycling.
• 4. Replace faulty sensor: If the thermistor readings are erratic (tested with a multimeter), replace it with the correct Insignia part.
• 5. Control board replacement: If sensor placement and condition are good but short cycling persists, the main control board's algorithm may be faulty and require replacement.

Note: Short cycling can shorten compressor life; addressing it promptly is beneficial.
