Refrigerator cycles on and off frequently, with short run times and frequent starts.

Safety: Unplug the refrigerator before testing sensors or accessing the control board.

• Check temperature settings: Avoid extreme setpoints that can cause rapid cycling. Use recommended factory settings.
• Door usage: Minimize frequent door openings, which can cause the unit to cycle more often.
• Test thermistors: Verify that temperature sensors provide stable, accurate readings. Replace any that show erratic resistance changes.
• Control board: If sensors are good but cycling remains abnormally short, the control board may be mismanaging compressor run times and should be evaluated by a technician.
