Opener beeps or clicks but motor does not start; occurs mainly in cold weather.

Safety first: Do not repeatedly cycle the opener against a stalled motor.

• Warm the area: If possible, slightly warm the garage to see if operation improves, indicating temperature sensitivity.
• Check door movement: Manually move the door. If it is stiff, lubricate hinges and rollers with cold-weather-appropriate lubricant.
• Inspect and replace capacitor: Replace the motor start capacitor with a Mighty Mule-compatible part; cold often reveals marginal capacitors.
• Clean excess grease: If the rail is packed with heavy grease, clean and re-lubricate lightly per the manual.
