Chamberlain SW 2000-X3 For safety reasons, 11. GATE IS TOO SLOW, 9. GATE OPENS BUT DOES NOT CLOSE, 10. GATE DOESN'T STOP AT THE LIMIT, Mostly in cold weather or mornings:

4. THE CONTROL BOARD RESETS RIGHT AFTER GATE STARTS MOVING

1.Low AC voltage.

2.Inadequate and undersized power wiring between the main circuit breaker and the gate operator.

5. GATE STOPS AND REVERSES IMMEDIATELY AFTER IT STARTS
