Question and Answers

Q:

My 1/2 h.p opener hums, but does not work. The springs are fine, the red button light blinks, What's wrong?

A:

The led on the logic board is blinking a code. It will blink and then pause. The number of blinks tells you where the problem is.

I am sending you an image of the codes for the blinking.

Be sure the door isn't frozen to the floor. About the only thing that can cause the motor to hum and not move the door is if something is jammed in the opener, the door is frozen to the floor, or the capacitor has failed.
