Dead Allister Garage Door Opener

[David]

The light bulb on my Allister Type IIA opener was flickering. So I
giggled it. There was a pop and the breaker was kicked off. I kicked
the breaker back on, but the door won't move. There is power to the
unit, but I can't figure out where the problem is. I don't see any
bare or loose wires.

Any idea on what is blown or how to figure out the problem?

Any help would be appreciated.

Thanks,
David

Use some other electrical device to plug into the receptacle that
your opener is hooked to. Verify that you have power at the
recep.

Unplug the unit. Open up the case where the power cord goes in.
If you know how to and have a current testing device, plug it back
in to verify that power is getting to the business end of the
cord.

If you have power that far, look for an in line fuse (similar to
an old automotive fuse). Test whether power is getting through
the fuse.

If you have power this far, the problem may be a circuit board or
the motor connections or motor. Any of these will probably make
it be easier to replace the opener.

Garage door openers don't have fuses. Some older units have manual
reset buttons but most now have a self resetting thermal overload
inside the motor housing. Sounds to me like something shorted out & it
probably damaged the logic board.
