Welcome. My name is XXXXX XXXXX would be glad to assist.

Looking at my copy of the manual, an error code of 2 flashes up arrow and 2 flashes down arrow equates to a logic board failure unfortunately.

Good news is, they are available.

Page 35 of the Manual, double check yours if you would.

You will see the left column has a 2-------- for the Up arrow flashes
This is 2 flashes

Right column has a 1-5--------- for the down arrow flashes
This can be anywhere from 1 flash up to 5 flashes, so any number between 1 and 5 is the same fault.

Internally it is probably triggered in a different way to result in 1 flash or another number up to 5 flashes.

But the end result is the same, unfortunately.

A new logic board is needed.

See page 35

It may be a plus, to add a small plug in style surge protector on the opener as a safety factor in case of surges being involved to damage the electronics.
