Customer Questions
I got a 045ACT from another company and it did not work. It was dated 10/2020 and said "Rev. C". The lights functioned as they should, however the up/down buttons would not move the door. They did not start the motor. My old board says "Rev. A" and is from 2017. It starts the motor and works fine except I need to replace it due to a intermittent connection block. The wire from the protection sensor does not make a good connection to the board. Do you have a "Rev. A" board for sale (or do you think a "Rev. C" should work and that I just got a defective "Rev. C" board)? Thank you.
Rev. C is the currently the most current version. Previous versions are not available. The version should not matter.
