We have not switched brands. The drives have always been made by
Yaskawa but they market them through different companies that put
different labels on them. We have also switched models but only as the
old models get obsoleted by newer and better models. The problem you
describe is most likely the door switch gone bad. Jumper the wires
attached to it and let me know if that fixes the problem.
