We have replaced the finisher main board. We do not get 24v at the switches. Any ideas?

what about power supply? have you jigged the doors to take the readings?

I got a rash of those door sensors going bad lately might wanna test the sensor itself.

I got out to this account with the tech. After trouble shooting, the finisher power supply 24v supply was only 5v. We swapped out the power supply and the problem was resolved.
