That $600 OTIS controller board I swapped in last week was a complete dud out of the box

Bought a rebuilt OTIS CH400 controller board from a supplier in Newark for $600 and it was dead on arrival. No power to the motor drive, no error codes, just nothing. Wasted a whole Saturday troubleshooting before I gave up and sent it back. Anyone else had bad luck with rebuilt boards from certain places?

Honestly, did you check the jumper settings before you fired it up? I’ve run into a few OTIS boards where the dip switches were set wrong from the rebuild shop, so the controller just sat there with no life. Ngl, $600 stings on a dud, but sometimes it’s a quick config fix rather than a total hardware fail.

Wait you actually had that happen too? I used to always skip checking the dip switches, figured if it was rebuilt it had to be right. But after getting burned on a board that looked brand new but had all the jumpers in the wrong spots I stopped assuming. So yeah, I totally changed my mind on that. It took me two hours of messing around before I even thought to look at the switches. Now I check them first thing even if the board came straight out of the box. Sucks but it saves a lot of headache later.

Did you check the voltage on the incoming power before you swapped it?
