I had a good one tonight on call. Got to the job site to find the door off track. Fixed that and ran to the bottom floor doors wouldn't open. So I ran to other floors , same thing doors wouldn't open. Ran to the top floor doors open , put it on inspection ran the elevator down and put the door operator on manual. Doors opened and closed freely. Mind you this is a GAL MOVFR . Put it back on normal same thing no door open. Went to the machine room and checked out the door board in the controller. I noticed DO relay the light would flicker like it wanted to open but never stayed lit. Swaped DC and DO relays figuring I had a bad relay. No change. Has anyone seen this ? Is there something I'm missing that feeds DO ?
