nrod7 Posted April 30, 2016 Share Posted April 30, 2016 I Bought a used DN 276 E. I was told that 2 columns were not working. I found that the selection button bar was broken. The bar was a quick fix. I was going to test vend the motors. When I noticed that the column # 1 was not in the homing position. I release the brake and backed the cam back into a homing (groove) position. I thought to myself "easy fix". But when I depressed the door button, the column # 1 motor began to turn by passing homing positions ( grooves) an finally resting high on the cam. What do I need to check? nrod7 Link to comment Share on other sites More sharing options...
AZVendor Posted April 30, 2016 Share Posted April 30, 2016 The motor switch is bad and needs to be replaced. They are rated at 125vac but have only 5vdc running through them. When they get some corrosion on the internal switch contacts they can't pass the low voltage properly. If you need any/some you can email me at rbepic4gatgmaildotcom.
