Sprocket for Broken Automatic Door

Date: Wednesday, March 4, 2015
 Name: Angela
Problem: Our public entrance automatic door is not functioning. We have tried turning it off and turning it back on. It does not slide on its own. I left it off for 5 minutes and tried turning it back on after that time but it still does not work. The red power light does come on. I tried the "open" "close" and "automatic" settings, but it is not responding at all. Usually when it is cold it gets stuck, but it usually keeps working after a little push. It is not very cold out today, and it does not move even with a little manual help.
