Light does not come

Allistter Manufacturonc Co. All-O-Matic Electric Door Control Model SR - Light does not come on and light bulb is fine. I see similar questions came up before but sorry, I wasn't able to find answers to those. Maybe a faulty limit switch or relay could be the problem. Would love to see any troubleshooting info, or owner's manual electric schematic (where to find?). Any kind suggestion will be much appreciated.
Thank you,

Unless you know how to check electrical and electronic systems it is very difficult to explain troubleshooting procedures. It could be a bad receptacle, a relay or another electronic problem somewhere on the control board.
