Door opens but wont close

[stampedecarwash]

Hello one of the exit doors open when you pish the open button but it wont close when you push the close button. It stops when you keep pressing the stop button while opening but it will keep opening if you let it go. The only way to bring the door down isto disengage the motor and manually bring the door down. Ive changed the eye sensors, loop sensor and also relays and still same issue.

Sounds like the limit switch to me.

The operator is a Liftmaster EGJ which are pretty compact, i dont think that they have a limit switch

UPDATE: I'm almost certain that its the contractor or the Contact Blocks on it. Comparing to other doors I noticed the blue switch on the Contact Block (https://www.eibmarkt.com/cgi-bin/ei...4f3dba27564debae39066b/Product/View/NS0730405) doesn't come down when I push the Stop button. So its either the contractor (https://www.gatehousesupplies.com/ProductDetails.asp?ProductCode=G038024K&CartID=1) or its the Block mounting on it.
