4.Apply lubricant at the top of the door catch assembly to lubricate the internal spring. See LUBRICATION under GENERAL.
5.Close the doors and check them for proper alignment.
A.Doors should be centered and parallel at the top and bottom in the oven cavity opening as outlined under DOOR ADJUSTMENT.
6.Open right side door and view the left side catch ball and door strike position. Ensure catch ball is resting upon the angular surface of door strike. Repeat on opposite door.

A.If adjustment is necessary, loosen mounting screws then slide door strike from front to back until roller ball rests upon the angular surface of the door strike. Tighten screws and check operation.
B.If proper adjustment cannot be achieved, add shims beneath the door strike. Repeat step 6. DO NOT BEND THE DOOR STRIKE.
7.Each oven door should open with a force of 8 to 25 pounds when pulled at the handle. The adjustment must allow the doors to remain closed during normal operation and allow opening without exertion by the user.
NOTE: The amount of tension on catch ball determines the opening force of door.
A.Adjust catch ball tension as follows:
1)Turn set screw inside the catch assembly housing clockwise to increase tension on catch ball and counterclockwise to decrease tension on catch ball.
2)Continue adjustment until proper door operation is achieved.
DOOR CHAIN ADJUSTMENT (SIMULTANEOUS DOORS)
