ADJUSTMENTS

ADJUSTING DOOR CHAIN MECHANISM

The door chain mechanism causes the left and right doors to open and close together. To adjust the door chain mechanism, do the following:

1.Remove lower front panel that covers the door chain mechanism (shown below).

2.Close both doors.

3.Check the positioning of the chain on the sprockets. There should be five regular links and one master link visible on the front side of each chain. If not, open the turnbuckles and reposition the chain over the sprockets.

4.Adjust the turnbuckles so that the right door closes about 1/4" to 1/2" inch ahead of the left door. The left door should be pushed tight over the friction catch so both doors are completely closed against the frame.

5.Secure the turnbuckles by tightening their locknuts.

ADJUSTING DOOR SWITCH

The door switch detects when the oven doors are open. As adjusted at the factory, when the doors are opened more than 2 to 4 inches, the burners and fan should shut off (unless the fan is switched to “COOL” mode). To adjust the door switch, do the following:

1.Remove lower front panel that covers the door chain mechanism.

2.Close both doors.

3.Check that the door switch striker bar is attached to the door chain's first and second links (after the master link). If necessary, adjust or repair the door switch striker bar.

4.With the doors closed, loosen the two screws that hold the door switch bracket to the oven frame (shown below). Slide the bracket left or right until the plunger arm on the door switch is being depressed 1/8".

!CAUTION

Do NOT adjust the door switch so that the plunger arm is completely depressed and is hitting the switch body. This could distort the arm and cause the switch to operate poorly.

5. Tighten the screws holding the door switch bracket to the oven frame.
