A DJUSTING D OOR C HAIN M ECHANISM
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.
T EMPERATURE C ONTROLLER (Standard-Control Models Only)
The calibration of the temperature controller should not be changed until sufficient experience with cooking results has
definitely proved that the temperature controller is not maintaining proper oven temperatures. Before any recalibration is
attempted, the oven temperature should be checked by the following procedure:
1. Remove all trays and pans from the oven.
2. Place a thermocouple or a reliable mercury oven-type thermometer at the center of the middle rack.
3. Turn the oven ON and set the temperature control knob to 400°F.
4. The amber “heat on” light will go out when the oven temperature is reached.
5. Allow three cycles for the temperature to stabilize.
6. Read the thermocouple or thermometer immediately after the light goes out for the third time, and again immediately
after it comes on the next time.
7. If the average of these readings varies by more than 10°F from the dial setting, recalibrate by the following procedure.
Recalibration should be attempted only by a competent service technician.
