ADJUSTMENT OF OVEN TEMPERATURE
WARNING
THIS PROCEDURE SHOULD ONLY BE PERFORMED BY A QUALIFIED SERVICE TECHNICIAN
FAMILIAR WITH ELECTRICITY AND ELECTRICAL COOKING EQUIPMENT REPAIR.
If the oven temperature requires adjustment, do the following.
1. Unplug the oven (or disconnect the power) and remove the lower front panel, right side panel, and
insulation. Locate the temperature control board on the control panel assembly (as shown in the
following drawing). Plug the oven back in (or reconnect power) and leave the side panel and insulation
off to perform this calibration.

2. Clip the oven-temperature probe directly to the oven center shelf. Close the oven and place the
thermometer on the front. Set the temperature selector to HIGH and turn the oven ON. Let the oven
heat up and allow the oven temperature light to cycle twice. Observe the low and high temperature of
the last cycle.
3. The board has three potentiometers that have miniature set screws for temperature adjustment (see
picture below). Turning the screw on a potentiometers clockwise will Increase the temperature, and
turning it counterclockwise will decrease the temperature. Using a micro screwdriver, adjust the HIGH
temperature potentiometer by a small amount. Allow the oven to cycle twice and check the oven
temperature. Repeat until the oven temperature is 375°F ±10°F (191°C ±6°C).
WARNING
ENSURE THAT NEITHER YOU NOR YOUR SCREWDRIVER COMES IN CONTACT WITH THE
LIVE POWER IN THE UNIT.
