6.3.2 Thermostat Calibration

If the oven components are operating but the unit
is not cooking properly, the thermostat may need
calibration To calibrate, proceed as fol lows
1. Attach a thermocouple lead to the bulb of the
thermostat and close oven doors
2. Place power switch in the ON position
3. Set thermostat dial at 400°F and carefully remove
the switch control knob
4. Allow the unit to heat until the indicator light has
gone out twice
5. Note the temperature reading on the ther-
mocouple
a) If the temperature reading is off 50° or more,
the thermostat must be replaced
b) If the reading is off less than 50°F, adjust the
thermostat setting using a fine blade screwdriver
in the stem of the thermostat
6. With the oven temperature set at 400°F, the
cycling should retain a peak of 420°F and a low of
380°F after two stabilizing cycles A good
indication of proper calibration is the temperature
at which the burners ignite and shut off It should
be:
Cut off 400-405°F
Cut in 380-385°F
7. After completing calibration, apply Duco cement
or equivalent to the adjusting screw of the
thermostat and replace the knob
