Since the blower wheel is in the oven cavity it is at the same temperature as the oven.
is stopped while the oven is hot, the heat from the blower wheel is conducted down the shaft and into
the armature of the motor.
We recommend, at the end of the bake or roasting period, when the oven will be idle for any period of
time or before shutting down completely, that the doors be left open, and by use of the cool-down
position of the fan switch, the fan continues to run at least 5 minutes.
turned "OFF" when the oven is "HOT".
ADJUSTMENTS CALIBRATION. COOK THERMOSTAT.
Field recalibration is seldom necessary and should not be resorted to unless experience with cooking
results definitely proves that the control is not maintaining the temperature to which the dial is set.
To check oven temperature when calibrating use only a reliable mercury thermometer or preferably an
oven pyrometer. To check calibration proceed as follows:
1. Place the weighted thermocouple of the test instrument or reliable mercury thermometer in the
center of the oven.
2. Activate cook or power switch and high fan switch.
3. Turn oven temperature control dial to 400°F.
the oven control must be allowed to cycle twice before taking a test reading.
4. Check temperature reading when control just cycles "OFF" and again when control just cycles
"ON" as indicated by the cycling pilot lamp above control.
5. If the AVERAGE of the two temperature readings do not read within 15° of the dial setting,
recalibrate as follows:
6. Carefully remove the thermostat dial, not disturbing dial setting.
7. Hold dial shaft steady and with a thin bladed screwdriver turn calibration screw, located inside
the dial shaft clockwise to decrease and counter-clockwise to increase the temperature, e.g.: 1/4
turn = 35°F
8. Replace thermostat dial and repeat step 3 through 5 to verify correct adjustment has
been made.
HOLD THERMOSTAT CALIBRATION ON OVENS WITH COOK 'N HOLD OPTION
Calibration check of the HOLD thermostat is very important.
1. Place the weighted thermocouple of the test instrument or reliable mercury thermometer in center
of oven. Calibration should be checked with dial setting at 150°F.
2. Activate cook or power switch;
3. Set "HOLD" thermostat at 150°F and set timer at hold position.
off indicated by pilot lamp over control at least twice to allow oven temperature to stabilize.
4. Check temperature reading when control cycles 'OFF" and again when control cycles "ON" as
indicated by cycling pilot lamp.
5. If the average of the 2 temperature readings are not within plus or minus 10° of the dial
setting, recalibrate as follows:
6. Carefully remove the thermostat dial, not disturbing the dial setting.
7. Hold dial shaft steady and with a thin bladed screw-driver, turn calibration screw, located inside
the dial shaft, clockwise to decrease and counter-clockwise to increase the temperature,
1/4 turn = 12°
8. Replace thermostat dial and repeat steps 3 through 5 to verify correct adjustment has been made.
This action could shorten motor life.
