IF OVEN OVERHEATS
If oven fails to cycle on and off and reaches temperatures above 550°F thermostat is faulty and needs replacing. If oven operates but is off from setting see calibration instructions.
Corrective Maintenance
CHANGING THE HEATING ELEMENT
1.Disconnect oven from power source.
2.Remove back cover and insulation from rear of unit.
3.Disconnect electrical leads from elements.
4.Remove any materials from bottom shelf and remove shelf from oven
5.Unscrew element bracket from oven and remove element.
6.Install new element and replace shelf in oven.
7.Attach electrical leads to new element and replace back cover.
CHANGING THE THERMOSTAT
1.Disconnect from the power source.
2.Remove control box cover
3.Loosen set screw in thermostat knob and remove knob. Remove chrome mounting ring (bezel).
4.Remove sensing tube from holder.
5.Remove wire connectors from thermostat leads and remove thermostat by pulling sensing tube through oven wall.
6.To replace new thermostat, attach electrical leads to thermostat and pass sensing tube through oven wall and into holder.
7.Mount thermostat to control box loosely with red indicting line in upward position. Place knob on thermostat stem and check rotation of knob. When knob turns freely, remove and tighten chrome mounting ring (bezel).
8.Replace thermostat knob and control box cover.
THERMOSTAT CALIBRATION & ADJUSTMENT
1.Turn on unit. Set control dial at desired temperature.
2.Allow control to cycle at least three times and observe temperature at the middle of the fourth cycle.
3.If calibration is required, carefully remove dial knob. Do not turn shaft.
4.Turn calibration screw in center of dial shaft clockwise to lower temperature and
5.Allow unit to cycle three times and observe temperature at middle of fourth cycle. Readjust calibration screw if necessary.
6.Replace dial knob.
