IF OVEN FAILS TO OPERATE – NO HEAT
1. Check power source.
2. Check power cord continuity. Replace cord assembly if faulty.
3. If pilot light glows, voltage is being supplied by elements. Check elements. Check element continuity.
If defective, replace.
4. If thermostat cannot be heard clicking on and off when dial is rotated, and if pilot light fails to
operate, replace thermostat.
IF OVEN OPERATES BUT FAILS TO REACH TEMPERATURE
1. Check name plate for proper voltage. Check voltage at outlet. The 240-volt ovens will operate on 120
volts, but will not reach optimum temperature.
2. If voltage is correct, check element continuity. The K-900 and K-1000 have 1000-watt elements. If
one element checks badly, it is suggested to replace all three elements at this time and save remaining
elements for emergency spares.
NOTE: If oven operates but interior temperature varies widely from thermostat setting, see calibration
instructions.
IF OVEN OVERHEATS
If oven fails to cycle on and off and reaches temperatures above 550°F thermostat is faulty and needs
replacing.
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. From oven interior, unscrew element brackets from oven floor and pull elements through rear wall to
remove from oven.
5. Install new elements and brackets.
6. Replace electrical leads on elements as per wiring diagram.
7. Check that element leads and terminals are not grounded to oven body.
8. Replace insulation and back 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 counter-clockwise
to increase temperature.
5. Allow unit to cycle three times and observe temperature at middle of fourth cycle. Readjust
calibration screw if necessary.
6. Replace dial knob.
