Troubleshooting

The Keen oven models K-1000 M&T requires a minimal amount

of electrical knowledge to repair if necessary.


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 OVERHEATS

If oven fails to cycle on and off and reaches temperatures above 250

°F thermostat is faulty and needs

replacing.

Corrective Maintenance

CHANGING THE HEATING ELEMENT

1. Disconnect oven from power source.
2. Remove back cover, insulation and element cover.
3. Remove cover plate from handy box and remove wire connectors from element leads.

8. Replace insulation, element cover, back cover, and handy box cover plate.


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.
