Scheduled Maintenance

The manufacturer recommends that the operator periodically clean all flux residue from heating

elements and brackets. Excessive flux buildup on elements may cause hot spots and shorten element life.



Troubleshooting

The Keen oven model KF-100A 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. (Strain relief may have to be removed

from power cord to gain access.)

3. If cord and power supply check okay, remove leads from thermostat terminals and check for

continuity across terminals. If continuity is not present across thermostat terminals, replace

thermostat.

4.

If thermostat is good, check continuity of elements and element wiring. If elements or wiring are

faulty, replace.



IF OVEN OVERHEATS

1. If oven overheats, adjust thermostat. (See “Temperature Setting” section.)

2.

If thermostat calibration fails to lower temperature, replace thermostat. (See “Corrective

Maintenance” section.)



IF OVEN HEATS BUT FAILS TO REACH TEMPERATURE


1

. Calibrate thermostat. (See “Temperature Setting” section.)
