HEATERS AND THERMAL CUTOUTS - NOTES
Figure 11B. Thermal Cutouts
Operational Testing
The heating elements require the control board to
be properly functioning. The solid state relay LED
should be illuminated for the heater element to be
turned on. When testing the heater elements the
temperature in the oven must be less than 274°C
so that the thermostats remain closed.
Test Procedure
Close oven door. Check for operating voltage
across heater terminals. Unplug oven and check
continuity across heater coils. If a heater coil
shows high resistance coil is probably open.
Replacement
Refer to detailed procedure in the REPLACE-
MENT section of this manual.
