Lower Heater Assembly

The lower ceramic heater has an approximate resistance value of 32 to 42 .

To remove the lower heater assembly:

1.Remove the oven from cabinet or wall opening. (See Oven Removal / Partial Removal.)

2.Remove the 2 Phillips-head screws from the bottom of each side of the outer cover.

3.Remove the 6 Phillips-head screws that attach the bottom to the oven.

Convection Heater Assembly and Thermistor

The oven must be removed from the cabinet or wall opening to access the convection heater assembly. (See Oven Removal / Partial Removal.)

The convection heater assembly is composed of an inner and outer fan blade, motor, heating element, and thermistor.

Remove the rear cover. Three Phillips-head screws hold the cover in place.

Thermistor

The thermistor must be removed before removing the convection heater assembly. The thermistor is attached to the convection heater assembly by a single Phillips-head screw.

The thermistor is connected to the power board at location CN8. The approximate values at room temperature are: Red - Blue = 400K Ω; Red - White = 290K Ω; Blue - White = 110K Ω.
