Convection Bake Element - GE PT920 Technical Service Manual

The convection fan will turn on (after a short delay).
The fan may cycle on and off, and change direction
in any of these modes, to best distribute hot air in
the oven. The convection fan shuts off when the
door is opened.
There is a 2.5 μf run capacitor connected across the
CW and CCW windings of the convection fan motor.
This capacitor provides a phase shift for the change
in motor direction. An open or shorted capacitor will
stop the motor.
The convection fan motor has approximate
resistance values between the following wires:
Red and Blue: 167 Ω
•
Red and Gray: 76 Ω
•
Blue and Gray: 91 Ω
•
To remove the convection fan motor assembly:
1. Remove convection fan blade. (See
.)

3. Remove the rear access panel. (See
Panels.)
4. Disconnect the convection fan motor wire
harness.
5. Remove the three 1/4-in. hex-head screws that
hold the convection fan motor to the back of the
oven.

Convection Bake Element

Note: The resistance of this component can be
tested from the EOC. (See
The element is rated at 2500 watts, has an
approximate resistance value of 22 Ω, and draws
approximately 10.6 amps.
The convection bake element is located on the back
wall of the oven and can be removed from inside the
oven cavity.
To remove the convection bake element:
1. Disconnect the power from the oven and
remove the oven racks.
2. Remove the four 1/4-in. hex-head screws that
hold the convection cover to the back wall of the
oven cavity.
3. Remove the four 1/4-in. hex-head screws that
hold the convection bake element to the back
wall of the oven cavity.
4. Carefully pull the convection bake element
towards the front of the oven until the element
terminals are accessible.
5. Disconnect the wires from the convection bake
element.
