TOP CELL MOTOR REPLACEMENT
1.
Mark the fans and motors so they will not be mixed up.
2
At the rear of the oven, assemble three screw assemblies. A screw assembly consists of one 3mm hex
head screw, one flat washer, and one rubber washer in that order. The rubber washers are to aid in
vibration isolation.
3
Using RTV, put a very small dab of RTV on each support leg of the motor. Place rubber washer (not the
rubber washer from the screw assembly in Item 2 above) on each leg and position them so that they are
centered on the screw holes.
4
Put a small amount of RTV into each of the fan mounting holes on the cell plate.
5
Insert one screw assembly into a hole on the motor base and place the motor up against the cell face.
Center the holes and hand-tighten the screw.
CAUTION: Orient the motor so that the wires will reach the terminal block.
6
Insert the second screw into a hole on the motor base and hand-tighten it.
7
Finally, insert the last motor mounting screw into the last hole and hand-tighten it.
8
Using the 3mm T-handle, tighten all three screws until they are tight and the motor is securely fastened onto
the cell plate.
9
Properly connect the motor wires to the connector block. (Red=L2, Yellow=L3, Blue=L1).
10
At the oven, place the fan mounting gauge in the cell up against the cell face with the opening of the V
facing the rear of the oven and surrounding the motor shaft. Make sure that the sides of the gauge are
between the screws in the cell plate. Hold the gauge in place. See drawing for the fan gauge.
11
Place the matching fan blade onto the motor shaft of the motor that you just installed. Note that the fan has
two setscrews and the motor shaft has two flats on it.
12
With the fan blade resting against the gauge, tighten the setscrews with a 3mm hex key bit on a torque
wrench set to 50 inch pounds(5.65 N.m). Remove the gauge by sliding it forward and down out of the cell.
13
Retrieve the heater panel for this cell and set the rear of it into place in the cell between the bracket and the
cell. Be careful not to bend the thermocouple wire. Prop the heater panel up from the front so that you can
reconnect the heater wires.
14
Reconnect the wires to the panel referring to the SKETCH made when the panel and wires were removed.
Use a 2.5mm hex head key and a 7mm open end wrenche. Be careful not to tear the foil.
15
Reconnect the wires to the over-temperature switch
.
15
Carefully place the thermocouple wire in its protective 1.7mm vinyl tubing through the correct hole in the
panel.
If the thermocouple(s) location was NOT marked (circle) prior to removing the panel, then count four
rows from the left and seven holes (6 visible) from the front to locate the correct hole.
16
Once the thermocouple is located in its proper hole, raise the heater panel in place.
17
Replace the front panel bracket and fasten it with the Philips style screw. Remove the vinyl tubing
protecting the thermocouple(s).
18
Install the support angle brackets on the left and right side of the heater panel.
19
Carefully bend the thermocouple into its correct place and replace the clamp and screw. Tighten the screw.
