BOTTOM CELL MOTOR REMOVAL
1 If the Oven is belt-only, disconnect the belt at the master link and unthread the belt from the
tunnel. See the procedure for disconnecting the conveyor belt.
2 If the Oven is rail-only, disconnect the conveyor chains at the master links and unthread them
from the tunnel. See the procedure for disconnecting rails and chains.
3 If the Oven has a combination rail/belt conveyor, disconnect and unthread the chains first and
then the belt from the tunnel. See the procedures for disconnecting rails and chains and
disconnecting the conveyor belt.
4 Remove all outer panels to allow access to the underside of the Oven. Remove power from the
Oven.
5 Remove the screw(s) holding the thermocouple(s) in place on the cell face. Using a permanent
black marker, circle the hole the thermocouple(s) pass through on the heater face. Carefully
straighten the thermocouple wire and cover it with a piece of 1.7mm vinyl tubing. This is to aid
relocating the thermocouple when reassembling the cell.
6 Remove the support angle brackets on the left and right side of the heater panel.
7 Remove the Philips screw holding the front heater panel bracket. Remove the bracket.
8 Remove the Philips screw holding the rear heater panel bracket. Remove the bracket.
9 Using a hex head wrench, carefully insert the short end into a hole in the heater panel and gently
pull up on the heater panel.
10 Tip the heater panel on its side to gain access to the heater wires on the inside of the cell. Block
the panel in place to remove the heater wires.
11 SKETCH the wire placement on the connections on the heater panel. They will have to be
replaced in the same order.
12 Remove the four wires by using a 2.5mm hex key and a 7mm open end wrenche. Uses one to
hold the bottom nut (closest to the panel) steady, while the other unscrews the top nut to free the
wire.
IF THE HEATER FOIL TEARS, IT CANNOT BE REPAIRED, AND THE HEATER PANEL ASSEMBLY
MUST BE REPLACED.
13 Disconnect the thermal switch, then remove the heater panel and set it aside.
14 Remove the blower from the motor shaft. Using a 3mm hex head wrench, loosen the two
setscrews on the blower enough to remove the blower from the motor shaft. Save the blower to
return with the motor.
15 Go to the rear of the oven and go in under the cell that has the motor to be removed. Document
the locations of the wires in the terminal block. Using a 3mm hex head wrench or T-handle,
carefully remove the three screws holding the motor in place on the cell.
16 CAUTION: Hold the motor with one hand while you remove the last screw as the weight of
the motor may cause it to fall on top of you.
17 Remove the Cell Fan motor. You may have to tap on the motor to break it loose from its mount
on the cell.
18 Scrape all RTV off the cell in the motor area. Clean all grease, dirt and RTV from the shaft hole
area and the motor support areas.
