TOP CELL MOTOR REMOVAL
1 Remove power from the oven.
2 Remove the screw holding the thermocouple in place on the cell face. Using a permanent black marker,
circle the thermocouple on the heater face. Carefully straighten the thermocouple wire and cover it with a
piece of 1.7mm vinyl tubing. This will aid in relocating the thermocouple when reassembling the cell later.
3 Remove the support angle brackets on the left and right side of the heater panel
.
4 Remove the Philips style screws holding the front heater panel bracket. Remove the bracket.
5 If the heater panel does not fall down by itself, using a hex key wrench, carefully insert the short end into a
hole in the heater panel and gently tug down on the heater panel. You may need to use the 3" putty knife to
push the insulation guard clear of the heater panel.
6 Lower the heater panel far enough to gain access to the heater wires on the inside of the cell. Block the
panel up with a 10" (or 254mm) 4x4 block of wood to relieve the strain on the wires.
7 Document the wire placement on the connections on top of the heater panel as you will have to replace
them later in the exact same order.
8 Remove the four wires by using a 2.5mm hex head key and a 7mm open end wrenche hold the bottom nut
(closest to the panel) steady while the other unscrews the top nut to free the wire.
9 IF THE HEATER FOIL TEARS, YOU WILL HAVE TO REPLACE THE ENTIRE HEATER PANEL.
10 Disconnect the two wires on the thermal switch.
11 Remove the heater panel and set it aside.
12 Remove the fan assembly from the motor shaft. Using a 3mm hex head wrench, loosen the two setscrews
on the fan blade enough to remove the fan blade from the motor shaft. Save the fan blade to return to
Vitronics Soltec with the motor.
13 At the rear of the oven, SKETCH the locations of the wires in the terminal block and then remove the wires.
Using a 3mm hex head wrench or T-handle, remove the three screws holding the motor in place on top of
the cell.
14 Remove the fan motor. Tap on the motor to break it loose from the cell.
15 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.
