POWER BEFORE REMOVING ANY COMPONENTS.

REMOVAL INSTRUCTIONS 

OVEN 

Thermostat, Contactor, Transformer, and Switch 

These parts are located behind the control panel assembly on the right hand side of the oven.  
To access control panel, remove the vent knob and the seven screws around the outside of 
the control panel assembly.  Slowly pull the control panel toward you until the component is 
accessible. 

Thermostat 

Inside the oven, remove the fan baffle and the retaining clips holding the thermostat 
capillary tube to the inside of the oven.  Feed the bulb through the oven wall into the control 
panel area. Pull out control panel as previously outlined. Remove knob and two screws that 
hold the thermostat to the oven control panel. Remove the wires from the old thermostat and 
attach to the corresponding terminal of the new thermostat. Discard old thermostat.  
Reinstall the thermostat and capillary tube into oven and the control panel and restore power 
to the oven.  Test for proper operation. 

Contactor and Switch 

Pull out control panel as previously outlined.  Remove the wires from the contactor or 
switch being changed.  Place those wires on the corresponding terminal of the new contactor 
or switch.  Remove old contactor or switch and mount new contactor or switch with wires 
attached.  Discard old contactor or switch. Reinstall the control panel and restore power to 
the oven.  Test for proper operation. 

Transformer 

Pull out control panel as previously outlined.  Remove the wires from the old transformer.  
Place the wires on the corresponding terminal of the new transformer.  Remove old 
transformer and mount new transformer with wires attached.  Discard old transformer. 
Reinstall the control panel and restore power to the oven.  Test for proper operation. 

Blower Wheel 

Inside the oven, remove the racks and right hand rack slide.  Remove wing nut holding oven 
baffle.  Remove oven baffle exposing the blower wheel. Loosen the two 1/4-20-set screws 
holding the blower wheel to the motor shaft.  Using a three-fingered wheel puller, grasp the 
puller ring with all three fingers and tighten the puller until the blower wheel hub clears the 
motor shaft.  Place new blower-wheel on the motor shaft and position the new blower wheel 
so that it is flush with front inlet ring.  Tighten the set-screw over the flat spot on the motor 
shaft and spin the blower wheel to confirm that blower wheel is strait.  Adjust if necessary 
and tighten second set screw.  Test for proper operation.  

Motor  

Remove the blower wheel as outlined above.  Once blower wheel is removed, remove the 
six bolts holding the motor plate to the side wall of the oven.  Gently pull the motor out and 
lay on the bottom of the oven cavity.  Note each wire location on the motor and remove the 
wires.  Remove motor from cavity and remove old motor from motor mounting plate.  
Attach new motor to motor mounting plate.  Reverse removal instructions to assemble.  
Discard old motor and test for proper operation.
