Control
The operation of the oven is achieved by input
from the control to the thermostat. The control
receives power directly from the line cord. Power is
transferred via a N.C. relay to the thermostat at P7
black wire.
To access the control, slide the unit out 6 to 8
inches. Remove oven selector and thermostat
knobs, remove screws securing thermostat and
selector bezel, unscrew bezel for oven light switch,
remove button for oven light switch, remove clock
buttons, clock knob, remove screws securing upper
trim piece, screws securing control panel (two at
top and bottom and two on each side). With the
aid of a flat blade screwdriver, separate the control
panel from the inner control panel. Remove screws
securing control to inner control panel.
Note:
Open oven door, and place oven rack in
highest position, and slide rack out. This will serve
as a support for the control panel during testing
and prevent wires from pulling loose.
Control should have 120 VAC from terminals L1
(double black wire) to L2/neutral (double white
wire) and should supply 120 VAC to P7 black of
thermostat.
Electronic Thermostat
The thermostat controls the temperature to the
oven based on the input received from the RTD
and thermostat knob based on end users selection.
Once the input is received, the thermostat will
send 120 VAC via P7 red to the selector switch to
perform the appropriate action.
To access the thermostat, slide the unit out 6 to
8 inches. Remove oven selector and thermostat
knobs, remove screws securing thermostat and
selector bezel, unscrew bezel for oven light switch,
remove clock buttons, clock knob, remove screws
securing upper trim piece, remove screws securing
control panel (two at top and bottom). Remove
control panel and thermostat is accessible.
Note:
Open oven door, and place oven rack in
highest position, and slide rack out. This will serve
as a support for the control panel during testing
and prevent wires from pulling loose.
The thermostat receives supply power input at
P1, 120 VAC at P7 black, thermostat input at P6,
and oven temperature input at P5. The thermostat
sends output power to the selector switch via P7
red.
