Thermostat
The thermostat is a potentiometer whose resistance
varies per user selections. The selected resistance
informs the control board of the user’s selection.
The table below on page 27 shows the
characteristics of the thermostat positions. All
values are approximate.
To access the thermostat, open oven door and
remove the screws securing the control panel,
remove control panel, the thermostat is now
accessible. Check the resistance and voltage per
chart on page 27, if the readings are within range
check the oven sensor resistance. If the readings of
the thermostat or sensor are out of range, replace
that component.
Selector
The selector is a potentiometer whose resistance
varies per user selections. The selected resistance
informs the control board of the user’s selection.
The table on page 27 shows the characteristics of the
selector positions. All values are approximate.
To access the selector, open oven door and remove
the screws securing the control panel, remove control
panel, the thermostat is now accessible. Check the
resistance and voltage per the chart on page 27, if
the readings are within range, check the oven sensor
resistance. If the readings of the thermostat or
sensor are out of range, replace that component.
Note: The thermostat and selector can be checked
from the control board assembly.
