WARNING
Selector Switch
The oven selector switch is used to switch the clock/
timer to control either the upper or lower oven during
automatic and timed and self-clean operations or to
set both ovens for manual operation.
The switch positions are:
Manual (both ovens)
Upper Timed
Lower Timed
Upper Clean
Lower Clean
Use the following procedure to check selector switch
contacts for continuity.
1. Disconnect power from range.
2. Access contacts by removing control panel glass
and mounting bracket.
3. Remove selector switch wiring.
4. Check selector switch contacts by setting an ohm-
meter in the low ohm range. See selector switch
position table below.

Sail Switch

The sail switches are located in the rear of the control
compartment and mounted to the control compartment
back, in front of the fan motors. During self-clean op-
erations, the selector switch contacts 14-11 or 14-12
close, supplying power to the fan motors. The air from
the fan motor pushes against the sail switch paddle,
closing the sail switch contacts, supplying power to the
self-clean circuit. The sail switch contacts must close
for proper self-clean operation.
Use the following procedure to check sail switch con-
tacts for continuity.
1. Disconnect power from range. Disconnect switch
wiring.
2. Access sail switches by removing oven from cabi-
net and removing oven cabinet top.
3. Set ohmmeter in the low ohm range. Attach meter
leads to switch terminals.
4. Meter should indicate no continuity or infinite ohms
when switch is in normal open position.
5. Push on switch paddle to close switch contacts.
Meter should indicate continuity or a low ohm read-
ing.
6. Check both sail switches. Replace sail switches
which fail test.
Important Note: Both sail switches must be tested.
