Sail Switches (
Double and Single Wall Ovens
The left and right sail switches are normally
open limit switches located at the rear of the
component compartment in front of the
cooling fans.
The sail switches monitor the presence of the
airstream from the fans. If either fan (HVT fan
or right cooling fan) malfunctions, the
applicable sail switch opens and opens relay
R1, which disables power to the microwave
HVT and oven cooking elements. In addition, if
the right cooling fan malfunctions on the
double oven, the right sail switch opens and
opens relay R2, which disables the lower
oven cooking elements.
The relay coil resistance is approximately
920 Ω.
Left Sail Switch
Both R1 relay and R2 relay (double oven only)
are double pole single throw relays. Both
contacts are used on R1, only one contact is
used on R2.
