Figure 27: Replacing a Sensor

CAUTION: When replacing a sensor, verify that the sensor is properly

S sensors have alignment slots which match up with

alignment tabs in the sockets. The combustible sensors each

have two non-polarized contacts which must line up with the

contacts in their socket. Forcing a sensor into its socket may

damage the sensor or the socket.
