Re-seat connector
Replace sensor.
Go to next step
to test the board
as well before
replacing sensor.
Replace main
board. Replace
sensor as well if
resistance was
incorrect in the
previous step.
Re-seat and
re-check sensor
resistance with a
●
Replace sensor
Start
Is connector plugged in and
seated securely?
Disconnect power and un-plug senor
connector from the board.
Check resistance across the set of
wires for the faulting sensor. Does
the resistance correspond to the
temperature located in the respective
chart ? (See Reverse side.)
Reconnect sensor to the board and re-apply power.
Check voltage between the two corresponding
solder joints or through the top of the Molex
Is the voltage ~5VDC?
Is the temperature at the
sensor out of operating
range (+/- 3%)?
