Turn the machine OFF!!
b) Per the Figure right, place the
274 Ω
plug, from the
TWO-RESISTOR
SET
, into the
1
st
distribution board
position from the left, “CON-NTC”.
c)
Set your volt meter to measure resistance (Ω)!
d)
ENSURE the black lead remains attached to chassis ground (see
page 4)!
below, measure at the solder side of SENSOR BOARD’S ‘X2’ connector at

f)
Figure right, reading the meter’s numeric AND
units display, TWO (2) possible scenarios:
1)
IF (and ONLY if) LESS THAN 300
Ω (0.300 KΩ):
ENSURING the machine was OFF before
measuring AND assuming all procedures were performed correctly the mother board may be bad.
2) IF more than 300
Ω:
See parts a THROUGH d below:
a) ENSURE the machine was OFF prior to the measurement!
b) ENSURE the
274 Ω
plug, from the
TWO-RESISTOR SET
, is placed properly in the
1
st
distribution board positon from the left, “CON-NTC”! If not, repeat procedure number
c) ENSURE the meter was set to measure resistance (
Ω
) AND its go=round lead is at chassis! If
(page 291).
d) TWO (2) possible bad components: 1) Sensor Board
*
cable OR; 2) Distribution board. *
NOTE:
The Sensor Board cable can be checked!
NOTE
that one (1)
