T- 1.5.53 [TEMPERATURE] IS STABLE
WITHOUT LOOKING AWAY (to avoid damage), watch the external meter for up to twenty-five (25) minutes
or until if it exceeds 95° C! TWO (2) possible scenarios:
1)
IF (and ONLY if) the meter exceeds 95° C: See procedure number T- 1.5.677 (page 256).
2)
IF the meter does NOT exceed 95° C: Perform parts A THROUGH I below as prompted:
a) Remove the 80° C resistor plug from the distribution board.
b) Turn the machine off and replace
NTC #3
* with a known good, and plug it into the
2
nd
distribution
board position from the left, “MON-NTC”. * To LOCATE NTC #3 refer to Figure 42 (page 218)
c) Read before performing! Return to (ABOVE) procedure number T- 1.5.1 (page 247) to see if the
new NTC #3 fixed the problem. If (and ONLY if) you return to procedure number T- 1.5.53 continue
to part D.
d) Turn the machine off and swap in a known good Sensor Board* then continue to part E. *To
LOCATE the board refer to Figure 4A (page 9).
e) Perform TWO (2) calibrations: Cal 1) Temp Control; Cal 2) Cond Cells. After the calibrations
continue to part F.
f) Read before performing! Return to (ABOVE) procedure number T- 1.5.1 (page 247) to see if the
new Sensor board fixed the problem. If (and ONLY if) you return to procedure number
T- 1.5.53 continue to G.
g) Read before performing! Turn the machine off and swap in a known good Functional Board THEN
see part H.
h) Perform FOUR (4) calibrations: Cal 1) Voltage Detection; Cal 2) Temp Sensor; Cal 3) Temp
Control; Cal 4) Cond Cells. After the calibrations see part I.
i) Return to (ABOVE) procedure number T- 1.5.1 (page 247) to see if the new board fixed the
problem.
