Checking procedure for main parts
SMGB0066 rev.0 - 12/2009
Measurement procedure
1.
Remove the fan motor connector from the control PCB, ISPM or
DIP-IPM.
2.
Connect the black test lead of the tester to the black wire pin of
the fan motor connector
3.
Connect the red test lead to the wire connector pin to be checked
Results
Normal:
Observed values will be close to the normal values in the table
below
Faulty:
Observed values will be deviated from the normal values in the
table below.
Generaly an open-circuit fault shows ∞, and a short-circuit fault
shows several Ω-kΩ.)
Internal electronic circuit fault of the fan motor including short-circuit and breakage can be checked.

(*) Values are shown for referenctial purpose. While actual values may vary depending on the type of the tester; any tester can be
used to determine any short-circuit or breakage based on ∞ or several Ω/several kΩ or 0Ω.
