J. Remove the five (5) screws from the control
board on the control panel assembly. Remove
the control board.
11. Inspection of Capacitor (Fan Motor and
Compressor)
Ohmeter Method – Set the ohmeter to the 100K
Ω
range. Place the two probes against the two
terminals of the capacitor. At first, the ohmeter
should indicate 0
Ω , then the reading should
gradually increase towards infinity ( ∞ ). This
indicates that the capacitor is charging. If the
reading indicates infinity right away (shorted) or
the ohmeter fails to move from 0
Ω (open), replace
the capacitor.
12. Capacitance Tester Method
Using a capacitance tester and the chart on page
15, test the capacitor for the value indicated. If
the value tested is not within 10% of indicated
capacitance, replace the capacitor.
ƽWarning: Properly discharge the capacitor(s)
before testing and after testing has been com-
pleted. Failure to do so could cause damage to
test equipment or the unit and/or result in per-
sonal injury (electrical shock) or death.
