16. Removal of Control Board
A. Disconnect the following connectors from the
control board:
(A) Main Wire Harness, Relay Board to Control
Board J2 (10-pin)
(B) Room Thermistor J4 (2-pin)
(C) Freeze Thermistor J1 (2-pin) with black tape
(D) Drain Tank Switch J5 (2-pin)
(E) Remote Control Sensor J12 (3-pin)
(F) Auxillary 2 / Jumper
NOTE: Mark each of the 2-pin connectors with a
different color marker to ensure the correct
orientation when they are reconnected or label all
2-pin connectors with tape. Label A thru D as
shown, then repeat for all wire sets.
17. Inspection of Capacitor (for Fan Motors and
Compressor)
Ohmeter Method - Set the ohmeter to the 100K Ω
range. Place the two probes against the tow
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.
18. Capacitance Tester Method
Using a capacitance tester and the chart on page
17, test the capacitor for the value indicated. If
the value tested is not within 10% of indicated
capacitance, replace the capacitor.

WARNING: 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.
19. Inspection of Drain Switch
Check for continuity between terminals 1 and 2.
Continuity should exist. With switch depressed,
no continuity should exist between terminals 1
and 2. If continuity is not as specified above,
replace the switch.
