CONTROL BOX CHECKING PROCEDURE:
Hazardous voltage. Can shock,
burn, or cause death. Disconnect power to
control box before doing these check
procedures.
A. General Procedures. (Power to control box
disconnected)
1. Disconnect line.
2. Inspect for damaged or burned parts, loose
connections, etc.
3. Check for misconnections against diagram
in control box.
4. If box is too hot, circuit breakers may trip
or fuses blow. Ventilate or shade box.
Move away from heat source.
5. If problem has not been found, check
motor and control box. Use test
procedures that follow.
B. Ground (Insulation Resistance) Test. (Power
to control box disconnected)
1. Ohmmeter Setting: Highest scale (usually
Rx100K or Rx10,000).
2. Terminal Connections: One ohmmeter lead
to "Ground" screw on control box and
touch other lead to each of the terminals
on terminal board.
3. Ohmmeter Reading: Pointer should remain
at infinity (∞) and not deflect.

C. Capacitor Tests. (Power to control box
disconnected)
Risk of electric shock. Short
capacitor across terminals before testing.
1. Ohmmeter Setting: Rx1000.
2. Terminal Connections: Connect ohmmeter
leads to black and orange wires out of
capacitor case.
3. Ohmmeter Reading: Pointer should swing
toward "zero" and "float" back to (∞).
Capacitor is shorted if pointer does not
move back to (∞), open if it does not move
from (∞).
4. To reset capacitor, reverse ohmmeter
connection to capacitor terminals.
