TO CHECK CAPACITORS
1. Disconnect the cabinet from the power supply.
2. Make sure the capacitors are discharged before
touching terminal. (Shunt across the terminal of
capacitor with a heavy insulated wire.)
3. Remove the wires from the capacitors.
4. Any capacitor found to be bulging, leaking, or dam-
aged should be replaced.
5. Use a multimeter to check the run and start
capacitors for shorts or open circuits.
With a good capacitor, the indicator should first move
to a reading and then gradually increase to infinity.
If there is no reading change, an open circuit is indi-
cated.
If the multimeter remains on a low resistance reading,
a short circuit is indicated.
On run capacitor, touch probes to metal case and
each terminal. If meter show any reading, a ground
is indicated. All defective capacitors should be
replaced.
