Capacitor Test
1. Turn main power OFF . Disconnect power
supply.
2. Relieve pressure, page 23.
3. Locate the large, blue capacitor in the upper right
corner of the lower cabinet.
4. With a DC voltmeter, measure the voltage across
the capacitor terminals to verify that the voltage has
discharged to below 10 volts.
5. With an insulated handle screw driver, short across
the two contacts on the end of the capacitor to com-
plete discharging it. Hold for two seconds.
NOTE: A small spark may issue from the contact point.
6. Inspect the capacitor for irregularities such as
cracks, leakage, burn marks, or irregular shape.
7. Set an Ohmmeter to a range of at least 1K
Ω
and
connect the meter leads to the capacitor with the
red lead to the positive (+) terminal and the black
lead to the negative (-) terminal.
8. Observe the meter reading. It should start near 0
Ω
and climb up to 10K
Ω
, 20K
Ω
, etc., as the meter
battery charges the capacitor. This indicates a good
capacitor.
9. A reading of 0
Ω
(shorted) or O.L (open) indicates a
bad capacitor. In this case, replace the capacitor.
with the exact replacement part, item 76 on pages
55 and 56.
Circuit Breaker Module
1. Turn main power OFF . Disconnect power
supply. Turn circuit breakers on to test.
2. Relieve pressure, page 23.
3. Using an ohmmeter, check for continuity across cir-
cuit breaker (top to bottom). If no continuity, trip
breaker, reset, and retest. If still no continuity,
replace breaker as follows:
a. Refer to electrical diagrams and to T
ABLE
2. Dis-
connect wires and remove bad breaker.
b. Install new breaker and reconnect wires.
* Depending on model.
