1. Test Overloads – perform test for each overload. Verify the power is off before testing.
a. Overload identification
i. Left overload is "Run" or "Main."
ii. Right overload is "Start."
b. Push red reset button to verify closure. It may be necessary to press these buttons very hard to reset.
c. Set ohmmeter to lowest range.
d. Test resistance between the two soldered connections on the top of the overload.
e. If the resistance is less than 0.5 ohms, the overload is good.
f. If the resistance is greater than 0.5 ohms, replace both overloads.
2. Check the amps on the red wire from MCB.
a. This test requires careful attention. The amp readings may change within seconds.
b. Power off the control panel.
c. Attach the ammeter to the wire connected to the "RED" terminal of the MCB.
d. Power on the control panel.
e. If amps do not jump, go to "Test Capacitor" and check "Start" capacitors.
f. If amps jump and stay high, go to "Test Relay."
g. If amps jump and return to zero, go to "Test Capacitor" and check "Run" capacitors.
h. If amps jump and return to normal "Red" amps (see table below) the MCB is functioning correctly.
i. Normal Amp Readings

3. Test Capacitor. Verify the power is off before testing.
a. Capacitor Identification – usually "Start" capacitors are large and black and "Run" capacitors are small and silver.
b. Set ohmmeter to 20,000 ohms.
c. Remove all wires from one terminal of the capacitor.
d. Test resistance between the two terminals.
i. Resistance should climb towards infinity (open line). If testing the 5HP Start Capacitor, the resistance should climb to
15,000 ohms.
ii. If resistance does not climb, switch meter leads.
iii. If the resistance still does not climb, replace capacitor.
e. If the meter has capacitance checking capability, check the capacitance. See table below.
f. Reconnect the leads to the capacitor.
