2.Thermal Overload Protector

3.Overload Protector Retainer

4.Compressor Terminal Cover

5.Terminal Cover Retainer

6.Compressor Run Capacitor

Test Procedures:

WARNING: The compressor start capacitor must be properly discharged before proceeding. This is most commonly done on low voltage capacitors by shorting across the terminals with a screwdriver.

Compressor Start Relay: Refer to FIG. 20

1.Disconnect the dispenser from the power source.

2.Remove compressor terminal cover retainer (5) and compressor terminal cover (4).

3.Connect a voltmeter across the white wire and the white/ orange wire. Connect the dispenser to the power source. Verify the dispenser is in “ICE” or “CHILL” mode.

The indication must be:

(a)120 volts ac for two wire 120 volt models or

(b)230 volts ac for two wire 230 volt models.

5.Disconnect the dispenser from the power source.

If voltage is present as described, proceed to the following test procedures.

If voltage is not present as described, refer to the Relay and check the relay.

6.Disconnect the two black wires from the compressor start relay.

7.Remove relay from the compressor.

8.Check for continuity across the upper left terminal and the right pin socket on the rear of the relay.

If continuity is present as described, the compressor start relay is operating properly.

If continuity is not present as described, replace relay.

Compressor:

1.With the compressor start relay (1) removed, disconnect the black wire from the compressor.

2.Check for continuity across the terminal on the compres-

sor and the left pin on the compressor.

If continuity is present as described, the electrical part of the compressor is operating properly.

If continuity is not present as described, replace the com- pressor.

Thermal Overload Protector:

1.Check for continuity across the terminals on the thermal overload protector (2).

If continuity is present as described, the thermal overload protector is operating properly.

If continuity is not present as described, replace the thermal overload protector.
