3. Set the voltmeter to the AC 200 scale.

4. Touch and hold one voltmeter probe to one of the wire terminals, then

touch and hold the other probe to the other wire terminal

5. The voltmeter shall show a reading of 115 volts.

C. Output Live Voltage

1. In order to test the output of the electronic controller, the WINEMATE

cooling unit must be plugged in and powered up.

2. The input voltage must read at least 115 volts.

3. Set the temperature 5° F above the ambient temperature.

4. Set the voltmeter to the AC 200 scale, and the voltmeter shall read 0 volts.

5. Now warm the thermistor by hands for a while.

6. Locate the black and white wires leaving from the electronic controller.

7. Touch and hold one voltmeter probe to the black wire, then touch the

other probe to the white wire.

8. Now the voltmeter shall read 115 volts.

9. If the readings are both correct the electronic controller is good.

6) Thermistor

1. Disconnect the thermistor connector from the electronic controller.

2. Set ohmmeter to the R x 10K scale.

3. Immerse the tip of the thermistor into ice water for five minutes

4. Touch the ohmmeter probes to the wire terminals on the connector. The

meter shall indicate 27 ± 10%.

5. Reconnect the thermistor.

7) Fan Motors

The WINEMATE 1500 & 2500 uses four fan motors to pull air across the

condenser and evaporator coils. The safest way to check one of the motors is

doing a resistance check. An alternate method is checking with live voltage.

A. Resistance

1. Unplug WINEMATE cooling unit or disconnect power.

2. Disconnect the fan motor wiring from the terminal block, remove one wire

at a time, and carefully label each wire.

3. Set the ohmmeter scale to the lowest setting. Touch and hold one

ohmmeter probe to one of the wire terminals, then touch and hold the

other probe to the other wire.

4. The ohmmeter shall show a reading of 50 ohms ± 10%.

5. Reconnect the wires to the proper terminals as previously marked.

B. Live voltage
