A. Resistance
1. Unplug WINEMATE cooling unit or disconnect power.
2. Remove the terminal cover from the compressor.
3. Remove the start relay and overload protector from the compressor. If
wiring is removed from the start relay and/or overload protector, carefully
label each wire according to its proper location.
4. Set the ohmmeter scale to the lowest setting.
5. Touch and hold one ohmmeter probe to the C (common) terminal, then
touch and hold the other probe to the R (Run) terminal. The ohmmeter
shall show a reading of 0.5-1.5 ohms. If not, the compressor is bad.
6. Touch and hold one ohmmeter probe to the C terminal, then touch and
hold the other probe to the S (Start) terminal. The ohmmeter shall show a
reading of 2.5-7.5 ohms. If not, the compressor is bad.
7. Touch and hold one ohmmeter probe to the R terminal, then touch and
hold the other probe to the S terminal. The ohmmeter shall show a reading
of sum of the last two measurements. If not, the compressor is bad.
8. Touch and hold one ohmmeter probe to the C, or R or S terminal, then
touch and hold the other probe to the ground on the compressor. The
ohmmeter shall read infinity. Any resistance indicates a shorted
compressor.
9. If the compressor tests ok, but does not start, check start relay, overload
protector and live voltage.
B. Live Voltage
1. Unplug WINEMATE cooling unit or disconnect power.
2. Remove the terminal cover from the compressor
3. The WINEMATE unit needs to be plugged in and turned on.
4. Locate the terminals on the start relay and the overload protector.
5. Set the voltmeter to the AC 200 scale.
6. Touch and hold one voltmeter probe to the terminal on the start relay, then
touch and hold the other probe to the terminal on the overload protector.
7. The voltmeter shall show a reading of 115 volts.
8. If the test is good and the compressor does not start, check the start relay,
overload protector, and measure the resistance.
