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
should show a reading of a few 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 should show
a reading between ten to twenty 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 should 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 should 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 should 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.
