Troubleshooting – Quick Reference
1. Check for supply voltage at rear of the refrigerator. Turn refrigerator ON. The
operating voltage should be between 10.5V and 32V DC. There will be some
variation in these readings depending on the supply voltage.
2. Check for voltage (15V – 25V AC) at compressor
between points A and B (See Figure 10). If voltage
is not within range, refer to Procedure C on page 5.
3. Take an Ohm reading (1.4 – 3.5
between points A and B (See Figure 11). If Ohm
reading is not within range, refer to Procedure B on
page 4.
4. Take an Amp reading (1.6 – 3.3 Amps) at the black
wire with the rubber boot (See Figure 12). If amperage is
not within range, refer to Procedure D on page 6.
