v. Press the “ ” icon to display current temp.
vi. Press the “+” icon to turn on the Compressor and fans (note that when the board is sending a signal to
the compressor, there is a dot on the 7 segment LED that illuminates, almost like a decimal dot after the
2nd character. This is also true for regular operation, not just test mode).
vii. Pressing the “-” icon you can turn them off.
vi. You can toggle between compressor (and fans) on and off by pressing “+” or “-” depending on which
state it is in.
vii. Verify that the Evaporator Fan and the Condenser Fan is coming on when you turn it on and turning off
when you turn it off.
viii. Verify that the compressor is turning on and off. There will be a slight vibration that can be felt by placing
your hand on the lower bottom side wall of the fridge.
ix. Then take an amp drawn reading from the power supply using a clamp meter around the live wire at the
plug(brown). If the compressor is turning on, the current drawn will be between 0.3Amps to 1.2Amps:
i. If the Amperage reading is less than 0.5Amps, the fridge is low on refrigerant and needs to be replaced.
In this situation, return the unit and request a replacement unit. See Figure 85.
ii. If the Amperage is higher than 1.2Amps after approximately 5minutes of operation, there is a restriction
in the refrigerant line and needs to be replaced. In this situation, return the unit and request a
replacement unit. See Figure 85.
c. To exit this mode, you need to cut power to the unit.
d. Additional troubleshooting can be found in Appendix I: Fridge Functionality, Maintenance, and
Troubleshooting Guide.
Symptom 11: Fridge Light OFF:
1. Screen on Off Mode:
