DIAGNOSTIC MODE ERROR CODE CHART
| Number of Flashes | Diagnostic Error Code | Diagnostic Error Code Description |
|---|---|---|
| 1 | Battery protection cutout | The voltage level at the refrigerator 12 volt connector is below the parameter settings. This code may set when the refrigerator has been active with the engine off. |
| 2 | Fan overcurrent cut-out | The fan loads the electronic unit with more than 1 amp peak. Refer to INSPECTION AND VERIFICATION . |
| 3 | Motor start error | The rotor is blocked or the differential pressure in the unit is too high. This may occur in high ambient temperature situations or if the refrigerator was stopped and restarted within a short period at a high load and/or a high ambient temperature condition. Let the differential pressure lower before attempting to restart the refrigerator. |
| 4 | Minimum motor speed error | The refrigeration system is so heavily loaded by ambient temperatures that the motor cannot maintain a minimum speed of 1,850 RPM. Let the refrigerator system cool down before attempting to restart the refrigerator. |
| 5 | Thermal cut-out of electrical unit | The refrigerator is so heavily loaded by ambient temperatures that the refrigerator module gets too hot. Check the vents and the area of the compressor, condenser for a blockage, possibly from dust. Check the fan for correct operation. |
