Integrated Control Diagnostic Codes (continued)
E 406 | LSOM − Compressor open start circuit. | Required amount of current is not passing through |
|
| Start current transformer. Clears the error after cur- |
|
| rent is sensed in START sensor, or after power re- |
|
| set. |
|
|
|
E 407 | LSOM − Compressor open run circuit. | Required amount of current is not passing through |
|
| Run current transformer. Clears the error after cur- |
|
| rent is sensed in RUN sensor, or 1 normal compres- |
|
| sor run cycle, or after power reset. |
|
|
|
E 408 | LSOM − Compressor contactor is welded. | Compressor runs continuously. Clears the error |
|
| after 1 normal compressor run cycle or after power |
|
| reset. |
|
|
|
E 409 | LSOM − Compressor low voltage. | Secondary voltage is below 18VAC. After 10 min- |
|
| utes, operation is discontinued. Clears the code |
|
| after voltage is higher than 20 VAC for 2 seconds or |
|
| after power reset. |
