What actions are required if the LD301 LED persists in blinking after a self-check?

The necessary action depends on the fault code indicated by the number of blinks. If checking or replacing the specific faulty component (such as the ISPM, compressor, or probe) does not stop the blinking, the main circuit board must be replaced. For EEPROM errors, a replacement of the main board is required immediately.

What should be done if LED 301 continues to flash after a self-check?

The action depends on the error code determined by the number of flashes: for power failure (block 4), check the main board; for low rotation speed (block 6), replace the ISPM board, compressor, or main board; for sensor issues (block 15), replace the sensor or main board; for EEPROM errors (block 13), replace the main board.

How to troubleshoot a continuous LD301 LED blinking during a self-check?

The procedure depends on the number of blinks: for a power cut (4 blinks), check the main board; for low rotation speed (6 blinks) or probe issues (15 blinks), replace the main board if initial component replacements do not resolve the fault; for an EEPROM error (13 blinks), the main board must be replaced.

What procedure should be followed if LED 301 continues to flash during a self-check?

The resolution depends on the number of flashes: for power failure (4 flashes) or low rotation speed (6 flashes), check or replace the main board; for sensor issues (15 flashes) or EEPROM errors (13 flashes), replace the sensor or the main board as specified.
