Check the status LED on the board. If the LED is off and not blinking the compressor is operating normal

In order to determine whether the compressor is operating normally, check the output voltage during the refrigeration cycle. After initial power-up, when the compressor begins to operate, wait 10 minutes before checking. The compressor is operating normally if the voltage is greater than 80 Volts.
