Correlates LED flash counts with specific error descriptions and recommended diagnostic tests.
Lists common refrigerator problems with possible causes and corresponding diagnostic tests to perform.
Details fault codes (E1-E4), their meanings, and the specific troubleshooting steps or pages to refer to.
Tests DC supply voltage at the connector and terminals to ensure it stays within the operational range.
Checks if the exterior cooling fan is operating and measures DC voltage at the control module terminal.
Tests the motor start function by turning the unit off for five minutes, then back on to check for error codes.
Verifies input voltage, checks for unit overload, and assesses fan operation and coil cleanliness.
Tests the thermal protection of the control module, ensuring vents are clear, coils clean, fan operates, and temp is within limits.
Checks for disconnected wires, ON indicator light, DC power connection, and correct input voltage.
Checks thermistor connections, control board, magnet valve, and potential shorted wires.
