4. TROUBLESHOOTING
4-2-15) Troubleshooting based on LED Blinking Frequency
When the Failure Condition occurs, the Compressor will immediately stop if the Compressor is running and there will
be a 5 minute standby. During the 5 minute standby, RPM signals will be ignored.
That is, even though the Inverter PCB receives the RPM signals, the Compressor does not work.
It blinks every second and there is 2 second off at the end of each cycle.
Description LED Blinking Frequency Remark
Normal Operation N/A
Failure Check if there is any short between Comp terminals.
IPM Fault
Check IPM Voltage [lower than 13.5V].
Check any short between IPM Pins [#1~33].
Location Detect
Failure
Check Comp and Cycle.
Check the continuity of the following resistances for
Short/Open (R505, R506, R507, R508, R509, R510,
R511, R512, R513) Check Comp. Connector.
Motor Restriction
Check Comp and Cycle.
Check the continuity of the following resistances for
Short/Open (R505, R506, R507, R508, R509, R510,
R511, R512, R513) Check Comp and Cycle.
Low Voltage
When the Input Voltage is under AC110V Check the
continuity of R517 for Short/Open
Over Voltage
When the Input Voltage is higher than AC300V,
check the continuity of R514, R515 and R516 for
Short/Open
