Important Information On Malfunction Procedures
• Boards should not be replaced due to ER-05, ER-07, ER-03, ER-15, ER-16, AE error codes.
•
Please make sure that you do not replace the sensor without seeing an error code. Sensors on inverter products rarely break
down.
•
Protection codes shown with LED on the outdoor unit do not indicate a malfunction; these are codes showing that the product
has entered the protection mode due to environmental conditions and external factors. When the conditions go back to normal,
the protection status of the product will also go away.
• The compressor does not operate by continuously increasing or decreasing its frequency. (For example, it rotates at a constant
frequency when the room temperature is equal to the set temperature.) Such situations should not be regarded as errors
• In the event of an ER-06 malfunction, first, apply the checking steps specified in the troubleshooting flow chart. If you cannot
solve the problem, finally perform the self-testing procedure.
• ,Each malfunction record entered can be seen by the technical personnel performing field track. In order to diagnose problems
more easily and faster and take action, to transfer more accurate information to the service providers, and to process invoices
properly, please make sure that the malfunction descriptions are understandable, informative and appropriate. If necessary, take
photographs and videos and include them in the records.
• Descriptions such as “Gas charge performed, problem solved.” are not enough. Leakage check must be performed, and the
information regarding the place of the repair must be written, and photographs must be included when necessary. The part
repaired, such as “compressor, 4-way valve, condenser, etc.” must be entered correctly.
•
Remember to specify the error code received in case of electronic board replacement.
