288.1 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 breakdown.• Protection codes shown with LED on the outdoor unit do not indicate a malfunction; these are codes showing that the producthas 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 constantfrequency 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 cannotsolve 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 problemsmore easily and faster and take action, to transfer more accurate information to the service providers, and to process invoicesproperly, please make sure that the malfunction descriptions are understandable, informative and appropriate. If necessary, takephotographs 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 theinformation regarding the place of the repair must be written, and photographs must be included when necessary. The partrepaired, 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.8.2 Error CodesERROR Indoor UnitDisplay Outdoor Unit LEDCompressor cable disconnected / Sw compressor incompatibility ER 02 Blinking 25 times - stopping for 3 sec.Indoor unit pipe sensor is on or short circuited ER 03 No displayIndoor unit fan motor error ER 04 No displayIndoor unit setting not performed/deleted ER 05 No displayIndoor and outdoor unit communication error ER 06 Blinking 9 times - stopping for 3 sec.Gas leak error ER 07 Blinking 7 times - stopping for 3 sec.Current protection/sudden disconnection in supply No display Blinking 8 times - stopping for 3 sec.Model incompatibility between units ER 09 Blinking 22 times - stopping for 3 sec.Board cooling sensor is on or short circuited ER 10 Blinking 15 times - stopping for 3 sec.Compressor start protection ER 11 Blinking 11 times - stopping for 3 sec.Compressor over current protection (if it occurs during operation) ER 13 Blinking 13 times - stopping for 3 sec.Compressor over current protection (if it occurs during first start) ER 14 Blinking 8/13 times - stopping for 3 sec.Outdoor environmental sensor is on or short circuited ER 15 Blinking 16 times - stopping for 3 sec.Compressor pressing sensor is on or short circuited ER 16 Blinking 17 times - stopping for 3 sec.Outdoor unit setting not performed/deleted ER 18 No displayHigh voltage error during startup (card or reactor sourced) ER 17 No displayLow/high voltage protection HL Blinking 18 times - stopping for 3 sec.Compressor discharge temperature is too high product stopped(protection) No display Blinking 19 times - stopping for 3 sec.AC high voltage information No display Blinking 20 times - stopping for 3 sec.Board cooler temperature is too high, product stopped (protection) No display Blinking 21 times - stopping for 3 sec.Arc protection (loose connections) AE Blinking 24 times - stopping for 3 sec.Outdoor unit BLDC fan motor error ER26 Blinking 26 times - stopping for 3 sec. |
