Troubleshooting the E5 Error Code: Expert Tips for Mini Split AC Owners

you can see this mini split air conditioner is  showing an E5 error code I will tell you the   E5 error code solution in detail this is the  indoor model number of this air conditioner   and this is the Outdoor model number  which you can see on the screen   this is the Outdoor of this inverter air  conditioner when the E5 error is shown on   the display of your inverter air conditioner  the indoor blower motor will keep working fine   but it will not do Cooling the E5 error code means  that this is a Serial communication error but in   the normal sense we can say that when the indoor  and outdoor is not able to talk to each other or   cannot understand each other's language to check  the error code I will test the most simple things   by testing those you can save money and time  easily the cables are attached between the indoor   and the outdoor if any wires between them are  loose connection they will work fine for some time   but when the wire sparked due to loose  connection rust will be made inside the connector   or carbon is made due to sparking if the error is  shown due to the wires being loose connection then   check the wires if the wires are disconnected  from any point it will still show an E5 error   This indoor air conditioner's Main  Electric Supply is from the indoor unit   then the indoor supplies power to the outdoor  unit use a tester to check the wire with the   line connector if the light glows on the tester  then it means the electricity is passing fine   other than this use a Multimeter to check whether  electricity is passing towards the outdoor unit   if the electricity is passing from the indoor then  check the outdoor as well if the electricity is   passing through the indoor and is being shown on  the multimeter then you can easily know that the   electricity is passing towards the outdoor if  the electricity is not passing from the indoor   unit so let me show you by opening its cover that  what the problem could be I have experienced that   most of the time the outdoor unit gets faulty  I am opening the cover of the control board   when the outdoor units control board goes bad for  any reason then the E5 error code is also shown   so normally you have first to check its fuse if  the fuse due to any reason Burns then the E5 error   code will be shown on the display of the inverter  air conditioner this is the fuse that could be   burned but if the fuse is not burned then check  the communication circuit if the communication   circuit is faulty this problem will still be shown  both in the outdoor and indoor circuits I have   removed the cover from the indoor unit now I will  remove the control board out from the indoor unit   I have removed the control board from its  body the indoor unit has this switching   relay installed in it this relay is of 30 amperes  and works on 220 volts suppose it gets bad as the   microcontroller has turned it on the pins inside  the relay joins when energized with 220 volts   so if carbon is made on the pins of the relay  which will not let make contact between the pins   and the electricity will not pass further I  have experienced that when high volts pass   across the indoor unit the s-wire Burns  in spite of being a good quality wire   low voltages are communicating between the indoor  and the outdoor that is why the signals do not   pass if the wire is burned the wire still shows  continuity well on the multimeter attach another   wire with the signal connector and if the error  does not show then it means the wire is not fine   so replace the wire with the new  one and the problem will be finished   click on the left or right thumbnail to watch  the next videos And subscribe it's free thank you
