Easy Fix For EH 00 EC 51-52-53 Error Code In Mini Split AC

this mini split air conditioner circuit first  error on display shows an eh00 error code   through these error codes, the unit tries to tell  you the actual fault of the unit, if you do not   know the meaning of these particular error  codes. It will be tough for you to solve the   unit's problem. For this purpose, you first need  to recognize the PCB, the best way to recognize   the circuit board is through its manufacturing  code number this helps you find the PCB type   and Manufacturing details this is the indoor  unit's PCB code number pause the video and you   can easily read the number of pcbs the outdoor  units PCB code number is this eh is the indoor   unit error most indoor units have flash memory  systems technically we call it eom and it stands   for electrically erasable programmable readon  memory this is the flash memory installed here   in the PCB suppose it is corrupted internally or  physically damaged or short-circuited or does not   have the operating voltages to operate it in that  case an e00 error can be displayed on the indoor   unit you should have a multimeter and set it on  the DC voltages attach the main Electric Supply   to the PCB and you should check the voltages on  the eom through which you can find the fault or   you can even decide the next move to repair  the circuit board for this purpose check the   four number pin which is the ground pin but here  all four pins are attached and grounded although   one two or three are address function pins but  here they are joined together now we switch on   the PCB all these pins are joined Direct ly and we  keep the multimeter probe here put the multimeter   another Probe on pin 8 and as you can see 4.46  DC volts are present on both pins it means its   operating volts are available if you find the  correct operating voltages on the pins besides   this if you still have a problem with the e00  error you must change the eom directly but before   changing the IC you should have to reprogram the  particular IC you should already have its correct   program program the new eom and replace it with  the old one the circuit board will start to work   and the eh0 error code will vanish the next error  that is shown on the display is EC 53 let me tell   you about this error as well during this error  the indoor circuit is working the compressor has   also started to work it has no issue the error  is still displayed the LED light on the outdoor   circuit board is blinking rapidly which means  that the circuit board has a problem the outdoor   circuit board sensor with a white connector which  is used to check the ambient temperature if this   sensor is missing from the circuit board or is  short circuited then this EC 53 error will be   shown on the display of your mini split air  conditioner now the display is showing an EC   51 error code this error is not of the indoor  circuit but of the outdoor circuit board when   this eom of the outdoor unit gets corrupted or  short circuited then this error will be displayed   on the display I will check the operating voltages  on this IC if the operating voltages are missing   then it means that something else in the circuit  board is faulty I have passed electricity through   the circuit board the circuit board has powered  on I will put the multimeter black Probe on the   four number pin of the IC which is the ground pin  and the red Probe on pin number eight 5 volts are   passed through this IC the required operating  voltages are passing through the IC this means   that the eom is short circuited internally I  will install a new eom we should have already   programmed the new eom with the same data as the  old eom this error will be fixed when the new eom   with the same data is installed the next error  is EC 52 the compressor has started to work the   error is still displaying despite the compressor  being turned on I have turned off the display from   the remote because on the outdoor circuit board  the heat sync is not installed so my compulsion   was to turn off the display this error code  is also for the outdoor unit the LED number   101 in the circuit board is blinking rapidly  which means that the error is present in the   circuit board the sensor of the black connector  is not installed on the circuit board the black   connector has a pipe coil sensor attached to it  which is installed on the condenser of the air   conditioner if the sensor short circuits then  this error code EC 52 is displayed on the air   conditioner this is how you can fix these error  codes join the membership to support the channel   on patreon click on the left or right thumbnail  to watch the next videos and subscribe thank you
