Code P8 showing on remote controller #PAR-JC240KUS for indoor unit # PL12FK

What causes the P8 error code? As we mentioned above, the P8 fault can mean many things when it pops up on your Mitsubishi Electric wall controller. The P8 fault is activated when the indoor coil sensor does not change the temperature for a set amount of time after the compressor is (or should be) switched

P8-Abnormality in outdoor unit.

Solution:
1) Check the indoor/outdoor connecting wire in proper point.
2) Change the connection of electric wiring, if reversed phase.
3) Check the protection device, if malfunction, replace it.
4) Measure the resistance of the outdoor coil thermistor.
If the resistance is normal, replace the
outdoor controller board

Code P8
Error detail Abnormality of pipe temperature. Due to less pumping in compressor or short of gas.

if split ac display shows e3 what is the solution for that problem

8 flash is a pipe temperature error.

The units were set up as master/slave by removing a jumper on the indoor board of the 0V unit. The CENTRALISED CONTROLLER display was removed by changing one of the indoor boards dipswitch settings.

P8 error is abnormal pipe temperature indoor. If you are running it on heating P8 error will appear because the disc pressure is too high. It could be overcharged.
