I recently had the E2 error code on 2 units a KFR-35GW/BMVE and KFR-50GW/BMVE. I recommend checking the refrigerant. Our's was extremely low and having it filled/charged resolved the issue. In all of the Googling, this solution never came up.
Initially the error code would come on and flipping the breaker off for 10 mins or so would reset it and it would work. Probably did this about 10 times every so often (like over weeks). Eventually this did not work and researching online led us to believe that either the indoor pipe sensor or indoor PCB was bad. Spent lots of time online trying to find these replacement parts to no avail. Was finally able to get a friend of a friend that is an A/C person to check them out and discovered the Freon was too low. Hope this helps someone else out there stuck with these "unserviceable" units.
Wow! I hope you are right. I have been getting that code also and trying to find parts all over the place! I doubt it will work in the long run, as I have gotten the error in the winter also, so don't think refrigerant will help that.
