Mini split units are nice to have and usually very reliable heating and cooling units.
Unfortunately, errors can happen, which is usually displayed on the indoor wall unit.
This error can be looked up in a manual to see what the meaning is.
For example, an E1 error code on a Pioneer Mini Split means there is a problem with the Indoor/Outdoor unit’s communication.
Often error codes can be manufacturer-specific, and sometimes, different models can have different errors codes.
The best way to troubleshoot any code is to have the manual for your unit.
Sometimes finding a manual can be difficult, so here we list the known error codes for big-name mini split manufacturers.
Keep in mind that there may be differences between models, but most of the codes should match.

My Pioneer Mini Split 9000 BTU is beeping every ten seconds or so and showing 88 and the WiFi signal. Not sure what code that is as it is not on the list. Any help or info would be appreciated
My air temp shuts down 6-8 times in 24 hr period, power light comes on temperature stays light up but 3 mins later it comes back on as normal. It only started since I turned on the heat and only use to be once a day but now it’s 6-8 times a day or every 3-4 hrs.
you might want to check the batteries on your remote. Highest temp read is 88 degrees. Seems your remote is stuck on 88 for that reason? just guessing…
I have a Carrier unit giving me an L3 code – don’t see it listed above. Any ideas what might be going wrong? It’s not heating…
I have a d2 code and I can’t find the error answer
I have a d2 code too on my pioneer split unit and cannot find out what it means. I spoke with a technician who told me he doesn’t know either. Did you happen to find out what it means?
I also have this same d2 code on mine. Did you ever figure out what it means?
