Need help with error codes on your Gree AC? Please leave a question below and we will be happy to help.

The type of refrigerant will be marked on the outdoor unit rating plate. It will probably be R22 or R410A. The amount of refrigerant will also be written on the plate. The entire system will require evacuation and leak testing. This should only be done by a Licensed Technician.

Typically the M# has the identification on if the unit uses R22 or R410. Look at the data plate. Or get the M# S#

What type of refrigerant? R22- 70psi is good/ r410- 70 psi not good. What is the head pressure, is the filter clean, is the coil frozen, is the fan operating properly, all the supply air grills open...lots of things cause funky pressures. Need more info

Display = E2
Malfunction or Protection = Communication error between indoor units and outdoor unit.

This is the meaning of the error code. If you need any more AC Cleaning & Repair help contact the professionals.

On the data plate for the outdoor unit it will tell you what type and how much refrigerant you need. If the line set is longer than 25 feet you will likely need a bit more than what it says. A 40 degrees evaporator temperature is ideal, approximately 65 psi for r22

USUALLY its R22. DO NOT USE ANY REFRIGERANT TIL YOU KNOW IT NEEDS IT THOUGH. The plate is usually inside the top cover and you can read it after removing the cover. If its a 110or 220 AC unit Im almost sure its R22. And the weight listed will be the most you should try to put in it. BUT before you do that you have to put on a piercing valve. And the pressures are higher for R22 than R134A. It will ofcourse depend on the outdoor and indoor temps as to what pressures youll be running as well as fan speed. Freezing is 57-58psig on R22 so the pressure after ruinnign 10 to 15 minutes has to be greater than 57 or 58 PSIG. It is normal for some units to run for a while at a lower pressure when 1st started though so dont jump the gun.

If this is a outdoor unit, and the temp gets below 36F this will always happen, unfortunatley. check the connection of the E2 temp sensor. Maybe its broke inside.

Just had the same E2 come up on my HSU-445. The only thing we could figure out was to try a different tape than the one that was in there when the error came up. That seemed to do the trick. Not sure how long that will work. Good luck.
