Re: Error messages

Full of water in lower tray. Normally it takes care of moister but in extreme humidity it may be necessary to manually empty the unit.

Re: Error messages

Emptying water from drain plug took care of the e7 error then then unit went back to normal.

Code error E7

I'm not sure if NewAir is made by Gree -- they supply many. On Gree units, E7 simply means one unit is requesting heating while another is requesting cooling and you can't have both at the same time. So that's the first thing to check. Very simple, very common, doesn't indicate that anything is wrong with the system.

Hi,I am really hoping to find someone to help me if possible. I have a one year old carrier infinity 4ton 17seer condenser and a 5ton variable speed air handler. I has worked fine but now i am getting a...

If this si what I am thinking it is, it will be very hard to find and prove....
The compressor windings have aflat spot and if the motor stops at the right place it will not atart. The voltage goes way up and kicks out the thermal over load and gives you the alarms that you are getting.
The motor cools down and you reset the unit, the motor has moved just a tick trying to start the last time so now it is off of the bad start spot and will take off and run till it stops at the bad spot again....
Did that make any sense???
Long story short your compressor is going bad...problem will be to get it changed under waranty and convincing the installing company that you have a problem that requires a compressor replacement...
See if you can get them on a short leash and have them come before you reset the alarms and hopefully maybe they can catch what it is doing...
This is and will be a tough one... I've been there with a customer or two already... no fun... trying to figure things like this out!

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

I have an 18 K unit with E7 error on heat mode

I just installed a YMGI brand mini-split AC and had exactly the same problem. AC worked fine, but when I tried using heat mode I would get an E7 error.

After talking to their tech support I discovered the problem. There was a separate cable that needed to be connected that I'd forgotten to hook up. This cable runs from the internal unit to the outdoor unit and connects a defrost sensor.

In my case I had totally missed that cable when I installed the unit. After running another line and connecting it the unit is now functioning normally.

If this is a new install, then make sure all your cables have been run. If it was previously working, then check to see if one of the cables had become disconnected. If it's not the cable, then it's probably the sensor.

Good luck
