I bought a house with one already installed. Found that it isn't switching from 'hot' to 'cold' After time the unit will beep and flash LED's on the unit itself and then switch off. Rather handy on 40 degree days. Good luck sourcing parts for the unit as the company have gone bust. I do know an honest working fellow that installs units - he suggests that Kelvernator are a no go, Mitsubishi, Panasonic are the ones to look at. Pay the extra cash for a brand name, they're less likely to go bust for a start, and if there is a problem, parts are readily available.

I have a waves airconditioner. Its not cooling well n after some time show e4 error. How to remove the error? Plz help.


http://acerrorcode.com/tcl-air-conditioner-error-codes.html

This was googled: waves error codes
It showed a page in "images". Stated
"System abnormity" I think. Page was blurry.
Call a tech! Mini splits can be a troubleshooting nightmare! I think its a Fujitsu unit. It would help, and may save you some $$, to call around to find a technician who has worked on mini splits. And maybe find them a 1-800 # that is their tech support # before hand, so if the tech needs it, you have it. E4 is a vague description for a fault. Make sure you have cleaned air filters, cleaned o.d.coil (turn off power at breaker 1st). Changed batteries in remote. Work safe!

Code E4


A Canon MP145 E4 Error Code means that your Printer didn't detect the Ink Cartrigde. It sometimes happen when you're using a non-original cartridge or infusing it. When Canon Printer detect this abnormality, the first Canon self defense system is by Stop Printing. And then displaying some messages on your Computer Screen, indicating that your ink cartridge have to be replaced because it's EMPTY.

Below are the manual way to correct this problem :
  1. Turn On Your Printer.
  2. Wait Till The Printer Led Screen Show The Error Code ( E4).
  3. Then Press and Hold Black & Color Button for about 5 - 10 seconds.
Hope that your problem is solved.
