The icing problem is caused from either low airflow across the evaporator coil (inside coil) or a low charge of refrigerant. Make sure your inside coil and air filter are clean and the fan is running at normal speed, if those are OK then call a service tech to check the refrigerant charge and adjust as needed.

Hi!!

It is the drain tube clogged or the unit is not leveled.

The drain tube is on the right side of the air handler, if the unit is leveled, lift front grill and remove the screw fastening the small cover on the bottom right corner, remove cover, you should be able to see the drain hole, use a piece of wire to unplugged, if that does not work, go outside and blow on the drain hose to clear the obstruccion.

Good Luck!! Don't forget to rate this post!!

You will be able to get the answers from Haier support in your country. We are Fixya, not them. It sounds like a control board fault. You can try a reset. Turn it off at the breaker for 2 hours. Switch it back on and wait 5 minutes before turning the unit back on with the remote. https://www.google.com/search?q=Haier+Thermocool+AC ..

On a Haier Split system a E7 error is a failure of the outdoor inverter PCB and the outdoor power supply PCB. Both will need replacing. Looking around $600 for those parts. Plus fitting. The indoor PCB is very unlikely to be needed.

Window units do not come with service ports. You can buy them at local parts houses, but unless you have the freon, not gonna do you any good. Window ac use either r22 our 410a, and that cannot be bout without being certified.

switch fro auto to cool function.

Having the same issue, it's a shame the only answer is telling you to do what you clearly said you had already tried.

Take it back and get another one. Once you try to work on it, void the warranty.

This is a communication error between the indoor and out door units.

Have you tried UTUBE?

Hello, some window units do not have a drain hole for the condensate, instead the use the fan blade to sling the water on the condenser, since the condenser is warm/hot it will evaporate the condensate.

The screws are hidden behind plastic plugs. Remove them and undo the side panels. Once they are off you can get to everything else. https://www.google.com/search?q=disassemble+a+Haier+portable+air+conditioner ..

It is likely a Haier, not a 'Haiser'.. It is a AC Unit, so shouldn't be in the Category Cars and Trucks. I can change those. Your answer is twofold; You need a remote, Google make model replacement remote You pressed a button combination set, Google make model manual
