just guessing, seems like the compressor is siezing up and blowing the fuses

Either compressor is going bad or the fan is rubbing. There is a condensor fan that comes on only when the compressor starts. So check the fan out first to make sure that it is not rubbing or moving around. If that is not then check the compressor by letting it run for about 5 minutes then touch the top of the compressor. BE careful as it can be extremly hot that will show you one of two things either bad compressor or condensor is dirty and a garden hose with a jet blast of water will solve the problem. If that doesnt work either compressor is bad and will either need to be replaced for about 250 dollars or unit will need to be replaced

It should remain there it is the insulation seperating the condensing side from the evaporating side you may nve to reach in and move it around to prevent the destruction of the foam.

Is it installed in a window? Check to make sure it is installed correctly. usually there is a felt or foam strip that is used to dampen vibration when you place it in the window. It also acts as seal to keep outside air and bugs out. If you place your hand at various locations on the unit does the sound go away? If it does then you know it is a vibration problem. Just add new foam or re-adjust the foam or gasketing it already has. If that doesn't work then try to locate the source of the noise. Use a mechanics stethoscope or even a cardboard tube from paper towels will work. Once you have located the source then you can tell the store what the problem is when you take it back and get a new one. Cheap air conditioners are noisy. Some more than others, it's why they are cheap. But your problem does sound like it could be a product issue.

It needs to be installed sloping slightly outside. It is not meant to be level. Use boards or whatever to do this. If this doesn't solve the problem the drain channel is plugged. Take off the outer case and look at the bottom there should be some kind of channel from in front to the back. Use a turkey baster or something to flush it. The back may be fairly deep to hold some water. Don't drill a hole. Some units keep some water in the back so the outside fan can throw it through the condensor to help cool it.

No, you can not turn it on its side. That is a no no. You are between a rock and a hard place in this case. No to your second question also. If you are really desperate you can put it part way through a door frame and block off the rest of the door as a temporary measure.

check the breakers that feed it first.

there should be a rubber plug on the right hand side from the outside 2 black round " corks" if you see them remove them and your problem should be solved

Unit is low on Freon. Take it to a repair shop to find the leak & recharge the unit.

I would start by checking or having the motor run capacitor read for it's value in microfarads.

Question edited for clarity and add maker. Try a reset. Disconnect mains power for at least 2 hours. Reconnect and wait 5 minutes before turning on. This resets the mainboard and initiates a self test procedure. https://www.google.com/search?q=+Haier+CWH24A+not+heating+up ..

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 ac

Haier ac remote

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.
