I had the same problem. I found the micro-switch for the water level was faulty. This switch had a high fluctuating resistance. I was able to correct the problem by spraying some contact cleaner ( or use TV tuner cleaner, alcohol might even work) into the switch. The resistance then dropped to 0.6 ohms. The only place I saw to get the cleaner inside, was around the depress-pin itself. It obviously got inside. If facing the unit, this micro-switch is located on the left lower inside, you can't miss it. You can see where the water float level lever mechanism depresses this switch. Getting the cover off was aggravating, but wasn't too bad. Remove the front cover's 2 bottom screws and lift up and off the front. Remove the left side 3 screws and the rear panel 4 screws and this gave me enough play to prop up the left side panel to get to the switch. The switch removes super easy. For troubleshooting purposes, you could jumper the 2 wires together, that are connected to the switch, as the switch is used in a 'normally closed' application. Essentially bypassing the switch. The unit should then power up and function correctly ( Temporarily ) Hope this helps.

Possible that the vent or the vane is blocked which can also be due to a jammed motor in the auto oscillation vent. Remove the panle and check the free movement which will confirm this case. Sometimes it could be dirt that is logged in that prevents free movement.

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 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.

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?
