Refrigeration problem. Must be a bad thermostat.

There are two AAA batteries hidden below the keypad under the sliding cover.
Gently prise off cover to real batteries, and replace them.

Thanks for your replies, I had a Sharp authorised tech look at it and im told it's the indoor circuit board. Im told its a $360 repair job all up, that sure beats replacing the entire ac or putting up with the heat...

have you tried pressing the reset button on the plug? (the test button may have been accidentally pressed)

check for input supply voltage

The model number you listed has been discontinued by Sharp. So, getting an accurate retail price is difficult. I did see one online marked Clearance for $269.00. But be careful buying discontinued models, as the warranty may only for a short period of time. Also, customer ratings/opinions on this model, dating back to 2005, were not good.

Hope this helps you and thanks for choosing FixYa.

After you clean the filters as the error message says , you must tell that to the unit (since it can't see or feel what you are doing) by reseting the time counter.
This is the procedure: unplug unit from the mains, HOLD DOWN power button and CONTINUE HOLDING while plugging unit back in (you will most likely need another person for that). Unit will beep. Unplug again, release the button, plug back in and resume normal operation.

Hi, There are no pipes, just passage ways on a window unit. It probably needs cleaned. Window units naturally create water in the evaporator area. The water is suppose to drain to the back of the unit through passage ways to the condensing area where the slinger ring on the condenser fan blade slings it into the condenser coil making it more efficient. There is usually a drain hole to drain excess water from the back of the unit. Any dirt or algae in the pathway of this water or the wrong tilt will cause water to build up and drip or blow out the front. Anything touching the evaporator coil allowing water to run down the obstacle into the wrong area will cause the same thing. reduced air flow will cause the evap to freeze which could also cause a water problem. Since the tilt is right and it doesn't seem to be freezing, Maybe a temporary increase in tilt and a dropper of bleach at the base of the evaporator would do it. This will kill the algae and may unblock the water flow. NOTE: It may also cause stains on a carpet or floor if the bleach water drips onto it. If you want to pull it out and clean it, most units can be pulled out of the housing and sprayed with a water hose but you need to be careful not to get water in the electrical parts of the unit. They can be covered with plastic or foil. Make sure you unplug the unit before trying to remove it. You may have to remove some screws to remove it from the housing. Hope this has helped. kstfas

you may not be giving the a/c enough time to cool down to 72 the reason it goes back to 78 is that is the temp in the room at that moment put on 72 and give it about 20-30 min. to see if this helps

I'm presuming you're not getting any Error Messages on the Remote.

You'll need to try running it in TEST Mode.

Lift the front panel on the indoor unit and press the TEST RUN Button.
The OPERATION Lamp should start flashing and the unit will start in COOL Mode.
Now press the MODE Button on the Remote to change to HEAT Mode.

Let me know what happens.

Window units do produce water in operation but it normally drips to the outside on the ground. If your unit is tilted too much toward the front making it un level the water can drip to the inside. Change the tilt to the outside.

If it's in front of the air ducts at the top of the unit, Yes! Be sure what you're seeing is not the filter. If all else fails, consult your Owners Manual.

E-1 error code means room air sensor defective. Replace it.
