Question about Sharp CV-P09FX Air Conditioner

1 Answer


The unit is completely drained but the lights (RED YELLOW GREEN) are blinking and the unit won't work.  These lights according to the manual mean that the water tank is full it and needs to be drained.  The tank was never full and I went through the draining procedure to be safe but the lights still blink. Anyone got any tricks?

    I'm experiencing the same problem. We drain both the top and bottom ports but that only works for a few minutes before the lights start blinking.

Hi all,

I think the problem is that the A/C has tripped the electrical switch located in the plug. To correct press the black button followed by the clear button. Then try turning the unit on -it has worked for me so no reason it should not work for you.

    Hi everyone,

    Here is an important follow-up. The reason most of the folks are having this problem is that we were proactive and emptied the water tank. The electrical switch is tripping as I mentioned above which is why the green, yellow and red lights are blinking.

    The A/C cabling is tripping because you most likely have left the top switch which is a turnable knob in the wrong position (where the straight edges are vertical instead of horizontal). Turn this to the horizontal position to have your A/C operation return to normal.

    This didn't work for me. Each time i reset it, it will run for about a minute, then the pump will kick on for a minute or two, even while empty, and then it shuts off with the "three lights of doom". I've double and triple checked the horizontal/vertical drain tube plug, and have even sat the unit on it's back to make sure all residual water is out. What do i do, now?

This type of unit does not drain into the outside unit. It drains into a nearby interior drain, or just to the outside near Inside unit. If the unit is cooling properly, you're ok.

Water light is blinking

The "water light blink" is an indication the water collection tank needs to be drained. Depending on the unit you have, most drain plugs are on the rear of the unit, just above the floor. You can drain it into a low sided pan or bowl capable of holding up to 1 quart of water or roll it to a floor drain or outside and drain it there.

I hope I was able to help you and thanks for choosing FixYa.

Orange and red light blinking after one minite

I fixed this problem by disassembling the panels. On the front then sides then back of the unit. The first thing I noticed was some debris in the exhaust fan wheel on the back side. I used some long wood skewer to fish out the debris and even shook the unit upside down. (It's very heavy and would recommend help with shaking the unit.) Also, I think i found a little sensor that is about the size of a thumb drive and incased in a transparent plastic box. I tapped it with my finger and noticed this little black thing bounce up and down inside under the green circuit board. its located right above the drain connection. I didn't do anything else with this. I assumed its the sensor to measure the water buildup. I also found a small toy in the front fan wheel that blows the cool air through the top of the unit. fell out during the shake down. The final thing I noticed was when re-assembling the unit. On the front side you will see the two metal radiator looking panels. Between the two panels is a wire sensor that looks like a temperature measuring device. I had noticed it was touching the metal part of the radiator panel so I gently streightened it out so that it was parallel with the panels and not touching. I pressed the power button and it hasn't shut of yet. I snapped the front panel back on and all is good.
I have the white upright sharp AC unit with the three lights in the front and a power button next to the IR sensor. I lost the remote control and couldn't figured out why the unit would start up then shut down after a minute of use. The operation light would blink red then the orange timer light would blink next. Then both lights would blink simultaneously, then repeat. I thought this was a timer setting. but the unit is supposed to reset after disconnected from the power.
