Hello, I have a Fujitsu ASU12CQ wall mounted air

SOURCE: Fujitsu wall mounted air conditioner leaks into the room

Make sure the unit is level, this is very important. Check for blocked drain tube, which runs from the bottom of the drain pan under the cold coil to the outside. Clear tube with a piece of coathanger wire, be gentle.

Is it a split system? I had the same problem with my split system and and it was because the condenser line was mounted wrong. The line was mounted so the water had to go uphill and it was causing the condensation to leak through the front of the unit.

I bought window AC (5000 btu) that fit 17 in. at home depot. made by Zenith. Keep in mind of your room size.
Good luck.

I had a similar problem with only fan air then the blinking lights, found out that mice had got into the circuit board and corroded some connections with their urine. I would try the above solution by turning the power off for ten sec first but remember that you have to leave it for a few minutes before you operate remote.

hi! there,
if no cold blowing,evaporator is not working,have you ever heard compressor is running,check this out,no compression of course you dont have cool on evaporator.if the compressor is running check the oprating current,if still have enough freon charge,if not running check thermostat reset setting on the coldest,ifn still not run check overload relay on panel control reset lever to put back compressor to run,check condensing fan if working,if not check also over load protection,this should be done by ac tech nician.have a nice day,dont gorget to rate me, thank's
