Note:wiring connection is wrong or proper volt is not being supplied.

Hello sir please don't swirtch on your Air Conditioner.There is some short circuit happening in your system.Check weather proper volts is flowing into the A.C.Some sort of wrong connection is being done which will cause the system warranty to be void.So please call the service engineer to work on it.I can help you out in this but you need proper hands on in it.

HL-High Limit (Float Switch) means Float switch Open circuit Off.Drain pump / Float switch-Float switch Open circuit (High level water alarm).

HS means -Heat Sink Sensor Temp. High-Heat Sink Temp. High-Open / Short circuit.

post a comment for further assistance.
Thank you for using fixya have a nice day:-)

    Have you checked -Heat Sink sensor and drain pump then that could be the problem
    Is this a new Air Conditioner or Old one.Officially HS refers to this sensor issue.Open the A.C check the board are ok.DO continuity testing.So you can find out the cause if its the board problem.

Model WS9611UN-IT - I am unable to receive the outdoor temperature. I have changed the batteries on the outside remote but I still do not receive the outdoor temperature. How can this be corrected

Remove all batteries, both outdoor and indoor. Install batteries in outdoor unit and wait for it to begin sending a temperature signal. Install batteries in indoor unit. You should see outdoor temperature displayed. If not, batteries, transmitter, or indoor unit may be defective.

You have to remove all batteries, both outdoor and indoor. Install replacement batteries in the outdoor unit. Back indoors, install replacement batteries in the indoor unit and wait for temperature to be displayed. If nothing happens, the outdoor unit may have failed.

I have a contractor that wants to install a 36000btu outdoor unit(model # mh080fxca4a) and two indoor 18000btu indoor units(model #mh052fnca). What would be the output of the outdoor unit? The contractor...

Yes it rated for a maximum out put of 36,000 btu (3 ton) with the right indoor fan coil units which based on the model numbers should give the 36,000 btu's combined when both fan coil units are on, otherwise 18,000 btu's (1.5 ton)per fan coil.

Steamed up windows carrier humccsbp2412-a

it should not run while the fan on the furnace isnt running and if the humidity in the house is higher then the setting on the humidistat(HS). If he mounted the humidistat on the duct you need to make sure he cut a hole to allow the HS to sense whole house humidity thru the return air duct. if you turn the knob on the HS if you listen closly you should hear it click indictacting the humidity level as you raise the dail when you go above the indoor hum it will click and the humidifier should turn on and vise-versa. if it doesnt turn off /on when you hear the click then its wired wrong.
