Air condition want cut off automatic

You may have an air lock try using machine on and off 5seconds each time sow that you give the pump time to regain the water.
If not try and inject water your self from the rare instead of water tank some time when you get air lock it is removed alone by just simply leave it over night after you had tryed the water pump because the air lock is removed alone slowly.

Try changing fuel filter and air filter may even need good tune up always add injection cleaner hope this helps been a mechanic 40 years

Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run. The compressor is locked and will not start. What is happening is the compressor is trying to start, but because the compressor motor is locked it tries to start for a few seconds and then because of the high amperage being drawn goes off on internal overload. The internal overload protects the compressor windings from overheating and burning up. I see this many times during the start of the air conditioning season.

Check the fan relay. These relays are used to cut the fan on and off when the thermostat is set in the air conditioning or heating mode or when you move the thermostat to the "Fan On" position. The low voltage usually the green thermostat wire is wired to terminal #1. The low voltage common wire to terminal #3. One line voltage wire is attached to terminal #4. The high speed blower wire usually black is attached to terminal #2. When the thermostat calls for air conditioning or "Fan On" the 24 volt coil is energized, the terminals 4 and 2 close. This causes the fan to come on in high speed. When your home cools down and the thermostat cuts the air conditioner off, the low voltage coil terminals 1 & 3 are denergized, and the fan goes off. Sometimes these little relays stick which causes the fan to run all the time or will not make good contact, which causes the fan to not run in the "Fan On" or air conditioning mode.

Sounds like you're trying to re-start the AC too quick.

Since the compressor has to 'equalize it's pressures' before it will start (after being cut off) - you will always need to give it plenty of time (after cutting it off) before turning it back on.

If you are referring to 'automatic' operation - it is the thermostat that 'cycles' the unit and this is determined by the 'rise and fall' of temperature.

Thermostats are notorious for being a little out of adjustment and as long as the AC is cooling the space I would not worry too much about it.

If it gets to be a big problem - you will probably need to change out the thermostat, but I would have a Service Tech check out the complete operation of the air conditioner.

good luck!

you might need a new thermostat

I have a 2008.5 Mazda 3 GS Sport and when you turn the air flow selector to windows or windows/floor, the air condition will turn on automatically. (Can't turn it off.)

My guess would be from what you have described is that the refrigerant pressure might be low and is tripping the low pressure cut off that protects the compressor.
