If its older than a fee years you may need to clean the outdoor coil. It may be shutting down due to high pressure. I couldn't locate a Google hit so I'm assuming its a window a/c? If so the "air entering" side of the outdoor coil can get dirty and you normally can't see this side until the unit is removed. But you can try to UNPLUG IT FROM THE WALL!!! And the take a water hose and spray from the outside of the outdoor coil. This will try and remove debris. Its always best to remove from window to clean if possible. If the outdoor coil gets dirty it will retain its heat instead of rejecting it to the atmosphere, and heat retension will increase freon pressure causing a high pressure/temperature sensor/switch to open.

You may have changed the setup to display in metric (degrees Celsius).

The red light on this model indicates, like a dehumidifier, that the internal condensation "tank" is full. This unit normally discharges excess humidity through the exhaust vent. When humidity is excessive the unit cannot evapoate all the moisture out the vent pipe. There is a black rubber plug in the back bottom of the unit. Get a very shallow pan that will fit under the unit and pull the plug. After it has drained completely, run the unit on fan only to continue to dry out the internals. After 30 minutes or so, switch to cool and it should run. If the unit shuts off again after about 10 to 15 minutes, you have some sort of blockage that is causing the moisture to backup and trip the sensor. You will have to take the back off the unit and remove the blockage.

Take out the filter and pour water on the oposite side that is the dirt,if the water is not enough use degreaser and also clean thefront cover where the filter goes.

It sounds like the compressor is not running. This could be due to a faulty thermostat, a bad start capacitor for the compressor, a bad compressor overload or simply a bad compressor. You would need a voltage meter to check all of these components.

A capacitor stores energy for starting or running electric motors in most cases, however, they have many many many other uses, but storing energy or raising voltage for use at a latter time is there primary use.

Hi,

Yes probable you may need a new fan motor but check the capacitor first.

There is a low freon pressure switch in the system. A small amount of freon will show enough pressure to start the unit. As soon as the compressor starts the low side pressure (where the switch is) drops and shuts the unit off.

This usually indicates low freon or an open window drawing humid air into the unit.

The thermostat sounds like it's bad. If it was good, you could change the temperature settings. The thermostat has to send a signal to the control board, and if it's bad, that just won't happen, and no cooling can occur.
If this unit is a room air conditioner, here is how to check the thermostate on it:

Good luck, and hope this helps.

I have the M6P09S2A Portable unit that is leaking water everywhere. I have to place it in a large bin to keep it from draining on the floor. Any solutions?
