Make sure all the fans are running. Check the air filters and the indoor coil to make sure it is clean. If it is still icing then get the refrigerant charge checked.

Hey mate,
Have you cleaned the filters on the indoor unit. Check the evaporator(in door unit) coils for build up and debris. Check the out door unit coil for leaves and debris. IF they all are clear. Could be low on refrigerant, faulty metering device or a blockage in the refrigeration system.

When the air con is on heating it works fine for about 5-10 minutes and then the compressor stops and then the outdoor fan stops and then the indoor unit stops heating.


This could be any number of problems depending on whether this unit is a heat Pump or not. It sounds like it is a heat pump, if so it should have a defrost board or Control of some type. They also usually have a defrost or ice sensor on the outdoor Refrigerant coil. When ice or heavy frost is detected it puts the unit into defrost. This Could be why your unit is cycling off, the sensor could be bad or the board could be Bad. Also be sure your air filters are clean and the indoor and outdoor refrigerant Coils are clean. This may require you to remove the unit and hose it out.

My outside toshiba split system is leaking a lot of water


If the unit is on heat mode, the outside unit is the "cold" end... Sometimes if the ambient air temperature is very cold ( Under 5 degrees C), the outdoor unit can start to ice up. If it ices up too much, the air con will automatically go on to a defrost cycle where the outdoor unit will heat up and melt the ice. Water is then drained out the bottom.. its the opposite of what happens in the summer when the indoor unit has water running out of the drain hose. Especially on humid days..

My air-con is not as cold as before. I tried to lower the temperature, but when i try setting the temperature to 18 degrees, the remote just shows 18 degrees for like 5 seconds before going back to 31...


These is because you have not service your air-con for a long time. The cooling fins are clotted with dirt & dusts accumulated for a long period of time, and the water vapour caught between the cooling fins turn into ice when you set lower the temperture for the air-con. Moreover cool air from the blower/fan cannot pass thru', the cooling fins to regulate the cool air into your room.

You have to get the professionals to do a service on your air-con.

Hope it clarify your predicaments.

Outside unit iced up how do de-ice


As with the simplest way to thaw ice is with heat.

If you are running this unit in cooling and have ice outside, then you most likely have a freeze up inside as well. If this is a heat pump unit, then frost is normal during operation, however, ice build-up is an indication of a problem.

There are 2 effective ways to remove the ice build-up. The first is the simplest. Get your water hose and hose it down. Be sure to turn off the breakers to the unit and avoid spraying the electrical compartment. If you have the ability to hook the hose into a hot water line, then this process with be extremely fast. Let the unit sit for about 20 minutes to dry out and turn it back on.


The second can be a little more complicated if your not tech savoy. You can turn the system on in the cooling mode. This will make the outdoor coil the condenser section. Then, either block the airflow through the coils with an object, put an object over the fan to increase pressure, or if you can, disconnect the fan so it does not run. This method is essentially the same as a defrost cycle.

As with any failure, you can fix the problem at hand, but it will return. After you get past this, your real challenge will be determining what caused the freeze-up.


If you were running your system in cooling already, then you will need to ensure the system has de-iced on the inside as well.
