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.
