Yes, the ac will run in the defrost position to dry the windshield.
If the ice formed while the unit was operating it is a heat pump. The defrost board or whatever other control you may have to initiate the defrost cycle is probably bad. Switch the unit over and run the air conditioning, that wil defrost the ice until you can have it repaired.
If the defrost is on, the ac will be on, and the condsensor fan will be on.
does fan door motorized or on a vaccuum line when you switch from AC to defrost?
The systems AC system will run when the defrost is turn on.The manufactor does this to remove humity from the air making it easier to defrost the windsheild.The AC system should only run when the defrost is on though.If you are experiecing a high pressure promblem when the AC is running it is pronbly due to a overcharge of refrigerant.
i want to run a two ton ac with solar power
do you have a heat pump? are you running unit in heat? if so and the steam is comming from outside unit, this is normal in the units defrost cycle
Yes, it will run when in defrost or mix.
The defrost timer, thermostat or logic board, whichever you have is probably bad. To quickly remove the ice build up on the outdoor unit switch it to run the ac for a few minutes or until the ice clears.
no the dc unit will be damaged . but , if you have no other options left then you have to use a rectifier to convert the ac into dc .
Imagine a window AC unit installed backwards, rejecting heat indoors while air conditioning the world, this is a heat pumps heat mode. As the unit is air conditioning in the cool outdoors eventually the outdoor coil will ice up requiring a defrost cycle, defrost is the AC mode except the outdoor fans off to assist with the defrosting. A defrost cycle is time and temperature initiated, time or temperature terminated.
If you have the selector knob on defrost it will also run the air conditioner compressor.
