LG LSU/N 242 HE install

Installed the units, fans work, but no heat or cooling.  When heat is turned on the de-ice indicator on the inside unit lights up.  Any ideas?
Thanks, Dan

    Had the unit checked out today.  Short of it was that the return/suction valve was not all the way open, restricting the flow of refrigerant.  So was it my interpretation of the instructions or ?  The pressure was good. Thanks for your efforts.  I need to re-check the instruction pages.

It is possible that some of the refrigerant has been lost from the system during installation. These are normally pre-charged systems and the amount of charge is critical.

No heat but fan keeps running


If the air conditioner compressor runs all the time the main control board might be defective. The main control board provides the voltage to the fan motor and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem.

Installed 18000 btu split system heat pump and condensing unit is freezing up in cold weather 15 degrees out side air.


Actuall, out door fan sucks fresh air to cool the condensor when it's on "Cool" mode. If it is in " Heat mode' if the fan should run only on pressure build up. May be pressure switch is faulty.
Melt the ice with Torch gun, and check again.

We gave a Goodmn Hertz 60 Phase I heat pump - installed this summer....worked great for cooling..now that temps are dropping we are needing heat. When we turn it on it comes on but never heats. Think it...


If you changed the unit but didn't change the thermostat it is possible that the thermostat that you have will not work with that unit. I see that the unit you installed is a heat pump, you may have a straight cool T-Stat. If you put the T-Stat in the "Auto" "Heat" mode the outdoor fan and the compressor should be workng as well as the blower fan. If it turns out that the outdoor fan and compressor are not running you will want to buy a Thernostat that is compatable with heatpumps should be 2 heat/ 1 cool

I have a Panasonic CS/CU-W18DKR - on cooling it works fine, auto aswell as fan, but on heating when it is on manual fan control it used to blow all the time, but not for some reason it only blows...


When the unit heats inside, the outdoor unit cools, and if the outdoor cooling coil gets too cold the system turns off indoor fan, and changes gas flow direction to de-ice the outdoor coil. Ensure both coils, and the filters are clean and if there is still a problem check system gas pressure for leaks.

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.

Should the LG LS-K-1830CL outdoor unit ice over on the coils when operating in the heat pump mode? Would this cause the unit to not properly heat the room?


Running the heat pump in low outside ambient temps. will definitely cause the coil to ice up. An ouside temperature senor or a wind baffle should be installed in climates that get below freezing. This would definitely cause the heat pump to operate at lowered efficency and maybe not at all. It should go into defrost mode if the sensor is working correctly when the coil ices up.

LG PTAC acting strange in heat mode


I believe the problem in lies in the dual stage heat mode setup on the thermostat, but the unit going into defrost does make the unit act kinda strange. Even more so than other types of equipment. I would suggest hiring a licensed HVAC service technician if the problem cannot be resolved by yourself.
