LG Air Conditioner/Heat Unit spits cold air

I have an LG unit that is both our heater and air conditioner. We're currently using it as our heater and it randomly spits freezing cold air out in cycle. The code FP shows up when this happens. I've read the manual cover to cover and can't find any mention of this. How do I shut it off?

    It's both electric heat and cooling

    Is this a heat pump type of unit? Or is it electric heat and cooling?

It's quite simple really.

I live in a dorm which features this very A/C unit, and in the cold winter nights in Santa Fe, it's not the most pleasant feeling in the world, so to solve this problem, we did the most rational thing we could do.

Unplug it

Ahh yes! The kill switch to all modern appliances. If they're doing something you don't like, then just unplug it. When we feel that the room is warm enough and don't want the unit to ruin it with its "Freeze Protection" regiment, we just unplug it until it gets too cold in the room. We haven't had any problems since. :)

I believe the "FP" probably stands for Freeze Protection and it's there to prevent your outside coil from freezing up and causing your head pressure to drop. To do this, it briefly has to reverse the cycle from heating to cooling. This is normal in a heat pump.

LG LWHD1800HR window air conditioner/heater does not heat fully.


It's 115volt and is a heatpump, these units work best above 40 degrees. They only put out between 95 and 105 degree air. The colder it gets outside, the less heat ya'll are gonna get.

Condensation buildup


Make sure the unit tilts towards the outside. If it's installed level or tilted toward front it will not drain properly.

Air conditioner not cooling


Most likely cause is you have lost your coolant/ freon
These low end unit are generally not worth recharging you can buy a new one for less than a tech will charge you to fix it

Carrier spit type air conditioner 5 blinks


Hi, you should have a error chart on one of the panels of the unit that will tell you what the 5 blinks mean. It will be pasted on the unit inside some where. Let me know what you find and we will go from there. Merry Christmas,

how long you last service the unit, when last you cleaned the air filter. Drain pipe might be clogged. If it has been a year it is time to service it

Air not cold


If you are always using it, yes it could be. The heat it produce helps in its normal wear and tear. Corrosion is one and dirt helps. Freon could stay in the system as long as it is not getting any break or hole.

If freon is out of the case. Unit not getting cold, the fault could be dirty air filtter, dirty exchanger, dirt in the system itself, or clog. And also you cannot negate it thermostat, could be its setting or actually faulty. And compressor fault.
