Hi
Frosting will sometimes happen if the outside temperature is to low. The outside ambient temperature is directly related to the pressures inside the refrigerating system. The lower the outside temperature is the lower the pressures will be in the cooling end of the air conditioner. In mechanical refrigeration pressures and temperatures are directly related.

    Frosting of the cooling coil can be caused by ether of two conditions. With a normal operating ambient temperature such as with you location there is a possibility you unit is a little low on refrigerant charge in the system or there is possibly a restriction in the refrigerant line feeding the cooling end of the system. However it would still come down to product value and cost of repairs.

You may need to have the fluid checked, these tend to frost up when the coolant starts to run low so once it expands it expands faster due to less pressure and therefore ices up the radiator.

Check that the evaporator fan is working, usually there is a thermic system that starts the defrost system, give me model number so that I can try finding the schemattics.

    If the evaporator system is working fine, follow the steps below:

    Ensure that there is air circulating at the back of the AC where coil is freezing up. If thee is no enough air circulation, the evaporator system won't work properly, and the condenser wont be able to do its job.

    Clean the air intake filter. Accumulation of dirt and dust residual in the filter can slow down the air flow and cause the unit freezing up.
    Blow the filter with compressor , if you do not have a compressor clean the filter with water, and dry it carefully before installing it back.when running in the AC Cool mode. This will move air through the evaporator unit faster and will keep it from freezing up.

    Turn the fan to high when running in AC mode, this will allow more air circulation and can help preventing the AC from freezing up.

    Set the thermostat to a lower temperature closer to the current temp inside your place. This allows the compressor to cycle, so that the AC can shed the frost before cycling again.
    If you set the thermostat 40 to 50 degrees lower than the ambient temperetaure, freezing up will be normal.

    If there is excessive moisture in the ambient(like when having a shower, or a pot boiling for a long time), open a window or a roof vent. The moisture gets drawn into
    the AC, where it condensates and freeze.

    Damage to the condenser fins, can reduce the cooling capability of the AC. And also cause freezing.

    More reasons
    why an air conditioner may be freezing up can be a split plenum, bad
    fan/run capacitor, a grounded or shorted motor, and low freon levels
    but, try first chcking the simple things in the list above, if the AC is really defective you may need to call a technician.

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 LG mini split want cut off. I can cut it off on the unit but it still runs wide open it will not cut off by the remote either. any help appreciated.


This sounds like a faulty thermostat (indoor unit), or a welded (shut) set of contacts in the condensing unit (outdoor unit)

[frozen heat pump coil], freon checked,contactor replaced,outdoor defrost thermstat repaced..worked all of a very cold december,temp rose to 50 degrees for 2 days,7 once temp dropped again,coil froze up...


THE ONLY THING THAT CONTROLS THE DEFROST CYCLE is the defrost thermostat and the actually defrost control board. along with making sure there is enough freon in the system to switch the unit over and move the reversing valve when it is time... if they have changed the defrost thermostat and you are positive the freon level is good the it appears you may have a bad board on the unit.... be advised the unit should frost up in cold temps and is normally to have frost built up on it then will go into defrost mode. if the unit is freezing over then yes you have a issue.
good luck to you

The heat keeps going in defrost


Please check your thermostat setting not more than 28 or 29. And also check for your heating sensor that regularly cut off or not.

Fan freezes up with ice in winter


They need air, do not cover it when in use.

If ti cools fine in summer then you just have a defrost problem.

Make sure the outdoor coil is clean.
If the coils are clean, then you have a bad defrost control.

In heat mode the unit should go into a timed or temp controlled defrost. If it is frosting up to the point of stopping the fan, in heat mode only, and otherwise operates properly, then its a bad defrost control.

It is reccomended that the defrost temp sensor be replaced at the same time the defrost control board is replaced. Some temp sensors are part of the board and not a seperate component, but not most.

LG LS-K2430HL still not defrosting


Low refrigerant charge is possible. Unit will sometimes freeze up. This is normal. Is the unit satisfying?
