Two things will cause freezeup.

Lack of airflow.
Low refridgerant.

Lack of air flow could be due to :
dirty filter
Dirty coils
closed vents
Evaporator fan not operatriing properly. (also known as blower in HVAC units)

My aw0893l air conditioner does not get cold. do i need freon?


Well first off is the compressor running? When you turn on the unit the fan will start. Turn the unit on to fan only. Then turn it into the cooling mode do you hear something else start? That would be the compressor. Remove the front panel so you can see the cooling coil (evaporator ) if it is freezing and has frost on just part of the coil top or bottom you have lost Freon or a system restriction.. One of the major problems with air cons is a very dirty or plugged condenser coil, which is the outside coil. If you have cotton wood trees in your area this is probably the problem.

Hope this helps Lynn

My air conditioner is freezing up


Hello, the unit will frost from either low airflow ( dirty coil or filter) or a low refrigerant charge due to a leak.

Sounds like the contactor in the condensing unit is stuck. That is why it will not turn off when the thermostat is satisfied. If the inside air handler is not blowing and the outside condensing unit is running, then this will cause the inside coils to freeze up rather quickly.
The contactor is located in the outside condensing uni in the electrical compartment.
If it is sticking it will need to be replaced.

I have an LG Neo Plasma air conditioning unit in the living room and the Inverter in the bedroom. I understand these are set up to work together, however, the bedroom unit starts to freeze up (ice)...


I assume its the outside unit of the bedroom that freezes up ?? If the outdoor temperature is below 5 degrees celcuis, its likely to freeze up on the outdoor coil ( On heating mode), there is a defrost function which defrosts the machine automatically. If the indoor unit starts to freeze up ( on cooling mode), I would suggest that there is a shortage of refrigerant gas. Especially if the indoor unit starts to "spit" water out when it is running. There may be a gas leak due to a pipe failure or loose flared fitting. These must be rectified before recharging with gas.

Mod# PTH093A35AC: Unit has quit running. Blower appears to be frozen up. Prior to non-functioning it was making a loud clicking sound while running in heat mode, almost like coils were freezing up....


yes the blower can be replaced / not all that difficult have a screw gun ready though...several screws to gain access.... the unit normally comes as a sealed system (meaning no actually service ports to add freon but can be ported and a tap added to check and add refrigerant to system... these heat pump systems are great when working correctly ,but when it does drop below 20-25 degrees outside they will start to freeze as the defrost cycles in them are normally not very long and the unit cant keep up so in return they will start to freeze up, however if the blower motor started to go out and unit was running it will freeze up on you.... hope this info helps out feel free to repost with anymore questions you may have.....
