LT1234CNR
LG LT1234CNR Wall AC with 8.8 EER Repair
Most common issues on this model
- Cooling output that drops with a dirty coil or filter
- Compressor and start capacitor operation
- Fan motor speed and blower wheel balance
- Drain pan and sleeve seal for leaks
- Controls and sensor reading against the room
Here is an older LG wall unit rated 11,500/11,200 BTU with a cooling EER of 8.8. The LT1234CNR is a legacy model, listed together with the LT1234HNR number, and it is made to fit a universal wall sleeve with a Gold Fin coated coil.
A unit this size is normally in a bedroom, den or small apartment wall. When the room warms up, we compare the air coming out against the room temperature, then inspect the coil, filter and blower wheel. We test the compressor and its start capacitor, and we look at the drain pan for buildup. The label tells us the exact model and serial, so we match the part to your unit before ordering, and you see the price in writing first.

What do the two BTU numbers mean?
The listing shows 11,500/11,200 BTU, which are two ratings for the same model line, usually tied to voltage. Your label shows which one applies to your unit, and we read it before sizing any part.
Is the unit worth repairing?
If the coil, sleeve and chassis are sound, a repair like a capacitor, fan motor or sensor is often reasonable. If the sealed system is leaking, we say so honestly and explain your options.
Why does the room feel humid but not cold?
That points to low airflow or a coil that is frosting over. We check the filter, coil and fan speed, then the compressor, since short cycling or a weak start also leaves air damp.
