LT103CER
LG LT103CER Through-the-Wall Cooler Service
Most common issues on this model
- Which of the three builds you own
- Auto Cool and fan speed
- Louvers
- Coil, filter and rear drain
LT103CER is an LG through-the-wall air conditioner with a universal sleeve fit, Gold Fin anti-corrosion, three cooling and fan speeds with Auto Cool and 4-way air direction. The LT103CNR and LT103HNR share the design. It is a legacy model.
With three numbers on one design, the label settles which build we are working on, and we read model and serial before any part is ordered. After that we pull the chassis and work through speeds, louvers, coil and drain.
If your build has heat, we test that mode too. The price is written first and a 30-day workmanship warranty follows the work.

Error codes this model can show
Which numbers belong to this design?
LT103CNR and LT103HNR are listed as variants. We read your label to see which build you have.
Why is my wall unit noisy?
Noise on units of this type often comes from a loose fan blade, a dry motor or a rattling panel. We locate it before replacing parts.
Can the louvers be repaired?
Often the movement can be restored by clearing the louver or replacing the drive. We test before quoting.
