LW1823HR
LG LW1823HR 18,000 BTU Heat and Cool Window Unit Repair
Most common issues on this model
- Heating output at the vents
- Cooling output in a large room
- Mode and speed selection
- Compressor start and receptacle load
- Auto Restart after an outage
The LW1823HR is an LG window air conditioner with 18,000 BTU of cooling and 12,000 BTU of heating, listed for rooms up to 1,000 square feet. It has two cooling and heating speeds plus two fan speeds, an Energy Saver mode and Auto Restart. The HRSM version of the same number is grouped under it.
Because it covers both seasons, we test cooling and heating separately and confirm that the unit changes modes cleanly. We look at the filter, coil, fan and compressor start, then at how each speed performs. A large unit also warrants a look at the outlet, cord and window support. Parts are ordered from the model and serial on the label, and you see a written price before any repair.

Error codes this model can show
Why does my unit cool well but heat poorly?
Heating uses a different circuit and a sensor input. We test the mode, the heating output and the fan, and report what we find before any part is ordered.
How much heat can it provide?
The listing gives 12,000 BTU of heating. Cooling is higher at 18,000 BTU, so heat is milder, and we check that the unit meets its listed output.
What happens after a power cut?
Auto Restart restores your last settings. If it does not, we look at the control board and its power supply. That tells us whether the problem is in the settings, the board or its supply.
