LW1814HR
LG LW1814HR Seasonal Window Unit with 18,000 BTU Repair
Most common issues on this model
- Heating output that is weak or missing
- Cooling output on an 18,000 BTU class unit
- Compressor start under a large load
- Receptacle and cord condition
- Mode switching and fan speeds
The LW1814HR is a legacy LG window air conditioner rated 17,500/18,000 BTU for cooling and 9,800/12,000 BTU for heating, with a cooling EER of 9.7 and multiple speeds for both seasons. It is an older, large-capacity unit still found in many homes.
A unit of this size draws a lot of power, so we begin with the outlet, cord and breaker for signs of heat. Then we measure the compressor start, check the fan on each speed, and clean-check the filter and coil. Heating gets its own test, so we confirm warm air and the mode change. The label tells us which of the paired ratings applies to your unit, we order parts by the model and serial there, and you approve a written price first.

Error codes this model can show
Why does the listing show two sets of BTU numbers?
The two figures are ratings for the same model family, so your label shows which applies to your unit. We read it before we judge cooling or heating output.
Is heating on this unit the same as a furnace?
No. It adds warmth to one room and its output is listed lower than the cooling figure. We check that it produces the heat it should.
Why does it trip the breaker when the compressor starts?
A weak capacitor, a hard-starting compressor or a worn outlet can do that. We test current and the outlet, then explain our findings before any repair.
