Listed for rooms up to 1,000 square feet, the LW1816ER is an LG window air conditioner with 18,000 BTU of cooling, a remote for temperature, fan speed and mode, Energy Saver mode, 4-way air direction and Auto Restart. The LW1816HR version is grouped with it.
A big unit like this is often asked to cool an open floor plan, so we start with how much cold air it really delivers. We check the receptacle and cord, the filter and coil, the blower and the compressor start. If the unit trips a breaker or hums, the capacitor and compressor current tell us the most. We read the label for the full model and serial, order matched parts, and give you a written price before we begin.

Error codes this model can show
Why does the unit hum without cooling?
A weak start capacitor or a hard-starting compressor is the usual reason. We measure both and explain the options and price before any part is ordered.
Does the HR version heat?
The listing includes LW1816HR, but we do not assume its features. We test what your unit does and match parts by the label. Parts for suffix versions can differ, so the label settles it.
What area is the unit made for?
It is listed for up to 1,000 square feet. We measure the real cooling output, since sun and open doorways also affect how the room feels.
