Hose seal at the window
Drain path and filter airflow

The LG LP1311BXR is an older portable air conditioner rated at 13,000 BTU and supplied with a remote. It has a programmable on/off timer and an electronic thermostat with a digital display, and it exhausts heat through a hose.

At this capacity the unit moves a lot of air and makes a lot of condensate, so the drain and the hose get attention early. We look for water at the base, check that the hose is tight at both ends, and then test the timer by setting a short run. A thermostat that cycles the unit off too soon is compared against the room temperature.

The remote is tested next, because owners of this older model often rely on it. If a control part is needed, we find it from the model and serial on the label and tell you whether it makes sense for a legacy unit. A written price comes before work, with a 30-day warranty on our repair.

LP1311BXRLP1311BXR questions

Why does my portable unit leak water?

A blocked drain, a tilted base or heavy dehumidifying can all do it. We trace the drain path and level before replacing anything. With a 13,000 BTU unit, a large amount of moisture passes through, so a partly clogged drain shows up fast.

Is the LP1311BXR still serviceable?

It is an older model, but many still run well. We check the airflow and controls, then give you a written price to weigh against replacing it.

The timer is ignored. Is that the board?

If manual operation works but the timer does not, the controls are the likely area. We test the timer first so we do not replace parts needlessly.
