LG LW7012HR Window AC Repair

Most common issues on this model

Remote response compared with the panel
Timer operation
Thermostat and display readings
Cabinet seal and drain
Filter and coil airflow

The LG LW7012HR is an older 7,000 BTU window air conditioner that comes with a remote. It has a programmable on/off timer, an electronic thermostat and a digital display.

With a remote in play, the first test is simple: does the unit respond from the panel and from the remote? A unit that obeys the panel but not the remote usually has a remote or receiver problem, while one that ignores both points to the controls or power. We then test the timer and compare the display with the room.

We also inspect the filter, coils, window seal and rear drain, which decide cooling on any window unit. For a legacy model we say plainly whether a repair is worthwhile. The label gives the model and serial, which we confirm before ordering a part, and the price is in writing before we begin.

LW7012HRLW7012HR questions

The remote no longer works. Do I need a new unit?

Not likely. We test the remote and the receiver on the unit, and replace only the part that has failed. This 7,000 BTU unit comes with its remote, so we also check that the batteries and sensor window are clear.

Is the LW7012HR an older design?

Yes, it is a legacy model. We give you a written price so you can compare repair and replacement. Some owners keep this older unit because it still cools, and we help you decide if a repair is worth it.

What do you check if the timer does not run?

We test the setting and the controls, since the unit may run fine manually while the timer fails. The unit also has a thermostat and digital display, so we confirm they work normally before replacing a part.
