LW1213HR
LG LW1213HR Heating and Cooling Window AC Repair
Most common issues on this model
- Heating mode that does not warm the room
- Switching between cooling and heating
- Fan speed and air direction vanes
- Coil frost and drain path
- Remote and panel input
The LW1213HR is a legacy LG window air conditioner that handles both seasons, listing seasonal heating and cooling with multiple speeds for each, 4-way air direction and a remote. It is an older model, still in many homes.
A two-season window unit adds a mode to verify. We test cooling as usual, then switch to heating and confirm the room air actually warms, the fan follows, and the unit changes modes smoothly. If heat is weak, we check airflow and the heating side before looking at the board. As always, we read model and serial from the label before ordering a part, and you approve a written price first.
Key features
- Window unit for heating and cooling through the seasons

Error codes this model can show
My unit cools fine but will not heat. What is checked?
We confirm the mode selection and sensor, then test the heating side and fan. Whether the repair is simple depends on what we find, and you hear the price before we go ahead.
Can I run it for heat in winter?
The listing describes seasonal heating and cooling, so yes, for the rooms it is sized for. Weather and insulation affect results, and we check that the unit itself is producing heat.
Why does it switch modes slowly?
A delay can be normal protection, but a long wait or no change points to the control board or selector. We test the mode switching and tell you the result.
