LG LW1217ERSM1 Wi-Fi Window Unit for 550 Sq Ft Repair

LG air conditioner

Most common issues on this model

  1. Wi-Fi pairing with the ThinQ app
  2. Panel and remote temperature changes
  3. Cooling output in a 550 sq ft space
  4. Fan mode selection
  5. Coil and drain condition

Wi-Fi is built into the LW1217ERSM1, a 12,000 BTU LG window air conditioner listed for spaces up to 550 square feet. You can control key features with the ThinQ app, pick high, mid or low modes for cooling and fan speed, and make changes at the panel or with the remote.

With three ways to control one unit, we first find out which one is failing. If the panel works and the app does not, we look at the Wi-Fi link. If none respond, we test power to the board. On the cooling side we inspect the filter and coil, listen to the fan, and measure the compressor start. We take the model and serial from the label before we order anything, and the price is given in writing before we begin.

LW1217ERSM1LW1217ERSM1 questions
The app and remote both fail. Is the board bad?

Not necessarily. We check power, the panel and the receiver first. If the unit runs from the panel, the board is working and the connection or remote is the issue.

What do high, mid and low modes change?

They set the cooling and fan strength. If one mode behaves differently than it should, we measure the fan motor and check the board's output for that setting.

Can you reset the Wi-Fi link?

We can walk through the reset and pairing steps. If the unit still will not connect, we test the unit's Wi-Fi hardware and tell you what we find.
