When these parts fail, your unit may not power on, cycle erratically, or stop cooling entirely. We stock genuine OEM LG switches and relays engineered to exact factory specifications.

Replacing a faulty switch or relay restores reliable operation and prevents damage to more expensive parts like the compressor. Our LG air conditioner switch and relay parts come with our repair help ensure and ship fast.

LG Air Conditioner Switches and Relays: Common Questions

Why won't my LG air conditioner start when I turn it on?

A faulty contactor relay or run switch is often the culprit. You'll typically hear the compressor trying to hum but the unit won't actually cool. The relay contacts may be stuck open, preventing power from reaching the compressor. A genuine LG replacement relay will restore proper electrical control and get your cooling back online.

How do I know if my LG air conditioner relay is bad?

Listen for a humming sound without the compressor actually running—that's a classic sign. You may also notice the fan runs but cooling doesn't happen, or the unit cycles on and off randomly. A relay tester can confirm failure, but replacement with a factory OEM part is the fastest, most reliable fix.

Can I use a universal relay in my LG unit?

We don't recommend it. LG relays and switches are calibrated for specific voltage and current specifications. Universal aftermarket relays can overheat, fail prematurely, or damage the compressor. Genuine OEM parts help ensure compatibility and your air conditioner's longevity.

Where do I find my LG air conditioner model number?

Check the metal nameplate on the unit's exterior casing, typically on the back or side. You can also find it inside the user manual or on your warranty card. Once you have the model number, our parts finder makes it easy to locate the exact switch or relay you need.

LG Air Conditioner Model Number: Where to Look

On LG air conditioners, look for the model number on the metal nameplate or label on the back or side of the cabinet. Depending on the unit, you may also find it behind the front grille or inside the access panel. Check the number carefully, including letters, numbers, and any hyphens, then type it into the model number search bar.
