Is CH on a LG refrigerator an emergency?

Treat it as urgent — deal with it today. If water is reaching outlets, cords or the floor near anything electrical, switch off the breaker before you touch anything, and shut off the water to the appliance.

Take the photo. We’ll tell you what it is.

What CH means

“refrigerant leak on the high pressure side”

— LG USA, [LG Refrigerator] Digital and Analog Error Codes. Codes vary by model: check your refrigerator’s own manual.

Where CH fits

In plain words, CH is about water where it should not be — the machine has sensed a leak or an overfill and stopped.

Next to CH in LG’s table: gF (malfunction in the appliance's water flow sensor) and Lo (ambient temperature has dropped below -10 degrees Celsius).

What to try first

  • Check food temperatures and move food to another cold place if it is warming.

Safety: If water is reaching outlets, cords or the floor near anything electrical, switch off the breaker before you touch anything, and shut off the water to the appliance.

How urgent is it?

At least TODAY. fixRAgent treats this code as needing attention today. It points at water where it should not be, overheating, a combustion or ignition safety shutdown, food that may be warming, or a wiring problem. This is fixRAgent’s reading, not the manufacturer’s. A photo can raise it — water near wiring, scorch marks, a gas smell — but a code never lowers what the photo shows.

Who to call

Appliance repair. Have the model and serial numbers from the label ready — a photo of the label works.

Recalls and manuals

Check whether your model is under a safety recall on the U.S. Consumer Product Safety Commission’s site: cpsc.gov/Recalls. Your owner’s manual is on LG’s support site; search it with the model number from the label.
