Is tt on a LG refrigerator an emergency?

Usually not an emergency. If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.

What tt means

“The tt code indicates a water tank fault.”

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

Where tt fits

Next to tt in LG’s table: rF (The rF code indicates a fault with the refrigerator fan) and C1 (communication error between the dispenser and the display).

What to try first

  • Check the water tank is present and seated correctly.

Safety: If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.

How urgent is it?

At least THIS WEEK. fixRAgent treats this code as a this-week repair: the appliance has reported a fault, but the code alone does not point at a safety hazard. 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.
