What it means

C462 is GAS LEAK error. The unit is stopping or limiting operation because that reading or component cannot be trusted. Manual trigger: C462 means GAS LEAK error.

Urgency

Likely causes

  1. Actual R-32 refrigerant leak at a flare joint, line set, or coil
  2. Recent installation or service issue involving the refrigerant circuit
  3. Leak-detection or control circuit fault after the space is verified safe
  4. Outdoor PBA interpretation fault after leak checks are complete

Homeowner fix

Turn the system off, ventilate the room, avoid flames, sparks, and smoking, do not add refrigerant, and do not reset the unit back into normal heating or cooling. Expected result: the system stays off until a licensed technician verifies the refrigerant condition.

When to call a pro

Call a licensed HVAC technician before using the system normally again. Tell them the display is Samsung C462 GAS LEAK error on an R-32 system.

Repair vs replace

A minor leak repair may be reasonable, especially under warranty. If the diagnosis involves a coil, buried line set, compressor damage, or repeated refrigerant loss, compare the quote with replacement.
