LG Refrigerator SS Error Code
Pantry or specialty drawer sensor fault
What this error means
SS appears on LG models with pantry drawers, Craft Ice, or convertible zones when a secondary temperature sensor stops reporting—often the drawer was left open or the harness was disturbed during cleaning.
How SS is detected
When SS appears on a LG refrigerator, the control board has confirmed that water did not leave the machine within the programmed drain window. On LG LRMVS3006S, LG LRFVS3006S, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most SS calls are resolved without parts: close all specialty drawers until seals compress evenly. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If SS returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Convertible drawer left cracked open
- Sensor unplugged during drawer removal for cleaning
- Excessive ice in a multi-zone drawer blocking the sensor air path
- Failed zone damper motor related to the same sensor circuit
Step-by-step fixes
- 1Close all specialty drawers until seals compress evenly
- 2Remove drawer, inspect rear harness for loose plug
- 3Set zone to a mid temperature and wait two hours
- 4Power-cycle after confirming drawers seat on rails fully
When to call a technician
SS with properly seated drawers points to zone sensor or damper motor replacement.
Affected models
- LG LRMVS3006S
- LG LRFVS3006S
- LG LMXS28626S
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use refrigerators to prevent SS from lint and food debris buildup.
- Record when SS appears in the cycle and whether it clears after a 60-second power reset on your LG refrigerator—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for SS; LG uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting SS; reversed plugs on pumps and valves cause immediate repeat faults.
