LG Refrigerator SS Error
SS is one of the codes LG documents with a meaning but no owner procedure: its US consumer list names the fault and stops there. FixSignal could not verify a second meaning for SS from publicly accessible LG sources, so this page prints the consumer-documented meaning only — and says so on the page.
What to check first
- Read the code exactly: SS (segment-display form 55).
- LG's consumer list gives SS no owner procedure — no published check, adjustment or reset exists for this code.
- Do not borrow the Er family's reset — SS is not among the codes in LG's Er guide.
- To confirm the meaning for your model, check the model-specific manual or confirm with LG support; request LG service with the model number.
SS is a water tank sensor code in LG's US digital and analog list: an issue that occurred in detecting the water tank temperature, which LG says will cause a reduction in the appliance's performance. On a seven-segment display the code renders as 55 — LG's list illustrates it with a 55 display photograph. LG publishes no consumer troubleshooting procedure for SS: its analog list heads its malfunction codes with a request-service instruction, and SS does not appear in LG's US Er guide, so no Er reset is published for it either. One note, printed plainly: FixSignal could not verify a second meaning for SS from publicly accessible LG sources. To settle what SS means on your specific refrigerator, check the model-specific manual or confirm with LG support.
Safety first
- SS is a sensor-detection fault. LG provides no owner troubleshooting procedure for it in the cited consumer source — there is no published check, adjustment or reset for this code. Do not open panels chasing it.
- Stop condition: stop using the machine and unplug it — and do not run it again until it has been checked — if you smell burning, see smoke, find damaged electrics (a scorched plug, a melted or cut cable), or water is leaking in quantity.
Common causes
The documented fault: water tank temperature detection
LG's US consumer list defines SS as an issue in detecting the water tank temperature, and states that it causes a reduction in the appliance's performance. LG gives no deeper breakdown for SS — no named part beyond the detection function, and no cause list.
One documented meaning
LG's publicly accessible US consumer guide defines SS as a water-tank temperature-detection issue. FixSignal could not verify a second meaning for SS from publicly accessible LG sources, so this page prints the one documented meaning and no other. If the meaning matters for a repair, confirm it for your specific model in the model-specific manual or with LG support.
Step-by-step checks
- Read the display exactlyOn a seven-segment display SS renders as 55 — LG's list illustrates the code with a 55 display photograph. Record the form you saw, exactly as shown.
- Do not borrow a resetSS does not appear in LG's US Er guide, so no Er-family reset is published for it, and this page does not borrow one. The analog list's instruction for its malfunction codes is to request service.
- Confirm the meaning for your model, then request serviceLG's consumer documentation gives SS one meaning — the water tank temperature detection above. To confirm what SS means on your specific model, check the model-specific manual or confirm with LG support; then request service with the code and the model number.
When to call a technician
SS is a service code in LG's consumer documentation: a documented meaning, no published owner procedure. Quote the exact code (SS, or 55 as displayed) and the model number; if the meaning matters for the repair, the technician can confirm it against the model-specific documentation.
Model differences
| What you have | What changes |
|---|---|
| Segment displays | SS can render as 55 — LG's list illustrates the code with a 55 display photograph. Same code, two forms: LG documents them together in one entry. |
| Er form | LG's US consumer Er guide does not list SS among its 27 codes, so no Er SS meaning is documented in LG's consumer sources. This page makes no claim about an Er form beyond that. |
| Confirming your model | LG's lists are model- and region-dependent. To settle SS for a specific refrigerator, check the model-specific manual or confirm with LG support. |
One-page checklist — SS
- Code read exactly (SS / 55)
- No reset attempted — none is published for SS
- Meaning confirmed for your model (model-specific manual or LG support)
- LG service requested with the code and model number

Frequently asked questions
What does SS mean on my LG refrigerator?
In LG's US consumer documentation: an issue in detecting the water tank temperature, which LG says reduces the appliance's performance. That is the only meaning LG's publicly reachable documentation supports. To confirm the meaning for your specific model, check the model-specific manual or confirm with LG support.
Is there another meaning for SS?
Not one FixSignal could verify. LG's publicly accessible US consumer guide defines SS as a water-tank temperature-detection issue, and FixSignal could not verify a second meaning for SS from publicly accessible LG sources. To confirm the meaning for your specific model, check the model-specific manual or confirm with LG support.
Can I reset SS?
No reset is published for SS in any LG source used: it is not among the codes in LG's US Er guide (where the family reset appears), and the analog list's instruction for its fault codes is to request service.
