How to Clean the Condenser Coils on a LG LRSXS2706S Refrigerator — Step-by-Step Instructions
Step-by-step instructions for the LG LRSXS2706S (side-by-side refrigerator, 26.8 cu ft). Parts and access points can differ slightly by production year — the steps below cover the common layout for this platform, and the model notes flag its quirks.
Unplug the fridge (contents are fine for 30 minutes with doors shut). Don’t stab at the thin condenser fins with hard objects.
Tools
- Coil brush (long flexible bottle-brush, ~$10)
- Vacuum with crevice tool
- Flashlight
Parts
- None — pure maintenance
Step by step
-
1 Find the coils
Newer fridges: behind the front toe-grille or accessed from the lower rear panel. Older fridges: the black grid on the back wall. The flashlight will show you a felt blanket of dust if it’s overdue.
-
2 Brush and vacuum
Work the coil brush through the coils and fan area while vacuuming what it dislodges. Get the condenser fan blades too — dusty blades move noticeably less air.
-
3 Do the floor and grille
Vacuum the drain pan area and the toe-grille itself; pet hair drifts back fast if you leave a supply nearby.
-
4 Restore airflow clearance
When pushing the fridge back, keep a couple of inches of breathing room behind and above it — a fridge sealed into its alcove runs hot no matter how clean the coils are.
-
5 Repeat on a schedule
Yearly minimum; every 6 months with shedding pets. Put it on the same calendar entry as your dryer vent.
LG LRSXS2706S notes & error codes
Always pull the model and serial and check sealed-system warranty coverage before quoting a compressor on any LG linear-compressor refrigerator. The compressor part is covered to 10 years but the labour only to 5 (1 year on pre-2022 units), so quote the labour honestly rather than promising a free repair.
| Code | What it means |
|---|---|
| Er FF | Freezer evaporator fan fault |
| Er rF | Refrigerator fan fault |
| Er dH | Defrost heater circuit fault |
| Er CF | Condenser fan fault |
| Er CO | Communication error between main and display boards |
Full details for this machine — common problems, causes, and costs — are in the LG LRSXS2706S repair guide. The general version of these instructions is here.
If the fridge still runs constantly or struggles to hold temperature with clean coils, a real fault (defrost, gasket, charge) is in play — see the runs-constantly cost guide and get a diagnosis. If you'd rather skip it entirely, find a refrigerator repair pro near you →
