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.

| Code | What it means |
|---|---|
| No display codes | Simple electronic or mechanical control, diagnosis is by measurement |
| Cold control | Thermostat switches the compressor directly. Test it before suspecting the sealed system |
