How to Clean the Condenser Coils on a Whirlpool WRQA59CNKZ Refrigerator — Step-by-Step Instructions
Step-by-step instructions for the Whirlpool WRQA59CNKZ (side-by-side refrigerator, counter-depth, 20 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.
Whirlpool WRQA59CNKZ notes & error codes
Counter-depth models trade cabinet depth for a built-in look, and the reduced space behind the liner makes coil cleaning more consequential than on a standard-depth machine.
| Code | What it means |
|---|---|
| Diagnostic mode | Door-switch sequence enters service mode |

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 →
