Direct answer
For the Whirlpool WRT318FZDW top-freezer refrigerator, warm loading, door opening, room heat and recovery are normal; poor seals, airflow and cooling faults are not. First, measure compartment temperatures and door-seal contact.
What this covers
- Whirlpool WRT318FZDW top-freezer refrigerator (WRT318FZDW)
- Whirlpool WRT318FZDW top-freezer refrigerator. Whirlpool’s own specification for this model states no built-in ice maker and no water dispenser (the EZ Connect icemaker kit is sold separately), so dispenser, plumbed ice and water-filter symptoms do not apply to it as sold.
- The specific fault this record addresses: runs constantly or cycles too often
What it does not cover
- ×The same symptom on a different Whirlpool product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The unit has a variable-speed compressor and is behaving as designed
What separates it The refrigerator is relatively new, holds correct temperatures, and simply runs quietly and continuously rather than cycling.
How to confirm Check whether temperatures are actually correct. Continuous low-speed running is more efficient than repeated hard starts and is how most current machines work.
- 2
The condenser coils are dirty
What separates it Constant running alongside temperatures that are drifting up, with visibly dusty coils underneath or behind.
How to confirm Reduced heat rejection means the system must run longer to achieve less. This is the most common real cause and is owner-serviceable.
- 3
Door seals are leaking or the door is being held ajar
What separates it Constant running with condensation or frost near the doors.
How to confirm See door-not-closing.
- 4
Recent loading or frequent opening
What separates it Constant running after a large restock or during a period of heavy use, resolving within a day.
How to confirm This is normal recovery behaviour and does not need intervention.
- 5
Ambient temperature is high, or clearance is inadequate
What separates it Constant running in hot weather, or on a unit installed tight against cabinetry with no ventilation gap.
How to confirm Check the manufacturer's stated clearance requirements at the top, back and sides.
- 6
A defrost failure is forcing the system to work through ice
What separates it Constant running with frost accumulating and cooling declining.
How to confirm See frost-ice-buildup.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether temperatures are actually correct — this decides whether constant running is a problem at all.
- The age and type of the unit, since variable-speed compressors run continuously by design.
- Whether the condenser coils are dusty and whether clearance meets the manual's requirement.
- Whether there has been a large restock or unusually heavy use recently.
Measure both compartment temperatures before treating constant running as a fault
ReversibleA modern variable-speed compressor running continuously while holding correct temperatures is working as designed.
Clean the condenser coils
ReversibleThis is the most common genuine cause and is routine owner maintenance.
Confirm the manufacturer's clearance requirements at top, back and sides
ReversibleA unit boxed tightly into cabinetry cannot shed heat properly.
Check the door seals and that nothing holds a door ajar
ReversibleA continuous small air leak forces continuous running.
Allow a day after any large restock before judging
ReversibleRecovery from a big load legitimately takes many hours of continuous running.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- WRT318FZDW. Whirlpool WRT318FZDW top-freezer refrigerator. Whirlpool’s own specification for this model states no built-in ice maker and no water dispenser (the EZ Connect icemaker kit is sold separately), so dispenser, plumbed ice and water-filter symptoms do not apply to it as sold.
- Type — TOP-FREEZER (no dispenser, no ice maker)
- An entry TOP-FREEZER Whirlpool that ships with NO through-door dispenser AND NO factory ice maker (verified). Dispenser and ice-maker symptoms do not apply — you use ice trays and fill water by hand. Top-freezers are the simplest, most reliable layout.
- Optional ice-maker kit
- Some WRT models accept an add-on ice-maker kit, but as shipped none is installed — 'ice maker not working' means there is no ice maker, not a fault.
- Cooling
- A single cooling system, freezer on top. A warm fridge with a cold freezer is usually the down-vent to the fridge blocked by packed food or iced from a defrost issue — clear it and avoid overpacking the top shelf. Clean the condenser coil periodically.
- Symptom boundary
- This record covers Whirlpool WRT318FZDW top-freezer refrigerator when it runs constantly or cycles too often. A different symptom on the same hardware, or this symptom on a different Whirlpool product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Move perishable food and stop for severe heat at the compressor, smoke, or an electrical odour.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Whirlpool Product Help publishes this as "Product Help". Official Whirlpool product help; this key exists so the top-freezer refrigerator cites Whirlpool's Top Freezer articles. What that article does not carry is the model boundary — it is written for a product line, and WRT318FZDW is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
How do I make ice in my Whirlpool WRT318FZDW?+
With ice trays — this entry top-freezer ships with no factory ice maker and no dispenser, so there is nothing automatic to troubleshoot for ice or water. Some versions can take an optional add-on ice-maker kit if you want automatic ice, but out of the box you fill trays and put them in the top freezer. It is not a fault, just the model's simple configuration.
My new refrigerator never seems to shut off — is that bad?+
Usually not. Most current refrigerators use variable-speed compressors that are designed to run almost continuously at low speed, because that is more efficient than repeatedly starting and stopping. The question that matters is whether the temperatures are correct — if they are, continuous running is the machine working as intended rather than a fault.
It runs constantly and the food isn't as cold as it should be.+
Constant running combined with poor temperatures is a real problem, and dirty condenser coils are the most common cause. The condenser has to shed heat into the room, and when it is matted with dust the system runs longer while achieving less. Cleaning the coils is routine owner maintenance.
Does this answer apply to every Whirlpool model?+
No. It is scoped to WRT318FZDW. Whirlpool WRT318FZDW top-freezer refrigerator. Whirlpool’s own specification for this model states no built-in ice maker and no water dispenser (the EZ Connect icemaker kit is sold separately), so dispenser, plumbed ice and water-filter symptoms do not apply to it as sold.
What should I record before troubleshooting runs constantly or never shuts off?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing runs constantly, never shuts off. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Protect food and stop for severe heat, smoke or electrical odor.
