How to Install Evaporator Fan WP67006337 in a Whirlpool Refrigerator
Before You Replace the Evaporator Fan
The evaporator fan moves cold air across the evaporator area and into the refrigerator air paths. When that fan does not run right, the refrigerator may cool unevenly. The freezer may feel different from the fresh food section. You may also hear odd noises near the back freezer wall.
Before you remove panels, make sure the refrigerator has power and the controls are set correctly. Also check that the doors close fully. A bad door seal or blocked vent can cause cooling trouble that looks like a fan issue.
Do not replace the fan just because the refrigerator is not working properly. That symptom can come from several causes. The fan is one possible cause, not the only one. You still need to inspect the freezer area and listen for fan operation.
You should also confirm the part number before purchase. Use the full model number from the refrigerator tag. The tag may sit inside the fresh food section, near a side wall, ceiling, or frame area. If you cannot find it, check your owner paperwork.
Safety First
Unplug the refrigerator before you start. You will work near electrical connectors and moving parts. Power must stay off until the fan is installed and panels are secure.
Move food out of the freezer area before you remove the inside rear panel. Place frozen food in a cooler if needed. Keep towels nearby, since frost may melt while you work.
Wear work gloves if the freezer panels have sharp edges. Some metal edges can cut your fingers. Safety glasses also help if frost, clips, or debris fall during removal.
Do not use heat guns, open flames, or high heat near plastic liners. If frost blocks access, let it soften at room temperature. You can use towels to catch water. Keep water away from wiring and connectors.
If you see damaged wiring, burned connectors, or signs of heavy overheating, stop the repair. That problem needs more diagnosis before you install a new fan.
Tools and Supplies You May Need
You do not need a large tool kit for most evaporator fan work. Still, you should gather everything before you start. That prevents open freezer time from dragging out.
Common tools include:
- Phillips screwdriver
- Nut driver set
- Small flat screwdriver
- Work gloves
- Towels
- Small container for screws
- Cooler for frozen food
- Phone or camera for reference photos
Your exact fasteners may vary by model. Do not force a screw with the wrong tool. If a driver slips, change tools before you strip the screw head.
Take photos before you unplug wires or remove parts. Photos help during reassembly. They also help you spot whether a wire routes behind a clip, panel, or air duct.

What the Evaporator Fan Does
Your refrigerator does not cool only by making cold air. It must also move that cold air. The evaporator fan handles much of that job.
The evaporator area sits behind an inside freezer panel on many refrigerators. The fan pulls air across the cold evaporator area. Then it pushes that air through designed air channels.
When the fan works well, cold air reaches the right places. Temperatures stay more even. The compressor and sealed system can do their job without fighting poor airflow.
When the fan slows, sticks, or stops, airflow drops. The refrigerator may run longer. Some areas may warm up. You may notice weak cooling, noise, or frost patterns that seem unusual.
The fan does not control every cooling problem. It works with the control system, door switches, temperature sensors, compressor, and defrost system. That is why a quick inspection matters before replacement.
Signs the Evaporator Fan May Be the Problem
A Whirlpool refrigerator not working properly can point toward airflow trouble when certain signs appear together. Look for patterns, not one clue by itself.
Possible fan-related signs include:
- Weak airflow from vents
- Uneven temperatures between compartments
- Noise from the freezer back wall
- No fan sound when cooling should run
- Frost or ice near the fan area
- Food softening while the refrigerator still runs
A fan blade can also hit frost or a loose panel. That may create a scraping, ticking, or buzzing sound. The fan motor may still be good in that case. You need to clear the cause and inspect the fan area.
If the fan area is packed with frost, you may have a defrost issue. Replacing the fan may not solve that. The fan can only move air through open paths.
Quick Checks Before You Open the Freezer Panel
Start with the simple checks. They take a few minutes and can save you from replacing a good part.
Make sure the refrigerator is plugged in. Check that the controls are not set too warm. Confirm the doors close and seal well. Look for packages blocking vents inside the freezer or fresh food section.
Listen near the freezer area while the refrigerator is running. Some models stop the fan when the door opens. If that happens, the door switch may need to be held closed for testing. Do not put fingers near the fan while power is on.
If you hear the compressor running but feel weak airflow, the evaporator fan area deserves attention. If nothing runs at all, the problem may not be the fan. You may need broader diagnosis.
Check for frost buildup on the inside freezer rear wall. A light frost pattern can be normal. A thick snow-like buildup can block airflow and hide a defrost problem.

What to Check After Installation
After you install the fan, check three things: sound, airflow, and temperature trend. Do not judge the repair after only five minutes.
First, listen near the freezer section. A smooth fan sound is normal. Scraping, clicking, or buzzing may mean the blade hits ice, wiring, or a panel.
Next, feel for airflow at vents. Airflow may vary by cycle, but it should improve once the fan runs. Keep doors closed as much as possible.
Then watch temperature over the next several hours. Refrigerators need time to recover after the doors stay open during repair. Warm food loads can also slow recovery.
If the refrigerator still is not working properly after a full cooling period, the fan may not be the only issue. You may need to check controls, sensors, defrost parts, vents, or sealed system performance.
Common Mistakes to Avoid
Many evaporator fan problems after repair come from small mistakes. You can avoid most of them with careful handling.
Do not force the rear panel. Hidden ice or fasteners can hold it in place. Find the cause before prying hard.
Do not leave wires loose near the blade. A loose wire can make noise or stop the fan.
Do not mix up screws. Some screws may look close but fit different spots. Keep them grouped as you remove them.
Do not ignore heavy frost. A frozen fan may be a symptom, not the root cause. If frost returns fast, inspect the defrost system.
Do not run the refrigerator with panels missing for normal use. The panels help direct airflow. Without them, cooling can act strange.
Do not assume a listed model is enough by itself. Match your full model number and part details before ordering.
Troubleshooting If the New Fan Does Not Run
A new fan that does not run can be frustrating. Stay calm and recheck the basics.
First, confirm the refrigerator has power. Then check whether the door switch affects fan operation. Some fans stop when the freezer door opens. You may need to close the switch to test fan action.
Next, unplug the refrigerator and inspect the connector. A connector that looks attached may not be fully seated. Check for bent pins, loose wires, or damaged locking tabs.
Look for ice or a panel pressing against the blade. Even a new fan cannot run if something blocks it.
If wiring and clearance look good, the issue may sit outside the fan. Controls, sensors, switches, and other circuits can affect fan operation. At that point, you need deeper diagnosis.
Use Whirlpool’s Service & Support resources for model-related support documents when available.
When You Should Stop and Get Help
You can handle many fan replacements at home. Still, some signs should make you pause.
Stop if you see burned wires, melted connectors, or damaged insulation. Those signs can point to electrical trouble. Replacing the fan without fixing wiring can be unsafe.
Stop if the evaporator area is buried in heavy ice. That can point to a defrost problem. The fan may fail again if ice returns.
Stop if panels will not fit back correctly. A misfit panel can block air or strike the fan.
Stop if the refrigerator has no signs of life after power returns. That problem needs a broader check.
A careful stop is better than a rushed repair. You protect the refrigerator and your food.
Repair Decision Matrix
Use this table to decide your next move before and after fan replacement.
| What you see or hear | What it may mean | Best next step |
|---|---|---|
| Fan blade hits ice | Frost blocks fan movement | Thaw safely and inspect for repeat frost |
| Fan is silent, but compressor runs | Fan, wiring, switch, or control issue | Check connector and door switch behavior |
| Rear freezer wall has heavy frost | Possible airflow or defrost issue | Do not treat fan as the only cause |
| New fan scrapes after install | Blade, wire, or panel contact | Unplug and check clearance |
| Refrigerator cools better after repair | Airflow likely improved | Monitor temperatures for a full day |
| No improvement after repair | Another system may be involved | Continue diagnosis before buying more parts |
This matrix helps you avoid part swapping. It also helps you judge whether WP67006337 solved the real airflow problem.
Maintenance Tips After Fan Replacement
You cannot prevent every fan failure. You can still reduce stress on the refrigerator.
Keep freezer vents clear. Do not pack food tight against the rear wall or air openings. Air must move to cool the whole space.
Clean door gaskets when they get sticky or dirty. Poor sealing can bring in warm, moist air. Moisture can add frost inside the freezer.
Do not leave doors open while loading groceries. Long door openings raise temperature and humidity. That makes the refrigerator work harder.
Check for strange noises early. A light tick can become a louder scrape if ice or a loose wire reaches the blade.
Watch cooling performance after power outages. Food loads and door openings can hide cooling problems. Give the unit time, but do not ignore a long warm-up.
Cost and Ordering Notes
No price is provided here because prices change often. Do not trust a repair article that invents a price. Check the current part listing before you buy.
When ordering, use the OEM number WP67006337 and your full Whirlpool model number. Make sure the seller lists the correct part and return terms.
Avoid choosing parts by photo alone. Many small fan motors look similar. Connector shape, mounting style, and blade setup matter.
Keep your order receipt until the repair is complete. Also keep the old fan until the new fan works. If you need support, those details can help.
