Do not match parts by sight alone. Many fans look close but differ in mount, plug style, or airflow path. Use your full model number from the rating label. Then compare it with the part listing and Whirlpool support resources.
If your model is not listed above, stop and verify fit another way. A wrong fan can mount poorly, rub, fail early, or leave the unit unsafe.
What the Cooling Fan Does
A cooling fan moves air where heat needs control. It may cool a control area, help vent warm air, or protect nearby parts from heat stress. The exact design can vary by model.
When the fan works well, air moves without grinding, scraping, or hesitation. The fan blade spins freely. The motor does not smell burnt. The wiring connector seats firmly. The mounting points hold the fan square.
When the fan fails, you may see one clear issue. You may also see vague behavior, such as plumbing not working properly. That broad symptom makes diagnosis important.
A failed fan can cause heat buildup. Heat can stress nearby wiring, controls, insulation, and plastic parts. You should not ignore a fan that does not run when the unit calls for it.
Signs the Fan May Be Bad
You only supplied one symptom: plumbing not working properly. That does not prove the fan failed by itself. Use these checks to narrow the issue without inventing a diagnosis.
Look for these fan-related clues:
- The fan blade does not spin freely by hand.
- The fan rubs the housing or nearby parts.
- The fan makes a scraping, buzzing, or grinding sound.
- The fan area has a burnt smell.
- The fan connector looks loose, damaged, or overheated.
- Airflow seems weak where the fan should move air.
- The fan runs sometimes, then stops without a clear reason.
One clue is not always enough. For example, a fan may not run because the control does not send power. A wire may be loose. A safety switch may stop operation. You should inspect the full area before replacing the part.
Whirlpool’s Product Help Library can help you compare symptoms with model-specific support topics.
Safety First
Do not start this repair while the unit has power. Disconnect power at the plug or breaker before you touch wiring. If the appliance connects to a hardwired circuit, use the breaker. If you cannot confirm power is off, stop and call a qualified technician.
Use these safety habits:
- Turn power off before removing panels.
- Let hot parts cool before touching the area.
- Wear work gloves around sharp metal.
- Keep children and pets away from the work space.
- Use a stable work light.
- Avoid wet floors while working near electrical parts.
- Take photos before you unplug anything.
- Do not pull wires by the wire body.
- Hold connectors by the plastic housing.
Some panels have sharp edges. Move slowly when you reach inside. If you feel resistance, stop and look. Hidden screws, tabs, and brackets can break if forced.
Never bypass a safety device to test the fan. That can create shock, burn, or fire risk.
Tools and Supplies
Your supplied facts did not include a tool list. Use common repair tools and adjust by model.
You may need:
- Phillips screwdriver
- Flat screwdriver
- Nut driver set
- Work gloves
- Flashlight or headlamp
- Painter’s tape for labels
- Small container for screws
- Phone camera for reference photos
- Multimeter, if you know how to use one safely
Do not use power tools unless you control torque well. Small screws can strip fast. A hand tool gives better feel.
You also need the replacement Cooling Fan WPW10016550. Keep it in the package until you confirm the old fan location, connector, and mounting style.
Confirm the Model Number
Find the full model number before you order or install the fan. The supplied compatible models are GMC305PDB07, GMC305PDB6, GMC305PDQ07, GMC305PDQ6, and GMC305PDS07.
Check the model label on your unit. Do not rely on the manual cover, sales receipt, or a family member’s memory. Small suffix changes can matter.
Write the model number down exactly. Include every letter and number. Then compare it with your part source and Whirlpool documentation. Whirlpool’s Service & Support manuals page can help you find model documents.
If the label is hard to read, take a close photo with good light. Zoom in and verify each character. A single wrong character can lead to the wrong part.

Common Mistakes to Avoid
A medium repair can go wrong through small errors. Most problems come from rushing.
Avoid these mistakes:
- Ordering by photo instead of model number.
- Forgetting to shut off power.
- Pulling wires instead of connectors.
- Mixing screw locations.
- Pinching the fan harness under a panel.
- Leaving insulation in the blade path.
- Installing the fan crooked.
- Ignoring melted connectors or burnt wiring.
- Testing with panels still off when the design needs them installed.
- Assuming the fan is bad without inspection.
The biggest mistake is forcing the part. A correct fan should line up without major pressure. If it does not fit, stop and verify the part and model.
Troubleshooting After Installation
If the unit still has plumbing not working properly after the repair, do not keep running it without checks. The fan may not have been the only problem.
Use this quick path:
| What you notice | What to check next |
|---|---|
| Fan does not run | Power, connector, wiring, control signal |
| Fan scrapes | Mount alignment, blade clearance, loose debris |
| Fan vibrates | Mount screws, cracked bracket, crooked seating |
| Burning smell | Wiring, connector, nearby heat damage |
| Unit still acts wrong | Original diagnosis, related controls, airflow path |
Turn power off before you recheck the fan area. A loose connector may be easy to fix. Damaged wiring is different. If you see melted plastic or exposed wire, stop and get qualified help.
A new part cannot fix a bad connector, failed control, or blocked air path. Treat the fan as one part of the full system.
Repair Decision Matrix
Use this matrix before you decide whether to install the fan yourself or call a technician.
| Situation | Best choice | Why it matters |
|---|---|---|
| You can reach the fan with basic panel removal | DIY may be reasonable | The job stays within medium difficulty |
| Wiring looks clean and undamaged | DIY may be reasonable | The repair stays part-focused |
| Connector is melted or brittle | Call a technician | Heat damage can spread beyond the fan |
| You cannot confirm model fit | Stop and verify | Wrong parts waste time and can cause damage |
| Fan area is hard to reach | Consider a technician | Tight spaces raise breakage risk |
| You smell burning after repair | Shut power off | Continued use can be unsafe |
| You feel unsure around wiring | Call a technician | Electrical work needs confidence and care |
This is not about pride. A good repair means the unit works safely after you close it. If the job moves beyond the fan, bring in help.
How to Handle the Old Fan
Do not throw the old fan away until the new one tests well. Keep it nearby during the first test. You may need it for comparison.
Place the old fan in the new part box. Mark it as old. That prevents mix-ups if both parts sit on the bench.
After the unit passes testing, recycle or discard the old fan based on local rules. Do not reuse a fan that binds, smells burnt, or has a damaged connector.
If you plan to contact support, keep photos of the old fan, model label, and connector. Clear photos make support faster.
When the Fan Is Not the Root Cause
A cooling fan may be blamed when another issue caused the symptom. Since the supplied symptom is broad, keep an open mind.
The fan may be fine if:
- It spins freely.
- It runs when called.
- The connector is tight.
- No rubbing or vibration appears.
- Airflow seems normal.
- No heat damage is visible near the fan.
Other parts may affect operation. The issue may involve wiring, controls, switches, blocked airflow, or another system fault. Do not replace extra parts without proof.
A multimeter can help confirm power at the connector, but only use one if you know safe testing methods. Live voltage checks are not beginner work.
Maintenance After Replacement
A new cooling fan should not need much attention. Still, you can help it last.
Keep the area around the unit clean. Dust and debris can collect near vents and panels. Poor airflow makes the fan work harder.
Check for new noises during normal use. A light airflow sound can be normal. Scraping, buzzing, or rattling deserves attention.
Do not block vents or airflow paths. Panels, shields, and covers guide air. Missing or loose covers can change how heat moves.
If you remove panels later for another repair, inspect the fan harness. Make sure it stays clipped and clear of moving parts.
