How to Install Humidity Control WP67005864 in a Whirlpool Refrigerator
If your Whirlpool refrigerator is not working properly, the humidity control may need attention. This small control helps manage moisture in the fresh food area. When it fails, food storage can suffer. You may see produce dry out too fast, drawers feel too damp, or the refrigerator act in ways that seem hard to trace.
How to Install Humidity Control WP67005864 is a job many careful DIY owners can handle. The work is not the hardest refrigerator repair, but it does need patience. You must protect the liner, shelves, bins, and wiring as you work.
This guide uses only the facts listed for Whirlpool humidity control WP67005864. It applies to the listed compatible models: 596.73503200, 596.73503201, AFD2535DEB, AFD2535DES, and AFD2535DEW. If your model tag shows a different number, confirm fit before you order or install the part.
For brand documents, you can use Whirlpool Owner Manuals and the Whirlpool Product Help Library when you need model-specific details.
Before You Start
A refrigerator humidity control affects how air and moisture move around the crisper area. In many refrigerators, the control lets you change the vent opening near the drawer. Some designs use a slider, lever, cover, or small damper. The exact trim can vary by model.
Do not force any trim piece. Refrigerator liners and drawer frames can crack when you pry too hard. Plastic tabs can also break if you pull in the wrong direction. Slow work prevents most damage.
The install difficulty is Medium. Plan on 30 to 60 minutes. That time includes clearing food, removing shelves or drawers, reaching the control, swapping the part, and testing movement.
You do not need advanced sealed-system skills for this repair. You should not touch refrigerant lines, sealed tubing, or compressor parts. You are working inside the fresh food section, near drawers and trim.
Still, you must treat the refrigerator like an electrical appliance. Unplug it before you remove parts near a control, wiring, or moving air door. If you cannot reach the outlet, turn off power at the breaker.
Confirm the Part and Model First
Check the model tag inside your Whirlpool refrigerator before you begin. Many model tags sit on an inner wall, ceiling, frame, or side panel inside the fresh food section. Write the model number exactly as shown.
This article uses humidity control WP67005864 for these models:
| Compatible model |
|---|
| 596.73503200 |
| 596.73503201 |
| AFD2535DEB |
| AFD2535DES |
| AFD2535DEW |
Match every letter and number. Do not rely on looks alone. Two controls can look close but mount in different ways. A wrong control may not fit the track, trim, or drawer frame.
Also check the old part area before you open the new package. Look for cracked tabs, a jammed slider, loose trim, or a missing cover. If another broken piece holds the control, the new humidity control may not stay secure.
Keep the new WP67005864 near the old part while you work. Compare shape, mounting points, and movement. If the new part does not match the old one, stop before installing it.
Symptoms You May Notice
The provided symptom is broad: refrigerator not working properly. That can mean many things. A humidity control issue often shows up near food quality and drawer performance.
You may notice produce wilting early. Leafy greens may dry out sooner than normal. Some items may collect too much moisture. The drawer area may feel wrong compared with past use.
You may also notice the control no longer moves. A slider may feel stuck, loose, or disconnected. The setting may change by itself when you open and close the drawer. A control cover may hang out of place.
A humidity control will not fix every cooling problem. It will not repair a bad compressor, failed fan, blocked drain, or sealed-system fault. If the whole refrigerator is warm, check basic cooling issues first.
Use this repair when the control itself is broken, stuck, missing, or not changing position. If you are not sure, inspect the part closely before removing it.
Tools and Supplies
Use basic hand tools and light pressure. Your exact fasteners may vary, so choose tools that fit the screws in front of you.
Common tools include:
- Phillips screwdriver
- Flat-blade screwdriver or plastic putty knife
- Small container for screws
- Work gloves
- Towel
- Flashlight
- Phone camera for reference photos
A plastic pry tool is safer than a metal screwdriver on trim. If you only have a flat screwdriver, wrap the tip with tape. That lowers the chance of scratches.
Use a towel to protect glass shelves and drawer fronts. Set removed parts on the towel in order. That makes reassembly faster and cleaner.
Do not use power drivers unless you have very good control. Refrigerator trim screws often thread into plastic. Too much torque can strip the hole or crack the mount.
Safety Steps
Unplug the refrigerator before you begin. This protects you while you work near any control area. It also prevents a fan from starting while your hands are inside the cabinet.
Move food to a cooler if the repair may take longer than expected. Keep the doors closed as much as possible. A short repair should not harm food, but warm room air enters fast.
Remove heavy glass shelves with two hands. Glass can be slippery when cold. Set each shelf on a flat, safe surface away from your feet.
Do not pull on wires. If your model has a wire connector near the control, release the connector by its body. Do not tug on the wire leads.
Stop if you see damaged insulation, burned wiring, melted plastic, or broken liner material. Those problems need closer inspection before you install a new part.

Common Mistakes That Damage the Repair
Most failed installs come from rushing. The part is small, but the plastic around it matters.
Do not pry against the refrigerator liner. The liner is not a pry surface. Use the trim edge or tab point instead.
Do not overtighten screws. A snug screw is enough for plastic trim. If the screw spins without tightening, the hole may be stripped.
Do not install the control backward. A reversed slider can block movement or make the setting label wrong.
Do not leave shelves loose. A shelf that is not seated can press on the drawer or control. That can make the new part bind.
Do not skip the test before loading food. Move the control, drawer, and cover while the area is still empty. It is much easier to correct a problem then.
Pitfall Ranking for This Repair
| Rank | Pitfall | Why it matters | Best prevention |
|---|---|---|---|
| 1 | Breaking a plastic tab | The control may not stay mounted | Release tabs slowly |
| 2 | Mixing up trim order | Drawers may not slide right | Take photos before removal |
| 3 | Overtightening screws | Plastic mounts can strip | Tighten by hand only |
| 4 | Skipping model check | The part may not fit | Match the full model number |
| 5 | Ignoring nearby damage | New part may fail to seat | Inspect rails and frame |
This ranking matters because the humidity control sits in a high-use area. You touch the drawer often. A small fit issue can become a daily problem.
The best repair is not just a new part. It is a clean mount, correct orientation, and smooth drawer travel.
When This Part May Not Solve the Problem
A humidity control can help with drawer moisture issues. It will not solve every case where a refrigerator is not working properly.
If the fresh food section is warm, check whether the freezer is also warm. A broad cooling failure often points beyond the drawer area.
If you hear loud fan noise, see heavy frost, or find water pooling, another system may be involved. A blocked air path or drain issue can mimic food storage problems.
If the drawer will not close, inspect the rails, shelf, and drawer body. A broken drawer can hit the control and make it seem failed.
If food freezes in the drawer, check airflow and temperature settings. A humidity control may not be the root cause.
You can still replace a broken or stuck WP67005864. Just keep your expectations clear. The part fixes the control function, not every cooling fault.
Quick Diagnosis Table
| What you see | What it may mean | What to check |
|---|---|---|
| Slider is loose | Control may be broken or unseated | Mounting tabs and face |
| Slider will not move | Control may be jammed | Food debris or cracked trim |
| Drawer hits control | Drawer or shelf may be misaligned | Tracks, shelf seating, cover |
| Produce dries fast | Humidity setting may not hold | Control movement and vent |
| Whole refrigerator warm | Larger cooling issue possible | Power, airflow, cooling system |
Use this table before you replace the part. It can save time and prevent the wrong repair path.
How to Handle Food While You Work
Plan the job when the refrigerator is not packed. A full fresh food section makes access harder. It also raises the chance of dropping food or cracking a drawer.
Move produce to a clean bin or cooler. Keep raw meat away from ready-to-eat foods. Wipe any spills before they reach the drawer rails.
Do not set heavy items on glass shelves you removed. A shelf can crack if weight sits on one unsupported edge.
Use the repair time to clean the drawer area. Sticky residue can make controls and drawer slides feel worse. A clean track helps you judge the new part better.
When you reload the drawer, do not overpack it. Food pressed against the control can block movement. Leave space near vents and slider parts.
Setting the Humidity Control After Installation
Many refrigerator drawers use humidity settings to manage airflow. A closed or higher humidity setting can help leafy produce. An open or lower setting can help fruit that releases moisture.
Use the labels on your Whirlpool refrigerator if they are present. If the labels are worn, make small changes and watch the food over time.
Do not expect instant results. Food moisture changes over hours and days. A working control gives you adjustment, not magic.
If produce still wilts fast, check drawer sealing and food placement. Open bags, damaged produce, and poor storage habits can cause the same result.
If water collects in the drawer, lower the humidity setting if your control allows it. Also check for blocked airflow or wet food packaging.
Maintenance After the Repair
Keep the drawer area clean. Crumbs and sticky spills can jam a slider. A monthly wipe-down helps the control move well.
Do not slam drawers. Impact can loosen trim and tabs. Push drawers straight in until they seat.
Avoid hanging bags over the drawer edge. Plastic bags can catch the control and pull it out of position.
Check the control when you clean the refrigerator. Move it through its range once or twice. It should feel smooth and stable.
If the control feels stiff again, clean the area before replacing more parts. Food residue is common near crisper drawers.
