How to Install Screw 240578902 in a Frigidaire Refrigerator
Before You Start
A screw replacement sounds small, but you still need to treat it like a real repair. Your refrigerator has sharp edges, electrical parts, moving air paths, and fitted panels. If you rush, you can strip the hole, crack plastic, bend a bracket, or trap wiring.
Start by finding the exact spot where screw 240578902 belongs. Do not guess. Look for a matching empty screw hole, loose part, missing fastener, or part that moves more than it should. If you removed the old screw earlier, compare its location with your notes or photos.
Use good lighting. A refrigerator cabinet can hide screw holes behind drawers, covers, liners, trim, or brackets. Remove only the parts needed for access. Keep every removed screw separate from screw 240578902, so you do not mix hardware during reassembly.
This repair has a medium difficulty level. Plan for 30 to 60 minutes. The job may take less time if the screw location is open. It may take longer if you must remove shelves, panels, or covers to reach the mounting point.
Confirm the Part and Model Fit

Check your refrigerator model tag. On many refrigerators, the model tag sits inside the fresh food section, near a side wall, ceiling area, or frame. Some units place it behind a lower drawer or near the cabinet opening. Read the full model number, not just the first few digits.
If your model does not match the listed models, stop and verify the part before installing it. A screw can vary by thread, length, head style, or intended mounting surface. The wrong screw can bite at first, then strip the hole or fail to hold.
Tools and Supplies You May Need
Use basic hand tools unless the access area needs more work. Do not use power tools for final tightening. A drill or driver can over-tighten fast and damage plastic or thin metal.
You may need:
- Phillips screwdriver
- Flat blade screwdriver
- Nut driver set
- Work gloves
- Flashlight or headlamp
- Small container for removed screws
- Painter’s tape for labeling parts
- Phone camera for reference photos
- Towel to protect shelves or the floor
Choose the screwdriver or driver that fits the screw head snugly. A loose bit can cam out and chew the head. Once the head strips, removal becomes harder than the original repair.
Safety Steps for Refrigerator Screw Installation
Unplug the refrigerator before you work near panels, covers, wiring, controls, fans, or any hidden electrical area. If the screw location is on a removable trim piece with no nearby wiring, you still need to work with care. When in doubt, disconnect power first.
Move food away from the work zone. Put chilled items in a cooler if the door will stay open for a while. Keep shelves and drawers on a soft surface. Glass shelves can chip if you set them on tile or concrete.
Wear gloves if you must reach behind panels or into lower cabinet areas. Sheet metal edges can be sharp. Plastic liners can also cut your hand if cracked or broken.
Do not force panels. If a cover will not move, look for hidden screws, tabs, or clips. Forcing a refrigerator panel can break a tab and create a new problem.

What the Screw May Affect
A screw can support many refrigerator parts. Without the exact service diagram in front of you, you should not assume its location. Still, the repair logic stays the same.
A missing screw may let a panel vibrate. It may let a bracket sag. It may allow a cover to shift into an air path. It may leave a drawer rail loose. In some cases, movement from one part can affect another nearby part.
That is why your inspection matters. You are not just “putting in a screw.” You are restoring the part it holds to the right position.
Watch for these clues:
- A panel feels loose when touched
- A rail or support moves under load
- A cover does not sit flat
- A rattling noise starts after door movement
- A shelf, bin, or drawer does not align well
- A part has one screw installed and one hole open
- The refrigerator works, but something inside seems unstable
If the refrigerator is not cooling, leaking, sparking, or showing a control problem, a screw alone may not solve it. Treat those issues as separate diagnostic work.
Common Mistakes to Avoid
Small hardware repairs fail when the screw goes in wrong. Avoid these mistakes and the job will look cleaner.
Do not use the wrong screw. Even if another screw seems close, it may not match the thread or length. A longer screw can hit something behind the mounting point. A shorter screw may not hold.
Do not use a power driver for final tightening. Power tools remove feel. They can strip plastic before you notice.
Do not skip alignment. If the part does not sit flat, the screw may pull it crooked. That can create gaps, rattles, or stress cracks.
Do not over-tighten. Firm is enough. Tightening past that point does not make the repair better.
Do not ignore broken plastic. A cracked mount can fail again even with the correct screw.
Do not leave other screws loose. If you removed nearby hardware, tighten it by hand during reassembly.
Quick Decision Table
Use this table before you decide the screw is the only repair needed.
| What you see | What it likely means | What you should do |
|---|---|---|
| Empty screw hole and loose part | Screw may be missing | Install screw 240578902 if fit is confirmed |
| Screw starts but spins | Mount may be stripped | Stop and inspect the mounting surface |
| Part still moves after tightening | Broken tab or second fastener issue | Check nearby clips, tabs, and screws |
| Screw will not start straight | Holes are misaligned | Re-seat the part before tightening |
| Plastic cracks near the hole | Mount is damaged | Replace or repair the affected part |
| Noise remains after repair | Another loose part may exist | Inspect surrounding panels and supports |
| Refrigerator still does not work properly | Screw may not be the root cause | Continue diagnosis beyond the fastener |
This table helps you avoid a common trap. A missing screw can be visible, but it may be only one part of the failure.
Medium Difficulty Repair Tips
A medium repair does not mean the work is hard. It means access, alignment, and judgment matter. You may need to remove parts without breaking tabs. You may also need to decide whether the mounting point can still hold.
Work slowly around plastic. Cold refrigerator plastic can be more brittle than warm plastic. If the area feels stiff, let the door stay open briefly while the unit is unplugged. Do not use heat unless a service procedure calls for it.
Keep parts in order. Place removed items from left to right as you take them out. That gives you a natural reassembly path.
Use your phone camera often. Take one photo before removal, one during access, and one before final tightening. These photos help if a bracket or cover has more than one possible position.
Check nearby parts while access is open. If you already removed a cover or shelf, inspect the surrounding screws. Tighten only loose hardware that matches the same part assembly. Do not adjust sealed system parts, electrical parts, or controls without proper diagnosis.
When a Screw Replacement May Not Be Enough
If your Frigidaire refrigerator is not working properly, a loose screw may be part of the problem. It may not be the whole problem.
A screw does not repair a failed fan motor, bad control, blocked drain, sealed system problem, worn gasket, or damaged wire. It also does not fix a broken support unless the support can still hold the screw.
Look for signs that you need more diagnosis:
- The refrigerator does not cool
- The freezer warms up
- A fan scrapes or does not run
- Water leaks inside or under the unit
- The control does not respond
- A burning smell appears
- A wire or connector looks damaged
- The same part loosens again after repair
If any of these signs appear, stop and inspect further. Do not keep tightening the screw to force the issue. Hardware should secure a good part. It should not compensate for a broken one.
How Tight Should the Screw Be?
Tighten the screw until the secured part no longer moves under light pressure. The part should sit flat. The screw head should sit cleanly against the surface.
Do not chase “extra tight.” Refrigerator liners, covers, and brackets can deform. Once plastic strips, the repair becomes more involved.
A good test is simple. Hold the part with one hand and try to move it gently. If it stays in place, stop tightening. If it moves, check alignment and nearby fasteners before adding more force.
If the screw spins without getting tighter, the hole may be stripped. Remove the screw and inspect the mount. Do not pack the hole with random material. Use the correct repair path for the damaged part.
Testing After the Repair
After you restore power, test the refrigerator in stages.
First, listen. A fixed loose panel or bracket should not rattle during door movement or normal vibration. If you hear scraping, unplug the refrigerator and inspect the area again.
Next, check fit. Open and close the door. Slide drawers in and out. Move shelves gently. Watch the area where you installed the screw.
Then, check operation. If the refrigerator was not working properly before the repair, give it time to stabilize. Cooling changes do not always happen right away. Door-open time during repair can also warm the cabinet.
Finally, inspect the screw after a short run time. Vibration can reveal poor alignment. If the screw backs out quickly, the mount may be damaged or the wrong hole may have been used.
Care Tips After Installing the Screw
A screw can loosen again if the supported part takes too much stress. You can reduce that risk with better use habits.
Do not overload door bins, shelves, or drawers near the repair area. Heavy items can flex supports and mounts. Spread weight across the refrigerator instead of loading one point.
Keep drawer tracks clean. Sticky tracks make you pull harder. That extra force can stress screws, rails, and supports.
Close doors with steady pressure. Slamming the door can shake trim, covers, and shelves over time.
During cleaning, check for loose parts. If a panel or support starts moving again, catch it early. A quick hand check can prevent a larger repair later.
