How to Install Bearing WP8546455 in a Whirlpool Room Air Conditioner
When your Whirlpool room air conditioner is not working properly, a worn bearing can be one possible cause. The bearing helps a moving part stay supported while it turns. When that support wears down, the unit may run rough, sound strained, or fail to move air the way it should. How to Install Bearing WP8546455 is a repair you can plan at home if you work with care and verify your model first.
This guide focuses on Whirlpool bearing WP8546455 for the supplied room air conditioner models. You will learn how to prepare, remove the old bearing, install the replacement, and test the unit before normal use.
Before you start, confirm the full model number on your unit. The supplied compatible models are 110.20702990, 110.20722990, 110.23812100, 110.24642300, and 110.26912691. If your model tag does not match your records, stop and check the owner information first. Whirlpool provides owner resources through its Owner Manuals page.
Before You Start
A bearing repair needs patience more than force. You need to reach the part, remove nearby panels or supports, and keep track of every fastener. The job is listed as medium difficulty because access can take time.
Plan for 30 to 60 minutes. Add more time if the unit has dust buildup, stuck screws, or tight panel fit. Do not rush the first disassembly. Most mistakes happen when you pull a panel before finding all clips or screws.
Work on a stable surface with good light. If the room air conditioner sits in a window, remove it only if you can do that safely. Many units are heavy and awkward. Get help if the unit feels hard to control.
Use your phone to take photos at each step. A quick photo can save you from guessing during reassembly. Shoot the panel layout, wire routing, screw locations, and bearing area before removal.
Also check the general repair path before you buy parts. A bad sound or poor operation does not always mean the bearing failed. Dirt, loose mounting parts, blocked airflow, or a damaged fan part can cause similar symptoms.
Fit Check for Bearing WP8546455
Do not install any part until you confirm fit. The part number for this repair is WP8546455. The supplied compatible model list includes:
| Supplied model number | Brand | Appliance type | Part type |
|---|---|---|---|
| 110.20702990 | Whirlpool | Room air conditioner | Bearing |
| 110.20722990 | Whirlpool | Room air conditioner | Bearing |
| 110.23812100 | Whirlpool | Room air conditioner | Bearing |
| 110.24642300 | Whirlpool | Room air conditioner | Bearing |
| 110.26912691 | Whirlpool | Room air conditioner | Bearing |
Find the model tag on your unit before you open the cabinet. Room air conditioner tags may be placed where you can see them after removing the front grille or filter cover. Some tags sit on the side, frame, or inside edge.
Read the full model number, not just the first few digits. One changed digit can point to a different build. If the number is worn or hard to read, use a flashlight and take a close photo.
If the model number does not match one of the supplied numbers, do not assume this bearing fits. Use the model tag and OEM number together when you search for parts.
Whirlpool also maintains a Product Help Library for general support. Use it to review basic owner information before deeper repair work.
Tools and Supplies You May Need
Your exact tool list can vary by cabinet style. Since no model-specific tool list was supplied, use a basic repair setup:
- Phillips screwdriver
- Flat blade screwdriver
- Nut driver set
- Work gloves
- Flashlight or work light
- Small container for screws
- Camera or phone
- Soft brush or vacuum
- Clean cloth
- Replacement bearing WP8546455
Choose hand tools before power tools. A power driver can strip small screws or crack plastic trim. If you use one, set it to low torque.
Keep screws grouped by panel. Many room air conditioner screws look alike, but length can matter. A long screw in the wrong spot may damage plastic, foam, or metal.
Use a soft cloth under parts you remove. This keeps trim from getting scratched. It also keeps small pieces from rolling off the table.
Do not use oil, grease, adhesive, or sealant unless the service information calls for it. Extra lubricant can attract dust or reach areas where it does not belong.
Safety First
Unplug the room air conditioner before you touch any internal part. Do not rely on the power button. The cord must be out of the outlet.
Give the unit time to sit after unplugging it. Avoid touching electrical terminals, control parts, or capacitor areas. If you are not comfortable around electrical parts, stop and call a qualified technician.
Wear gloves when handling the cabinet. Sheet metal edges can be sharp. Move slowly around coils, fins, and fan parts.
Do not bend refrigerant tubing. Do not cut, open, heat, or puncture any sealed system part. The bearing repair should not require opening the sealed refrigeration system.
Keep the unit level while you work. Do not set it on the control side unless the service information allows it. Water, dirt, or loose parts can shift inside the cabinet.
If you smell burning, see melted wiring, or find damaged insulation, stop. A bearing replacement will not fix an electrical hazard.
How to Install Bearing WP8546455 Safely
Common Mistakes That Make This Repair Harder
The biggest mistake is skipping the model check. A part can look close and still fit wrong. Always use the full model number and OEM part number.
Another mistake is forcing the cabinet. Room air conditioner panels often have hidden hooks or clips. If a panel does not move, it is still held somewhere.
Some people also lose screw order. That slows reassembly and can cause damage. Use cups, labels, or cardboard to track fasteners.
Do not clean with heavy liquid near electrical parts. A dry brush and vacuum are safer for most dust removal. If you need deeper cleaning, follow the owner information.
Avoid bending fan parts while reaching the bearing. Even a small bend can cause vibration. Keep your hands and tools clear of the fan path.
Do not ignore a damaged bracket. A new bearing cannot stay aligned if the mount is bent. Fix the support issue first.
Repair Decision Matrix
Use this table before you decide whether to continue. It helps you avoid replacing a bearing when another issue is more likely.
| What you notice | What it may mean | Best next move |
|---|---|---|
| Unit runs rough and bearing area has visible wear | Bearing may be worn | Replace WP8546455 after fit check |
| Poor airflow with a dirty filter | Airflow restriction | Clean filter and retest first |
| Scraping after cabinet reassembly | Panel or fan contact | Unplug, realign cabinet, inspect fan path |
| Fan feels loose at the support point | Bearing or support wear | Inspect bearing and bracket together |
| Burning smell or melted wire | Electrical hazard | Stop and call a qualified technician |
| New bearing does not match old part | Wrong part or wrong model | Stop and verify model and part number |
| Noise remains after bearing replacement | Related part may be worn | Inspect fan, bracket, and mounting points |
This matrix does not replace the service information. It gives you a safer order of checks. Start with low-risk causes before deeper part replacement.
How to Tell the Repair Worked
A good repair should improve the symptom that led you here. The room air conditioner should run smoother than before. It should not scrape or shake more than it did before the repair.
Watch the first few minutes closely. Listen near the front and side of the cabinet. A loose panel can sound like a bad bearing, so check the cabinet too.
Feel for vibration on the outer case. Some vibration is normal, but harsh shaking is not. If the unit shakes, unplug it and inspect the fan path.
Check airflow at the outlet. The air should move without a strained sound. If airflow stays weak, clean the filter and inspect for blockage.
Let the unit cycle under normal use only after the short test passes. Stay nearby during the first longer run.
When to Stop and Get Help
Stop if you see damaged wiring. Do not tape up burned, brittle, or melted wires and keep going. That repair needs proper diagnosis.
Stop if the unit trips a breaker or outlet protection device. A bearing repair should not be used to work around electrical trouble.
Stop if you need to move sealed refrigerant tubing for access. Do not bend or open sealed system parts.
Stop if the fan assembly looks damaged. A broken or warped fan can cause the same complaint. It may also damage the new bearing.
Stop if the cabinet will not close correctly. A misaligned cabinet can create noise, poor airflow, or unsafe contact.
You can also use Whirlpool’s Service & Support resources when you need brand support documents or owner help.
Maintenance After Bearing Replacement
Good airflow helps the bearing and fan area work with less stress. Keep the filter clean during heavy use. Check it more often during hot weather or dusty conditions.
Vacuum the front grille when dust builds up. Do not push dirt deeper into the unit. Use a soft brush for the intake area.
Keep curtains, furniture, and blinds away from airflow paths. Blocked air makes the unit run harder. It can also make normal sounds seem louder.
Listen for new sounds early. A small scrape can become a bigger repair if ignored. Unplug the unit before any inspection.
Do not spray water into the control area. Keep electrical areas dry. Follow owner instructions for cleaning parts that collect dust or moisture.
Check the cabinet screws after the first few uses. A screw that was not seated well may loosen. Tighten by hand if needed.
