Where can I find a Kenmore fridge model?
You can find the model number for your Kenmore refrigerator on the rating label inside the fresh food (refrigerator) compartment; on many side-by-side units like model 3639554720, it’s commonly on an interior wall near the crisper area or on a label you can see after removing the lower crisper drawer. Confirm the exact label location in the 3639554720 owner's manual.
- Inside the refrigerator compartment on a side wall near the crisper drawers
- Behind or just above the lower crisper drawer (remove the drawer to see the label)
- Along the door frame (hinge side) when the door is open
- Behind the base grille or near the kickplate area (lower front)
- On the back exterior panel near the power cord entry
Record these exactly as shown on the label:

Where is the model number on a Kenmore side by side refrigerator?
On Kenmore side-by-side refrigerators like model 3639554720, the model number is printed on the appliance identification label inside the fresh food (refrigerator) compartment. We recommend using the label that lists both the model and serial information so you can match parts and service instructions correctly in the 3639554720 owner's manual.
Look for a paper or foil label in these typical locations:
- Inside the refrigerator section on a side wall (often near the top)
- On the ceiling of the fresh food compartment near the light
- Behind or near the crisper drawers (check the side wall just above them)
- Along the door frame area (hinge side) when the refrigerator door is open
Use this simple process to locate the label without removing major parts:
- Open the refrigerator door and scan the upper side walls first
- Move items off the top shelf so you can see the liner clearly
- Pull the crisper drawers out far enough to look at the side walls behind them
- Use a flashlight; labels can be low-contrast or partially covered by shelves
Record both numbers exactly as shown; they are used for different things.
| What to record | What it’s used for | Example format |
|---|---|---|
| Model number | Matching the correct parts diagrams and part numbers | 3639554720 |
| Serial number | Identifying production details for service and compatibility | Letters plus numbers |
Kenmore model numbers can look similar across different refrigerator designs. Using the exact model number from the ID label helps us match the correct door parts, ice maker components, and electrical items (such as a light bulb or door switch) for your specific 3639554720 refrigerator.
If you are ordering parts, we recommend searching by model number first on the parts list for this model, or using Sears PartsDirect to search by model number when you are shopping across multiple appliances.

How can I tell how many cubic feet my Kenmore refrigerator is?
For your Kenmore 3639554720 side-by-side refrigerator, the most reliable way to confirm cubic feet is to check the model and capacity information on the refrigerator’s rating plate inside the cabinet. This model family is commonly listed as “Side by Side 20-27 models” in the documentation, so capacity typically falls in that range; the rating plate gives the exact number for your unit.
- Look for the rating plate inside the fresh food section (commonly on a side wall).
- Check behind or near the crisper drawers (some units place the label lower in the cabinet).
- Look for wording such as “Total volume”, “Capacity”, or “Cu. Ft.”.
- Use the model identification details in the 3639554720 owner's manual to confirm label location and model family.
If the label is missing or unreadable, we use an internal-volume estimate.
- Measure the usable interior of the refrigerator section (height, width, depth in inches). Do the same for the freezer section.
- Multiply each section:
H x W x Dto get cubic inches. - Add both sections together.
- Convert to cubic feet by dividing by 1,728.
| What you measure | Units | What it tells you |
|---|---|---|
| Interior height x width x depth | inches | Cubic inches per compartment |
| Total cubic inches ÷ 1,728 | cubic feet | Approximate total capacity |
Knowing cubic feet helps us match the right refrigerator parts and accessories (like shelves, bins, and ice and water dispenser components) and it also helps when comparing storage space across Kenmore side-by-side models.
When you are ready to repair or maintain your refrigerator, we recommend ordering by model number to ensure fit. Common dispenser and ice-related parts shown for this model include the refrigerator water valve WR57X10051 and refrigerator door switch WR23X427. You can also search by model number on Sears PartsDirect.

What causes a side-by-side refrigerator to stop cooling?
A Kenmore 3639554720 side-by-side refrigerator usually stops cooling because power is interrupted, the temperature control is set incorrectly (including OFF), airflow is blocked, or the unit is in a normal defrost period where the compressor can pause for about 30 minutes. See the owner's manual for model-specific checks.
- Confirm the refrigerator is plugged in and the outlet has power (test the outlet with a lamp).
- Check the temperature control; make sure it is not set to OFF.
- Make sure doors are fully closing and not being held open by food packages.
- Look for blocked air vents inside the fresh food and freezer compartments.
- Avoid loading a lot of warm food at once; it can temporarily raise temperatures.
| What you notice | Likely cause | What to do next |
|---|---|---|
| No lights, no fan, no compressor sound | No power to the refrigerator | Verify outlet power, breaker/fuse, and plug connection |
| Lights on but cooling stops briefly | Normal defrost cycle | Wait up to 30 minutes and recheck temperatures |
| Freezer cold, fresh food warm | Airflow problem (blocked vents, fan issue) | Clear vents; listen for fan airflow |
| Both sections warm, runs a lot | Dirty condenser area or frequent door openings | Clean condenser area; reduce door openings |
If troubleshooting points to a specific failure, these model-compatible parts are commonly related:
- Refrigerator defrost thermostat WR50X122 (defrost system issues can lead to poor cooling over time)
- Refrigerator defrost control WR9X489 (defrost timing/control problems)
- Fan motor WR60X187 (if airflow is weak and temperatures rise)
When cooling stops, food safety and compressor run time are the biggest concerns. Simple issues like a control set to OFF, blocked vents, or a normal defrost pause are fast fixes; catching them early helps prevent longer warm-ups and unnecessary part replacement.
If you need to order a replacement part for your Kenmore 3639554720, use the parts list for this model or search by model number on Sears PartsDirect.

What are the most common problems with Kenmore refrigerators?
The most common problems we see on Kenmore refrigerators like model 3639554720 are poor cooling, water leaks, ice maker or dispenser issues, and unusual noises. These usually trace back to airflow problems (dirty condenser coils or a failed fan motor), defrost system trouble, or a water supply/valve issue; our 3639554720 owner's manual covers several quick checks.
- Not cooling or warm temperatures: dirty condenser coils, failed condenser/evaporator fan, or a defrost problem causing frost buildup
- Water under the refrigerator: clogged defrost drain, loose water line, or a leaking inlet valve
- Ice maker not making ice: freezer too warm, water supply off, or ice maker shutoff arm stuck in the STOP (up) position
- Ice or water dispenser not working right: frozen chute, broken lever, or dispenser door not sealing
- Rattling or vibration: refrigerator not level, items vibrating on shelves, or a rattling ice maker supply line
Start with these fast, high-impact steps before replacing parts:
- Pull the base grille and vacuum dust from the condenser area; the manual recommends cleaning condenser coils at least once a year.
- Confirm the temperature controls are set correctly (not OFF).
- If the unit seems “dead,” check the outlet and breaker, then verify the power cord is fully seated.
- For ice maker issues, confirm the water supply is on and the freezer is cold enough for ice production.
- If you hear rattling, move the refrigerator about 1/2 inch away from the wall to reduce supply-line vibration.
If troubleshooting points to a failed component, these are common fixes for this model family:
| Symptom | Common part to check/replace | Example from this model’s parts list |
|---|---|---|
| No ice or weak water flow | Water inlet valve | Refrigerator water valve WR57X10051 |
| Frost buildup, warm fridge | Defrost thermostat/control | Refrigerator defrost thermostat WR50X122, refrigerator defrost control WR9X489 |
| Warm temps, noisy rear | Condenser fan motor | Fan motor WR60X187 |
| Dispenser won’t actuate | Dispenser lever | Refrigerator dispenser lever WR17X3089 |
For ordering, we recommend using the parts list for model 3639554720, or searching by model number on Sears PartsDirect.
Cooling, ice making, and leak issues often start small (dust buildup, airflow restriction, a weak valve) but can lead to spoiled food, recurring ice jams, or water damage. Quick maintenance and targeted part replacement restores normal temperatures and reliable ice and water.
