Where to find model number on GE side by side refrigerator?
On a GE side-by-side refrigerator like model GSM20IEMDWW, the model number is printed on a rating label inside the fresh food (refrigerator) compartment, most often on a side wall near the top or on the ceiling area just inside the door.
Common places to check first
Look for a white or silver sticker that lists model and serial.
- Inside the refrigerator compartment on the upper left wall
- Inside the refrigerator compartment on the ceiling/top liner
- On a side wall behind the top shelf area
- Along the door frame (hinge side) when the door is open
- Behind the crisper drawers area (less common)
Quick tips to spot the label
- Use a flashlight; the print can be small.
- Wipe condensation or smudges off the label with a dry cloth.
- Don’t confuse the model tag with the water filter label or shelf part markings.
What the label usually includes
| Item on label | What it’s used for |
|---|---|
| Model number (example: GSM20IEMDWW) | Matching the correct parts list and diagrams |
| Serial number | Identifying production run details |
| Electrical ratings | Verifying power requirements for service |
Why it matters
Using the exact model number helps us match the right GE refrigerator parts for your unit, such as a control component or cooling-system part, without guesswork.
If you’re ordering a temperature-related part after confirming the model, a common example is the refrigerator temperature sensor WR55X10025.

What is the most common problem with a GE refrigerator?
The most common GE refrigerator complaint is not cooling properly (fresh food warm, freezer not holding temperature). On your GE GSM20IEMDWW side-by-side, the usual causes are airflow problems, a defrost issue, or a failed temperature-sensing/control part.
Most common symptoms and what they usually point to
- Freezer cold but refrigerator warm: evaporator fan not moving air, iced-over evaporator, or a defrost control problem
- Both sections warm: compressor start issue, condenser airflow problem, or sealed-system trouble
- Temperature swings: sensor or control board problems
- Water leaking: defrost drain restriction or water supply/valve issue
- Ice maker or dispenser not working: inlet valve, ice maker, or dispenser mechanism issue
Quick checks we recommend first (no parts needed)
- Confirm the controls are set to normal cooling (not “off” or “demo”).
- Make sure vents inside both compartments are not blocked by food.
- Clean dust from the condenser area and verify the condenser fan is running.
- Check door gaskets for gaps; warm air leaks can mimic a cooling failure.
- Listen for the evaporator fan in the freezer; it should run when the compressor runs.
Common parts that fix “not cooling” on this model
| Symptom | Likely area | Part on this page |
|---|---|---|
| Warm fresh food, freezer OK | Temperature sensing/control | Refrigerator temperature sensor WR55X10025 |
| Frost buildup, warm temps | Defrost system | Refrigerator thermostat WR50X10068 |
| Temps unstable or incorrect | Electronic control | Refrigerator temperature control board WR55X10150 |
| No water to ice maker/dispenser | Water supply control | Refrigerator water inlet valve assembly WR57X33326 |
| Lights out when door opens | Door switch or bulb | Refrigerator light bulb 40A15 |
Why it matters
A refrigerator that is not cooling can spoil food quickly and can also overwork the compressor. Catching airflow, defrost, or sensor issues early often prevents bigger, more expensive failures.

How do I find the right GE part number?
For your GE GSM20IEMDWW side-by-side refrigerator, the right part number starts with the exact model number. Use GSM20IEMDWW to match the correct parts diagram, then confirm the part by name and ID before ordering (for example, a sensor, valve, or control board).
Step-by-step: match the correct part
- Find the model tag and confirm it reads GSM20IEMDWW (letter and number mix matters).
- Identify the system you’re repairing: cooling, defrost, ice maker, dispenser, or lighting.
- Use the parts list/diagram for GSM20IEMDWW to locate the part by location and description.
- Cross-check the listing details: part name, part ID, and where it installs.
- If multiple similar parts appear, match by function and placement (fresh food vs. freezer section).
Common GE refrigerator part identifiers you’ll see
GE listings often show both a part ID (the catalog identifier used on the parts page) and a manufacturer part number. Either can help, but the safest match is model number plus diagram location.
| What you see | What it means | How to use it |
|---|---|---|
| Part name | What the part does | Match to your symptom and location |
| Part ID (example: WR55X10025) | The identifier on the parts page | Use it to confirm you’re ordering the exact listing |
| Part number (example: WR50X10027) | Manufacturer number | Useful for cross-referencing and verifying compatibility |
Examples of model-matched parts on this page
If your symptoms line up, these are examples of parts already listed for GE GSM20IEMDWW:
- Temperature sensing and control: refrigerator temperature sensor WR55X10025, refrigerator temperature control board WR55X10150
- Water and ice supply: refrigerator water inlet valve assembly WR57X33326, refrigerator ice maker WR30X10093
- Defrost and cooling airflow: refrigerator thermostat WR50X10068, refrigerator evaporator fan motor WR60X10074
Why it matters
GE refrigerators use many similar-looking switches, sensors, and motors across different series. Matching by model number + diagram position prevents ordering a part that fits physically but connects differently or controls the wrong zone.

How can I tell if a GE part is compatible?
For your GE GSM20IEMDWW side-by-side refrigerator, the most reliable way to confirm part compatibility is to match the part to your exact model number (GSM20IEMDWW) and then verify the part ID and description in the parts list for that model.
Quick compatibility checklist (works for any GE refrigerator part)
- Confirm the model number on the appliance data tag matches GSM20IEMDWW exactly.
- Compare the part ID (not just the part name) to the part listing for your model.
- Check for similar-looking parts with different IDs; small design changes can matter.
- If you are replacing an electrical part, match the connector style and wire count before ordering.
- If you are replacing a water system part, match the inlet and outlet connection type and orientation.
Examples of model-matched parts on this page
These are parts already listed for GE GSM20IEMDWW; using the exact part ID helps avoid ordering the wrong item.
| What you are fixing | Part to match by ID | What it affects |
|---|---|---|
| Temperature readings, warming issues | Refrigerator temperature sensor WR55X10025 | Temperature sensing and control logic |
| No water to dispenser or ice maker | Refrigerator water inlet valve assembly WR57X33326 | Water flow into the refrigerator |
| Defrost problems, frost buildup | Refrigerator thermostat WR50X10068 | Defrost temperature monitoring |
| Light not working | Refrigerator light bulb 40A15 | Interior lighting |
Why it matters
“Close enough” parts often do not fit correctly or do not plug in the same way. Matching by model number and part ID protects cooling performance, prevents leaks, and reduces repeat repairs.
Safety notes before you start
- Unplug the refrigerator before accessing wiring, fans, or control components.
- Shut off the water supply before servicing any water line or valve.
- Wear work gloves; sheet metal edges inside the cabinet can be sharp.
