Range and Oven Model and Serial Number Guide
Identify whether the product is a freestanding range, wall oven, or cooktop, find its complete rating plate, and then select the manufacturer. Cooking appliances do not share one universal serial date code.
- 1 Choose the matching category and brand.
- 2 Enter the full serial number exactly as printed on the label.
- 3 Review the date estimate, notes, and fallback links if the serial does not decode.
The model distinguishes configuration, fuel type, and family. The serial supplies the brand-specific date positions, while verified model-era evidence may narrow a repeating year cycle.
Select the cooking-appliance brand and enter the serial number exactly as shown.
Built for fast serial/model research.Useful for appliance age estimates, replacement research, and claim documentation.Results may vary by brand, model family, and available serial data.
Installed cooking products hide labels in different places
Freestanding ranges commonly use the oven frame or storage-drawer opening. Wall ovens often place the plate on trim visible with the door open, while cooktops may require viewing the underside from the cabinet below.
Do not move a built-in or gas appliance solely to search for a rear label. Check the accessible frame, cavity, drawer, paperwork, and manufacturer instructions first.
Verified Whirlpool range example
This fixture shows the difference between a serial candidate cycle and model-assisted narrowing.
| Label Field | What It Usually Means | Why It Matters |
|---|---|---|
| Serial RX3026733 | Whirlpool year code X; production week 30 | The serial-only result is 1990 or 2020, not an automatic exact year. |
| Model WFE320M0JW0 | Recognized Whirlpool range family | The tested model-family evidence overlaps the 2020 candidate and narrows the result to week 30 of 2020. |
What the serial number can tell you
Supported cooking-product paths differ by manufacturer. Whirlpool-family strings use a length-dependent year/week layout, GE uses opening month/year letters, and LG, Frigidaire, and Samsung each use different positions.
What the model number can tell you
The model identifies range versus wall oven, fuel type, and generation. It can narrow serial candidates only when reliable family evidence overlaps one of the decoded years.
Common range and oven serial number formats
GE cooking products
~ Estimated decade.
Opening month/year letters
The first serial letters usually carry the age logic.
Whirlpool-family ranges
~ Estimated decade.
9 or 10 characters with year code + week
The year code position changes by serial length and is followed by week digits.
Frigidaire / Electrolux cooking products
~ Estimated decade.
Factory letters + year/week digits
The first numeric character after the factory letters often points to year, followed by week digits.
Samsung cooking products
~ Estimated when year codes repeat.
11-char or 15-char serial
Year and month positions change by serial length.
LG cooking products
~ Estimated decade.
Year digit + 2-digit month
The opening three serial characters usually carry the main date clue.
Range and oven serial number examples
RX3026733 + WFE320M0JW0
The serial gives week 30 and the candidate years 1990 or 2020. The tested range-family model narrows the result to 2020.
Where to find the serial number
Door and frame locations
- Behind the oven door on the frame edge
- Inside the storage drawer opening on many freestanding ranges
Built-in and wall oven spots
- Trim edge visible when the door is open
- Side frame area on some built-in installations
Fallback spots
- Rear service label on certain products
- Owner paperwork if the interior label is damaged
Common problems
- Wall ovens and freestanding ranges place the label in different spots.
- The serial result is still estimated because the year code repeats.
- A replacement door or trim panel has removed the visible tag.
- Only the model number is available from installation paperwork.
- The cooking product line spans multiple factories with different serial layouts.
FAQ
Where is the label on a freestanding range?
Inspect the oven frame with the door open and the frame exposed by removing or opening the lower storage drawer.
Where is the label on a wall oven?
Check the side or lower trim visible when the oven door is open. Avoid removing the installed appliance solely to search behind it.
Where is the label on a cooktop?
Many cooktops place it on the underside, accessible from the cabinet below. Follow the manufacturer's instructions before moving or disconnecting anything.
Can a range model number resolve a repeating serial year?
Only when reliable model-family evidence overlaps one decoded candidate. The example on this page narrows a Whirlpool cycle that way.
Why should fuel type be recorded separately?
Gas and electric versions can share styling or family names while using different service information and replacement requirements.
Does an installation date prove manufacture date?
No. Installation can occur later. Keep installation records as context while treating the supported serial result as the production evidence.
