A Kenmore model number decoder is the single most useful tool for understanding your appliance, because Kenmore itself has never manufactured anything — Sears, and now Transformco, contracted outside manufacturers to build appliances that were then rebadged with the Kenmore name. The good news is that the first three digits of any Kenmore model number reliably identify which real manufacturer actually built your unit, and once you know that, you know exactly what design, parts, and common failure points to expect.
Why “Kenmore” Alone Never Tells the Full Story
Search for repair help using only the word “Kenmore” and you will get a mix of advice written for entirely different underlying appliances, since a Kenmore refrigerator, dryer, or range hood could be any of six different manufacturers depending on the exact unit. That mismatch is the single biggest reason generic troubleshooting steps found online sometimes do not match what you are actually seeing on your appliance.
Finding the Model Tag
The model number is printed on a manufacturer’s tag or sticker, usually located inside the appliance door frame, on the inner cabinet wall, on the back panel, or on the underside of a cooktop or range hood, depending on appliance type. Look for a string of digits, often preceded by “Model” or “Model No.,” typically several digits long and sometimes broken into two groups.
Reading the First Three Digits
Once you have the full number, the first three digits are what matter for identifying the OEM. Based on verified prefix assignments: 106, 110, 198, 664, 665, and 850 are Whirlpool-built; 795 and 796 are LG-built; 253, 336, 417, 587, 622, 628, 719, 790, 791, and 970 are Frigidaire/Electrolux-built; 362, 363, and 464 are GE-built; 233 is Broan-built (used on range hoods); and 174, 335, and 596 are Amana-built, with Amana being Whirlpool-owned and generally following Whirlpool design patterns.
Why the Prefix Matters
Knowing the true OEM behind your Kenmore appliance changes how you troubleshoot it. A dryer showing an F1/F01 code is Whirlpool-built (110 prefix) and needs a different diagnostic approach than one showing a d90 or d95 vent code, which is LG-built (796 prefix) — see our guide on Kenmore dryer not heating for exactly how those two diverge. The same logic applies to parts sourcing: a genuine OEM replacement part for a 110-prefix dryer comes from the Whirlpool parts ecosystem, not from LG or Frigidaire catalogs, which our parts lookup guide walks through step by step.
A Real Example
Take a Kenmore Elite SmartHeat dryer with model number 110.097872601 — the 110 prefix confirms this is a Whirlpool-built unit, which tells you immediately to expect Whirlpool-style control-board error codes rather than LG-style vent-monitoring codes, even though both are sold under the same Kenmore Elite name.
What If the Tag Is Missing or Worn?
On older appliances, the model tag can fade, get painted over during a remodel, or fall off entirely after years of heat and cleaning. If the tag is illegible, check the original owner’s manual if it survived, or look for a duplicate serial plate that some appliance types include in a second location, such as behind a kickplate or inside a storage drawer. As a last resort, our technicians can often identify the OEM platform from the physical design of internal components during a service visit, even without a readable tag.
Before You Troubleshoot
Before calling about any repair, take thirty seconds to find your model tag and check the prefix against the table above — it saves time on the phone and helps our team arrive with the right genuine OEM part already in hand. For the full brand backstory behind why this decoding is even necessary, see our guide on who actually makes Kenmore appliances, and see how the tiers compare in our Kenmore vs. Elite vs. Pro guide.
Once you know your model’s true OEM builder, schedule a repair with confidence that our experienced independent technicians will bring the correct genuine OEM parts, backed by a 30-day labor warranty.
