Seweder W10316760 Thermistor Sensor Review

Intro

If your refrigerator is icing up, running too long, or behaving erratically, the thermistor is a common and inexpensive part to check. The Seweder W10316760 (also listed as model W10316760 and cross-referenced to WP10316760/AP4538142/PS2580944/W10323459) is positioned as a compact, low-cost replacement sensor for several Whirlpool/Kenmore/Kitchenaid/Sears refrigerators. This review pulls from the product listing and real owner reports to explain what this part actually is, how it installs, what owners like and dislike, and what to verify before you buy.

What it is / first look

At its core the Seweder W10316760 is a refrigerator thermistor sensor sold as a replacement part. The listing identifies the part as model W10316760 and shows it as a single-count unit with an overall compact form factor. The item dimensions listed are 3.9" D x 3.9" W x 0.39" H and the listed color is white. The product page includes a set of replacement part numbers the part is claimed to match (for reference): WPW10323459, W10323459, 12791417, 12791417SP, 12791419SP, 1876627, AH2580944, EA2580944, PS2580944, W10280385, W10280386, W10308052, W10316760VP, W10438639, W10438761, W10452402.

Compatibility: which fridges it fits

The listing explicitly calls out compatibility with Whirlpool, Kenmore, Kitchenaid and Sears refrigerators and lists specific model numbers; for example, it states fit for KBFS22EWBL1, KBFS22EWMS1, KBFS22EWMS3, KBFS22EWMS5, KBFS22EWMS7, and KBFS22EWWH1. Buyers should treat that compatibility list as the starting point and verify the exact part number on their refrigerator before ordering.

How the listing describes the part

The listing describes the thermistor as a temperature-sensing component that sends internal-temperature information to the refrigerator's electronic control device. The stated function is to help resolve problems caused by frost buildup, overheated parts, excessively cold compartments, or extended run time. The product copy emphasizes that the part is high quality and "well-tested by the manufacturer," and it claims the part is easy to install; it also encourages unplugging the appliance and taking basic safety steps before installation.

In daily use

Thermistors themselves don’t have user-facing features — they either read temperature correctly and restore normal control behavior, or they don’t. Owner experiences recorded in the research notes point to a few repeated outcomes that matter for daily results.

What owners report works

• Several owners describe using this part to fix defrost or evaporator icing issues: "Evap icing fixed!" and "fixed my evaporator icing problem on my 4 year old Kitchenaid fridge" are representative comments. When the thermistor is the root cause, owners report the replacement restored normal cycling and halted icing.
• Other owners used the part diagnostically: replacing the thermistor confirmed the sensor was good and helped them identify a different root cause. One owner said the part "didn't fix my problem but the part worked properly and ensured that the problem was elsewhere."
• Value-for-money is a theme: multiple owners call it a "good replacement" or "good value."

What owners report doesn’t work or creates frustration

• Installation is not always plug-and-play. While the listing states it is "easy to install" and suggests watching an installation video, owner notes indicate some splicing or wiring work may be necessary. One owner described it as "Not plug and play, had to splice into existing wiring, but works fine."
• Connector reliability is a reported issue in at least one negative review: a buyer warned that the waterproof connectors (mentioned by some owners as included) were "worthless" and that the wires slipped out, causing failure after a few months. That single critical report is strong enough to merit caution when relying on the part’s connector system.
• Durability concerns appear in the negative report — that owner said the part "barely last 4 months" and advised against buying from the company. That contrasts with multiple other owners who reported long-term fixes, so longevity reports are mixed.

Materials & build quality

Concrete material details are limited in the listing. The product copy uses broad phrases like "high quality" and "well-tested by the manufacturer," but it does not list specific materials, housing composition, or connector specs. The physical size (3.9" x 3.9" x 0.39") and the white color are given in the product specs.

Owner feedback gives the clearest signal on build quality. Multiple buyers call it a "quality part" and report successful fixes across different fridge ages and brands. A handful of owners noted the part looked different from the original, yet matched the electrical characteristics (an owner remarked it had the "same ohms per degree as original").

But the negative ownership report raises a flag around connector quality and finishes: that buyer described waterproof connectors that failed and wires slipping out even after compression. Because thermistors are small and rely on secure electrical connections, a suspect connector can undermine the whole repair even if the sensor element itself is fine.

Safety considerations

Safety is front-and-center for any appliance repair involving wiring. The listing itself includes clear safety recommendations: it instructs you to unplug the appliance first, remove perishable food that could spoil during power loss, and wear work gloves to protect your hands. For the electrical connections it advises separating and insulating disconnected wires with insulating tape or using wire connectors to simplify the installation.

Owners echo the practical side of that advice. Multiple owner notes imply that installation requires hands-on wiring work rather than a simple plug-in swap. Because the listing does not claim a plug-and-play harness for every model, expect to do at least basic splicing or use connectors to adapt the new sensor to the refrigerator’s wiring harness.

Specific safety signals from owner feedback:

• Positive: several owners report successful installations that resolved defrosting and icing problems without electrical issues.
• Cautionary: at least one owner reported connector failure resulting in loss of connection after a few months. That owner described wires slipping out of the connectors and deemed the connectors "worthless." This report implies two potential safety hazards: (1) a loose electrical connection that can cause intermittent operation, and (2) the need to ensure any exposed wires are fully insulated and secured before restoring power.

Practical safety checklist derived from listing advice and owner signals:

1. Unplug the refrigerator before starting — the listing explicitly instructs this.
2. Move or remove perishable items that might be affected by the temporary power-off, as the listing suggests.
3. Use gloves, and have insulating tape or proper wire connectors on hand — the listing recommends either insulating tape or purchasing wire connectors to make installation easier.
4. Verify connector quality: if the replacement arrives with loose or flimsy connectors (owner reports vary), plan to replace or reinforce them with proper crimp connectors or solder and heat-shrink where appropriate and safe.
5. After installation, confirm secure routing and insulation of all wires before powering the fridge back on.

Who this is for / who should skip

This part is aimed at the DIY home cook or appliance hobbyist comfortable with small electrical repairs on refrigerators — especially those who can identify part numbers and confirm compatibility. The listing positions it for owners of Whirlpool, Kenmore, Kitchenaid, and Sears fridges, and includes specific model numbers (for example: KBFS22EWBL1, KBFS22EWMS1, KBFS22EWMS3, KBFS22EWMS5, KBFS22EWMS7, KBFS22EWWH1) that it claims to fit.

Who this fits well

• Owners of the exact models listed in the product description who need a direct replacement thermistor.
• People troubleshooting defrost or evaporator icing issues: multiple owners reported this part cured evaporator icing and fixed defrost-related problems when the thermistor was the fault.
• DIY-savvy users prepared to splice wires or use connectors. The listing says it is "easy to install" and points to installation videos, but owners frequently mention splicing, so basic wiring skills are helpful.

Who should skip or be cautious

• Buyers who need a certified plug-and-play harness for models not listed — the listing does not guarantee universal plug-and-play compatibility and owner notes show adaptions are common.
• Users who are uncomfortable working with refrigerator wiring. The listing recommends insulating exposed wires or using wire connectors, and the owner feedback includes at least one report of connector failure; if you’re not confident with basic wiring safety, consider professional repair or verifying the exact OEM part and harness first.
• Anyone who expects guaranteed connector reliability — one owner described early failure of the waterproof connectors, so if the integrity of the connector is critical, plan to confirm or replace them during installation.

Verdict

The Seweder W10316760 thermistor is a compact, low-cost replacement that the listing positions as a fit for a number of Whirlpool/Kenmore/Kitchenaid/Sears models. The product listing emphasizes easy installation and good build quality; in practice owner feedback splits between satisfied DIY fixes and a minority of reports of connector failure and short life.

Buy this if you have confirmed the part number on your fridge and you are comfortable doing minor wiring work or adapting connectors. Owners frequently cite that the part fixed defrost and evaporator icing issues, and several say it delivered good value. Be prepared to splice or otherwise adapt wiring on some models, and plan to inspect or reinforce the connectors during installation.

Skip or get professional help if you can’t work around a harness that doesn’t match exactly, or if you’re not comfortable ensuring a secure, insulated electrical connection yourself. The single strong negative report about connectors failing after a few months is enough reason to double-check connectors and secure them properly during installation.

Check before you buy (quick checklist)

• Confirm the OEM part number on your fridge matches one of the replacement numbers listed in the product description.
• Verify the specific fridge model appears on the listing’s compatibility list (examples given include KBFS22EWBL1 and KBFS22EWMS1, among others).
• Plan for basic wiring: have insulating tape, proper wire connectors, crimp tools, or heat-shrink available because installation may require splicing.
• Inspect the included connectors on receipt; if they look flimsy, be prepared to replace or reinforce them to avoid loose connections.
• Unplug the appliance and remove perishable contents as recommended in the listing before starting work.
