This Part Fixes These Problems

No Power / Dead Control Panel

Dishwasher shows zero response — no lights, no beeps, nothing happens when buttons are pressed. The blown thermal fuse cuts all power to the control board.

Won't Start

Indicator lights illuminate normally but pressing the Start button has no effect. The fuse has opened the circuit preventing any cycle from initiating.

Stopped Mid-Cycle

Dishwasher halted during a wash or rinse cycle and will not restart. Standing water may remain in the tub. A tripped thermal fuse is the most common cause.

Blinking Clean Light

The Clean light blinks repeatedly on the door panel and no cycle can be started. This is a common symptom of a blown bi-metal fuse on Whirlpool-platform dishwashers.

Overheating / Repeated Fuse Failure

Fuse blows repeatedly after replacement. Root cause is typically high amp draw from a failing heating element, faulty motor, or poor wire connections creating excess heat at the terminals.

Product Description

Why Choose Our W10258275 Dishwasher Bi-Metal Thermal Fuse Kit?

🔧
Built to OEM SpecificationsRated at exactly 86°C / 187°F trip point — matches factory spec for Whirlpool, KitchenAid, Maytag, and Kenmore dishwashers. Fuse dimensions: 5/8"L × 5/8"W × 1-1/4"H.
⚡
Complete Kit — No Extra Parts NeededIncludes (1) Thermal Cutoff (TCO), (1) pre-wired harness assembly (4-7/8"L), (2) zip ties (6-3/4"L), and printed installation instructions. Everything in the box to complete the repair correctly the first time.
🔒
Factory-Terminated Wire HarnessThe included harness with factory-installed terminals eliminates the high-resistance connection that causes premature fuse failure when reusing the original wiring. Splice in the new harness exactly as Whirlpool engineered it.
🏷️
Wide Cross-Reference CoverageDirect drop-in replacement for AP4423189, PS2360984, AH2360984, EA2360984, W10136048, W10258275VP, W10344801, 1549751, and 661663. Covers hundreds of Whirlpool-platform dishwasher models across multiple brands.
🛡️
Metal/Plastic ConstructionDurable metal and plastic body resists heat and vibration inside the door control panel. The thermal cutoff protects the dishwasher circuit from overload and cuts current to the heating unit when temperatures exceed the rated threshold.
⏱️
10-Minute DIY RepairAccessible through the front door panel — no need to pull the dishwasher from the cabinet. Most homeowners complete this repair in under 15 minutes with a screwdriver and wire stripper.

💡 Pro Tip: How to Know If Your Thermal Fuse Has Blown

Your part is likely the culprit if you notice any of the following:

⚠️ Dishwasher has completely no power — control panel is totally dark and unresponsive

⚠️ Clean light on the door panel blinks repeatedly but the machine will not start a cycle

⚠️ Indicator lights (Normal, Heated Dry, Steam) glow but pressing Start does nothing

⚠️ Dishwasher stopped mid-cycle and now has zero response to any button

Test the fuse with a multimeter set to continuity mode. A good fuse shows continuity (closed circuit). An open reading confirms the fuse has blown. Always investigate the root cause — faulty heater element (check for 10–30 Ω), loose harness connections, or overloaded motor windings — before installing the new fuse to prevent repeat failures.

Questions & Answers

How do I know if the W10258275 thermal fuse is blown and needs replacement?
Answered by Support Team  ·  Mar 15, 2024
Set a multimeter to continuity mode and probe both terminals of the fuse. A healthy fuse shows continuity (the meter beeps or reads near 0 Ω). If the meter reads open (OL / no beep), the fuse has blown and must be replaced. Also look for a completely dead control panel or a Clean light that blinks but the dishwasher won't start — these are the most common symptoms of a failed bi-metal fuse.
Why does my thermal fuse keep blowing after replacement?
Answered by Support Team  ·  Nov 20, 2023
Repeat fuse failure means an underlying component is drawing excessive current or generating excessive heat. Check the heating element for proper resistance (10–30 Ω at room temperature), inspect the main circulation motor windings, and examine every wire connection on the harness for loose or flared terminals. Loose terminals create resistance that generates heat directly at the fuse location. Always install the complete kit with the new harness — reusing old terminals is the most common reason the fuse blows again quickly.
Why does the replacement kit require splicing in a new harness instead of just swapping the fuse?
Answered by Support Team  ·  Jan 8, 2025
Whirlpool redesigned the replacement procedure after discovering that the original wire harness terminals could develop high electrical resistance over time due to terminal wear or slight looseness. This elevated resistance generates heat right at the fuse mounting point, causing the new fuse to trip prematurely — even though nothing else is wrong. The factory-installed terminals on the new harness provide a clean, low-resistance connection. You must cut the old wires and splice in the included harness for a lasting repair.
Will this part fit my KitchenAid or Maytag dishwasher, or is it only for Whirlpool?
Answered by Support Team  ·  Jul 22, 2024
Yes — the W10258275 thermal fuse kit fits dishwashers across the entire Whirlpool Corporation platform, including Whirlpool, KitchenAid, Maytag, Kenmore, Amana, Jenn-Air, Crosley, Estate, Roper, and Inglis branded models. Hundreds of model numbers are compatible. Please verify your specific model number against our compatibility list or contact us before ordering if you are unsure.
Is this an easy repair for a homeowner with no appliance repair experience?
Answered by Support Team  ·  Feb 10, 2026
Yes — this is one of the most beginner-friendly dishwasher repairs available. The thermal fuse is accessed by opening the door and removing the inner door panel screws — the dishwasher does not need to be pulled from the cabinet. You will need a Phillips screwdriver, wire stripper, and a multimeter. The included instructions walk you through each step, and the average repair time is 10–15 minutes. Always disconnect power before starting.

We typically respond within 1 business day. Include your appliance model number for the fastest answer.
