675813 whirlpool Thermal Fuse Kit is a replacement thermal cutoff assembly intended to protect heating circuits from sustained overtemperature conditions. The kit consists of a temperature-sensitive, one-time thermal fuse (thermal cutoff) supplied with the appropriate connector or wiring harness for direct installation; it is a passive, non-resettable safety device designed to open the circuit when its rated temperature threshold is exceeded.
Inside an appliance the thermal fuse sits in series with the heating element or its control circuit and interacts directly with the heating system, airflow path and temperature-sensing components such as thermostats and high-limit switches. By interrupting current when the local temperature surpasses its rating, the fuse prevents excessive heat buildup that could damage internal components or present a fire hazard. It is most commonly found in electric clothes dryers and other home heating appliances where concentrated heat and restricted airflow can create risk; correct placement and thermal coupling to the airflow or heater housing are critical to its intended function.
In this article readers will find a technical overview of the fuse’s function and design characteristics, guidance on compatibility and how to verify the correct temperature/current ratings for a given appliance model, common failure symptoms (for example, a dryer that runs but does not heat), troubleshooting steps to isolate the thermal fuse versus related components (thermostats, heating element, venting/airflow), and practical replacement considerations such as matching part specifications, proper connector use, mounting orientation and safety precautions. The focus is on delivering the technical context needed for reliable diagnosis and correct replacement rather than on procedural step-by-step installation instructions.

Function and thermal-safety role of the dryer thermal fuse assembly
The 675813 Whirlpool Thermal Fuse Kit is a thermal cutout assembly intended to interrupt the dryer’s heater circuit when internal temperatures exceed a specified safety threshold.in normal operation the fuse remains a closed circuit, allowing the heating element to receive power; if the measured temperature at the fuse location rises above its rating, the device opens and permanently disconnects the heater to prevent insulation ignition or other overheating damage. The thermal fuse in this kit is a single-use, non-resettable component, so loss of continuity indicates the part must be replaced rather than reconditioned, and any replacement must match the original temperature and electrical ratings and terminal style to maintain design safety margins.
- Primary function: open the heater circuit at overtemperature to prevent fire or component damage.
- Common symptoms of a failed fuse: blower runs but no heat, dryer stops heating intermittently, or a fully dead heater circuit while other systems remain powered.
- Typical failure causes: restricted venting/airflow, lint buildup around the heating assembly, or a secondary thermostat/heater fault that drives excessive temperature.
- Diagnostic note: verify continuity with a multimeter and confirm adequate airflow and correct thermostat operation before declaring the fuse the sole cause.
Compatibility and practical installation require matching mechanical fit and electrical/thermal specifications; the kit is supplied to replace OEM Whirlpool thermal-fuse assemblies that use the same mounting and terminal style, but installers should confirm the part number and ratings against the dryer’s service manual.After replacing a blown 675813 Whirlpool Thermal Fuse kit, technicians should correct the underlying cause-clean the exhaust duct, clear lint from the housing, inspect the heating element for shorted coils, and test thermostats-as repeated fuse failures indicate a systemic thermal problem rather than a single-component fault. Always disconnect power before servicing, use the specified replacement with identical temperature/current ratings, and verify proper airflow and heater cycling on a test run following installation.

How the 675813 Whirlpool Thermal Fuse Kit interfaces with heating, thermostat and airflow systems
The 675813 Whirlpool Thermal Fuse Kit is a non-resettable thermal safety device supplied as a replacement for dryers that use a fuse in the heater circuit. Installed in series with the heating element, the thermal fuse opens its circuit when internal cabinet temperature exceeds its design threshold or when sustained over-temperature conditions occur due to restricted airflow or a failed blower. In practical terms, an open fuse removes power to the heating element independently of the control thermostat or timer, so a dryer may continue to tumble but produce no heat; field technicians typically verify the fuse for continuity as a primary diagnostic step when heat is absent.
- Circuit role: wired in series with the heater so opening the fuse interrupts heater current.
- Behaviour: single-use, non-resettable – once opened the fuse must be replaced.
- Thermostat interaction: thermostats cycle the heater during normal operation, while the thermal fuse serves as a secondary safety cutoff.
- Airflow impact: clogged vents or a failed blower raise internal temperatures and can cause fuse activation.
the thermal fuse interfaces with both control and airflow systems without providing control feedback: it does not modulate temperature but simply removes power when a hazardous condition is reached. When replacing the 675813 Whirlpool Thermal Fuse Kit, match mounting, connector style, and circuit placement to the appliance model as the fuse’s physical location (frequently enough near the heating element or exhaust duct) determines how it senses temperature. For troubleshooting, technicians should inspect venting and blower operation first; if airflow is restored and the fuse is open, replace the fuse and then confirm that thermostats and high-limit cutouts are functioning to prevent repeat failures.
| Item | Description |
|---|---|
| Electrical role | Series safety cutoff for the heating element; prevents current flow when opened. |
| Actuation behavior | Designed to open at a predefined over-temperature; non-resettable and requires replacement after activation. |
| Service note | Replace with an equivalent kit that matches terminals and mounting; verify airflow and thermostat functions to avoid recurrence. |
Common failure symptoms and diagnostic measurements indicative of thermal fuse faults
The 675813 Whirlpool Thermal Fuse kit supplies a replacement thermal cutoff that functions as a one-time, temperature-activated safety device in the dryer heater/exhaust circuit. The thermal fuse is a non-resetting link designed to open when a sustained over-temperature event occurs, interrupting the heater circuit (and on some models a control or motor circuit). In practice, lint accumulation, blocked vents, or a failed cycling thermostat produce the sustained heat that will blow the fuse; replacing it without correcting the underlying airflow or control fault will usually result in a repeated failure. verify model compatibility and the fuse mounting location before installation to ensure the kit matches the appliance wiring and terminal layout.
- No heat while motor runs – heater circuit open (common symptom of a blown thermal fuse).
- Intermittent or no power to controls – some models use the fuse in the control feed and will not start if open.
- Multimeter continuity reads open/infinite resistance – definitive indicator of a blown fuse.
- Low-resistance continuity (≈0-2 Ω) when cold and intact – indicates a good fuse.
| Item | description |
|---|---|
| Continuity test | With power removed, measure across the fuse: a healthy fuse shows low ohms (~0-2 Ω) or beeps on continuity; a blown fuse is open/infinite. |
| Voltage check | With appliance powered and load expected, measure supply voltage to the fuse: absence of expected voltage can indicate upstream open thermostats or wiring faults. |
Disconnect power before removing or testing the thermal fuse. For diagnosis, start with a continuity check at the fuse terminals; if open, confirm and then investigate airflow restrictions and cycling/limit thermostats upstream of the fuse. If continuity is present but the dryer still lacks heat,measure live voltage to the heater circuit and inspect heater elements and associated thermostats/relays. Documenting measured resistances and voltages against known-good values for the specific model helps distinguish a genuine fuse failure from an unrelated control or wiring fault.
Compatibility,replacement considerations,installation procedure and post-replacement troubleshooting
The 675813 Whirlpool Thermal Fuse Kit replaces the thermal cutoff used to protect dryer heating circuits from sustained over-temperature conditions. The thermal fuse in the kit is a one-time, normally-closed device that opens when its temperature threshold is exceeded; it does not reset and must be replaced if it reads open with a multimeter. When selecting this kit for a repair, match the temperature rating, spade-terminal size, wire gauge, and mounting footprint to the original part and verify the OEM cross-reference or service manual for your specific model. Mechanical fit and proper insulation of the leads are as critically important as electrical specifications as poor mounting or incorrect clearances can change the local thermal surroundings and lead to premature failure.
Installation follows standard appliance-safety and diagnostic practice: disconnect power,gain access to the thermal fuse location (typically near the blower housing or heating element assembly),confirm the old fuse is open with a continuity check,then install the replacement ensuring correct orientation,secure mounting,and strain-relief on the wiring. After reassembly, verify the repair by running a heat cycle while checking exhaust airflow and heater circuit continuity; a repeated open fuse usually indicates restricted venting, a failing heating element, or a faulty cycling thermostat rather than a bad fuse alone. common post-replacement checks include verifying adequate exhaust temperature rise, confirming the heater draws the expected current, and ensuring thermostats and high-limit switches operate within their specified ranges.
- Symptoms to verify before and after replacement: dryer runs but produces no heat, fuse reads open on continuity check, and repeated fuse failures coincide with restricted venting or heater faults.
- Diagnostic steps: continuity check on fuse and heater element, inspect venting for obstructions, measure line voltage at the element during a heating cycle.

Q&A
What is the 675813 Whirlpool Thermal Fuse Kit and what does it do?
The 675813 thermal fuse kit is a replaceable safety device used on many Whirlpool-family dryers. The thermal fuse is a one-time thermal cutoff that opens the electrical circuit if the dryer overheats, preventing fires. The kit typically contains the fuse and necessary mounting hardware or connectors to install it in the dryer’s heating/airflow assembly.
What symptoms indicate the thermal fuse (675813) has failed?
Common symptoms of a blown thermal fuse include: the dryer runs but produces no heat, the dryer won’t start at all, or the dryer may stop partway through a cycle.Exact symptoms vary by model because the fuse can be wired in the heating circuit, the motor circuit, or both. Always test the fuse before replacing if you’re not sure.
Where is the thermal fuse located in the dryer?
On most Whirlpool-family dryers the thermal fuse is mounted on or near the blower housing or the heating element assembly. It is indeed usually accessible by removing the back panel, lower front panel, or lint filter housing depending on the model. Consult your model’s wiring diagram or service manual to find the exact location before disassembly.
How do I test the 675813 thermal fuse?
Always unplug the dryer (and shut off the gas if it’s a gas dryer) before testing. remove the fuse from the dryer and use a multimeter set to continuity or the lowest ohms range. A good fuse will show near-zero ohms or continuity; an open (infinite resistance) reading means the fuse is blown and must be replaced. Do not test the fuse in-circuit with power applied.
How do I replace the 675813 thermal fuse safely?
Unplug the dryer (and turn off the gas for gas models). Access the fuse per your model’s service instructions,carefully disconnect the wire connectors,remove the old fuse and mount the new 675813 in the same orientation. Reconnect the wires, reassemble panels, and restore power/gas. Do not bypass the fuse – it’s a required safety device. After replacement, verify dryer operation and check for the root cause of overheating before regular use.
What typically causes the thermal fuse to blow and how can I prevent it?
The most common cause is restricted airflow (a clogged vent, lint trap, or blocked exterior vent) leading to overheating. Other causes include a stuck or failed cycling thermostat, a shorted heating element, or blower/motor problems. To prevent future failures, clean the lint screen and dryer vent regularly, inspect and clean the exhaust duct, and verify other heating-system components are functioning correctly.
Can I bypass the thermal fuse to get the dryer working?
No. Bypassing the thermal fuse is unsafe, illegal in many jurisdictions, and can create a serious fire hazard. The thermal fuse is a required safety device. If the fuse is blown, replace it with the correct part (675813 or exact OEM equivalent) and fix the underlying cause of overheating.
How do I confirm compatibility and what should I look for when buying part 675813?
Confirm compatibility by checking your dryer model number against the part listing from Whirlpool or an authorized parts dealer. ensure the kit includes the correct style of fuse and connectors for your model. Buy OEM or high-quality aftermarket parts, verify the seller’s return policy and warranty, and consult the dryer’s parts diagram if you’re unsure. if in doubt, provide your exact model number to the parts supplier or technician.
