675813 Whirlpool Thermal Fuse Kit is a thermal cutoff assembly designed as a non‑resettable safety device that opens the electrical circuit to a heater when exposed to temperatures above its rated threshold. As a temperature‑sensitive component,the kit typically contains the fuse element and the necessary mounting hardware and leads for integration into a heating circuit.
Inside an appliance, the thermal fuse serves as a last‑resort overtemperature protector for the heating system; it is commonly mounted on or near the heater housing, blower housing, or exhaust path of residential dryers and other household heating appliances. The fuse interacts with the heating element,thermostats/temperature sensors,the control board,and the ventilation system by interrupting power if excessive heat is detected,thereby preventing thermal damage,component failure,or fire risk. Proper placement and reliable thermal coupling to the monitored surface are essential for the device to function as intended.
In this article you will learn how the 675813 thermal fuse functions, how to verify compatibility with specific appliance models and electrical ratings, common failure symptoms to watch for (such as loss of heat or an open circuit on continuity testing), basic troubleshooting steps to isolate the fuse from related thermostat, heating element, and venting issues, and practical replacement considerations including correct part selection, mounting orientation, wiring integrity, and measures to prevent repeat failures. The focus is on technical diagnostics and safe, code‑aware replacement practices rather than promotional details.

function and Role of the Thermal Fuse in Whirlpool Dryer Safety Systems
The 675813 whirlpool Thermal Fuse kit supplies a single-use, temperature-sensitive protective device that interrupts the dryer’s heating circuit when temperatures exceed the component’s rated threshold. The thermal fuse is wired in series with the heater or control circuit so that excessive heat-caused by blocked exhaust ducts, lint accumulation, a failed thermostat, or a shorted heating element-opens the fuse and permanently breaks the circuit to prevent fire or damage. The fuse does not reset; a blown unit requires replacement with the correct part number or an equivalent component with the same temperature and electrical ratings to restore safe operation.
- Common symptoms: dryer runs but produces no heat; in some models a blown fuse prevents any control or heater operation, resulting in no-start conditions.
- Diagnostic actions: verify exhaust airflow and clear lint, inspect the heater and thermostats for faults, and confirm continuity across the fuse with a cold multimeter before replacement.
- Replacement considerations: match temperature rating and connector type, mount in the original location, and address root causes (venting or element faults) to avoid repeated failures.
From a practical service perspective, technicians should treat the thermal fuse as a final safety device rather than a cure for recurring symptoms: replacing the part without correcting obstructed vents or a malfunctioning heater often leads to immediate repeat failure. Electrical testing is straightforward-measure continuity across the fuse when cold; an open reading indicates a blown fuse-but full troubleshooting should also include heater resistance and thermostat checks,plus airflow measurement. When fitting a replacement,follow the appliance wiring diagram and use proper spade connectors or OEM-style attachments to preserve circuit integrity and heat dissipation characteristics.

How the 675813 Whirlpool Thermal Fuse Kit Works Inside the Dryer’s Exhaust and Control Circuits
The 675813 Whirlpool Thermal Fuse Kit provides a thermal cutoff element intended to interrupt the dryer’s heating circuit when temperatures exceed a safe threshold. Installed in the exhaust or blower housing, this thermal fuse is a series safety device that monitors air temperature and airflow; under normal conditions it is closed and allows the heater to energize. In many Whirlpool designs the fuse is a single‑use (typically non‑resettable) thermal cutoff: if sustained over‑temperature conditions occur-frequently enough caused by blocked venting or failed thermostats-the fuse opens and permanently interrupts the circuit to prevent overheating. Technicians should confirm fit, connector style, and mounting orientation against the dryer model when selecting the 675813 Whirlpool Thermal fuse Kit to ensure electrical and mechanical compatibility.
Electrically the fuse sits in series with the heater relay or control board inputs so that an open fuse removes power to the heating element; in some control configurations it also prevents the control from advancing heating cycles until the fault is corrected. Common service symptoms include no heat while the drum still tumbles, or intermittent heating tied to airflow restrictions; measuring continuity across the fuse with the dryer powered off is the standard diagnostic. Replace the fuse only after addressing root causes such as clogged ducts or a failed high‑limit thermostat, since the thermal fuse typically indicates an upstream airflow or temperature control failure rather than a standalone wear item.
- Symptoms: no heat with motor running, intermittent heat, or dryer shutting down on temperature rise.
- operation: normally closed safety cutoff that opens under sustained over‑temperature.
- Service tip: verify vents and thermostats before replacing the fuse; confirm continuity with a multimeter when cool.
| Item | Description |
|---|---|
| Function | interrupts the heater/control circuit on sustained over‑temperature to prevent fire risk. |
| Typical location | Mounted in the exhaust path or blower housing where it senses outgoing air temperature. |
| Testing | With power removed, check for continuity; an open reading when cool indicates the fuse has tripped and needs replacement. |
Common Failure Symptoms and Predictive Indicators of a Faulty Thermal Fuse Kit
The 675813 Whirlpool Thermal Fuse kit contains a one-time thermal cutoff designed to interrupt the dryer’s heater circuit when internal temperatures exceed the designed safety threshold. Functionally, the thermal fuse is a non-resettable temperature-sensitive conductor: under normal operation it provides a low-resistance path, but it will permanently open if exposed to sustained overtemperature conditions. When selecting or fitting this kit, confirm the electrical rating, lead length, and mounting orientation match the original component so the fuse responds within the intended thermal profile and does not introduce additional thermal stress or poor connections that can affect compatibility and performance.
- No heat at all despite the motor and blower running.
- Intermittent heating or the dryer heats for a short period then stops.
- Visible discoloration, melting, or charring at the fuse or connector block.
- Repeated thermal fuse failures after resolving unrelated heating or venting faults.
- Dryer cycles do not complete or will not advance when temperature rises.
Diagnostics focus on verifying the thermal fuse’s state and the system conditions that caused it to open: a multimeter continuity check that shows open (no continuity) indicates the fuse has actuated and must be replaced. Equally important is determining whether the opening was caused by an isolated heater fault or by chronic conditions such as restricted venting, a failing cycling thermostat, or a shorted heating element; these upstream faults will cause repeated fuse replacements if not corrected. Technicians typically combine a visual inspection, continuity check, and temperature monitoring (for example using an IR thermometer at the air outlet and heater housing) to confirm both the fuse failure and the predictive indicators that point to the root cause.
| Item | Description |
|---|---|
| Normal state | Low resistance path; allows current to heater during normal cycles |
| failure indicator | Open circuit on continuity test, or visible heat damage at the fuse or terminals |
Compatibility Matrix: supported Whirlpool Dryer Models and Part Cross‑References for the 675813 Kit
The 675813 Whirlpool Thermal Fuse Kit supplies a temperature‑sensitive, one‑time thermal cutoff designed to interrupt the dryer’s heater circuit when sustained overtemperature is detected. In typical installations the thermal fuse is mounted on the blower housing or heater housing and wired in series with the heating element; when the fuse opens it produces an open circuit that prevents the heater (and in some configurations the motor) from receiving power. technicians verify a blown fuse with a continuity check using a multimeter; as this is a non‑resettable protective device, a failed fuse requires replacement rather than repair. The kit is intended to match the electrical rating, mounting footprint, and connector style of the OEM part so the replacement restores the original protective function without altering the control logic of the dryer.
Compatibility is determined by three practical factors: the fuse’s temperature and current rating, the physical mounting and lead/connector configuration, and the dryer model’s parts cross‑reference in the manufacturer service documentation. For example, two dryers may look identical externally but use different fuse mounting tabs or fast‑disconnect terminals that require the harness pieces included in a kit; conversely, a fuse with the correct rating but different mounting may fit only with additional adapters. to confirm compatibility, inspect the dryer’s model tag for the exact assembly number, compare the original fuse’s electrical markings, and consult the service parts list; if a model uses multiple thermal cutouts or a thermostat stack rather than a single cutoff, the 675813 kit may not be the correct replacement and the specific assembly called out in the parts list should be ordered rather.
- Quick checks: measure continuity, compare electrical rating on the old part, and verify connector/mount orientation before installing.
| Item | Description |
|---|---|
| Fuse function | One‑time thermal cutoff that opens the heater circuit when local temperature exceeds its rated threshold. |
| Compatibility checks | Match temperature/current rating, mounting tab and connector type, and cross‑reference the dryer model/service manual. |
| Failure indication | No heat with a complete power supply to the dryer; multimeter shows open circuit across the fuse. |
Replacement Considerations, Required Tools and Step‑by‑Step Installation for the 675813 Thermal Fuse Kit
The 675813 whirlpool Thermal Fuse Kit contains a one‑shot thermal cutoff designed to open the heater circuit when airflow or temperature protection limits are exceeded. The device is a temperature‑sensitive link mounted in the dryer’s exhaust/air path or heater enclosure; it interrupts power to the heating element or control circuit rather than acting as a thermostat.Technicians can verify failure with a continuity check (cold fuse should show low resistance) and confirm compatibility by matching the kit part number and mounting style to the dryer’s model plate. Typical service symptoms that implicate the thermal fuse include a dryer that tumbles but produces no heat or a unit that stops heating after intermittent operation; these symptoms should prompt checking vents,thermostats,and the heating element in addition to the thermal fuse itself.
For replacement,disconnect electrical power and inspect the venting and temperature sensors to address root causes before installing the 675813 whirlpool Thermal Fuse Kit; repeated fuse failures commonly indicate restricted airflow or a failed thermostat rather than a defective fuse alone.Replace the fuse with an exact part that matches the original thermal rating and mounting arrangement, secure all spade connectors and insulation, and perform a live test cycle while monitoring temperature and airflow. Use appropriate personal protective equipment,retain original mounting hardware or use the kit’s hardware,and follow continuity and functional checks after reassembly to ensure the heating circuit is restored and that safety devices operate correctly.
- Required tools: multimeter, 1/4″ and 5/16″ nut drivers, needle‑nose pliers, insulated screwdrivers, work gloves.
- Key replacement steps: cut power, remove access panel, locate fuse on blower housing/heater box, document wiring, disconnect spade terminals, replace fuse with kit, restore wiring and panels, verify continuity and run test cycle.
- Practical checks: inspect lint build‑up and vent restrictions, test high‑limit thermostat and heating element for shorts before assuming fuse failure caused the issue.

Troubleshooting and Diagnostics: Continuity Testing, Temperature Profiling and Root‑Cause Analysis
The 675813 Whirlpool Thermal Fuse Kit contains one or more non‑resettable thermal cutouts designed to interrupt power to the heating circuit when case or exhaust temperatures exceed safe limits. For a technician, the first diagnostic step is a continuity check: isolate power, disconnect the kit from the wiring harness, and measure resistance across the fuse terminals with a digital multimeter set to ohms or continuity.A functioning thermal fuse will read as a short or very low resistance; a blown fuse will show an open circuit or infinite resistance. Inspect the mechanical fit, terminal type, and mounting orientation as part of compatibility verification, since poor contact or incorrect connector adapters can produce false open readings even when the element in the kit is intact.
Temperature profiling and root‑cause analysis determine why the thermal fuse operated rather than simply replacing it. Use a K‑type thermocouple or contact thermistor to record inlet, drum, and exhaust temperatures through a full heat cycle and note any sustained elevated zones or rapid spikes that precede a fuse blow. common root causes include restricted venting and lint buildup that produce a gradual,sustained rise in exhaust temperature,a failing cycling thermostat that permits continuous heating,or shorted heating elements that locally overheat the housing.After replacing the thermal fuse, correct the underlying fault and validate the repair by repeating the continuity check and confirming the thermal profile returns to normal operating ranges.
- Quick diagnostic checks: continuity at room temperature, visual inspection of terminals/harness, and thermocouple spot checks at exhaust and inlet.
- Symptoms suggesting thermal-fuse operation: no heat with motor running, intermittent heating, or dryer that runs briefly then stops heating.
- post-replacement verification: restore correct airflow, measure temperature profile during a full cycle, and confirm stable thermostat behavior.
| Item | description |
|---|---|
| Continuity Test | Unplug unit, disconnect fuse, ohmmeter should show near 0 Ω for good fuse; open circuit indicates failure. |
| Temperature profiling | Use thermocouple to log inlet and exhaust temps; look for sustained high exhaust or abrupt local spikes. |
| Common Causes | Restricted venting, lint blockage, failed thermostat, or heating-element faults that cause overheating. |
Q&A
What is the 675813 Whirlpool Thermal Fuse Kit and what does it do?
The 675813 thermal fuse kit is an OEM safety device used on many Whirlpool-family dryers.It contains a thermal fuse (and mounting hardware) that opens (cuts power) if the dryer overheats, preventing fires by disabling the heating circuit or entire dryer when a specified temperature limit is exceeded.
What symptoms indicate the 675813 thermal fuse has failed?
common symptoms of a blown thermal fuse include: the dryer runs but produces no heat (electric dryers), the dryer stops mid-cycle or won’t start even though the drum motor runs, or the dryer won’t start at all. A blown fuse typically results from overheating caused by restricted venting, a faulty thermostat, or a failed heating element.
where is the thermal fuse located on a Whirlpool dryer?
On most Whirlpool/Maytag/Kenmore dryers the thermal fuse is mounted on or near the blower housing or exhaust duct, typically accessible by removing the dryer’s rear panel or front access panel depending on the model. Check your dryer’s model-specific parts diagram to find the exact location.
How do I test the 675813 thermal fuse to see if it’s blown?
First disconnect power to the dryer. Remove the fuse and disconnect its wires. Use a multimeter set to continuity or ohms: a good fuse will show continuity (~0 ohms). A blown fuse will show open circuit (no continuity). Only test when the fuse is cool; if it shows no continuity it has failed and should be replaced.
Can I replace the thermal fuse myself and what tools are needed?
Yes, most competent DIYers can replace it. Safety first: unplug the dryer (or turn off breaker/gas). Tools commonly needed include a screwdriver or nut driver, pliers, and possibly a multimeter for testing. Remove the appropriate access panel, unplug the fuse leads, remove mounting hardware, install the new kit, reconnect leads, and reassemble. Follow the model-specific service instructions.
What else should I check if the thermal fuse keeps blowing repeatedly?
If the new thermal fuse blows again, do not just replace it repeatedly. Inspect and correct the root cause: clean lint from the dryer cabinet, lint trap, and entire vent system; check and repair a restricted or crushed vent hose; test the cycling and high-limit thermostats, and test the heating element for shorts. Persistent overheating is usually caused by airflow restriction or a faulty temperature-control component.
Is the 675813 a one-time-use part and is it interchangeable with other part numbers?
Yes, thermal fuses are one-time safety devices - once blown they must be replaced. 675813 is an OEM Whirlpool part used in many Whirlpool-family dryer models; compatibility varies by model. Always verify compatibility using your dryer’s model number and the manufacturer’s parts list or a reputable parts lookup before buying.
How much does the 675813 thermal fuse kit typically cost and does it come with a warranty?
The thermal fuse kit is generally inexpensive compared with other dryer repairs; retail prices are commonly low (often under $30 depending on supplier). Many sellers offer short limited warranties on replacement parts – check the vendor’s warranty and return policy. If the dryer is under manufacturer warranty, check for authorized service options first.
