675813 Whirlpool Thermal Fuse Kit is a thermal cutoff assembly designed to interrupt the heater circuit of an appliance when a predefined temperature limit is exceeded. As a temperature-actuated protective device, the kit typically contains a one-time thermal fuse (a normally closed device that opens on overtemperature), associated leads or connector pigtails, and mounting hardware appropriate for factory installation locations.
Inside an appliance, this thermal fuse sits in the appliance’s heating and airflow path and provides a last line of defense against sustained overtemperature conditions. It directly interfaces with the heating element circuit and the appliance control system, and it is typically installed in clothes dryer heating assemblies or comparable laundry appliance housings near the exhaust or heater housing. when the measured local temperature rises beyond the fuse’s rated trip point, the device opens the circuit to stop current flow to the heater, isolating the heating element from the control electronics and preventing further temperature rise or potential component damage.
In this article readers will find a technical overview of the 675813 thermal fuse kit covering its functional principle, typical application locations, and compatibility considerations (temperature rating, electrical rating, and connector/mechanical fit). The piece also outlines common failure symptoms-such as loss of heat, intermittent heating, or visible fuse damage-and gives a diagnostic framework that includes visual inspection, continuity checks with a multimeter, and assessment of related systems (heating element, thermostats, venting and airflow). the article discusses practical replacement considerations: confirming the correct OEM/part number and ratings, ensuring proper mounting and connector integrity, and following safe electrical isolation practices during service.

function and Role of the Thermal Fuse in Dryer Overheat Protection
The 675813 Whirlpool Thermal Fuse Kit contains a factory-specified thermal cutoff used to protect the dryer from sustained overtemperature events. The thermal fuse is a temperature-sensitive, single-use device mounted in the dryer’s exhaust or blower housing and wired in series with the heating circuit (and in some designs the motor control). When the local air temperature at the fuse location exceeds the manufacturer’s cutoff threshold-due to a failed thermostat, shorted heating element, or restricted exhaust airflow-the fusible element melts and opens the circuit to remove power from the heater, preventing further temperature rise and reducing fire risk.
Because the thermal fuse is single-use (non-resettable), it must be replaced with a component that matches the original electrical and thermal ratings; the fuse does not degrade gradually but changes state abruptly when its activation temperature is reached. Technicians commonly confirm a blown fuse with a continuity check using a multimeter and should always evaluate root causes of overheating (blocked vent, clogged lint screen, failed cycling thermostat, or partial heater short) before installing a replacement. Typical field symptoms and verification steps include the items below.
- Symptoms: no heat while drum turns, dryer stops mid-cycle, or unit fails to power the heating circuits.
- Verification: continuity check across the fuse; inspect venting and lint traps for obstructions; measure heater and thermostat continuity.
- Replacement guidance: use the exact replacement rating and mounting style to ensure correct operation and safety.

How the 675813 Whirlpool Thermal Fuse Kit Works Inside the Appliance: Integration with Thermostats and Wiring
The 675813 Whirlpool Thermal Fuse Kit is a one-time thermal safety device installed in the dryer’s heat path and wired in series with the heater circuit and motor cutoff systems. In normal operation the fuse is a normally-closed link that provides continuity at ambient temperatures but opens irreversibly when the temperature at its mounting location exceeds its design limit,removing power from the heating element and often disabling the motor through series wiring. It is indeed used alongside thermostats – for exmaple the cycling thermostat that controls normal operating temperature and a high-limit thermostat that provides a secondary automatic cutout - with the thermal fuse acting as a final non-resettable safety to prevent sustained overheating from blocked vents, failed thermostats, or other airflow failures. Technicians should match the kit to the appliance model and verify connector types and mounting to ensure correct physical and electrical integration.
Electrically the fuse is typically installed in series with the heating element feed or the heater relay path so an open fuse eliminates current flow through the heater; because of series wiring an open thermal fuse will produce the same symptom as a failed heating circuit (no heat) even when the thermostat and element test good. Troubleshooting commonly uses continuity checks at room temperature and temperature simulation tests for thermostats: if the fuse is open, replace it and correct the underlying cause (restricted venting, lint buildup, or failed thermostatic control) before returning the appliance to service. Practical diagnostic steps include visual inspection of the mounting location for charring or lint, verifying continuity across the fuse with the dryer unplugged, and confirming that other temperature controls in the same circuit (cycling or high-limit thermostats) operate within their rated setpoints.
- Common diagnostic steps: inspect venting, test continuity on the fuse, test thermostats, replace fuse if open and verify connectors.

Diagnostic Indicators and Common Failure Symptoms of a Faulty Thermal Fuse Kit
The 675813 Whirlpool Thermal Fuse Kit is a single-use temperature cutoff designed to protect the dryer’s thermal circuit by opening when a predefined over-temperature condition occurs.In operation the fuse is wired in series with the heating element circuit (and on some models with the motor circuit), and it is indeed not resettable; once the internal fusible link melts the circuit remains open until the component is replaced. Technicians should confirm the kit’s terminal style, harness length, and specified trip temperature against the appliance service sheet because physical fit and temperature rating determine compatibility and safe operation across different Whirlpool models.
Common failures manifest as loss of heat, intermittent heating, or complete shutdown of the dryer depending on the circuit the fuse protects. Typical diagnostic indicators include an open circuit on a cold continuity test, visible thermal damage, or repeated trips caused by ventilation blockage or failed thermostats; replacing the fuse without addressing root causes (clogged venting, failed cycling thermostat, or shorted element) will frequently enough result in recurrence. Use a multimeter to check continuity-an open reading implies the fuse has operated-and inspect the vent path and heating element for shorts or hotspots before confirming replacement. practical examples: a dryer that runs but produces no heat usually indicates the fuse or high-limit thermostat in the heating circuit is open, whereas a dryer that will not run at all can have the fuse placed in the motor feed circuit and thus disable the motor when blown.
- Dryer runs but no heat – open fuse or related high-limit thermostat in the heating circuit.
- Dryer does not start – fuse might potentially be in series with motor circuit on some models.
- Intermittent heating or frequent trips – likely overheating source such as clogged venting or failing cycling thermostat.
- Visible charring or melted terminals – replace the fuse and investigate thermal damage sources.
| Item | Description |
|---|---|
| Continuity | Cold reading near 0 Ω = intact; open/OL = blown (replace with same rating) |
| Location | usually mounted on blower housing or near the heating element; verify against model diagram |
| Compatibility | Match trip temperature,terminal type,and harness connectors; 675813 Whirlpool Thermal Fuse Kit is specified for select Whirlpool models |
Replacement Considerations,model Compatibility,and Installation Procedure for Whirlpool Dryers
The 675813 Whirlpool Thermal Fuse Kit contains a non-resettable thermal fuse and the necessary wiring/harness to restore the dryer’s overtemperature protection. The thermal fuse is a single‑use safety element wired in series with the heating or control circuit; when internal air or component temperature exceeds the manufacturer-specified trip point, the fuse opens and removes power to the heating element (and in some designs to control circuitry), stopping additional heat input. A blown fuse is a diagnostic indicator of sustained overheating caused by restricted exhaust airflow, a failed cycling thermostat, or a shorted heating element – not a random electrical hiccup – so technicians should evaluate those root causes before or during replacement.
When replacing the part, confirm model compatibility by checking Whirlpool service literature or the dryer’s model and serial numbers; the kit may include a specific harness length and connector style required for certain cabinet layouts. For safe installation: disconnect all power, verify the new fuse has the correct temperature rating and connector configuration, remove the access panel to reach the blower housing or high‑limit location, and replace the component without splicing if the harness matches.After installation, verify continuity across the fuse before reassembly, clear any vent obstructions and measure airflow or run a heating cycle to confirm normal thermal behavior. Do not bypass the fuse or substitute a device with a different trip characteristic - that defeats the intended safety function.
- Practical replacement checklist: disconnect power, document connector orientation, test old fuse for open circuit, install new fuse/harness, restore venting, and perform functional test cycle.

Q&A
What is the 675813 Whirlpool Thermal Fuse Kit and what does it include?
The 675813 kit is a genuine Whirlpool replacement thermal fuse assembly designed for certain Whirlpool/Kenmore dryers. The kit typically contains the thermal fuse itself and the necessary mounting hardware or wiring adaptors required for installation on compatible models. Always verify the kit contents against the product listing and your dryer model before starting repairs.
What symptoms indicate the 675813 thermal fuse has blown?
Common symptoms are: the dryer runs but does not produce heat, the dryer fails to start or the control panel is unresponsive on some models, and occasionally the dryer will shut down mid-cycle. A blown thermal fuse is most often associated with loss of heating, but behavior can vary by model depending on how the fuse is wired into the circuit.
Were is the thermal fuse located on a Whirlpool dryer?
On most Whirlpool dryers the thermal fuse is mounted on or near the blower housing or exhaust duct, downstream of the heating element. Exact location varies by model, so check your dryer’s diagram (usually on the dryer cabinet or in the service manual) before disassembly.
How can I test the 675813 thermal fuse to see if it’s blown?
Cut power to the dryer (unplug or switch off the breaker). Disconnect the fuse’s wiring and use a multimeter set to continuity or ohms. Place the probes on the two terminals: a good fuse will show continuity (near zero ohms); a blown fuse will show open circuit (OL or infinite resistance). Do not test live circuits-always disconnect power first.
Is the 675813 thermal fuse resettable, or can it be reused?
The thermal fuse is a one-time safety device and is not resettable.If it has blown, it must be replaced. Reinstalling a blown fuse or bypassing it is unsafe and can create a fire hazard and void warranties.
What typically causes the 675813 thermal fuse to blow and how can I prevent it?
Thermal fuses blow because the dryer overheats. Common causes include clogged or restricted venting, lint buildup around the heating element or blower, a failed heating element shorting to the housing, or faulty thermostats. Preventive measures: clean the lint screen and vent system regularly,clear the exhaust duct to the outside,inspect/clean the dryer interior periodically,and repair faulty components promptly.
Can I install the 675813 kit myself, or should I hire a technician?
If you are pleasant with basic appliance repair and electrical safety (disconnecting power, identifying wires, and using hand tools), you can replace the fuse yourself by following the service instructions for your model. If you are unsure, uncomfortable working on gas/electric appliances, or the dryer has additional failures (heating element, thermostats, vent problems), hire a qualified technician.
After replacing the 675813 thermal fuse the dryer still won’t heat – what should I check next?
Do not just replace the fuse again without finding the cause. check the exhaust vent for blockage, inspect the heating element for continuity and shorts to the housing, test cycling thermostats and the high-limit thermostat, and verify the blower motor and door switch operation. Addressing the underlying fault that caused overheating is necessary to prevent the new fuse from blowing.
