675813⤠Whirlpool Thermal fuse Kit is â˘a thermal cutoff safety⢠component âsupplied as aâ service kit for Whirlpool laundry appliances; it⢠consists primarily of âa temperature-sensitive fuse (thermal âŁfuse)⤠and the associated âconnectors â¤and âŁmounting⤠hardware required for âŁinstallation. As a âthermal cutoff, the fuse is a nonâresettable⤠device designed to open âit’s electrical circuit when a â˘predefined temperature threshold is exceeded, â¤providing a lastâlineâ protective function against sustained overheating in an appliance’s âheating subsystem.
Inside an appliance the âthermal fuse is⣠typically⢠mounted in or adjacent to theâ heater assembly⢠or exhaust airflow path and â˘interfaces⣠functionally with the heatingâ element, âthermostats (cyclingâ and highâlimit), âthe control/relay⤠circuitry and theâ blower/ventingâ system. When the thermal fuse opens âit âinterrupts power to âŁthe heating circuit, preventing furtherâ element heating; therefore its operationâ and integrity are âdirectly⤠affectedâ by â˘heat generation, airflow and âventing performance,â and by â¤upstreamâ control signals.â Technically, selection and replacement require attention⤠to the âdevice’s⣠temperature rating, electrical continuity characteristics, mounting orientation and the thermal coupling to the surrounding duct or housing.
In this article readers will find a technical overview of âhow the 675813 thermal fuse âfunctions, guidance â¤on⤠compatibilityâ and part identification, common failure⣠symptoms to recognize (such⣠as loss ofâ heating or openâcircuit âindication), diagnostic approaches for isolating fuseârelated faults versus upstream causesand practical replacement⤠considerations â˘including matching temperature and electrical specifications, mechanical mounting and verification of underlying causes like restricted â¤airflow. The focus is on providing âtechnicians, engineers and â¤appliance⢠owners with⣠the contextual facts needed to â¤diagnose, âspecify â¤and safely replace theâ component âwhile addressing âroot causes that â¤can cause repeatâ failures.

Function â˘and âRole ofâ the Thermal fuse Assembly⤠in Whirlpool Dryer Safety Systems
Theâ 675813 Whirlpoolâ Thermal Fuse Kit provides a temperature-sensitive, âŁsingle-use interrupt in âthe dryer’s heating circuit that prevents sustained overheating and potential ignition⤠of âlint âŁor housing materials. Installed in⢠series with the heater âŁor in the exhaust path, âthe thermal âfuse opens theâ electrical circuit âwhen âthe local temperature exceeds its⤠designed threshold; onceâ opened it does not reset and must be replaced to⣠restore the circuit.The component’s role â˘is purely â¤protective rather then⢠regulatory, so correct⢠selection and installationâ require âmatching the fuse’s â˘mounting, terminal âŁtypeand temperature rating to âthe dryer⢠model and wiring harness â¤to maintain proper compatibility âand reliable operation.
- Symptom: ânoâ heatâ while drum and motor run (common⤠indicator of an open thermal⤠fuse).
- Check: verify continuityâ at room temperature with a â¤multimeter; an âopen reading indicates a blown â¤fuse.
- Cause analysis: inspect venting, lint screen, blower âwheel, âŁand cycling thermostat-vent restriction is the most frequentâ root cause⣠of repeatedâ thermal âfuse failures.
- Replacement âpractice: replace âwith the same âŁpart number or equivalent âŁspecificationâ and â¤restore proper airflow before returning â¤the⤠dryer to service.
Technicians should treat a â¤blown thermal â¤fuse as a downstream âsymptom⣠rather âthan theâ root cause; replacing⢠the 675813 Whirlpool Thermal Fuse Kit restores the âsafety âŁlink but repeated failures require correcting airflow⢠or control faults that â˘produce âsustained high temperatures. during service, isolate âthe dryer, verify⢠other heating-circuit components (heater element, âŁthermostats, high-limit sensors) and wiring for shorts⤠or poorâ connectionsand âconfirm that âthe âŁreplacement fuse is secured⣠to the â¤correct â˘mounting surface⤠and connected⤠with proper connectors to ensure âaccurate âtemperature sensing and electrical continuity under normalâ operation.

How the 675813 Whirlpoolâ Thermal Fuse Kit operates Within â˘the Dryer’sâ Thermal Management⢠Circuit
The 675813 âWhirlpool Thermal Fuse â˘Kit âserves as âŁa protective element in⣠the dryer’s⢠thermal management circuit⢠by interrupting âpower to theâ heating⣠element or heater relay âŁwhen âinternal â˘temperaturesâ exceed a âdesigned threshold. In normal⢠operation the⣠thermal âcutoff remains closed and allows current to flow to the heater; if airflowâ is restricted, the heating element orâ cabinet â˘temperature rises past the⤠fuse’s â˘trip point and the device âŁopens as a oneâtime, nonâresetting âsafeguard. Technicians will findâ the fuse mounted in or near the blower âhousing or heater assembly and wired in series with the heating circuit, soâ a blown â¤fuse willâ typically result in loss âŁof heat while âŁthe drum and motorâ continue to run.
- Common diagnostic signs: dryer tumbles but does not âŁheat, multimeter reads open continuity across the fuse, visible burn or physical damage to the⣠fuse assembly.
- Behavior inâ circuit: closed underâ normal temperature, opens⤠when threshold exceeded, requires replacement âŁratherâ than resetting.
- Compatibility considerations: match the 675813 Whirlpool â˘Thermal Fuse⢠Kit to the appliance’s part number,mounting style,and connector⢠type to ensure correct⤠thermal rating and fit.

In practice, replacing the 675813 Whirlpool Thermal Fuse kit is part⢠of addressing root causes rather than a permanent âcure: a blown thermal fuse âŁoften indicates vent blockage, âaâ failed heating⣠elementor a thermostat fault that caused excessive temperature. A practical âtroubleshooting⢠sequence isâ to⢠verify â¤continuity âacross the⢠fuse â˘with a multimeter, inspect and âŁclear the exhaust vent and lint pathwaysand then â¤confirm⣠heater âelement resistance and thermostat âoperation before installing⣠the kit. do⤠not âŁbypass or bridge the thermal cutoff; doing so defeats a safety device and creates a fire hazard.
Common failure Symptoms and Diagnostic Procedures for Thermal Fuse â˘Faults
The 675813 Whirlpool Thermal Fuse Kit âreplaces the one-time thermal â¤cutout that protects the dryer’s heating circuit from sustained overtemperature conditions. The thermal fuse is a temperature-sensitive, non-resettable device mounted âin the exhaust or heater housing; when â˘its internal element reaches the rated â¤trip temperature⤠it opens the heater circuit and prevents current from flowing âto the⣠heatingâ element. Functionally, the part⤠acts as a last-resort safety device rather than â˘aâ control component – correct part⤠selection hinges on⣠matching theâ OEM⣠part number âŁand mounting orientation âŁso the fuse â¤sees the âsame airflow and thermal⤠environment as the original installation.
Technicians â˘diagnose âŁthermal fuse faults by correlating observed⤠symptoms with measurements and an inspection of âŁthe dryer’s airflow and secondary safety devices. Disconnect power before testing,remove the fuse from its harness,and check âfor continuity âwith a multimeter: an open circuit indicates âa blown fuse. Asâ thermal fuses areâ single-use, a confirmed⤠open fuse requires âreplacement and âŁinvestigation ofâ root causes (restricted venting, failed cyclingâ thermostator⣠a shorted heating âelement) that âcan produce repeated âŁovertemperature events; doâ not bypass the fuse⢠or substitute⢠temporary jumpers. Typical âŁdiagnostic checkpoints⤠include âcontinuity â¤measurement, âvisual inspection for overheating orâ soot,⤠verification ofâ vent resistanceand testing ârelated â˘safety thermostats and the heating element for leakage to ground.
- No⤠heat while drum and motor runâ -⣠common indicator the thermal fuse has opened.
- Intermittent heating or the dryer cutting out after a short runâ -â suggests overheating â˘upstream of the fuse.
- Open continuity on the fuse âŁwhen tested with a âmultimeter (infinite resistance) – definitive â¤electrical⣠symptom.
- Visibleâ signs of overheating, â˘melted terminalsor⣠soot â¤at the fuse â˘mounting area – indicates local thermal stress.

model Compatibility, Replacement âConsiderationsand âStepâbyâStepâ Installation Guidelines for the 675813 âKit
The 675813 Whirlpool Thermal â˘Fuse Kitâ contains âŁa thermal cutoff â˘and the small mounting hardwareâ needed to replaceâ a blown⣠safety fuse in the dryer’s heating circuit. Theâ thermal cutoff is a oneâtime, normallyâclosedâ device thatâ opens when its âinternal element âŁreaches the specified temperature, interrupting current â˘to the heater to prevent fire or⣠component â¤damage. âŁCompatibility⢠depends â¤on the âŁfuse’s physical âmounting, terminal type,⣠lead lengthand ratedâ opening â¤temperature;â techniciansâ should confirm the kit’s part⤠number âagainst theâ dryer’sâ parts list or measure the original component âbefore ordering. The fuse typically mounts to the blower housing or exhaust duct â¤where it⢠monitors air temperature; mismatched spade sizes or âŁbracket geometry canâ prevent proper⢠installation even if the electrical â¤rating appears⣠correct.
Replace the âcomponent⣠only afterâ confirming the cause of overheating (blocked venting, failed thermostator restrictedâ airflow) âso the⤠new fuse is not subjectedâ to âthe âsame fault.Key replacement and verification steps â˘include:
- Disconnect power ⣠at the breaker or plug before â˘any access or âcontinuity testing.
- Access the⤠fuse (rear⤠panel or blower âhousing), documentâ wiring positions or take a photo,â then test âthe⣠removed âŁfuse withâ a multimeter for continuity â¤to confirm failure.

Q&A
What âis the 675813 âWhirlpool Thermal Fuse Kit?
The â675813 kit is⢠a replacement thermal⣠fuse assembly used on many âWhirlpool-built dryers. The âthermal fuse is a one-time safety device that opensâ (cuts electrical continuity) when the dryer overheats, protecting the âappliance âand home âŁfrom fire risk. âThe kit is intended⢠to replace a failed⤠fuse and âany⤠small mounting hardware or connectors âthat come with âthe specific kit listing.
What symptoms indicate the âthermal fuse (675813) has failed?
Common symptoms are: the âŁdryer runs but producesâ no â¤heat⤠(electric or gas), the âdryer may run but âwon’t complete a â¤cycleor in some designs the dryer âŁwon’t âstart at all â˘if the control circuit is interrupted.A blown thermal fuse typically results âin an openâ circuit, so heating⤠components will not beâ energized.
Where is â˘the â˘thermal âfuse locatedâ on a Whirlpool dryer?
Onâ most Whirlpool-style dryers âŁthe thermalâ fuseâ is mountedâ on or near the blower housing or exhaust duct, usually â¤accessible by removing the rear panel or the lower âfront service panel. Location can⤠vary by model-confirm â˘with your dryer’s model-specific parts diagram before disassembly.
How do I⣠test the 675813 âŁthermal fuse to see if âit’s blown?
Unplug the â˘dryer and access⤠the thermal fuse. Remove⤠the wire connectors. Use a⢠multimeter âset to continuityâ or⢠low ohms:⢠aâ goodâ fuse âwill show continuity (near 0 Ί); a blown fuse âŁwill âshow infinite resistance or âOLâ âon the⤠meter.â Do not test with power applied.
How doâ I âŁreplace the thermal fuse safely?
Safety â˘first: disconnect power (unplug electric dryer or shut⢠off gas and unplug). âAccess the fuse by removingâ the appropriate panel.⢠Note wiring âpositionsâ or take a photo, âremove â¤connectors and any mounting âŁclip or⢠screw, â¤and install â¤the new fuse with⢠the same⣠orientation and âsecure connections.Reinstall panels and restore â˘power.
