675813 Whirlpoolâ Thermal fuse â¤Kit is a temperature-sensitiveâ safety device supplied as a replacement kit for â˘Whirlpool heating appliances. It comprises âone or⢠more thermal cutoffs (thermal fuses) and associated terminals or mounting hardware designed âŁto interrupt âelectrical flow⤠when a preset temperature⣠threshold is exceeded. As a protective, single-use component in an appliance’s⤠thermal management⤠system, theâ kit âŁis a simpleâ electromechanical â¤element rather than an electronic control module.
Inside an â¤appliance, the thermal fuse serves as âŁaâ last-resort over-temperature protectorâ that opens the heating âcircuit when abnormalâ temperatures occur. it⢠directly interacts with the heating⤠element âŁor burner circuitâ and is⢠monitored indirectly by the control âboard and other thermostatic sensors;â when the fuse opens it prevents current âfrom â¤reaching⣠the⤠heater,stoppingâ further temperature rise. As it is âŁindeed triggered⢠by⣠excessive heat, â˘its operation is closely linked to the appliance’s airflow, âheating element â˘condition, thermostatâ settingsand cabinet ventilation paths.
This article willâ explain the 675813⤠kit’s functional principles, typicalâ installation locationsand compatibility considerations for âtechnicians and owners. It will describeâ common failureâ symptoms (suchâ as⢠loss of⢠heat âor a machine that runs but does not heat),step-by-step troubleshooting methods including⢠continuity testing and⣠airflow âinspections,and practical replacementâ considerations such as âcorrect⤠temperature rating,connectorâ types,mountingâ orientation,and necessaryâ safety precautions. The⢠goal is âto provide theâ technicalâ context needed to diagnose aâ thermal-fuse-related⣠fault and to select and install the â˘correct replacement part without operational or safety compromises.

Function and Role of the Thermal âŁFuseâ Assembly âŁin Dryer Overheat Protection
The 675813 Whirlpool Thermal Fuse Kit âcontainsâ a⣠thermal fuse⤠assembly that serves as a â˘non-resettable overtemperature cutoff in⢠the dryer’s safety âchain.Theâ thermalâ fuse is⣠typically mounted in the exhaust or on theâ heater âhousing âand is wired in series with the heating âŁcircuit; âwhenâ sustained⤠temperaturesâ exceed⤠the device’s rated tripâ point the fuse opens âto interruptâ power⣠to the heater â¤(and on some machines to the entire control circuit), preventing continuedâ heatingâ that could leadâ to â˘component damage or ignition. Unlike cycling âthermostats âor âhigh-limit thermostats that modulate or repeatedly â˘open and close under normal âconditions, this thermal fuseâ is designed âŁto open once⢠at a defined temperature and remain open⣠until replaced, so aâ blown fuse requires installation of âa new assembly such as the 675813 kit âwith matching terminal and â¤temperature âspecifications.
Technically, the thermal fuse responds to a âsustained overtemperature condition rather thanâ transient spikes; failures commonly indicate an underlying airflowâ or â¤heaterâ fault rather thanâ a defective fuse alone. Technicians verify functionality with âŁa continuity check⤠across⣠the fuse contacts – closed âat⣠room temperature and open ⤠when blownâ – and should inspect venting, lint traps, blower operationand â¤the â˘cycling thermostat or⣠heating element for shorts â¤when⣠a fuse âŁhas âoperated. Common, reproducible symptoms â¤and â¤troubleshooting cues include:
- No âheat whileâ the drum tumbles (open fuse or⤠heater element failure).
<li Dryer runs briefly then loses heat (intermittentâ overheating or a thermostat causing repeated âtrips).
<liExcessive âŁdryer âcabinet or exhaust temperaturesâ measured withâ a probe â(indicates⢠airflow restriction âor a failed heater control).

howâ the 675813 Whirlpool Thermal Fuse Kit âŁWorks Insideâ the Appliance: Electrical, Thermaland Airflow Integration
The 675813 Whirlpool Thermal Fuse Kit contains a thermal cutoff element and associatedâ harness â˘components âthat interrupt the dryer’s âŁheating circuit when cabinet temperatures exceed â˘a specified threshold. Electrically,â the thermal fuse is wired in series âwith the heating element (andâ in some designs a âŁsecondary safety⤠circuit) so that an open fuse removes voltage âŁfrom the heater assembly; this prevents sustained⢠overheating that⣠could damage âcomponents⣠or create a âfire hazard. Theâ kit is intended as a direct replacement âŁin compatible Whirlpool/Maytag models, so technicians should match connector type âŁand the temperature rating stampedâ on the component to the appliance’s service literatureâ before installation.
Thermally and⣠aerodynamically, the⢠fuse’s effectiveness depends on its mounting location relative to theâ heatâ source âand the dryerâ exhaust âairflow. Theâ device⤠senses localized âŁcabinet temperature rather than burner or element surface âtemperature, so reduced airflow or⣠a âblocked â¤vent⤠raisesâ the surrounding âair temperature and âŁcan âtrip the fuse even if the element itselfâ appears intact. Practical diagnostics â¤thus pairâ a continuity check of the fuse with verification of âvent flow, lint buildupand⤠blower⤠function; replacing the fuse âwithout correcting venting orâ recirculation âfaults commonlyâ results in repeat failures.
- Verify OEM part numberâ and temperature rating before âreplacement.
- Perform continuity testing with the dryer disconnected from power.
- Inspect andâ clear exhaust venting and⢠blower housing when a thermal cutoff has opened.
- Confirm correct âŁmountingâ orientationâ and secureâ connector fit toâ ensure reliable temperatureâ sensing.

Common Failure Symptoms and Diagnostic Indicators forâ a Faulty Thermal⢠Fuse Kit
The 675813 âWhirlpool Thermal Fuse Kit contains a thermal âcutoff âdesignedâ to interrupt the â˘dryer’s âheating circuit when the internal temperature exceeds safe limits. In normal operation the thermal fuse presents very lowâ resistance â˘and â¤provides a direct âpath for âŁcurrent âto the heating element; when the âdevice reaches its trip threshold it becomes an open circuit to prevent continued heat generation. Technicians should confirm model compatibility against the dryer’s service sheet⢠before installing the kitand understand âŁthat the âŁfuse is a passiveâ over-temperature safety device-it doesâ not reset and must â¤be âŁreplaced if âblown. âtypical âŁfield context includes dryers that tumble but do â˘not produceâ heat,⤠or systems where âintermittent over-temperature events have already caused additional component stress.
- No heat â˘while the drum tumbles or the⣠motor runs.
- Intermittent heatingâ or heated cycles â˘that stop unexpectedly.
- Burnt odor, visible charring near the fuse⢠housingor signs of vent restriction upstream of theâ fuse location.
- Dryer trips an upstream⢠circuit breaker or blows fuses only âŁwhen the heater is energized.
| Item | Description |
|---|---|
| Continuity (cold) | Good fuse: near 0 Ί; failed fuse: open/infinite Ί. |
| Voltage at âfuse terminals â¤(with heater call) | Correct supply voltage indicates downstream fault; â˘no voltage indicates an⤠upstream control⣠or safety device issue. |
| Common root causes | Blockedâ venting, â¤failedâ heating element creatingâ localized overheatingor cumulative lint buildup causing sustained high âtemperatures. |
Diagnostic verification âbegins with⤠safe isolation of power, access to the thermal fuse â¤locationand a â˘continuityâ check usingâ a multimeter; a reading of infinite resistanceâ confirms the fuse has âoperated âand needs replacement. If âthe fuse checks good âelectrically but heating⣠problems persist, measure voltage at the⢠fuse during a heat call-absence âof voltage points to a failed âŁtimer, moisture sensor, high-limit thermostat,⤠or wiring/connectors upstream â¤rather than the fuse itself. Recording these electrical signatures and correlating â¤them âwith physical evidence (discoloration,â sootor âvent blockage)⣠provides â¤a practical troubleshooting path that prevents unnecessary âpart âswaps and ensures the 675813⢠Whirlpoolâ Thermal Fuse Kit⣠is used appropriately as the corrective âcomponent when the â˘thermalâ cutoff has actually operated. â¤
Replacement Considerations and Installationâ Procedures for⣠the 675813 âŁWhirlpool Thermal Fuse kit (Compatibility and â¤Safety)
The â¤675813 Whirlpool Thermal⢠Fuse â˘Kit is a⣠one-time thermal â˘cutoff designedâ to interrupt the dryer’s heating circuitâ when internal âtemperatures exceed a prescribed safety threshold. In practice the device is⤠a âfail-safe placed inâ series with the heating element and will present continuity when cold and an⣠open circuit after⤠it has activated; âŁitâ does notâ reset. Technicians â˘should verify compatibility withâ the appliance modelâ and service âmanual because connector style,mounting â¤bracket,and temperature cutout rating can⢠vary âbetween models. A common⢠field symptom that indicates the thermal fuse has opened is â¤a dryer âthat tumbles but produces no⣠heat; a⣠quickâ continuity check with âa multimeter across the fuse âcontacts will confirm âŁits state before⢠replacement.
- Disconnectâ power â and confirm no⤠voltage at the appliance â¤before accessing the fuse location.
- Inspect the housing and wiring for heat⤠damage or â˘lint accumulation,which are âfrequent causes âof premature fuse activation.
- Replace only with⣠the same rated 675813 Whirlpool Thermal Fuse âKit â˘orâ OEM-specified equivalent; do not âbypass or âŁsubstitute a different cutout temperature.
- After replacement,verify heating circuit continuity and ârun the â˘dryer whileâ monitoring⣠vent airflow and thermostat operation toâ address root causes.

Q&A
What is the 675813 Whirlpool Thermal âFuse Kit?
Theâ 675813 Whirlpool Thermal Fuse kit isâ a one-time-use safety device⣠designed for certain⤠Whirlpool (and⣠related âŁbrand) clothesâ dryers. it interrupts power âŁto the dryer’s heating circuit if the dryer overheats, preventing fire or furtherâ damage. The kit typically⤠includesâ the thermal âfuse and â¤anyâ small mounting hardware or connector neededâ for installation.
How do I⤠know if the â˘thermal âfuse has failed?
commonâ symptoms of aâ blownâ thermal fuse include the dryer running but not â¤heating, âthe â¤dryer starting âbut stoppingâ shortly⢠afteror the dryerâ not starting in some models where âthe fuse⣠also protects the⢠motor or⣠control⣠circuit. Before concluding the fuse is bad, â˘rule out a tripped âŁcircuit âŁbreaker, a brokenâ heating element, a failed high-limit thermostator⣠severely restricted âŁventing,â as those conditions can⣠also cause similar âsymptoms.
How do I test the â¤675813 thermal fuse?
Unplug the dryer (and âturn off â˘gas supplyâ for gas dryers) â˘and access the thermal fuse. Remove theâ wiring â¤connectorsâ from â¤theâ fuse and useâ a multimeter setâ toâ continuity âor resistance â(ohms). Aâ good thermal fuse⤠will show near 0â ohms (continuity). If the meter shows âinfinite â¤resistance âorâ no continuity,the fuse is blown and must beâ replaced. Do not â˘test or replace with power connected.
How do I replace the 675813 thermal âfuse?
Turn off â˘and unplug the⤠dryer (and â˘shut⢠off gas if applicable).Access âŁthe fuse – typically located on⤠the⤠blower housing or nearâ the heating element â- âŁby removing⢠the appropriate panels. Disconnectâ the wiring harness or⤠pull off â¤the spade terminals, remove the âmounting screw/clamp, âand swap in the new fuse⢠from âthe kit. Reattach the wires, reassemble the dryer, restore powerand⢠test. If you are not comfortable working on âappliances, â¤hire a qualified technician.
Whatâ tools â¤and parts⢠do âI need âŁtoâ replace it?
Basic tools usually include âŁa screwdriver or nut driver set to remove panels and the mounting screw,⤠needle-nose pliers for connectorsand a multimeter â¤for testing.â The 675813 kit should include the⣠fuse and any required⤠smallâ hardware;â verify contents before starting. always have the dryer model number on hand to confirm correct â¤part â¤compatibility.
Why did the thermal fuse blowand will âreplacing it â¤fix the âroot cause?
The thermal fuse blows when â¤the dryer overheats. Common causes include restricted venting (clogged lint trap or exhaust vent), a failed âheating â˘element that shorts or overheats, a â˘stuck â¤high-limit thermostator poor airflow due to a blocked âblower.Replacing the fuse will ârestore â¤the safetyâ device,â but you âŁmust correct the âunderlying cause (clean vents,⣠repair heating element or thermostat) or the new fuse may blow again.
Is the thermal fuse resettable, â˘and can I bypass âit?
The 675813 thermal â˘fuse is non-resettable and must⣠be⢠replaced if it has opened. You shouldâ never bypass the thermal fuse â˘- bypassing removes âa critical â¤safety device and creates a â¤serious fire⢠risk. Only install the âcorrect replacement part âŁto ensure safe operation.
