675813⢠Whirlpool Thermal âŁFuse Kit isâ a thermal cutoff assembly usedâ toâ protect heating circuits in â˘householdâ laundry âappliances; it⢠is indeed a temperature-sensitive,â typically âsingle-use â¤thermal fuse â˘packaged with the âŁnecessary mounting hardware and connectors. Asâ a discrete protective component,the kit â˘contains⣠a thermal fuse that opens the electrical circuit when â¤a âpresetâ temperature threshold⢠is exceeded,preventing continued heating that could lead to âŁdamage or â¤unsafeâ conditions.
Inside âanâ appliance, theâ thermal fuse⤠is normally installed in series with the âheatingâ element or its control âcircuit and is positioned âwhere âit canâ sense airflow âŁand â¤temperature in the heater housing or exhaustâ path. â˘It âinteracts directly with the element, thermostats, temperature sensorsand the appliance control board:â when the measured temperature surpasses the fuse’s trip point, the fuse âŁbecomes an âopen circuit and interrupts power to the heater (and in some designs âto the driveâ motor or â¤control ârelays) until the faulty condition â¤isâ corrected and the fuse is replaced.â Proper function depends on correct placement, intact venting/airflowand compatibility of the fuse’s temperature rating and electrical connectorsâ with the appliance wiring harness.
Inâ this article you â˘will find a technical overview of the 675813 Whirlpool thermal Fuse Kit covering its âoperating principle âand typical specifications,⢠guidance on compatibility checks⢠and common âŁfailure âmodes, diagnostic indicators and⤠basic âtroubleshooting steps to confirm a failed fuse,⤠and practical considerations âfor replacement suchâ as âmatching trip temperature, terminal typeand mounting â˘orientation. The focus is on giving technicians, engineersand appliance owners the⢠context âŁneeded to identify⤠when this⤠component is implicatedâ in a fault and âhow âto verify that â¤a replacement part is⢠appropriate for the specific appliance model.

Functionâ and âRole of â¤the Thermal⢠Fuse in âDryer Overheat âŁProtection
The 675813 â˘Whirlpool Thermal Fuse Kit is a single-use â¤overtemperature device designed to interrupt the dryer’s heating circuit when internalâ temperatures exceed âthe fuse’s rated threshold. The thermal fuse is typically mounted onâ the blower housing orâ adjacent to the heating âelement and is wired in⣠series with âthe heater circuit so that when âŁit opens â¤it preventsâ the âelement from⤠receiving power. âA blown⣠thermal fuseâ presents âas⣠an ⤠open circuit whenâ measured with a multimeter;⤠because âthe device is⣠non-resettable, a failed fuse must⢠be replaced with a â¤part⤠that matches the original specifications to restore safe operation.
Technically, the thermal fuse is a⢠passive safety â¤component âŁthat responds toâ sustained overtemperature conditions rather âthan short transients; it will not protect⢠against⢠instantaneous electrical faults and therefore should âbe part of a broader diagnostic process. Commonâ practical âchecks include verifying continuity across⣠the fuse,inspecting the heating element for internal shorts that can cause overheating,and â˘clearing ventâ or lint⢠obstructions that raiseâ cabinetâ temperature.Typicalâ service indicators and âa brief â˘reference are listed âbelowâ to assist technicians in diagnosis and replacement decisions.
- Common symptoms: no heat while dryer motor â˘runs, dryerâ stops mid-cycleorâ an open reading on continuity⣠test.
- Diagnostic steps: unplug unit, âaccess â˘fuse â˘location, measure âcontinuity, inspect âŁvents â¤and element before⢠replacement.

How theâ 675813 Whirlpool Thermal Fuseâ Kit Works Within Dryer Heating and Airflow Circuits
The 675813 Whirlpool Thermal âFuse Kit provides one or more thermal cutoutsâ thatâ serve as a âŁfinal⣠safety device inâ the âŁdryer’s âheating circuit. installed in â¤series withâ the heating⣠element and downstream⤠of operating thermostats, âthe thermal fuseâ is normally âŁclosed and will⤠open irreversibly âwhen sustained⤠temperatures exceed its design threshold, promptly removing power toâ the heater to prevent overheating or fire. Because the âfuse âis singleâuse, replacing itâ restores⣠the electricalâ path butâ does notâ address âŁtheâ underlying cause of â˘the overtemperature⣠condition; technicians should â˘evaluate âairflow, lint âŁaccumulationandâ adjacent temperature controls âwhen a fuse has opened.
- Common⣠symptom:⢠drum tumbles but no heat,often with a âfuse showing no continuity on⢠a⣠multimeter⢠after cooling.
- Typicalâ placement:⣠mounted on the⣠heater box â˘or blower housing in series with⢠the heating element.
- Causes of nuisance opens: blocked venting,lint buildup,failed blower/element,or stuck thermostatsâ producing sustained high temperatures.
- Service note: replace⤠only⤠withâ an⣠equivalent thermal⤠rating and connector style to preserve â˘factory safety characteristics.
For â¤compatibility and practical⢠servicing,verify the âŁdryer’s wiring diagram and part number before replacing the⤠thermal fuse; the kit is intended to match factory thermal âcharacteristics for theâ specific models it covers butâ is not universal.⣠Diagnostic practice â¤is to disconnect power, âremove the âthermal fuseand check for ⢠continuity once the unit has cooled-an open⣠reading indicates the fuse has âŁoperated and must be replaced.After replacement,confirmâ free exhaust flow,clean the lint trap and â¤ductwork,and test â¤the heating circuit and thermostats,as repeated fuse failures almost always point to an â˘unresolved airflow restriction or a defective heating component rather than a defectiveâ fuseâ alone.

Common Failure Symptoms and âDiagnostic Indicators of a Faulty â˘Thermal â˘Fuse
The⢠675813 Whirlpool⣠Thermal Fuse Kit contains theâ thermal cutoff â˘element used to protectâ the dryer heating circuit by âŁinterrupting âŁpower âwhen enclosure temperature exceeds the⤠device’s rated threshold. Inâ normal operation the thermalâ fuse is a normally-closed âdevice⤠that âprovides a â˘low-resistance âŁpath; when it reachesâ its temperature limit it meltsâ an⤠internal elementâ and⣠becomes an open circuit, removing power⣠from the⢠heating element⢠or⣠control⢠circuit depending onâ the model. Compatibility of this⢠kit âŁwith âa âgiven dryer âdepends on⣠the âŁappliance model numberâ and harness configuration; âverify the â˘part number against â˘theâ service manual or OEM parts⤠list because different Whirlpool models⣠place the⤠fuse in different locations and⢠may use different mounting clips â¤or lead lengths.
- No heat while the drum tumbles (heater circuitâ open)
- Dryer willâ not start because the⤠fuse âŁisâ in a control/power feed
- Intermittent â¤heating or cycle termination mid-cycle
- Visible discoloration, melting, âor âphysical⤠separation at the fuse terminals
Diagnostic steps focus on continuity testing and inspection:⣠with power removed,â measure across the thermal fuse with a multimeter on the ohms rangeâ – a functional⢠fuse shows low resistance⢠(near 0 Ί), whileâ a⤠failed fuse reads⢠as an open or infinite resistance. Repeated or âŁrapid⣠fuse failures âindicate âŁa âroot cause âŁsuch âas restricted airflow, a failed heating element causing excessive local â˘temperatures,â orâ failed high-limit thermostats; replacing the âŁfuse without correcting those causes will⤠likely result âin anotherâ failure. Practical example: a dryer that runs but produces⤠no⣠heat frequently enough hasâ an open thermal fuse in the⤠heater housing, â¤whereas aâ dryer that does not power on at âall may have the fuse installed⢠in the âmain control feedâ and will also show open continuity⣠when â¤failed.

Replacement âŁConsiderations and StepâbyâStep Installation Procedure for the Thermalâ Fuse Kit
The 675813 â¤Whirlpool⣠Thermal Fuse Kit replaces a⢠single-use⤠thermal cutoff that protects the dryer from sustained over-temperature conditions by⣠opening âthe heating circuitâ (and inâ some âmodels, the motorâ circuit) when â˘internal temperaturesâ exceed the designed threshold. The⢠thermal fuse is a⣠normally-closed device at ambient temperature and must show continuity with âa handheld âŁmultimeter;⢠an open reading indicates the âŁdevice hasâ actuated and requires replacement. Compatibility âŁchecks before ordering or installing the kit should include matching âthe OEMâ part⢠number,â verifying â˘the terminal (spade) styleâ and wire â¤gauge on the harnessand confirming the physical mounting location onâ the blower housing or heating assembly so the replacement â˘will seat correctly and⢠route clear âof hot surfaces â¤or⣠moving parts.
- Disconnect power âand âconfirm de-energizedâ with a meter⢠or circuit tester.
- Access the fuse location (remove back panel or lower access panel) and visuallyâ inspect wiring and the⢠blower â¤housing for lint buildup or damage.
- Document or âphotographâ terminal orientation and harness routing⢠beforeâ disconnection.
- Measure âcontinuityâ across the â˘fuse; aâ functioning â¤fuse will read near 0 Ί when cold,⣠a â¤blown âfuseâ will read⤠OL (open loop).
- Install the 675813 kit â¤components, attach âspade â¤terminals in âthe original orientation, secureâ the fuse⣠to theâ housing,â and ensure the harness âis routed away from heat sources and⤠secured against vibration.
- Reassembleâ panels, restore power, â˘and run aâ short test cycle âto verifyâ heat-up and normal cycling while monitoring airflow⤠and ventâ exhaust âŁtemperature.
Practical considerations âduring replacement include cleaning lint from the⢠blower â˘housing and exhaust path before installation,as restricted⢠airflow âis aâ common cause of repeated thermal fuse failure; if the newâ fuse opens shortly after âreplacement,pursue vent⣠cleaning and blower/motor âinspection rather than replacing the fuse repeatedly. Use⣠a multimeter to⢠confirm⢠continuity âŁafterâ installation and check that⣠the replacementâ harness provides correct insulation and â˘connector fit; loose spade connectionsâ or⤠undersized wire canâ introduceâ additional resistance and âŁlocalized heating. For âdocumentation,⤠record the dryer âmodel and⢠serial number alongside the replacement date so future âservice⣠can quickly verify âwhether⤠the correct 675813⣠kit was âpreviously installed.

Q&A
what is⢠the 675813 Whirlpool Thermal Fuse Kit and what does it do?
The 675813 is a thermal fuse kit used in Whirlpool laundry appliances (typically âŁdryers). The thermal fuse is a one-time safety âdeviceâ that opens (cuts electrical âcontinuity) â˘when the appliance⢠or a critical component reaches an over-temperatureâ condition, preventing overheating and reducing fire risk. The kit may includeâ the â¤fuse and the ârequired wiring/fasteners for replacement.
How â˘do I âknow if⢠the 675813⤠is âŁthe âcorrect part for my âWhirlpool appliance?
Check your appliance’sâ model andâ serialâ number (usuallyâ on aâ tag inside the door opening or⤠onâ the back). Use â¤thatâ model number â¤to cross-reference parts in the âmanufacturer’sâ parts âlist or on a⢠trusted parts retailer site. âDo ânot rely only onâ similar appearance; confirm compatibility by model numberâ or OEMâ cross-reference data.
Whatâ are common â˘symptoms that the 675813 thermal âfuse has blown?
Typical symptoms⤠include: the⤠dryer âruns but â˘produces no heat, the dryer won’t startâ at allâ (if the fuse is âin the motor circuit), theâ dryer stopsâ mid-cycleor⢠it trips â¤a âcircuit. Note that severalâ faults can cause similarâ symptoms, so testing âthe â˘fuse and âchecking airflow/thermostats is âcritically important.
How can I test âthe 675813 thermal fuse to see âif it’s bad?
Always disconnect⣠power first.Access the fuse (usually on the blower âhousing or near the heating⣠element), then disconnect the⤠fuse leads. Use a multimeter â˘set to continuity or resistance. â¤A goodâ thermal fuse âshould show âcontinuityâ (very low ohms). If the âmultimeter⤠reads open/infinite resistance,⤠the fuse is blown and âneeds replacement. Verify wiring is disconnected before⢠testing⣠to avoid false readings.
can I âŁbypass the 675813 thermal fuse to make the applianceâ work?
No. Bypassing a thermal fuse defeats a critical safety device andâ creates a fireâ and âŁsafetyâ hazard.â Itâ is unsafe and should never⢠be done. If âtheâ thermal fuse has blown, replace â˘it with the correct OEM âpart and address the âunderlying cause of âoverheating.
How do I⤠replace the â˘675813 thermal â˘fuse kit?
Basicâ replacement steps: unplug the âappliance,â access the fuse location âby removing the required panel(s), note and photograph wire⢠connections, disconnect the âwires âŁand⢠remove â¤theâ old fuse, install the new⢠fuse andâ secure connectors/mounting per the kit, reassemble â¤panels, âŁrestore power and test. Also clean âŁlint and⣠check the vent âsystem and thermostats while âyou⤠have access.⢠If âŁyou’re not âagreeable⤠working on electricalâ appliances, hire a qualified technician.
What â˘commonly causesâ the 675813 thermal fuse to blow,⢠and how can I prevent future failures?
Thermal â˘fuses typically blowâ due⤠to sustained overheating. Common⣠causes are restricted exhaust/venting (lint blockages), â˘clogged lint screens, failing â˘thermostats âor cycling controls, overloaded loadsor poor airflow from long/poorly installed vent runs. Preventative⣠steps: cleanâ the lint trap each⤠cycle, regularly â¤clean the âŁdryer vent and ducting,â ensure proper vent length and routingand replaceâ failingâ thermostats or worn âcomponents promptly.
Is the 675813 thermal fuse a single-use part⣠and is âit safeâ to replace myself?
Yes – thermal fuses are single-use âdevices: once they open,â they must be replaced. replacing â¤the âŁfuse⢠is a common â¤DIY repair for those comfortable with basic electrical safety and appliance âdisassembly, âbut you must disconnect power and follow⣠instructions. If â˘unsure about diagnosis, safety procedures, âorâ wiring,⤠hire an appliance technician.
