137032600 Frigidaire washer Dryer Thermal â¤Limiter⤠is a temperatureâsensitive safety device designed to â¤interrupt electricalâ power to theâ dryer’s heating circuit when air⤠or component temperatures âexceed âa specified threshold.â As a thermal cutoff/limiter,the component is intended to prevent sustained overheating by opening the circuit at a predetermined temperature; inâ appliance practice this function might potentially be implemented as a oneâtime thermal fuse⤠or âas âa resettable highâlimit âthermostat âdepending âon the specific model and manufacturing run.
Installedâ typically⤠on or near the heating element housing,blower housing,or exhaust duct,the⣠thermal â˘limiter monitors localized air or⢠housingâ temperature and is wired in â¤series wihtâ the heater and control relays. âIt interacts directly with âthe heating element, cycling⤠thermostat(s), blower/vent system and the control⤠board: when⣠the limiter opens, power to the heater is âremoved, which stops furtherâ temperature âŁrise.correct operation therefore depends not onyl on the limiter itself but also⣠on proper airflow,element condition,and control logic; conversely,limiter trips⤠oftenâ indicate downstream problems⣠such as restricted venting,failed elements,orâ control faults that cause excessive run temperatures.
In this article you⣠will find a technical overview ofâ how the 137032600 thermal limiter functions, guidance onâ compatibility and specification checks, âtypical failure â˘symptoms â(for example, noâheat or intermittent heating and evidence of overheating), âand diagnostic approaches a technician or technicallyâsavvy owner⣠can use to isolate the limiterâ from other causes. The article also covers practical â˘replacementâ considerations â- â¤matching temperature ratings and electrical âratings, connector and mounting requirements,â and safe handling and â˘installation practices – to ensure the replacement restores intended thermal protection⣠without⤠introducing new hazards.

Function and Role of the Thermal Limiter in WasherâDryer Thermalâ Management
the 137032600 Frigidaire Washer Dryer Thermal Limiter â is a temperatureâsensing safety device âŁinstalled in the dryer section â¤to interrupt the heater circuit if temperatures exceed its design threshold. In normal operation the limiter remains closed and allows the heatingâ element to receive power;â if overheating occurs the limiter opens (often as a nonâresettable âthermal cutoff) and removes power âto the heater âto prevent thermalâ damageâ or âfire. Technicians⣠shoudl treat the⤠limiter as part â˘of the⤠unit’s overâtemperature protection âchain: its behavior is⤠dependent on correct mounting â˘and thermal contact to the heater â¤housing, âand it must be replaced with a part that matches âthe OEM temperature rating, current capacityand terminal configuration forâ reliable âcompatibility⣠and safeâ operation.
- No heat while drum âŁtumbles: a commonâ symptom âof an open âthermalâ limiter⣠that has interrupted the heater circuit.
- Intermittent trips:⢠usuallyâ indicate a secondary fault such as restricted airflow, â¤clogged âlint screen/vent,â failed blower motor, â¤or âŁa faulty cycling âthermostat rather than a failing âlimiter alone.
- Continuity test when cool verifies limiter condition; an open circuit â˘at room temperature means⢠replacement isâ required.
When servicing, confirm the limiter’s printed temperature and amperage ratings and match the terminal styleâ and mounting clip to â¤ensureâ mechanical and electrical compatibility; installing an incorrect limiter can allow unsafe temperatures or nuisance trips.⢠Practical troubleshooting â¤steps include checking venting and airflow first, measuring continuity on theâ suspected⢠limiter when the unit is coldand inspecting adjacent⤠components (heater element,â thermostat, wiring) â˘before replacing the limiter. After replacement,verify proper airflow⤠and perform âa short heat â¤cycle to confirm the problem âwas not caused by âŁan unrelated⣠failure that would cause the new limiter to open asâ well.

How the 137032600 Frigidaire Washer Dryer Thermal âLimiter Senses Temperature and Interrupts⢠Heating Circuits
The 137032600 Frigidaire Washer Dryer Thermal Limiter isâ a temperature-sensing safety device wired in â˘series with the dryer’sâ heatingâ circuit so that any over-temperature condition immediately interrupts power to the heater. In operation the limiter âbehaves as a normally closedâ element⣠at operating â˘temperature and⢠opens when its â˘calibrated trip âpoint is reached,removing current from the heater⢠element or the heater âŁrelay coil. Depending⢠on the specific design it may be âa single-use⤠thermal cutoff or a âresettable thermostat-style âlimiter; installersâ must verify the exact specification and mounting âorientation forâ compatibility with the appliance chassis and⣠wiring harness âbefore replacement. In practical terms,the limiterâ protects against sustained high temperatures caused by airflow blockage,a shorted element,or failed âŁcycling⣠controls,and it will typically show continuity⢠with âa cold ohmmeter and read open after a verified⢠over-temp event.
For â˘diagnosis and service, âŁtechnicians âtreat theâ limiter as a series âŁsafety âdevice: âloss of âŁheat combined âwith an open reading across the limiter is a strong â˘indicator â˘that the device has â¤tripped or failed and needs â¤replacement rather thanâ repair. Do not bypass âtheâ limiter; bypassing masks root causes and defeats theâ safety function. âWhen fitting a replacement,⣠match the part number, mounting bracket, connector style and trip characteristicsâ to theâ original part. Common field⣠symptoms and practical checks include visual signs of thermal damage at the limiter, continuity measurement cold (near âŁ0 Ί)and â¤recreating⣠the fault â¤condition safely âŁby measuring temperature âand current flow at the âheater circuit whileâ observing theâ control board and relays for⤠proper interruption behavior.
- No heat while the dryer â˘runs but âblower and drum motor⣠operate ânormally
- Continuity open at ambient temperature indicates a â¤tripped or failed limiter
- Visible discoloration, melted housingor corrosion â˘at terminals suggests thermal or electrical damage
- Intermittent heating⢠can indicate a marginal limiter or⣠poor connector contact

Common Failure Symptoms and⣠diagnostic Measurements â˘for⤠Thermal Limiter Faults
The component labeled 137032600 Frigidaire â¤Washer Dryer Thermal â¤Limiter functions as a temperature-actuated protective device in the heater circuit of compatible Frigidaire combination washer-dryer units. It is intended⢠to open the â¤circuit âwhen the⤠local temperature exceeds⤠its rated⤠trip pointâ to prevent overheating of â˘the heater assembly and surrounding insulation. Some thermal limiters are single-use â¤thermal fuses (open permanently when tripped) while⤠others are âŁresettable limit thermostats;⤠confirm the replacement part’s specification â˘and mounting orientation to ensure electrical and âthermal compatibility âwith the applianceâ model before⤠installation.
Common indicators⢠of aâ failed thermal limiter include complete loss⤠of heat while the drum⢠still tumbles, intermittent heatingâ that ceases after the unit warms upor a⣠unit that âwill not power the⢠heater element âdespite⤠proper supply voltage.Diagnosticâ measurements typically start with a⢠cold continuity check: with power âremoved and the limiter âdisconnected from âthe harness, a functioning â˘limiter shows continuity (near 0 Ί) and a âŁfailed limiter shows open circuit â(infinite resistance).For further isolation⤠measure âŁincoming heater-circuit⤠voltage at the limiterâ terminals during a heat call-presence of voltage with⤠the limiterâ open points to aâ failed limiter,⣠whereas⣠absence of voltage suggests upstream control or safety interlocks âareâ at fault.
- Symptom: No heat – Measurement: Continuity check across limiter â˘= open (OL)
- Symptom: Intermittent heat – Measurement: Continuity fluctuates â¤or opens⢠at elevated temperatures
- Symptom: Heaterâ receives no voltage – Measurement: Verifyâ supply voltage at âlimiter input âduring⢠heat âcycle
| Item | Description |
|---|---|
| Normal (closed) | Continuityâ present (â0 Ί) at room temperature; âallows heater circuit to be energized |
| Openâ / failed | Infinite resistance (OL); prevents voltage from reaching the heating element |
Replacement⢠Considerations,⤠Model Compatibilityandâ StepâbyâStep Installation âŁGuidelines
The 137032600 Frigidaire Washer Dryer Thermal Limiter is a temperatureâsensitive safety device installed in the heater/tub area to interruptâ power when âinternal temperatures⣠exceed its â˘design threshold. In operation the limiter provides a normally closedâ circuit at ambient temperature and opens irreversibly (or at a defined⣠reset point for resettable designs)⣠when âexposedâ to excessive heat, protecting the heater element â¤and wiring from â¤thermal damage. When â¤evaluating replacementâ compatibility, verify the limiter’s mounting bracket, terminal type (pushâon⤠spade, solder lug, etc.)and thermal trip rating against the appliance’s âservice manual; mismatched trip temperatures or physical fittings can allow unsafe operation or nuisance trips.⢠Common field symptomsâ indicatingâ limiter failure âinclude complete loss of heating with â˘powerâ present at âother heater â¤components, âor a continuous open â˘circuit on a cold continuity checkâ of the â˘limiter itself.
- Mounting and bracket orientation – must⤠match⣠existing housing cutout.
- Terminalâ type and⣠wire gauge⤠compatibility â- ensures secure electrical⢠connection.
- Trip â˘temperature and resetâ behavior – oneâtime⣠fusible vs. resettable limiter.
- Manufacturer part number crossâreference – confirms electrical and mechanical equivalence.
For⣠safe replacement, first disconnect⣠all power at âthe breaker or unplug the appliance, then access the heater assembly per the model’s service instructions. Document âŁor⣠photograph wire positions before removal,â remove âthe retaining screwâ or clipand compare the old and âŁnew parts âfor identical terminal spacing and trip ratings; install the ânewâ limiter⤠inâ the same orientation âŁand secure it to⢠the bracket, reconnect wires to the⤠corresponding terminalsand verify continuityâ at ambient⣠temperature with a⤠multimeter (closed) and that the heater â˘circuit⣠is complete only when appropriate control outputs are enabled. After reassembly, ârun a controlled diagnosticâ or short heating⣠cycle âwhile â¤monitoring for normal behavior – no persistent open circuits, no smoke or burning⣠odorsand expected heater current – and recheck mounting âŁand âwiringâ if anomalies â¤appear.

Q&A
What is the 137032600 Frigidaire washer/dryer thermal â¤limiter â˘and what does it do?
The 137032600 is a âŁthermal limiterâ (often called â˘a thermal fuse or thermal cutoff) used on âfrigidaire washer/dryer âŁcombos⤠andâ some dryers.⣠Its job is to protect the dryer/heater⣠circuit and motor from overheating⢠by â¤opening â˘the âelectrical circuit if âthe âtemperature exceeds a âŁsafe⣠threshold.This⣠prevents fires and damage â˘to âother components.
What symptoms indicate â˘the âthermal limiter has failed?
Common symptoms of⣠a failed â˘thermal limiter include: dryer runs but produces no heat, intermittent heating, the dryer stops mid-cycleor the âunit won’t run the heating circuit⣠at all. As the limiter opensâ the circuit when blown, you will typically measure no â¤continuity through itâ if it has failed.
Where is the thermal limiter located on a Frigidaire washer/dryer?
Location varies by model,⤠but the thermal limiter is usually âŁmounted on or â¤near the â¤heater assembly⢠or blower housingâ in the dryer⣠section âof âtheâ unit. Onâ stacked washer/dryer âcombos itâ can be accessed behind â¤a rear or lower front service panel. Always â˘consult your model’s⤠serviceâ manual⢠orâ parts diagram to find the exact mounting location.
How can a technician⤠test the 137032600 thermal limiter?
With the â¤appliance unplugged and the limiter disconnected from the wiring, test itâ with a multimeter set to continuityâ or low ohms. A good thermal âlimiter will show âcontinuity (close to â0 ohms); an openâ circuit â(infinite resistance) indicates the limiter has âblown âand needs replacement. Always â˘remove powerâ before⣠testing and take care when accessing âŁinternal components.
Is the 137032600 thermal limiter resettable or repairable?
Most thermal limiters used⤠as safety devices are non-resettable one-time â˘thermal fuses and cannot be repaired or reset. If the part âis open/failed, it should be replacedâ with the correctâ OEM part. âsome temperature-control thermostats are⢠resettable, so verify the component âtype for yourâ model⤠before assuming replace-only.
Whatâ commonly â˘causes the thermal limiter to⤠blow?
Typical causes include ârestricted airflow⤠(clogged lint filter or venting), a shorted orâ failed heating element, faulty cyclingâ thermostatsor prolonged high-temperature operation. Addressing the underlying cause (cleaning vents, replacing a bad heating element âor thermostat) is crucialâ when â¤replacing the limiter so the new part does âŁnot fail again.
Can I bypass the thermal limiter to get the dryer working?
No. Bypassing or shortingâ a thermal limiter⢠is unsafe âŁand can create a serious âŁfire hazard. Theâ limiter âis a critical⢠safety device; if it has âopened, you should replace itâ and âŁcorrect the overheating cause rather than bypassing the part.
