137032600â Frigidaire Washer⢠Dryer âThermal Limiter⤠isâ a temperatureâsensitive âsafety component usedâ in â˘Frigidaire washerâdryer combinations and related⢠laundry appliances; it functions as a highâlimit cutoff (either⢠a oneâtime thermal fuse or a âŁresettable limiter depending on the design) that opens theâ heating circuit⢠when local temperature exceeds⤠a predefined⢠threshold. Asâ a discrete thermal cutoff/limit device it is⣠specified by âŁtemperature trip point, electrical ratingsand mechanical mountingand is identified âby the OEM âpart number for correct replacement and compatibilityâ verification.
Inside the appliance the thermal limiter is normally placed in series with theâ dryerâ heating⤠element or âcontrol circuit and monitors⣠temperatures at the heater âŁhousing,â exhaust path,â or drum area. It interacts directly with the heating assembly, primary thermostats, control âŁboard⤠and safety interlocksand indirectly with airflow components such as the blower, lint trap and venting;â inadequate⤠airflow, failed thermostatsor a⣠shorted heating element can cause âŁthe limiter to⣠operate. Its role is to removeâ power from the heater when temperatures rise beyond safe limits to protect wiring, cabinetâ components and the occupant from overheating or fire, âand to provide a âdefined failure mode for safety certification and diagnostics.
This article explains how the 137032600 thermal limiter functions, how to confirm compatibilityâ with âspecific Frigidaire models, common failure symptoms to watch for (such as, no heat, intermittent heator a permanently open circuit on continuity test)and practical troubleshooting â¤steps such as visual inspection, airflow â¤verification and multimeter testing. It will also cover replacement considerations including matching âŁtemperature ratings and electrical specifications, correct mechanical mounting and wiring practicesand safety precautions (power â˘isolation and using the specified replacement part) to⢠ensure âŁreliable and codeâcompliant repairs.

Thermal Limiter Function âand Role in Washer-Dryer Thermal Management and Safety
The⣠137032600 Frigidaire Washer Dryer âThermal Limiter is a temperature-actuated protective device installed on the heater assembly or in âthe exhaust path of select Frigidaire washer-dryerâ combinations. Its primary function is to interrupt the heating circuit when the â¤local temperature exceeds a designedâ cut-out threshold, preventing âŁthermal runaway, damage to surrounding componentsor a potential fire hazard. In most installations the limiter is mounted in direct contact withâ the heat source or ductwork so âit â˘senses⤠actual operatingâ temperature; many⢠designs âused in these appliances are ânon-resettable (one-shot) thermal fuses that require replacement after they open,even though some models use⤠resettable thermostats-confirm the specific âbehavior for the unitâ you’re servicing by checking part documentation and continuity with a multimeter.
During diagnosis, the limiter typically appears as an open circuit if it has tripped or failedand a loss of heat or âŁintermittent heating cycles are common symptoms. When replacing the limiter,match the replacement to the original in terms of cut-out temperature,current/voltage rating,lead length,and mounting style to preserve⤠correct thermal response and safe operation. Practical service steps âinclude verifying the limiter’s continuity withâ power removed, inspecting the mounting surface and thermal âŁcontact, checking for restrictedâ airflow or failed heating elements that could cause repeated⤠tripsand â¤using OEM cross-reference information when the exact âpart number â˘is not available.
- Symptoms: no âheat, intermittent heatorâ dryer tripping mid-cycle.
- Behavior: normally closed âat operating â˘temperature, opensâ at trip temperature; âmay be single-useâ or⤠resettable depending on design.
- Service checks: continuity test cold, inspect âmounting⢠and airflow, verify electrical ratings before replacement.
- Compatibility:â match cut-out temp, ratings,â and physical mounting for⣠safe replacement.

How the 137032600 Frigidaire âWasher Dryer Thermal Limiter Worksâ Inside the âAppliance
137032600 Frigidaire Washer Dryer Thermal Limiter is a temperatureâsensitive safetyâ device installed in the dryer section to interrupt the heater or heater-control circuit whenâ internal temperatures exceed âthe design âthreshold. Functionally it âis indeed â˘a â¤normallyâclosed thermal cutoff or limiter that opens the circuit at a specified temperature to prevent overheating and potential â¤fire hazards; in practice this part sitsâ on âŁor near the heater âhousingâ or exhaust path and directly senses air or component temperature. Compatibility is steadfast byâ electrical rating, tripâ temperatureand mounting style, so replacement must match the âoriginal part number and connector âtype for reliable operation-using the wrong limiterâ can change protection characteristics or create nuisance trips.
The limiter⣠behaves as a simpleâ binary device: closed â(low â¤resistance) at â¤ambient,then open when the trip temperature is reached. Technicians test it with⤠a multimeter across⤠its terminals â¤for continuity at room temperature and verify it opens âwhen heatedâ using controlled heat or a âservice oven⣠only when safe. Common â˘failure symptoms include the dryer âtumbling with no heat, intermittent heatingâ cyclesor aâ heat circuit that will not energize; these symptoms often follow vent blockages, failed blower motors, âŁor failed heating elements that push temperatures beyond the limiter’s threshold. Replace the limiter with the⤠exact OEM 137032600 part, disconnect mains power before serviceand âensure connector integrity and â¤insulation areâ restored to OEM â¤condition to avoid false readings or electricalâ faults.
- Symptoms: no heat, intermittent heatingor heater âcircuit openâ despite correctâ controls.
- Typical checks: continuity at ambient, insulation and connector inspectionand verifying⤠vent and heater condition before replacement.
- Installation notes: match part number, secure mounting âŁto âthe heater housingand restore proper wire routing to prevent thermal lag or heat soaking.

Common Failure Symptoms, Electrical Measurements and System-Level Effects
The 137032600 Frigidaire Washer Dryer Thermalâ Limiterâ is a temperature-actuated⤠safety device that interrupts theâ heater or associated⣠circuit when temperatures exceed the limiter’s rated threshold. It is â¤a normally âŁclosed thermal cutoff mounted on or near the heater⢠housing or blower plenum; under normal conditions⤠it conducts and allows the heating element âand thermal control circuits to operate. When âthe limiterâ reaches its trip temperature it opens the circuit to âprevent sustained overheating, protecting wiring, componentsand the cabinet. Replacement must match the original â˘part’s electrical ârating, terminal styleand trip specification â˘to maintain safe operation and compatibility with the appliance’s control âscheme.
Technicians verify limiter condition with simpleâ electrical âchecks andâ observation⢠ofâ system-level âbehavior. A cold, functional limiter will show near 0 Ί continuity withâ a multimeter and will become an open/infinite âcircuitâ after being heated past its trip point; â¤a⣠limiter that reads open at room temperature is failed and will âprevent the heater from energizing. âSystem symptomsâ include complete loss of heat, intermittent â¤heating, prolonged âcycle timesor âŁfault codes indicating overtemperature or heater faults;⣠in some configurations âa âŁtripped limiter can also prevent blower⤠or motor â˘circuits from running if the control interlocks the heater circuit. diagnose by measuring continuity at the limiter terminals, confirmingâ supply voltage at the⣠control harness during a âheat âcalland isolating the limiter from the rest of the circuit before replacement to avoid misdiagnosing upstreamâ faults.
- Symptom: No heat or intermittent heat; Measurement: continuity at room temp = near 0 Ί.
- Symptom: Prolonged âdry times or repeated cycling; Measurement: open circuit at room temp indicates failed limiter.
- Symptom: Appliance displays heater/overtemp errorâ codes; Measurement: verify supply voltage to limiter during call for heat.

Compatibility, Model Cross-Referenceâ and Replacement/Installation Considerations for theâ 137032600 Frigidaire â˘Washer Dryer Thermal Limiter
The 137032600 Frigidaire Washer â˘Dryer Thermal Limiter is a temperature-actuated safety device used to interrupt electrical power to heating elements or motors â¤if⤠internal⤠temperatures exceed a⢠designed threshold.Compatibility is âdetermined by three⤠primary factors: the thermal cutout temperature and reset behavior (one-shot fuse vs. automatic reset thermostat), the electrical ratings (voltage and current capacity)and the physical mounting and connector style. technicians should compare the OEM part number, âŁthe âstamped temperature â˘ratingand the terminal type against the original component; two limiters with identical shapes can have different trip temperatures or different reset âcharacteristics, âwhichâ will effect appliance protection and operation. For example, a limiter that⣠mounts to the dryer heater housing in compact washer-dryer combosâ may appear identical across models⣠but âmay have a different âcutout temperature that either nuisance-trips or fails toâ protectâ the heater if â¤mismatched.
Replacement and installation require verification and basic circuit testing before âand⢠after fitment. With power removed,check continuity across the limiter at ambient⣠temperature (expect near-zero resistance for normally closed limiters)⢠and confirm open-circuit after controlled heating only if theâ part is a one-shot device; consult the service manual for the specified trip temperature.During installation, maintain original lead routing,â use proper crimp or spade â˘terminals⣠sized for the âlimiter’s current ratingand secure the limiter to the same mounting surface to ensure correct thermal âcoupling and reliable operation. Installingâ a limiter â˘with a higher trip temperature can leave the appliance unprotected, while a lower trip temperature can cause repeated shutdowns; replace with âa verified cross-referenced part or⣠OEM equivalent âŁto preserve safe operation.
- Pre-replacement checklist: verify⤠OEM part number and temperature rating, inspect mounting tab and terminal type, measure continuityand document original lead lengths for reassembly.

Q&A
What is the 137032600 thermal limiter in âŁmy â˘Frigidaire washerâdryer and what does it do?
Theâ 137032600 thermal limiter is⢠a temperatureâsafety device (thermal fuse/thermal cutoff) used on frigidaire washerâdryer âunits to protect âŁthe⣠dryer/heating circuitâ from overheating.â If the dryer temperature exceeds the design limit (for example because of a blocked vent, âfailed thermostat, âŁor âshort), the limiter opens the circuit to shut off the heaterâ or dryer⣠motor andâ prevent fire or damage.
What are common symptoms that the thermal limiter has failed?
Typical⢠symptoms include the dryer not heating at all while the drum still âŁtumbles, the dryer stopping âŁmidâcycleor the unit not powering the heating element. You may also notice a recent history of restricted airflow (long drying times) or frequent overheating before â˘the â¤limiter blew. A failed limiter is usually an openâ circuit (no continuity).
Where is the thermal limiter located on âŁa Frigidaire washerâdryer?
Location varies by model, but the thermal limiter is commonly mounted on or near⢠the dryer’s blower housing or heater assembly on the rear or underside of theâ dryer section.On combo washerâdryersâ it may be behind a rear access panel or inside the dryer housing near the heating element or⢠air exhaust path. Consult the model’s tech sheet or service manual for the exact location.
How can I test the 137032600â thermal limiter to see if it’s bad?
First âdisconnect â¤power.Remove âthe accessâ panel to reach the limiter⣠and disconnect its wire connectors. Use a multimeter set to continuity or resistance:⤠a good thermal limiter should show continuity (very low ohms). An⢠open reading (infinite resistance) indicates the limiter has âblown. Do not test it while the unit is powered and â˘do not rely on inâcircuit readings – disconnect theâ device first.
Can I bypass the thermal limiter to get the dryer working?
No. Bypassing a thermal limiter is perilous as it removes an essential overheat protection and creates a serious fire risk. It may also void warrantiesâ and violate safety codes. If the âŁlimiter âis open, diagnose and fix the â¤root cause (blocked vent, faulty thermostat, failed heating element, wiring fault) and replace the limiter with the correct OEM part.
Isâ the thermal limiter resettable or a oneâtime âdevice?
Most thermal limiters used as âsafety cutoffs in dryers are nonâresettable thermal fuses (oneâtime devices). Once they open they must be replaced.Some machines use⣠thermostats that are resettable, but you should⢠checkâ the part number and service manual – for 137032600 treat it as a replacementârequired safety device unless documentation states or else.
What tools and parts do I need to replace the â˘137032600 thermal â˘limiter?
Basic tools: a screwdriver or nut driver âset to remove access panels,needleânose pliers to pull electrical connectors,and a multimeter to confirm the⣠old part âis â¤open.â You’ll need the correct replacement 137032600â limiter (order by the âŁappliance model and⣠part number to ensure compatibility). Optionally, take photos of wiring before disconnecting âŁto ensure correct âŁreassembly. Always disconnect power â˘before starting.
After replacing the thermal limiter, â¤do I need to âdo anything else?
Yes – âŁaddress and correct the cause of the overheating so theâ new âlimiter won’tâ blow instantly. Clean lint fromâ the dryer, clear and inspect the vent and exhaust âpath, verify â¤the blower and heating element âare functioning ânormallyand check thermostats and wiring.Run a test cycle and monitor drying performance. If the limiter blows again, further electrical orâ airflow diagnostics are required.
