137032600 Frigidaire Washer Dryer Thermal Limiter is a temperatureâoperated safety device âŁused in Frigidaire washerâdryer combinations. It âis a thermalâ limiter (a â˘highâlimit thermostat/thermalâ cutoff style⢠component) that senses local air or component temperatureâ and opens the electrical circuit when a⤠predefined temperature thresholdâ is âexceeded.â Physically the limiter is typically a small, twoâterminal sensing element mounted to the heater housing, blower housingor exhaust âŁpath and is specified by its thermal trip point and electrical ratings rather than by⣠mechanical function alone.
insideâ the appliance the thermal limiter functions as a secondary safety interlockâ for the heating system: when local temperatures riseâ above the device setpoint it interrupts power to the heater circuit (and in some designs can isolate other heatârelated circuits) to prevent âŁoverheating. It operates alongside âprimary control elements suchâ as cycling thermostats,control board relays,the heating element assembly,blower and vent â˘system,and door or moisture sensors; the limiter provides a failâsafe independent cutout that trips if normal temperature control fails or if ventilation is compromised.
This article will âdescribeâ the limiter’s electrical and thermal function, âtypical locations and mountingand how to verifyâ compatibility with Frigidaire assemblies⣠using⢠the 137032600 designation. It âŁwill cover common â¤failure symptoms (for â˘example openâcircuit limiter, no heat with motor runningor visible heat âdamage), diagnostic checks a technician can perform âŁto isolate âthe âlimiter versus upstream⢠causes, âand considerations forâ replacement such as âmatching temperature and current âŁratings,⤠correct âmounting and connector typeand addressing root causes â¤like restricted ventilation â˘or a âfailing heating element. The guidance âŁis presented âfor use âby technicians, engineers, âandâ informed appliance âŁowners who need to identify, evaluateand â˘specify the correct âsafety limiter for safe appliance operation.

Function and Role of the thermal Limiter in WasherâDryer Heating and Safety Circuits
137032600 Frigidaire Washer Dryer Thermal Limiter âŁis a temperature-actuated safety device placed in series with the⤠dryer’s heating element and its controlâ circuitry to interrupt power if âŁenclosure or element temperatures exceed a specified limit. In normal operationâ the limiter â˘provides a conductive path that allows âthe heater relay â˘or⤠timer to energize the element; if the sensed temperature reaches the device’s trip threshold the limiter opens the circuit andâ prevents furtherâ heating. As different Frigidaire modelsâ use either singleâuse thermal cutouts or resettable limit thermostats, replacement parts must âŁmatch the original limiter’s electrical rating, trip temperature, mounting styleand connector type to maintain correct behavior and safe integration with the control board and interlocks.
Technicians can diagnose limiter faults with a continuity check (with mains⢠disconnected) and by inspecting for heatâdamage, discolorationor a mechanically⢠openâ switch. Typical field âsymptoms include loss of heatâ whileâ the rest of the machine powers normally, â¤repeated premature shutdownsor a permanentlyâ openâ circuit at the â¤limiter even after the system⢠cools. Replace the limiter with a part that matches the manufacturer’s specification rather than⣠relying on a generic substitute; incorrect trip⤠points or ratings can⣠either allow unsafeâ overheating or cause nuisance cutouts.
- Heater won’t energize while motor and controls run normally
- Continuity reading shows open at ambient temperature
- visible heat damage or melting on the limiter housing or terminals
- Intermittent âheating that⢠stopsâ once⣠a threshold temperature is reached

How the 137032600 Frigidaire Washer Dryer Thermal Limiter Operates Within the Heater, Thermostatand Control Circuitry
The 137032600 Frigidaire Washer Dryer Thermal Limiter isâ a temperature-actuated safety device mounted â¤in the âheater assembly to interrupt power when the heater or surrounding air exceeds its calibrated trip point. Functionally it is indeed placed in series with the heating element and âfrequently enough with the high-limitâ thermostat so that⢠an overtemperature condition opens theâ limiter and removes voltage from the element or the heater relay. Replacement compatibility requires matching the limiter’s trip temperature, terminal styleand current rating to âthe original âŁappliance specification; â˘some limiters are single-use thermal fuses that must â˘be replaced after a trip, while others are resettable designs, so consult the service documentation or part datasheet⤠before âŁsubstituting components.
Within â¤the control circuitry the limiter provides a direct hard-safe interrupt that doesâ not rely⤠on software:⢠the main control â¤or âheater relay âwill apply power when a heat call is present, but if the limiter is open the heater⢠will â¤not receiveâ current and the⤠control will⤠detect⤠the absence of âexpected heating (sometimes via current sensing or through temperature feedback). Technicians typically verify operation by measuringâ cold continuity across the â˘limiter with a multimeter-an open âŁreading at ambient temperature⢠indicates a tripped or failed limiter.Repeated or premature trips point to upstream causes such⣠as a shorted âelement, restricted⢠airflow, âŁor faulty thermostatâ sequencing rather than a bad âŁlimiter alone, so diagnostic checks should include âthe element insulation, air pathand thermostat⤠contacts.
- No heat while⢠control âŁcalls for heat (open limiter).
- Limiter normallyâ closed at ambient; opens at its trip temperature.
- Must match trip temp and terminal type for safe replacement.
- Frequent trips suggest heater, thermostator airflow faults upstream.

Common â˘Failure Symptoms,Measured⢠Electrical Signatures,and Thermal Thresholds Indicating aâ Faulty Limiter
The 137032600 Frigidaire Washer Dryer Thermal Limiter is a temperature-actuated safety device installed in the heater/airflow path to interrupt â˘the heater circuit when⤠enclosure or air temperatures exceed safe limits. In operation it⢠behaves as⣠a fixed-threshold cutout rather than⤠a temperature-control thermostat: under normal ambient conditionsâ the limiter presents continuity across its terminalsand when the sensing element reaches its design trip temperature the internal contacts open to remove power from the heating â¤element. Compatibility is determined by OEM specifications and mounting/connector style; replace with the same⢠part â¤number⣠or an approved equivalent to preserve âthe⣠original trip⢠threshold and âmechanical fit. Verify whether the replacement unit is a ânon-resettable thermal fuse or an automatic-reset limiter beforeâ installation,â since the service response differs between one-time fuses and resettable thermostats.
Common failure symptoms include âcomplete loss of heating, heaters that shut offâ mid-cycle, âor repeat trips under normal load conditions; mechanical damage, meltingor discoloredâ wiring around the limiter are also diagnostic clues. Measured electrical signatures for a⢠healthyâ limiter â¤typically show near-zero continuity at ambient temperature (usually under a⤠few âohms for the contact path) âŁand an open circuit⤠(infinite resistance) after a âconfirmed over-temperature event or when the device has failed open.⣠Aâ practical â˘field check: âŁdisconnect power and the limiter, measure⣠continuity âcold, then âinspect for signs of overheating; if the limiter tests open at room temperature it should âbe replaced. Thermal thresholds vary by design and model-consult the â˘service manual-but a limiter âthat opens significantly below the published trip temperature or one that fails to open when the product reaches the⣠documented limit indicates a defective unit. Typical root causes producing false tripsâ include restricted venting, clogged â˘lint screensor failed airflow âcomponents âŁthat⤠raise cabinet temperatures above âŁthe limiter’sâ threshold.
- No heat or intermittent heating during âcycles
- Unit tests open â(no continuity) at ambient temperature
- Tripsâ only when dryer âis lightly loaded or â˘under normal use (indicating premature opening)
- Visible thermal damage, discolorationor melted terminals
| Item | Description |
|---|---|
| Expected⤠continuity (ambient) | <~5 Ί âacross terminals for⣠contact-style limiters; = near short-circuit for closedâ contact |
| Open state | Infinite âresistanceâ (OL) âafter trip or when⣠failed open |
| Typical tripâ temperature (reference) | Manufacturer âŁspecified; manny dryer limiters areâ in the order of ~150°C (â300°F) – verify the service manual for âthe exact value |
| Recommended action | Replace with identical part number⤠137032600 Frigidaire Washer Dryer thermal Limiter or OEM-equivalent; correct underlying airflow/venting faults before reuse |
Replacement Considerations, Model Compatibility, Installation Stepsand PostâInstall Diagnostics
The 137032600 Frigidaire Washer Dryer âThermal Limiter is a temperatureâsensitive safety device that interrupts the â¤heater/motor circuit when enclosure or component temperatures exceed its rated trip point. In normal operation the limiter â¤is a lowâresistance closed circuit; when theâ limiter opens it creates an open circuit that⣠prevents the âheater⤠from energizing and, in âmany models, disables dryer drive or âŁcontrol inputs⣠to avoid âdamage. Replacement must match the original part number or equivalent specifications for trip temperature, lead âŁlengthand mounting method as variations change the thermal response and mechanical âŁfit; consult theâ model service dataâ to confirm compatibilityâ before ordering⤠a replacement.
Installation and postâinstall diagnostics require systematic verification of the limiter âand the system that caused âits failure. ⤠Disconnect power and verify continuity ofâ the removed âlimiter with a multimeter before replacement, install the new limiter using the â¤original mounting⤠location and connector types to preserve thermal sensing and heat â˘sinking, then restore â˘power and run a monitoredâ heat cycle. If the limiter opens again,⤠measure vent resistance and airflow, inspect the heater element for signs of shortingâ or insulation breakdownand confirm that âŁthermostats and controlâ relays operateâ within specification; repeated trips⤠indicate an underlying thermal or airflow⢠fault rather than a defective limiter alone.
- Preâinstall check: continuityâ (closed) on the old limiter, note âwire color and routing.
- Installation: secure in⣠original position, use correct fasteners and connectors, avoid crushing the sensor element.
- Postâinstall tests: run a short heat â˘cycle, verify heater current⤠and vent airflow, check that limiter â˘remains closed.
- Troubleshooting:â repeated opens â inspect venting, heater element, thermostatsand control⣠board outputs.
| item | Description |
|---|---|
| Continuity (good) | Low resistance/closed âcircuit before tripping; confirms electrical integrity. |
| Trip behavior | Opens to interrupt heater/control circuit at specified temperature; consult service data for â¤trip point. |
