137392700 âFrigidaire Dryer â˘Heating Element Assembly is an electric heating element module used in compatible Frigidaire electric tumble dryers. The assembly⢠typically consists of a high-resistance heating coil (commonly a nickel-chromium â˘alloy) mounted âin a sheet-metal housing or air shroud, with line-voltage âterminals and mounting points for integration into the dryer cabinet. As a replaceableâ assembly,it combines the resistiveâ element,protective housing,and frequently enough attachment points for temperature sensors or thermalâ cutouts into a single serviceable unit.
Inside the appliance, the heating element assembly⤠converts incoming electrical energy into thermal energy to raise the air temperature passing âŁthrough the drum; this âheated⤠air, circulated by the âblower, removes moisture fromâ laundry and carries it out throughâ the exhaust. The element interacts directlyâ with the dryer’s electrical supply, the blower and drum airflow systemand the temperature-sensing and safety devices (cycling thermostat, high-limit thermostat, thermal fuse or cutoutand control board). Proper operation depends on adequate airflow across the element, correct electrical connectionsand functioning safety sensors to prevent⤠overheating and to coordinate heating cycles.
In this article âyou will find a⣠technical overview of how the âŁ137392700 heating element functions, â˘guidance on verifying compatibility â¤with specific⤠Frigidaire dryer models, common failure symptoms (no heat, intermittent heat, weak heat, visible element damageor tripped thermal⤠safety devices), systematic⢠troubleshooting steps a â˘technician can apply (continuity and voltage checks,⣠inspection of associated thermostats and fusesand airflow diagnostics)and practical replacement considerations (matching part numbers and electrical ratings, correct mounting and wiringand safety precautions such as disconnecting power and replacing single-use thermal fuses).

Function and Role of the Dryer Heating Element Assembly in Heat⣠Generation and⢠Thermal Regulation
The 137392700 Frigidaire Dryer Heating Element Assembly â˘is the resistive heating moduleâ used in compatible electric dryers to convert electrical âŁenergy into âheat. The assembly typically contains a coiled heating element, a metal â˘housing that directs airflowand mounting terminals for the âline âand neutral connections; some versions include âintegrated terminals or connector tabs that mustâ match theâ dryer’s âwiring harness. Under normalâ operation the coil heats as current flows through its resistance; the housing channels incomingâ air across the hot âcoil and directs heated air into the drum. âCompatibility depends on matching voltage, terminal layout, âand housing fit-installing â˘an element with âthe wrong voltage rating or âincorrect terminals⤠can result in insufficient heat,⣠excessive âcurrent draw, blown fusesor unsafe⤠operation.
Thermal regulation for the assembly is achieved by interaction âwith thermostats, âa high-limit thermostat⤠(or thermal cut-out),â and the dryer’s control circuitry rather than âby the element itself. The high-limit thermostat and thermal fuse provide over-temperature âprotection: if airflow is⤠restricted or the heating coil draws excessive current, these âsafety devices openâ the âŁcircuit to prevent damage⢠or fire. Practical troubleshooting examples include measuring âŁcoil continuity⤠to confirm an open element, checking for short-to-ground with an insulation âŁtestand verifying that the high-limit orâ thermal fuse has not opened; a dryer⤠that runs but produces littleâ heat âmay have a partially shorted element or a failed âthermostat â¤rather than⤠a completely open coil. Typical symptoms and component roles are summarized below.
- No heat:â open heating coil âor blown thermal fuse.
- Intermittent heat or weak heat:⢠partial coil failure, poorâ terminal connectionor voltage imbalance.
- Tripping high-limit: restricted airflow, failed thermostat, âor mounting/housing âŁobstruction.

|---|---|
| Heating coil | Nickel-chromium resistive element⣠that produces heat when energized. |
| Element housing | Channels airflow and secures⤠the coil;⣠must fit the dryer âŁcabinet to ensure proper ventilation. |
| Thermal fuse / high-limit thermostat | Series safety devices that openâ the heating circuit on over-temperature conditions. |

How the 137392700 Frigidaire Dryer Heating Element â¤Assembly Works Within the Appliance: Electrical Connections,airflow Path,and â˘Control Interfaces
The 137392700 Frigidaire Dryer Heating Element Assembly is a service-replacement module that houses the âŁresistive heating coil and the mounting⢠structure that connects to the dryer’s line voltage and safety cutouts. In normal operation the control system (mechanical timer or electronic control â¤board)⣠switches line voltage â˘through aâ series of âsafety devices-thermal fuse, high-limit thermostatand âcycling thermostat-before energizing the element terminals. Technicians shouldâ verify that the replacement âassembly’s terminal layout,mounting holes,and any attached sensor clips match the dryer model because identical-looking elements can differâ in terminal spacing or integrated sensor placement; mismatched layouts⤠can prevent proper⣠connection or create unsafe wiring conditions âŁduring installation.
Airflow and temperature regulation are equally critical to the âŁassembly’s behavior: the dryer blower draws ambient airâ from the âdrum across theâ heated coil and expels â˘it through the⣠lint trap and exhaust, âŁso the element must be unobstructed and properly seated in âŁthe housing to avoidâ local overheating. âReducedâ airflow from lint build-up, a partially broken coilor an open thermal cutout⢠produces symptoms such as no heat, intermittent heator tripped safety devices; conversely, correct control interface function is verified by confirming the âcontrol supplies voltage to the element only when the motorâ and required thermostats are closed.â For practicalâ diagnosis,⢠check continuity of the coil⤠and each safety device âin-circuit, inspect terminal connections for corrosionâ or loosenessand compare the replacement part’s physical and⣠electrical fit to the dryer model before final installation.
- Electrical path and safety chain: line terminals ââ thermal fuses/thermostats â heating coil⤠â return
- Airflow path: drum â heating chamber (across coil) â lint filter â exhaust
- Common field checks: coil continuity, terminal integrityand airflowâ restrictions â(lint/exhaust)
| Item | Description |
|---|---|
| Terminals | Match spacing and number of connections to the dryer’s wiring harness and terminal block |
| Safety sensors | Thermal fuse and high-limit thermostat are typically in series with the element and must be compatible |
| Diagnostics | Measureâ element continuity and verify control applies voltage only when motor and⣠thermostats⣠are engaged |
Common Failure Symptoms âŁand Diagnostic Indicators: No Heat, Intermittent Cycling, Resistance Driftand Safety Cutouts
The 137392700 Frigidaire Dryerâ Heating Element Assembly is the resistive coil module that converts electrical power⣠into heat and â¤mounts into the dryer cabinet with specific terminal and chassis fits forâ compatible Frigidaire models. Technicians verify compatibilityâ by matching mounting points and terminal layout âŁrather than relying solely âon visual similarity; incorrect fit âcan leave elements⣠too âclose toâ chassis or âairflow ducts and â˘cause premature failure. Functionally â˘the element should present continuity⢠across its terminals â˘and an expected low-resistance value for a 240 V heatingâ circuit (often in the single- to low-double-digit ohms range depending on element design)and it must be electrically âisolated from the⣠metal housing;â a low⢠resistance to âground indicates insulation breakdown andâ requires replacement rather than âa temporary repair.
Common failure modes manifest as distinct measurable indicators:⤠an open coil produces no heat and measures infinite âresistance, âa coil partially degraded or âwith increasing oxide layers âwill show resistance drift upward over time and produce â˘longer dry cycles, intermittent heating âoften correlates with âloose terminal connections or â¤a failing cycling thermostat rather than the element itselfand safety cutouts â(thermal fuses, high-limit thermostats) will âopen when âoverheating occurs-often caused by vent restriction ârather â¤than the element. use a âmultimeter to check continuity between element terminals, check resistance trend against aâ known-goodâ sample or service specand measure resistance from each âterminal to chassis to detect shorts. Clean âthe venting and inspect wiring and connectors before replacing the assembly to avoid repeating failures.
- No⢠heat – open circuit on element terminals (infinite ohms) orâ open thermal fuse.
- intermittent⤠cycling â˘- loose terminals, failing cycling thermostator intermittent element contact.
- Resistance drift – gradually rising⣠ohms, reduced â¤wattageand longer â¤dry times.
- Safety cutouts tripping – high-limit thermostat/thermal fuse open due to overheating or restricted airflow.
| Item | Description |
|---|---|
| Expected continuity | Low ohms between element terminals; specific value varies by â¤design (single- to low-double digits âtypical). |
| Short to â¤chassis | Low resistance from terminal â¤to metal housing indicates â˘insulation failure; replace element. |
Compatibility, Replacement Considerationsand StepâbyâStep Installation Guidelines for 137392700 Applications
The 137392700 Frigidaire Dryer Heating element Assemblyâ is a modular coil-and-housing unit that converts mains⤠electricalâ energy âŁinto the thermal output required to dry fabrics.It typically mounts into the⢠dryer chassis with spade-terminal connections and integratesâ with the dryer’s high-limit and cycling âthermostats; correct fit â¤requires matching theâ housing mounting pattern, terminal spacingand voltage rating to âthe dryer model. In normal operation the coil presents a low butâ nonâzero âresistance and cycles⤠on and off under⢠control of âthe timer/thermostat network; common⤠failure modes include an open coil (no continuity), coil-to-housing â¤shorting (ground fault), broken terminal tabsor degraded insulation that allows intermittent âheating or tripping âof the âdryer’s thermal cutouts. Verify compatibility by cross-referencing the part number âŁand checking that the element’s terminal layout and mountingâ flange match the appliance model before installation.
- Symptoms âindicating replacement: no heat with blower⤠running, partial/weak heat, trippedâ high-limit thermostat, visible coil break or burned insulationor a multimeter reading of infinite resistance across âthe element.
- Required checks before fitment: confirm mains voltage (typically 240⤠V for US dryers), âŁcontinuity of the element, condition of thermostats⣠and thermal fusesand correct terminal type (female spade size).
- Installation considerations: avoid deforming the coil or âallowing it to contact the drum; secure⢠strain reliefs and grommets; route wiring to prevent chafingâ and ensure proper grounding of the âassembly.
| Item | Description |
|---|---|
| Voltage â˘rating | 240 V nominal for most Frigidaire electric dryers; confirm on machine plate |
| Electrical test | Continuity expected across element; open circuit indicates failure; short to chassis indicates grounding fault |
| Mounting/terminals | Flanged âhousing with spade terminals; match terminal spacing and âbracket âpositions |
For⤠replacement,first remove⤠electrical powerâ at the breaker and verify absence of voltage with a meter-do not proceed without this confirmation.â Access method varies by model (rear panel versus front access through theâ drum);â document or photograph wiring before disconnection, âremove retaining screws, extract the housingand inspect adjacent thermostats â˘and fuses so theyâ can be replaced if degraded. After fitting the⣠new 137392700 element, reconnect spade terminals snugly, reseal any insulation or grommets,⤠and perform a continuity check and an initial noâload âŁrun to confirm correct â˘cyclingâ and absence of earth leakage; if the element⢠runs hot promptly or trips limits, cut power â¤andâ verify correct orientation, undamaged insulationand that noâ coil is contacting the drum before returning⤠the dryer to service.
Q&A
