137392700 Frigidaire Dryer Heating Element Assembly is a resistive heating assembly designed for electric clothes dryers; it comprises the heating coils and associated mounting and safety hardware housed within the dryer’s heater box. As a load-bearing electrical component, the assembly converts supplied electrical energy into heat via high-resistance elements and is typically supported by insulating retainers, a metal housing, and interfaces for electrical connections and thermal safety devices.
Within the appliance, the heating element assembly is the primary source of hot air and interfaces directly wiht the dryer’s power supply, temperature regulation and safety systems, and the air-movement subsystem. It is activated by control relays or contactors on the user interface or main control board and works in concert with thermostats,thermal fuses/limit switches and the blower assembly to maintain set temperatures and prevent overheating. Proper operation thus depends not only on the integrity of the heating element itself but also on correct electrical supply,intact safety cutouts,unrestricted airflow through the drum and venting,and reliable control signaling.
In this article readers will find technical coverage of the 137392700 Frigidaire Dryer Heating Element Assembly including its functional role, how to determine compatibility with specific dryer models, typical failure symptoms (for example no heat, intermittent heating, or nuisance tripping of thermal cutouts), and methodical troubleshooting steps such as continuity and voltage checks and inspection of associated safety devices. The article will also discuss practical replacement considerations-matching part numbers, safe isolation of power, inspection or replacement of related thermal fuses and thermostats, correct reconnection and mechanical mounting-and verification procedures to confirm safe, effective operation after service.

Function and Thermal Role of the Dryer Heating Element Assembly
The 137392700 Frigidaire Dryer Heating Element Assembly is the resistive heating component that converts mains electrical energy into the convective heat used to dry laundry. The assembly typically contains the metal heating coil, a support housing that channels airflow across the coil, and the mounting/terminal hardware that interfaces with the dryer’s power and control circuits. As current flows through the coil its temperature rises; airflow from the drum and blower carries that heat into the drum cavity. Proper mechanical positioning and intact insulation around the coil are required to maintain even heat distribution and to prevent short circuits or contact with the dryer cabinet.
Thermally, the heating element is one element in a control loop that includes thermostats, a cycling thermostat or control board, and one or more thermal cutouts. The element’s resistance and surface temperature determine heat output but the control system modulates run time to maintain target air temperatures and prevent overheating. Compatibility concerns include the element’s rated voltage/current, physical mounting, and terminal type-using the wrong assembly can lead to incorrect temperature behavior or tripped safety devices. Typical diagnostic cues for replacement are an open circuit on a continuity check,visible breakage or burned insulation on the coil,or repeated tripping of high-limit thermostats; technicians should verify element continuity with a multimeter and confirm that fuses,thermostats,and wiring are functional before replacing the assembly.
- Key features: resistive coil, mounting housing, electrical terminals, and airflow-facing design
- Common failure modes: open coil, short to ground, burned insulation, or broken terminal studs
- Service notes: check continuity, inspect for physical damage, and do not bypass thermal safety devices

How the 137392700 Frigidaire Dryer Heating Element Assembly Operates Within the Dryer’s Electrical, Airflow, and Safety Systems
The 137392700 Frigidaire Dryer Heating Element Assembly converts incoming electrical energy into thermal energy through resistance coils mounted within a sheet-metal housing; this assembly is wired into the dryer’s 240 V heating circuit and is switched by the dryer’s control system or thermostats. When the control calls for heat, current passes through the element windings and the assembly radiates and convects heat into the plenum; the control circuitry (timer, electronic control board, or cycling thermostat) modulates duty cycle to maintain set drum temperatures.Compatibility considerations include terminal layout, mounting dimensions, and nominal voltage-installing a physically similar assembly with different terminal configuration or rating can produce incorrect cycling behavior or immediate safety trips, so technicians should verify model cross‑references and wiring harness fit before replacement.
The heater assembly interfaces directly with the dryer’s airflow and safety subsystems: the blower draws ambient air across the glowing coils and into the drum, so adequate venting and an unobstructed lint path are required to carry heat away and prevent localized overheating. Safety devices such as the high‑limit thermostat and thermal fuse monitor element temperature and open the circuit if airflow is restricted or a coil fails shorted; a thermal fuse is a one‑time protective device and must be replaced if blown, while thermostats are typically reusable if within tolerance. For troubleshooting, inspect the housing for burned or broken coils, verify continuity across the element with a multimeter, check that thermostats and fuses are closed at ambient temperature, and confirm unrestricted ventilation-common failure modes include open coils from mechanical fatigue and element overheating caused by clogged vents or a failed blower.
- Common assembly components: heating coils, terminal block, mounting bracket; may be paired with separate thermal fuse and high‑limit thermostat depending on model.
- Operational dependencies: correct voltage and wiring, adequate airflow, functioning thermostatic safety devices.
- Typical symptoms of failure: no heat, intermittent heating, or thermal cutouts without long‑run heating.

Common Electrical and Mechanical Failure Symptoms and Recommended Diagnostic Procedures
The 137392700 Frigidaire Dryer Heating Element Assembly is the resistive heater pack that produces the drying heat in compatible Frigidaire electric dryers. It consists of a coiled nichrome or similar resistive element mounted in a sheet-metal housing, with terminals for line connections and frequently enough provisions for one or more thermal cutouts or thermostats depending on the assembly variant. Functionally, the assembly must provide a low-resistance, isolated heating path across the line terminals while remaining electrically isolated from the housing; its performance also depends on correct supply voltage and adequate airflow through the drum and lint pathway. For compatibility, match the dryer model and OEM cross-reference – physical mounting, terminal arrangement, and whether the assembly includes sensors or separate components can vary between models and replacements.
- No heat at all: dryer tumbles but produces no warm air.
- Partial or intermittent heating: heats weakly or cycles on/off unexpectedly.
- Overheating or frequent high-limit trips: dryer cuts out due to thermal limit activation.
- Burning odor, visible discoloration, or arcing noise: signs of damaged element coil or insulation breakdown.
- Excessive runtime with damp loads: often caused by reduced element output or restricted airflow rather then motor failure.
| item | Description |
|---|---|
| Heating element | Continuity across element terminals; expected low single- to low double-digit ohms. Open circuit indicates broken coil. |
| Thermal fuse/thermostat | Continuity test-open indicates blown fuse or failed cutout; replace as required. |
| Supply voltage | Measure ~240 V across element terminals on U.S. domestic dryers with the dryer running (or with load applied); no voltage points to line or door-switch/relay issues. |
Diagnostic procedure sequence: with mains power disconnected, perform a visual inspection for broken coils, soot, or melted insulation, then check continuity of the element and associated thermal devices with a digital multimeter; an open element requires replacement, while continuity to chassis (low resistance to ground) indicates a short and mandates replacement. Reconnect power only for live-voltage checks: verify full line voltage at the element terminals with the dryer calling for heat, and if voltage is present but the element remains cold, the element or its internal connections are defective. Also evaluate airflow and restriction-condensed heat or slow drying often stems from lint-occluded ducts or a blocked blower even when the element tests good-so include airflow verification (temperature rise across the heater under normal load) as part of the diagnostic sequence.
Compatibility, Replacement Considerations, and Step-by-Step Installation Requirements
The 137392700 Frigidaire Dryer Heating Element Assembly is a resistive heating module that converts incoming electrical energy into the convective heat used to dry clothes; the assembly typically includes the nichrome heating coil, mounting bracket, and one or more thermal cutouts or high-limit thermostats. Compatibility depends on mechanical fit, terminal type and spacing, rated voltage/wattage, and the presence or location of integrated thermal sensors. Technicians should verify that the replacement assembly matches the appliance model number or OEM cross-reference, that the terminal connectors align with the dryer’s wiring harness, and that the overall dimensions and airflow path do not interfere with drum clearance or venting, since a mismatched assembly can cause poor airflow, elevated temperatures, or mechanical interference.
Replacement requires safe isolation of power, verification of element continuity, and confirmation that associated controls (thermostats, fuses, and timer/controls) are functioning to avoid repeat failures. Use a multimeter to confirm continuity of the heating coil and test for shorts to chassis ground before and after installation; expected coil resistance is in the low tens of ohms for typical 240 V dryer elements, but always compare to manufacturer specifications.After installing the assembly and restoring power, run an initial no-load airflow cycle to confirm correct fan/airflow and then monitor temperature rise to verify proper heating; also inspect all wiring connections for secure crimps or screw terminals and secure the element mounting to prevent vibration-induced wear.
- Confirm fit: match part number/model and check bracket, terminal spacing, and sensor locations.
- Power off: disconnect mains before accessing the heater compartment.
- Document wiring with photos,then disconnect terminals and remove the old assembly.
- Measure coil continuity and insulation to chassis; replace if open or shorted.
- Install new assembly,secure mounting,reconnect terminals,and restore power for tests.
- Run no-load airflow test, then a short heat cycle while monitoring temperature and venting.

Q&A
What is the 137392700 Frigidaire dryer heating element assembly?
137392700 is an OEM Frigidaire electric dryer heating element assembly (the coil and housing that produce heat). It contains the heating coil mounted in a metal housing and the terminals/mounting points required to install the element in compatible Frigidaire electric dryer models.
Which Frigidaire dryer models is this part compatible with?
Compatibility varies by model and production year. This OEM part is used in many frigidaire electric dryers, but you should confirm fit by checking your dryer’s model number and the part cross‑reference from Frigidaire or an authorized parts supplier. Never assume compatibility based solely on visual similarity.
What are the common symptoms that the heating element assembly is failing?
Typical symptoms include no heat or weak heat,intermittent heating,dryer taking far longer to dry,a burning smell or visible charring around the element area,or the circuit breaker tripping when the dryer runs. Note that some symptoms can also be caused by a failed thermal fuse, thermostat, timer or blocked venting.
How can I test the heating element to know if it’s bad?
Always disconnect power at the breaker before testing. remove the element’s electrical connectors so you don’t measure through other components. Using a multimeter set to ohms, measure across the element’s two terminals-there should be continuity (not infinite). typical resistance for common 240 V dryer elements is on the order of 10-30 ohms (a 4,000 W element would be about 14.4 ohms),though values vary by design. Also measure each terminal to the metal housing/chassis; there should be no continuity (open). Continuity to ground indicates an internal short and a bad element.
Can I replace just the coil,or do I need to replace the entire assembly?
Most replacements are sold and installed as the full heating element assembly (coil plus housing and mounting brackets). While some technicians may be able to rewrap or repair a coil, replacing the full assembly is the usual, safest option to ensure proper fit, insulation and long‑term reliability.
What are the electrical specifications (voltage/wattage/resistance) for this heating element?
Electric dryer heating elements are designed for the dryer’s supply voltage (typically 240 V in the U.S.). Wattage for complete dryer heating elements commonly ranges from ~3,000 to 5,500 W depending on model. Resistance depends on wattage (R = V²/P) so a 4,000 W element at 240 V is roughly 14.4 ohms; many elements measure in the approximate 10-30 ohm range. For exact specs refer to the manufacturer’s documentation for part 137392700.
