137392700 Frigidaire Dryer Heating Element Assembly is an electric resistance heating module designed for use in compatible Frigidaire residential dryers. The assembly typically consists of a coiled heating element, mounting bracket, insulating supportsand connection terminals; it is a replaceable service part that generates the heated air necessary for the dry cycle in an electric dryer (as opposed to a gas burner assembly used in gas dryers).
Inside the dryer, the heating element converts incoming electrical power into heat and interacts directly with the dryer’s electrical supply, thermostat(s), thermal cutout or thermal fuse, control board, drum and blower assemblyand the exhaust/venting system.It must reach and maintain target temperatures while the blower distributes heated air through the drum and out the vent; the element’s operation is governed by cycling thermostats and safety cutouts that open on overtemperature conditions and by the control electronics that time or sensor-control the dry cycle. Proper airflow and venting are also essential for safe, efficient operation as restricted exhaust increases element temperature and can trip safety devices or accelerate failure.
In this article readers will find a technical overview of how the 137392700 heating element functions, guidance on confirming compatibility with specific frigidaire models, common failure symptoms (no heat, intermittent heat, tripped thermal fuses, visible damage or short-to-ground)and practical troubleshooting tests such as continuity and voltage checks. The article will also cover replacement considerations – including power isolation, inspection of associated thermostats and thermal fuses, airflow and vent checks, and correct mounting and insulation - so technicians, engineersand appliance owners can make informed repair or service decisions without relying on non-technical guidance.

Function and Operational Role of the Dryer Heating Element Assembly
The 137392700 Frigidaire Dryer Heating Element Assembly is the resistive element module responsible for converting electrical energy into the thermal energy required to dry laundry. The assembly typically contains a coiled resistance element mounted within a stamped housing that directs heated air into the drumand it interfaces with the dryer’s control system through thermostats, the thermal fuseand the cycling control. Compatibility for replacement depends on the mounting flange, connector type and airflow path; technicians confirm fit by matching the dryer model and part number, verifying harness terminals and mounting holes before installation.
During normal operation the element is energized when the control calls for heat and cycles on and off under the control of the temperature-sensing thermostats to maintain set temperatures. The assembly’s operational behavior is directly affected by airflow and safety devices: restricted ventilation can cause localized overheating and a blown thermal fuse, while a broken coil presents as an open circuit and a complete loss of heat. Common diagnostic steps include a continuity check across the element, an insulation-to-chassis test for shortsand a visual inspection for broken coils or burned insulation. For example,a dryer that tumbles but produces no heat frequently enough has either an open heating element,a blown thermal fuse,or an open thermostat; confirming which item has failed guides whether the entire assembly or an ancillary safety component must be replaced.
- No heat: open element or blown thermal fuse.
- Intermittent heat or partial heating: intermittent coil contact, poor terminal connectionor thermostat cycling early.
- Tripped breaker or ground fault: element shorted to chassis or damaged insulation.
- Overheating: restricted airflow or failed high-limit thermostat.
- typical technician checks: continuity, ground insulation, terminal conditionand airflow path.

How the 137392700 Frigidaire Dryer Heating Element Assembly Integrates with Controls, Heating Elementsand Airflow
The 137392700 Frigidaire Dryer Heating Element Assembly is the central thermal-generating module that the control board energizes through relays or solid‑state switching. When the control calls for heat, line voltage is routed to the element terminals while temperature safeties-such as the cycling thermostat, high‑limit thermostatand one‑time thermal fuse-monitor envelope temperature and interrupt power if thresholds are exceeded. the assembly mounts directly in the air stream and uses exposed resistance coils enclosed by a perforated housing; correct harness mating and orientation are required for electrical compatibility and for the thermostats and thermal fuses integrated into or attached to the housing to provide accurate feedback to the dryer controls.In practice, installers shoudl verify mechanical fit, terminal spacingand harness connector type against the dryer model to ensure proper electrical and thermal integration.
Airflow and control behavior together determine delivered drying performance: the blower moves air across the heated coilsand the rate of air movement sets the temperature rise for a given coil wattage. Restricted airflow (clogged lint screen or duct) increases static pressure and can drive local hot spots that trip the high‑limit safety,while excessive airflow reduces dryer temperature and can extend cycle time. Troubleshooting typically focuses on three interfaces-electrical continuity of the coil and thermal cutouts, correct 240 V supply to the element terminals under a heat calland unimpeded intake/exhaust airflow. Useful checks include measuring continuity through the heating element and thermal fuses, confirming control outputs energize the element during a heat cycleand inspecting the housing alignment with the blower; common symptoms such as no heat with normal tumbling frequently enough trace to an open thermal fuse, a failed elementor a control that never supplies voltage.
- Verify continuity across the heating coil and each thermal cutoff.
- Measure line voltage at the element terminals during a heat demand.
- Inspect blower housing alignment and ducting for airflow restrictions.

Diagnostic Indicators and Common Failure Symptoms of the Heating Element Assembly
The 137392700 Frigidaire Dryer Heating Element Assembly contains the resistive coil, ceramic insulators, terminal block, and mounting cage that generate and position heat inside an electric dryer. This assembly is an OEM-style replacement that matches the original element’s mounting and electrical characteristics for compatible Frigidaire/Electrolux electric dryer models. Functionally, the coil is a low-resistance heating conductor that dissipates electrical power as heat; the housing and insulators control airflow and prevent arcing or contact with other components to maintain safe operation.
failure symptoms can be electrical (open or shorted coil), thermal (local overheating, thermal fuse trips)or mechanical (broken supports, damaged terminals).Technicians should check for continuity across the element and inspect for visible breaks,discoloration,or arcing at the terminals; a normal element for a 240 V dryer typically measures in the tens of ohms,so readings far above or showing an open circuit indicate a faulty element. Practical indicators include extended drying times, no-heat runs with the drum still turning, repeated thermal-fuse failuresand burning odors; as safety devices frequently enough fail after element problems, verify the thermal fuse and high-limit thermostats as part of the diagnosis.
- Clothes remain damp after a full cycle or drying times greatly increased.
- Dryer motor runs but no heat is produced.
- Tripped circuit breaker, blown thermal fuseor repeated thermostat trips.
- Visible damage: broken coil, blistered insulation, sootor arcing marks at terminals.
- Intermittent heating or uneven heat distribution across the drum.

Replacement Considerations,Required Parts,and Installation Procedure for the Heating Element Assembly
The 137392700 Frigidaire Dryer Heating Element Assembly is the resistive coil and support housing that converts supplied electrical energy into the convective heat used to dry laundry. The assembly typically includes the nichrome heating element, a metal mounting bracketand connection lugs; some variants also carry one or more temperature-sensing devices such as a high-limit thermostat or thermal cutoff. Functionally, the element should present low resistance when cold and heat uniformly across the coil; an open circuit, localized hot spots, broken supportsor intermittent continuity indicate failure. Verify compatibility by matching the part number, mounting flange geometry, terminal type (spade vs. screw)and rated voltage/current with the dryer model before replacementand inspect related components (thermal fuse, cycling thermostat, blower housing and venting) since restricted airflow or failed safety devices can produce similar symptoms.
Replacement requires basic electrical diagnostic skills, the correct spare partsand simple mechanical disassembly. Prior to any work, disconnect power and confirm isolation; check coil continuity with a multimeter and measure continuity of adjacent thermistors or fuses. When reinstalling, route wiring and secure terminals to prevent chafing, torque mounting fasteners to avoid distortion of the heating coil housingand restore proper venting to ensure rated airflow. After reassembly, verify the heater circuit voltage under load and observe a short run cycle to confirm steady temperature rise and correct operation of limit controls; if the thermal fuse or thermostat shows out-of-spec readings, replace them concurrently to avoid repeat failures.
- Quick diagnostic checklist: open-circuit element, blown thermal fuse, inconsistent thermostat readingsor reduced airflow.
- Installation checkpoints: confirm part fitment, label and photograph wiring before disconnection, tighten spade terminals fullyand clear lint from the blower and ducting.
- Safety steps: disconnect power,use insulated tools for live checks only when absolutely necessary,and replace any heat-damaged wiring or insulation.

Q&A
What is the 137392700 Frigidaire Dryer Heating Element Assembly and what does it do?
The 137392700 heating element assembly is the electric heating component used in many Frigidaire (and some related brand) electric dryers. It contains the resistance coil (heating element) and the housing/mounting hardware that produces the hot air used to dry clothes. It does not apply to gas dryers, which use a gas burner and pilot system instead.
How do I know if the heating element assembly is bad?
Common symptoms of a failed heating element include no heat or very low heat, clothes taking excessively long to dry, visible break in the coil, a burning/electrical smellor the dryer tripping the house breaker (if the element is shorted to the housing). Though, similar symptoms can be caused by a blown thermal fuse, failed thermostat/relay, timeror blocked venting, so a proper diagnosis is required.
How can I test the heating element assembly safely?
Disconnect power to the dryer entirely (unplug or switch off the breaker). Remove the wires from the element terminals and use a multimeter set to continuity or ohms. You should have continuity between the element terminals (a low resistance reading – typically a few ohms to a few dozen ohms depending on the model). Also check for a short to ground by measuring between each terminal and the metal housing; that should show open/no continuity. An open circuit between terminals means the element is broken and needs replacement; continuity to ground indicates a shorted element that can trip breakers.
Can I replace the 137392700 heating element assembly myself?
Yes, a competent DIYer or technician can replace it. Basic steps: disconnect power,remove the dryer back panel (or front depending on model),disconnect the element wiring,remove mounting screws and replace the assembly,then reassemble. typical tools are screwdrivers and a nut driver. Always confirm you have the correct replacement part for your dryer model and follow safety precautions (power off and avoid sharp sheet metal).
Do I need any other parts when replacing the element (thermal fuse, thermostats)?
Not always, but it’s common to find a failed thermal fuse or high-limit thermostat when diagnosing a no-heat condition. If the thermal fuse or thermostats are open, they should be replaced. If the element failed due to overheating caused by a clogged vent or lint build-up, also inspect and clean the venting and lint trap. Many technicians replace the thermal fuse and high-limit thermostat at the same time if they are aged or show signs of failure.
Will the 137392700 fit my dryer model?
Compatibility varies by model and serial number. The safest approach is to check the dryer’s model number and compare it to the part listing or the manufacturer’s parts diagram. Many online parts suppliers will let you enter your full dryer model to confirm fit. Do not assume interchangeability without checking, as element housings and terminal locations can differ between models.
Why would the dryer trip the breaker after installing a new heating element?
If a new element instantly trips the breaker, it likely has an internal short where the coil is contacting the metal housing (or wiring was connected incorrectly). other causes include a defective element out of the box or a wiring fault in the dryer.Turn power off, inspect wiring and mountingand test the element for continuity to chassis (it should be open). If the element is shorted, replace it; if wiring or terminal connections are incorrect, correct them before restoring power.
How long does replacement usually takeand do I need any special tools?
Replacement time is typically 30-60 minutes for someone comfortable with appliance repair. No special tools are usually required beyond standard hand tools: screwdrivers, nut drivers (commonly 1/4″ or 5/16″)and a multimeter for testing. Always disconnect power before starting work and follow the service manual or step-by-step instructions for your specific dryer model.
