137392700 Frigidaire Dryer Heating Element Assembly is a resistive heating module designed for use in electric laundry dryers; it typically consists of a coiled heating element mounted on a support bracket with a terminal block and may include associated thermal cutouts or mounting hardware. As a core thermal generation component, the assembly converts incoming electrical energy into controlled heat that is directed through the dryer drum and exhaust system to evaporate moisture from the load. The part is ordinarily installed in the rear or lower interior of Frigidaire-brand dryers (and compatible models) and is critical to achieving proper drying cycles and maintaining safe operating temperatures.
Within the appliance the heating element assembly interfaces directly with the incoming mains supply and the dryer’s control system (timer or electronic control board), and it works in conjunction with temperature regulators such as operating thermostats, high-limit thermostats, and thermal fuses. It is indeed also functionally linked to the blower and drum systems that provide airflow and to moisture or cycle sensors that terminate heating at the end of a cycle. Failures or faults in the element can affect these systems-causing no heat, intermittent heating, nuisance trips of thermal safety devices, or electrical faults that may open circuits or trip breakers-so understanding the mechanical mounting, electrical connections, and the airflow path around the element is crucial for diagnosis and repair.
In this article readers will find a technical overview of the element’s operation, guidance on checking compatibility with specific dryer models, common symptoms of failure, and methodical troubleshooting steps such as continuity and insulation tests, voltage verification at the element terminals, and inspection of thermostats, thermal fuses, and wiring. The piece will also cover practical replacement considerations-safety precautions, verifying part numbers, required tools, and reassembly checks to ensure proper airflow and grounding-so technicians, engineers, and appliance owners can evaluate faults and perform service with an understanding of both electrical and thermal safety implications.

Function and Thermal Role of the Dryer Heating Element Assembly
the 137392700 Frigidaire Dryer Heating Element Assembly is the resistive heating module that converts electrical energy into the process heat used to dry garments. The assembly typically contains a coiled nichrome element supported on insulating mounts and enclosed in a sheet-metal housing so that incoming air from the blower passes over the hot element and is carried into the drum.Its electrical and mechanical interfaces-terminal type, mounting flange position, and airflow orientation-must match the dryer chassis and control wiring; incorrect fitment alters airflow, changes surface temperature, and can prevent thermostatic control from operating correctly.practical troubleshooting examples include an open element producing no heat, a shorted element tripping household breakers, and a partially damaged coil creating hot spots that can prematurely trip thermal cutouts.
Thermally, the element’s role is to reach and maintain a target air temperature while cycling under control of the dryer’s thermostats and high-limit safety devices; cycling frequency depends on element wattage, motor air flow, and load moisture content. Common failure modes are open circuits from broken coils, grounding of the element to the housing due to insulation breakdown, and overheating caused by lint-restricted airflow. technicians should verify continuity and measure line voltage at the element terminals, inspect the housing for debris or arcing marks, and confirm operation of associated thermal fuses and thermostats before replacing the assembly. Below are typical symptoms and checks useful during diagnosis.
- No heat or intermittent heat - check element continuity and terminal voltage.
- Tripped breaker or blown fuses – inspect for short to ground on the element assembly.
- Overheating or repeated high-limit trips – examine airflow path and lint accumulation inside the element housing.

How the 137392700 Frigidaire Dryer Heating Element Assembly Works Inside the Appliance
The 137392700 Frigidaire Dryer Heating Element Assembly is a resistive heating module that converts electrical energy into heat inside compatible electric Frigidaire dryers. The assembly typically consists of a coiled resistive element (nichrome or similar), an insulated support frame, mounting brackets, and terminal connections; some configurations also include an integrated thermal cut‑out or mounts for separate thermostats. When 240 V is applied across the element terminals, current flows through the coil, producing heat that is transferred to the drum airflow by convection. Proper function depends on both the electrical continuity of the coil and correct mechanical fit and terminal orientation in the dryer – mismatched mounting or incorrect terminal spacing can prevent secure connections or interfere with air paths even when the element itself is intact.
Behavior under normal and fault conditions is deterministic and diagnosable: a complete open circuit in the coil produces no heat, a partially open coil can yield weak or intermittent heating, and shorts to ground will typically trip thermal protection devices or the house breaker. Technicians commonly isolate faults by confirming line voltage at the element terminals while the dryer is operating and then measuring coil continuity with a multimeter; an open reading indicates a failed element, while a very low resistance to chassis indicates a short to ground. Compatibility requires matching the assembly’s mounting style, terminal layout, and electrical rating to the dryer model – verify part cross‑reference and visually compare the assembly before installation to avoid fitment and safety issues.
- No heat: open coil or blown thermal cut‑out.
- Intermittent heat: partial coil break or poor terminal connection.
- Tripped breaker/short: element shorted to chassis or incorrect wiring.

Common Failure Symptoms and Diagnostic Indicators of the Heating Element Assembly
The 137392700 Frigidaire Dryer Heating element Assembly is the resistive coil and mounting structure that converts line-voltage electrical energy into the regulated airflow temperature required for drying cycles. A failed coil or broken lead will produce complete loss of heat, while partial breaks, intermittent contacts, or degraded coil resistance produce symptoms such as long dry times, reduced heat, or cycling that trips thermal cutouts. Compatibility matters: this assembly is designed to match specific Frigidaire dryer chassis and terminal configurations, so visibly similar elements or incorrect terminal layouts can cause incorrect operation even if the coil itself measures nominally.
Technicians diagnose the assembly with visual inspection and targeted electrical tests. Before any test, disconnect power and isolate the element connectors; measure continuity across the element terminals with a multimeter - a healthy heating element will show a low but finite resistance (typically a few to several tens of ohms depending on model and coil length), an open circuit indicates a broken coil, and measurable continuity from a terminal to chassis indicates a short to ground.Because thermostats, thermal fuses, and wiring are often in series with the element, a no-heat symptom should be traced sequentially: verify element continuity, then check in-line thermal cutouts and high-limit thermostats. Practical examples: an element that reads infinite ohms is a direct replacement candidate, while one that reads low resistance but creates a burning odor or trips a breaker should be removed and inspected for shorts to the metal housing.
- No heat or very long drying cycles despite normal blower operation
- Intermittent heating or cycles of heating followed by immediate cool-down
- Visible coil breaks, melted insulation, or burn marks on terminals
- Tripped thermal fuse or repeated high-limit thermostat trips
- Burning smell or smoke during operation
| Item | Description |
|---|---|
| Continuity across element | Low resistance (few to several tens of ohms) = element likely good; infinite = open/broken coil |
| Continuity to chassis | No continuity = normal; continuity = short to ground, replace element |
| Visual inspection | Broken coils, discolored or melted parts = replace assembly |
Compatibility and Model Fitment for the Heating Element Assembly
The 137392700 Frigidaire Dryer Heating Element Assembly is a resistive heating module that converts line voltage into the heated air circulated through the dryer drum. The assembly typically comprises the nichrome coil(s) mounted to a metal support plate, a terminal block for quick-disconnect connections, and a flow-oriented housing that directs heated air into the dryer duct. Proper mechanical fitment ensures the element sits in the correct position relative to the blower and thermostatic sensors; an incorrectly mounted element can cause restricted airflow, erroneous temperature readings, and premature failure of thermal cutouts.
compatibility is determined by both electrical and mechanical parameters: nominal voltage, element resistance (which scales with rated wattage), terminal type and spacing, mounting flange pattern, and the presence/location of thermal limit switches or fuses. Before installation, verify the dryer harness matches the element’s spade terminals, confirm mounting holes align with the cabinet, and measure coil continuity-the expected resistance for 240 V dryer elements commonly falls roughly in the 10-25 Ω range depending on wattage. Practical checks a technician uses when confirming fitment include matching part numbers or measuring terminal-to-flange dimensions,inspecting orientation of the airflow housing,and confirming that any built-in thermal fuses or sensors are compatible with the dryer’s control scheme.
- Electrical: 240 VAC nominal; verify coil resistance and intact insulation
- Mechanical: mounting hole pattern,flange orientation,and clearance for airflow
- Connections: quick-disconnect spade terminal size and position
- Safety: compatible thermal cutouts and accessible fuse locations

Q&A
What is the 137392700 Frigidaire Dryer Heating Element Assembly and which dryers is it used in?
The 137392700 is an electric heating element assembly (coil + housing) used in certain Frigidaire/Electrolux/related electric dryer models. It provides the resistive heating that dries clothes. It is not a gas burner part – it is only for electric dryers. Always confirm compatibility by checking your dryer’s model number against the part number in the manufacturer’s parts list or a trusted parts lookup before ordering.
What are common symptoms that the heating element assembly has failed?
Common signs include: the dryer tumbles but produces no heat or very little heat; intermittent heating; a burning or metal-smell while running; circuit breaker trips when the dryer runs; visible damage to the element (broken coil, burned or melted insulation). A blown thermal fuse or tripped high-limit thermostat can produce similar symptoms, so those should be checked as well.
How do I test the 137392700 heating element with a multimeter?
1) Disconnect power to the dryer. 2) Access the heating element terminals and remove any wiring if necessary. 3) Set the multimeter to continuity or low ohms. 4) Measure between the element’s terminals – you should see a low-resistance reading (continuity). An infinite/open reading indicates a broken (open) element. 5) Measure between each element terminal and the metal housing/chassis; you should see no continuity (very high resistance). Any continuity to chassis indicates the element is shorted to ground and must be replaced. Always follow lockout/tagout safety procedures when working on appliances.
Can the heating element be repaired, or must it be replaced?
Heating elements are normally not repaired; if the coil is broken, shorted, or shows burned/melted insulation, replace the entire assembly. Repair attempts are unsafe and unreliable. Replacing the element assembly is the recommended and standard practice.
Is replacing the 137392700 something a homeowner can do, and what precautions/tools are required?
Many homeowners with basic mechanical skills can replace this part. Required tools typically include a screwdriver, nut drivers, pliers, and optionally a multimeter. Precautions: disconnect power at the breaker before starting, wear gloves/eye protection, be careful of sharp sheet-metal edges, note wiring locations or take photos for reassembly, and verify other safety parts (thermal fuse, thermostats) are functional. If you’re not agreeable working with mains electricity or accessing internal dryer components, hire a qualified technician.
Will the dryer run if the heating element assembly is removed or broken?
Yes – on an electric dryer the drum and motor will usually continue to tumble if the heating element is removed or open, but the dryer will not produce heat. On gas dryers the operation is different as they use a gas burner assembly rather of this heating element.
Can a faulty heating element cause the circuit breaker to trip or damage other dryer components?
Yes. If the heating element shorts to the dryer chassis, it can draw excessive current and trip the home’s circuit breaker or blow fuses. Overheating or shorted elements can also cause thermal fuses or high-limit thermostats to fail, and in severe cases damage wiring or other components. If the breaker is tripping, stop using the dryer and investigate the element and wiring for shorts before continued operation.
How long does a heating element assembly usually last, and are aftermarket replacements acceptable?
Service life varies with usage and dryer conditions (venting, load type, and maintenance). Many elements last several years to a decade,but heavy use or blocked vents can shorten life. OEM (Frigidaire) assemblies are recommended for guaranteed fit and quality, but reputable aftermarket parts that match the exact specifications and mounting will also work. Always verify fit, ratings, and return policy before buying an aftermarket unit.
