137392700 Frigidaire Dryer Heating Element Assembly is an electric resistance heating component used in frigidaire electric tumble dryers; the assembly typically comprises one or more coiled heating elements mounted in a metal housing with electrical terminals and often includes associated thermal fuses or mounting hardware. As a replaceable, serviceable assembly it provides the primary source of heat for the dryer and is identified by the manufacturer part number for ordering and compatibility checks.
Within the appliance, the heating element assembly converts electrical energy into heat and works in concert with the blower, drum, and airflow pathways to transfer hot air through the load. It interfaces with the dryer’s control system and multiple safety/temperature control devices-such as thermostats, high-limit thermostats, and thermal cutoffs-so that heating is modulated and interrupted when unsafe temperatures or fault conditions are detected.The assembly therefore sits at the intersection of the power delivery circuit,temperature regulation circuit,and the air handling subsystem of the dryer.
In this article readers will find a focused technical overview covering the heating element’s operational principles,common compatible appliance types and electrical characteristics,typical failure symptoms (no heat,intermittent heat,blown thermal fuse,visible coil damage),and a methodical approach to troubleshooting that differentiates element faults from airflow or control issues. The guide will also discuss replacement considerations-confirming part number compatibility, required precautions such as disconnecting mains power, inspecting associated safety devices and wiring, and verifying correct reassembly to restore reliable operation.

Functional Role and Thermal Performance Requirements of the Dryer Heating Element
The primary function of the 137392700 Frigidaire Dryer heating Element Assembly is to convert mains electrical energy into convective heat for drying loads while integrating safely with the dryer’s control and safety components. The assembly consists of resistance coils mounted in a steel housing,terminal connections,and mounting points that align with specific Frigidaire dryer chassis configurations. In operation the element produces hot air that the drum and blower circulate; the element’s electrical characteristics and physical mounting must match the dryer’s voltage,connector style,and thermostat locations to ensure correct heat output and reliable mechanical fit. Technicians selecting a replacement should verify that the assembly’s terminal layout and bracket dimensions correspond to the dryer model to avoid clearance or wiring mismatches.
Thermally,the element must achieve adequate surface temperature and heat flux while surviving frequent thermal cycling and brief over-temperature events until protective cutouts open.Key requirements include consistent power dissipation to maintain target air temperature, low thermal impedance to the housing for heat spread, and durable insulation of the coil leads against vibration and moisture. Practical diagnostic checks include continuity and resistance measurement (to confirm the element is intact but not shorted), inspection for coil breaks or hotspots, and observing drying performance: prolonged cycle times or cold drum airflow indicate reduced heating capacity, while nuisance breaker trips or blown fuses suggest a short or grounding fault. Replacement considerations also involve verifying that any included high-limit thermostats or thermal fuses are compatible and installed in the correct locations to preserve factory safety margins.
- Common symptoms of degraded thermal performance: longer dry times, partial heating, tripped house breaker, or visible coil damage.
- Checks a technician performs: continuity/resistance, visual inspection, and verification of correct voltage at element terminals.
- Compatibility factors: terminal type, mounting bracket alignment, and inclusion/location of thermal cutoffs.

How the 137392700 Frigidaire Dryer Heating Element Assembly Integrates and Operates Within the Appliance
The 137392700 Frigidaire Dryer Heating Element Assembly is a resistive heating module that integrates into the dryer’s rear or front bulkhead and ties into the appliance’s high-voltage line and control circuitry. Mechanically it mounts into a housing that channels heated air into the drum while electrically it sits in series with safety devices such as the thermal fuse and the cycling thermostat; the control board or timer completes the circuit to apply mains voltage to the element when heat is requested. Compatibility requires matching the element’s connector layout, mounting flange, and electrical rating to the specific Frigidaire model and the dryer’s nameplate voltage – replacing with an element of diffrent wattage or incorrect terminals can cause improper temperature regulation or create a safety hazard.
During operation the element produces heat when the control calls for drying and the thermal cutoff and cycling thermostat are closed; the cycling thermostat interrupts power to maintain target temperatures while the high-limit thermostat will open if overheating occurs. In practical troubleshooting, a technician will verify continuity across the element and its associated safety devices with a multimeter and inspect the element coil for breaks or overheating. Common diagnostic indicators include a drum that tumbles without heat,sporadic heating,or excessively long dry times; these often point to an open heating coil,a blown thermal fuse,or a failed cycling thermostat rather than the control board alone.
- Key electrical path: line → element → cycling thermostat → thermal fuse → neutral (or control relay depending on model)
- Installation checks: correct mounting orientation, secure terminal connections, and intact airflow path past the element
- Common diagnostic steps: visual coil inspection, multimeter continuity on element and fuses, verify voltage at element terminals during a heat cycle

Common Failure Symptoms, Electrical Faults and Diagnostic Indicators
The 137392700 frigidaire Dryer Heating Element Assembly is the resistive heating component that converts electrical energy into heat for tumble-dry cycles.The assembly typically consists of a coiled nichrome heating element supported within a sheet-metal housing, terminal connections for the line voltage, and mounting points that interface with the dryer cabinet and any in-line thermostats or thermal cutouts. Functionally, the element should present a measurable resistance between its two line terminals and an open circuit between the element and the metal housing; deviations from these electrical characteristics are the primary indicators of failure. Verify compatibility with the dryer model number and confirm how the assembly integrates with series thermostats and fuses, as many failures that appear to be the element are actually caused by external safety devices or a short elsewhere in the heater circuit.
- No heat while the drum tumbles – element has no continuity (open circuit) or a failed series thermal fuse.
- Weak or intermittent heat – partial breaks in the coil or increased resistance in the element causing reduced wattage and longer dry times.
- Tripping the household breaker when the heater engages – evidence of a short to ground or a direct short across line and neutral/line terminals.
- Burning smell, visible arcing, or discoloration – terminal connection failure, compromised insulation, or localized overheating of the element housing.
- Multimeter readings: expected finite ohms between element terminals and very high/OL between element and housing; any low resistance to chassis indicates leakage/short.
Technicians use targeted measurements to isolate faults: with the assembly disconnected, measure resistance across the two element terminals and then from each terminal to the metal housing to detect shorts to ground. A typical element will read in the single- to double-digit ohm range (varies by design), so an open (OL) across the terminals indicates a broken coil, while low resistance from terminal-to-housing indicates a short. If voltage is present at the element terminals during a heat call but no heat develops, trace the circuit to check thermal cutoffs, high-limit thermostats, and the timer/relay; if voltage is absent, the fault likely lies upstream (controls, fuses, or wiring). Physical inspection for snapped coils, burned spots, deformed housing, or compromised terminal insulation often corroborates electrical test results and informs whether replacement of the 137392700 assembly or upstream components is the correct repair.
| Item | Description |
|---|---|
| Typical resistance (approx.) | Single- to double-digit ohms (model-dependent); measure with power removed and element cold. |
| Expected supply | 240 VAC applied across the element terminals during a heating cycle on 240 V dryers. |
| Common diagnostic checks | Continuity across element, resistance to chassis (should be OL), visual inspection for breaks/arcing, verify series thermostats and thermal fuse. |
Compatibility Matrix, Replacement Considerations and Step-by-Step Installation guidelines
The 137392700 Frigidaire Dryer Heating Element Assembly is the resistive coil and housing that converts mains electricity into the hot air used to dry clothes. In operation the element works with the dryer’s thermal fuses, cycling thermostat, and blower to maintain set temperatures; common failure modes include an open coil (no heat), shorts to ground (tripped breaker), or physical deformation that restricts airflow.Compatibility is determined by electrical rating, terminal style, and physical fit - the element must match the dryer’s voltage and amperage, the spade or screw terminal layout, and the chassis mounting points so the housing seals correctly against the heater box and lint trap. Practical examples: a model designed for 240 V service will overheat or blow fuses if substituted into a 120 V circuit without verifying the rest of the control circuitry, and a mismatched mounting flange can prevent the thermal sensor from seating properly, causing incorrect temperature regulation.
Before replacing the assembly, follow safe diagnostic and installation practices: disconnect all power, verify the element is cold, document wire routing and take photos of terminal positions, check continuity across the coil with a multimeter, and confirm part compatibility against the dryer’s model plate and wiring diagram. During installation, route wiring to avoid contact with the heating coil, torque fasteners to maintain good grounding and sealing, and test the dryer on a timed cycle while monitoring current draw and temperature rise to ensure normal operation. Typical technical references helpful during replacement are summarized below to aid verification on-site.
- Compatibility checks: Voltage, terminal type, mounting dimensions, thermostat/fuse placement, OEM cross-reference.
- Diagnostic checks: coil continuity, insulation resistance to chassis, visible damage or hot spots, and correct blower airflow.
| Item | Description |
|---|---|
| Nominal supply | Check dryer rating plate for 120 V or 240 V; match element to system voltage. |
| Terminal & mounting | Verify spade size, screw locations and housing flange dimensions against the replacement part. |
Q&A
What is Frigidaire part 137392700 and what does the heating element assembly do?
frigidaire part 137392700 is an OEM electric dryer heating element assembly (the coil mounted in a housing). Its function is to convert electrical energy into heat to dry clothes. The assembly usually includes the heating coil, a retaining housing, and mounting/terminal points that connect to the dryer’s high-voltage supply and thermal cutouts.
How do I know if the heating element assembly has failed?
Common symptoms of a failed heating element assembly are: no heat at all, intermittent heating, very low heat, a buzzing/arcing noise from the back of the dryer, or visible breaks/burn spots in the coil. Also check for tripped circuit breakers and clogged venting-these can mimic a failed element. If the dryer runs but doesn’t heat, the element assembly is a likely suspect but you should also check the thermal fuse and thermostats.
How can I test the heating element assembly with a multimeter?
First disconnect power to the dryer. Remove the element assembly to access the terminals.Set a multimeter to the lowest ohms (Ω) range and measure resistance between the element’s terminal(s). A typical good electric dryer element will read roughly 10-30 ohms (varies by model and wattage), but check the service manual for the exact spec. Also test for shorts by measuring continuity between each terminal and the metal housing; there should be no continuity (open circuit) to indicate no short to ground.
Can I replace the heating element assembly myself, and what are the basic steps?
Yes, a mechanically-inclined homeowner or technician can replace it. basic steps: disconnect power at the breaker; unplug dryer (or switch off selector if 240V and unplug unavailable); pull the dryer away from the wall; remove the dryer access panel(s) to reach the element assembly (location varies by model-rear or front); disconnect wires and mounting screws holding the assembly; remove the old element, install the new assembly, reconnect wires to correct terminals, reassemble panels, restore power, and run a test cycle. Take photos of terminal wiring before removing for reference.
What safety precautions should I take when replacing the heating element assembly?
Always disconnect electrical power at the breaker before beginning work. Wear gloves and eye protection to avoid cuts from sharp sheet metal. Do not bypass or defeat thermal fuses or thermostats-these are safety devices. Be careful with residual heat if the dryer was recently used. If you are not comfortable working with 240 V appliances, hire a qualified technician.
What should I check if I replace the element but the dryer still won’t heat?
If a new element doesn’t restore heat,check the thermal fuse (blown fuses are a common cause of no-heat),high-limit thermostats,cycling thermostat,and wiring connections. Verify the dryer is receiving proper voltage (both 120V legs for an electric dryer). Also inspect the vent/duct for severe blockage and confirm the control board or timer is functioning. Use a multimeter to test continuity of the thermal fuse and thermostats.
How long does replacing the heating element assembly usually take and how much does the part cost?
Replacement time for a competent DIYer or technician is typically 30-60 minutes depending on model access. Part cost varies by supplier and region, but expect the OEM assembly to be in the range typical for dryer heating elements-check current retail prices from appliance parts suppliers. Labor costs apply if you hire a technician.
