WB44X173 GE Range Oven Broil Element is a resistive heating component used in GE electric ranges to provide the oven’s broil function. It is indeed an oven cavity heating element that converts line voltage into radiant heat at the top of the oven, typically mounted across the upper rear or ceiling of the cooking chamber and connected to the appliance’s high-voltage terminals and mounting bracket.
Inside the appliance,the broil element interacts with the oven control (mechanical timer or electronic control board) and associated relays or switches that supply and interrupt power. It also operates in conjunction with the oven temperature sensor or thermostat and safety devices such as thermal cutouts and fuses; it’s condition affects how the control modulates broil cycles and contributes to overall cavity temperature distribution. Faults in the element can introduce electrical faults (open circuit, short to ground) or thermal irregularities that influence both broil performance and safety systems.
In this article readers will find a technical overview of the WB44X173 part including its function and typical installation locations, guidance on compatibility and model fitment, common failure symptoms to recognize (for example loss of broil, uneven browning, visible damage, or tripped protective devices), methodical troubleshooting steps (visual inspection, continuity and insulation checks, and verifying control outputs), and practical replacement considerations such as verifying part number, terminal and mounting style, safe power isolation, and post-replacement verification of operation. The focus is on technical facts and diagnostic steps useful to technicians,engineers,and appliance owners evaluating or replacing the element.

Function and Role of the Oven Broil Element in Heat Generation and Temperature Regulation
The WB44X173 GE Range Oven broil Element is a high-wattage resistive heating element mounted at the top of the oven cavity to produce intense radiant heat for broiling and browning. Electrically it functions as a low-resistance heating coil: when the oven control or broil selector applies line voltage, current through the element produces rapid thermal output. The element’s design emphasizes direct radiant energy rather than convective heating, so its effectiveness depends on clear line-of-sight to the food and correct positioning of the oven rack. Replacement elements must match the original part’s mounting, terminal configuration, and electrical characteristics to avoid improper fit, reduced performance, or overheating of control circuits.
Temperature regulation for broiling is typically handled by the oven control board or a dedicated broil thermostat that switches power to the element; many ranges use simple on/off cycling rather than precise closed-loop modulation, so broil performance is influenced by control logic, door position, and distance from the element. Technicians can verify element behavior by visual inspection (breaks,blistering),electrical checks (continuity and relative resistance compared with the original specification),and functional tests under load. Practical examples: use higher rack positions and shorter cycle times for direct searing, and use the broiler with the oven door slightly ajar only if the manufacturer specifies that configuration. Common indicators that the element is failing include uneven browning, weak or no heat, and visible damage.
- Features: high-wattage radiant output, top-cavity mounting, direct-line electrical connection through oven terminals.
- Symptoms of failure: open circuit on multimeter, erratic on/off behavior, visible breaks or hot spots on the tube.
- Service check: verify fit, terminal type, and continuity before installing a replacement part.

How the WB44X173 GE Range Oven Broil Element Integrates with the Range’s Electrical, Control, and Thermal Systems
The WB44X173 GE Range oven Broil Element functions as a resistive radiant heater that directly interfaces with the range’s high-voltage supply and the oven control system.when the control board or a mechanical broil selector energizes the broil relay or contactor, mains voltage is applied across the element’s terminals and the element converts electrical energy into infrared heat. Its electrical integration is primarily through the oven’s terminal block and wiring harness, while thermal integration depends on the element’s position in the oven cavity and the nearby insulating and reflective surfaces that shape the radiant pattern and heating rate. Physically and electrically compatible replacements must match the element’s mounting points and terminal arrangement to maintain connector integrity and predictable thermal response.
Control and safety systems monitor and regulate the element’s operation: the oven control board times and cycles power via relays or solid-state switches, the oven temperature sensor or thermostat provides feedback for closed-loop control, and high-limit thermostats or thermal cutouts interrupt power on overtemperature. Common diagnostic indicators of an electrical or integration fault include an open circuit (no continuity) at the element, a short-to-ground causing a tripped breaker, or control fault codes when the board detects unexpected current draw. Practical considerations for technicians include verifying continuity and insulation resistance with a multimeter, ensuring secure terminal connections at the terminal block, and checking associated safety devices; these checks help distinguish between a failed element, a control relay failure, or a sensor/thermostat issue that can affect broiling performance and safety.
- electrical interface: terminal block connection to mains and control relay
- Control behavior: relay/SSR cycling based on bake/broil commands and sensor feedback
- Safety integration: high-limit thermostats and thermal cutouts interrupt power on overtemperature
- Mechanical/thermal: mounting location affects radiant pattern and heating response

Common Failure Symptoms and Measurable Diagnostic Indicators for the Broil Element
The WB44X173 GE Range Oven Broil Element is a straight tubular heating element that provides concentrated radiant heat from the oven ceiling for broiling. It functions by resisting current flow and converting electrical energy into infrared heat; a healthy element will glow uniformly along its length and reach stable temperature within the expected broil cycle.Failure modes include an open filament (no continuity), increased internal resistance that reduces output and causes slow or uneven browning, insulation breakdown that creates leakage to chassis and trips protective devices, and localized mechanical damage such as blistering or deformation from repeated thermal stress. compatibility for replacement requires matching the element’s mounting configuration and voltage/wattage rating to the oven model specified by the OEM part number.
- Element shows no heat or very slow heat rise (open circuit or high resistance).
- Uneven broiling or hot/cold bands across food (localized element degradation or partial break).
- Arcing,visible sparking at terminals,or a burning smell (insulation failure or terminal corrosion).
- Circuit breaker trips or fuses blow when broil is selected (short to ground or severe leakage).
- Multimeter reads continuity to chassis (insulation breakdown) or infinite resistance (open element).
| item | Description |
|---|---|
| resistance (ohms) | Calculate expected R using R = V² / P. Example: a 2,500 W element on 240 V yields R ≈ 23 Ω; a reading far higher implies degradation,infinite indicates an open filament. |
| Leakage/short to chassis | Continuity between element and oven ground or low insulation resistance on a megohmmeter indicates a ground fault that can trip breakers and present shock risk. |
| Current draw | Use a clamp metre to verify operating current; lower-than-expected current indicates high resistance, higher-than-expected current indicates a possible short or incorrect voltage supply. |
Technicians confirm faults with simple, repeatable measurements: a digital multimeter for continuity and resistance, a clamp meter for operating current, and an infrared thermometer or thermal camera to verify uniform surface temperature during operation. Visual inspection of terminals for pitting, loose connections, or blistering is critical becuase poor connections raise contact resistance and produce localized heating that accelerates failure. For safe diagnostics, disconnect power before measuring insulation resistance or continuity to chassis, and compare measured values to the element’s rated wattage and supply voltage to determine whether replacement of the WB44X173 GE Range Oven Broil Element is warranted.
Replacement Considerations and Installation Procedure for Broil Element Assembly: wiring, Mounting, and Safety
The WB44X173 GE Range Oven Broil Element is a straight replacement heating element that converts electrical power into radiant heat for broiling operations.In normal use the element presents a low cold resistance (frequently enough in the low tens of ohms for a 240 V oven) and draws current only when the oven control or broil relay applies line voltage; an open or visibly blistered element, or one showing very high resistance on a continuity check, indicates failure.The part uses speedy-disconnect spade terminals and is engineered to match the mounting footprint and thermal clearances of the original GE assemblies, but technicians should confirm model compatibility and terminal orientation before installation to avoid incorrect connections or mechanical interference with oven racks and insulation.
- Power off at the circuit breaker and verify zero voltage at the element terminals with a multimeter before touching wiring.
- Document wire positions or take a photo so each quick-disconnect is reinstalled to the same terminal.
- Remove the mounting screws or clips that secure the element to the oven rear wall; retain ceramic insulators and mounting hardware.
- After replacement, secure spade connectors fully onto the element studs and re-seat any insulation or retainers to maintain required clearances.
- Restore power and run a short broil test while observing for arcing, unusual odors, or loose mounting; if any abnormal condition appears, cut power immediately and re-inspect connections and mounting.
| Item | Description |
|---|---|
| Connector type | 1/4″ male quick-disconnect spade terminals (insulated or bare depending on model) |
| Typical cold resistance | Roughly 20-50 Ω for 240 V broil elements (varies by wattage) |
| Compatibility | Direct-fit replacement for specified GE range models listed for WB44X173; verify part number against model plate |
During installation, pay attention to mechanical mounting and strain relief: the broil element must sit flat against the rear wall with mounting screws or clips tightened to factory torque so the element does not flex when heated. If the element uses fiberglass or ceramic insulating bushings, ensure they are not cracked and are positioned between the element stud and sheetmetal to prevent shorts; missing insulators are a common cause of arcing and premature failure. After reassembly, perform a continuity and insulation check (element continuity plus no continuity to chassis) before applying full power, then monitor the first broil cycle to confirm even heating and absence of electrical noise or loose terminals, addressing any wiring or mounting issues immediately to maintain safe operation.
Q&A
What is the WB44X173 broil element?
The WB44X173 is an OEM replacement broil element used in many GE-brand electric ranges/ovens. It is the heating element mounted at the top of the oven cavity used for broiling (direct high heat from above). It is a direct-replacement part sold through GE/authorized parts retailers.
What are common symptoms that the WB44X173 broil element is failing or bad?
Common signs include the broil function not producing heat, uneven or weak broiling, visible breaks or blistering on the element surface, blackening or burn marks, or a burning smell coming from the oven. If the element is open (no continuity) it will not heat at all.
How can I test the broil element safely with a multimeter?
First disconnect power to the range at the breaker. Remove the element access screws and pull the element forward enough to access the two terminal connections. With power off, set a multimeter to continuity or low ohms and measure across the two element terminals. A good broil element typically shows a low resistance (commonly around 10-40 ohms depending on wattage; ~20 ohms is typical for a 3000 W 240 V element). Infinite/open reading indicates a broken element. Do not measure for voltage unless you are qualified and take proper electrical safety precautions-voltage across the element when broil is selected should be ~240 V.
How do I replace the WB44X173 element?
Turn off power to the range at the breaker. Open the oven, remove racks, and remove the screws securing the broil element to the oven rear or interior. Pull the element forward, disconnect the two spade terminal connectors (note their orientation), remove the old element, attach the connectors to the new element, position it in place and reinstall the mounting screws. Restore power and test the broil function.Typical replacement takes 15-30 minutes. Wear gloves and ensure power is off while handling wiring.
What voltage and resistance should I expect from this broil element?
The element is intended for a 240 V household oven circuit.When cold, resistance will be low-often in the 10-40 ohm range depending on element wattage (example: ~20 ohms for a ~3000 W element). Voltage measured across the terminals with the broil function selected should be about 240 V.always measure voltage only if you are trained and using proper safety procedures.
After installing a new WB44X173, the broil still doesn’t work-what could be wrong?
If the new element has continuity but still doesn’t heat, check that the oven control is sending voltage to the element when broil is selected (qualified technician only). Possible causes: defective oven control board or broil relay, a bad thermostat/thermal cutoff or high-limit thermostat, poor wire connections, or a tripped safety interlock. Verify correct wiring, fuses/thermal cutouts, and that you have full line voltage to the element.
How do I confirm the WB44X173 is the correct part for my range?
Confirm compatibility by checking your appliance model number (usually on a tag behind the oven door,frame,or storage drawer) and matching it to the WB44X173 part number on GE’s parts website or an authorized parts dealer. Compare mounting bracket style and terminal type (spade connectors) and the element physical dimensions.if unsure, provide your range model number to a GE parts specialist or authorized technician.
Any safety tips or precautions when replacing the broil element?
Always disconnect power at the main breaker before working on the oven.Use insulated tools, avoid touching exposed terminals, and keep the oven cool. If you need to measure live voltage, only do so if you are qualified-240 V is risky. Dispose of the old element properly, and buy OEM or recommended replacements to ensure correct fit and safe operation. If you are uncomfortable with electrical work, hire a licensed appliance technician.
