DG94-00602A Samsung Assembly ELECTRODE;FX710BGS/XAA AC18KV 100 OEM
DG94-00602A Samsung Assembly ELECTRODE;FX710BGS/XAA AC18KV 100 OEM is a factory-designated electrode assembly used in Samsung gas appliance ignition systems. The component is a high-voltage electrode/probe assembly – typically a ceramic-insulated metal electrode with a mounting bracket and electrical connector – designed to present an 18 kV AC ignition potential to a discharge gap. The part designation indicates the OEM assembly and its intended drive voltage (AC18KV), while the remainder of the code (FX710BGS/XAA, 100) identifies model-family and vendor/packing variants.
Inside an appliance the electrode assembly functions as the interface that creates the spark or ionization path required for gas ignition and, in some designs, provides a flame-sensing signal. It is driven by an ignition transformer or ignitor module under control of the appliance electronic control board and operates in close physical and functional proximity to the gas valve, burner ports, and any flame-sensing circuitry.Proper insulation, spacing, and alignment are critical: the electrode must maintain dielectric clearance to surrounding metal parts and present a stable gap to the burner for consistent discharge while withstanding repeated high-voltage pulses and elevated temperatures during operation.
this article will explain the electrode’s electrical and mechanical function, describe model and connector compatibility considerations, and list common failure symptoms such as no spark, intermittent ignition, continuous arcing to chassis, cracked ceramic, and contamination. It will also cover practical troubleshooting methods (visual inspection, verifying control signal timing, measuring transformer output and continuity, and safe isolation of high-voltage components), and replacement considerations including verifying OEM part numbers, mounting orientation, lead routing and insulation clearance, and safety precautions for working around high voltage and gas systems. The guidance is intended for technicians, engineers, and informed appliance owners evaluating, diagnosing, or replacing ignition electrode assemblies.

Function and Role of the Electrode Assembly in the appliance High‑Voltage Ignition System
The DG94-00602A Samsung Assembly ELECTRODE;FX710BGS/XAA AC18KV 100 OEM is the high-voltage electrode module that transfers ignition pulses from the appliance’s ignition transformer to the burner tip. In operation it must present a controlled,well‑insulated conductive path and a precisely positioned tip so the 18 kV pulses consistently arc to the burner ground; variations in tip geometry,gap distance,or insulation integrity change spark location and reduce ignition reliability. The assembly’s ceramic insulation and mounting features are engineered to withstand thermal cycling, chemical exposure, and the voltage stress typical in gas ranges and ovens, and some electrode designs can also be used in flame‑rectification sensing circuits-verify the service manual for model‑specific sensing functions before substitution.
Technicians should match this assembly to the appliance model because physical fit and electrical rating affect both spark behavior and safety; replacing a damaged electrode with an incorrect part can produce weak sparks, sustained arcing, or premature breakdown of insulation. Practical troubleshooting steps include a visual inspection for cracked ceramic or carbon tracking, verifying secure high‑voltage connectors, and confirming the electrode tip gap matches the manufacturer specification (commonly in the low millimeter range). For example, when servicing an FX710BGS range, ensure mounting screw torque and lead routing prevent vibration contact that could create intermittent arcing; if the unit shows no spark, repeated sparking, or flame-loss faults, replace the electrode assembly rather then attempting epoxy or conductive repairs, which do not restore the original electrical properties.
- Key behaviors: generates controlled spark, maintains spark location via tip geometry, and isolates high voltage through ceramic insulation.
- Common failure indicators: no spark, weak/unstable spark, continuous arcing to chassis, visible cracks or carbon tracking on the ceramic.
- Compatibility note: must be replaced with the correct OEM part to preserve voltage rating and mechanical alignment.

How the DG94-00602A Samsung Assembly ELECTRODE;FX710BGS/XAA AC18KV 100 OEM Operates Within the appliance High‑Voltage and Control Circuits
DG94-00602A Samsung Assembly ELECTRODE;FX710BGS/XAA AC18KV 100 OEM functions as the high‑voltage discharge interface in appliances that use a dedicated ignition transformer or inverter. Electrically it presents a controlled gap and insulated path for AC pulses (nominally on the order of 18 kV) so that a spark or ionization current occurs at the intended location; mechanically it provides mounting and a secure HV terminal to the chassis. the electrode’s ceramic/insulator geometry, creepage distances and lead termination determine where breakdown occurs, and those characteristics must match the appliance’s ignition module and control-board sensing scheme for reliable operation.
Within the control circuit the electrode is driven by timed HV pulses under supervision of the appliance control board, which sequences pulses, limits duration, and often monitors ignition via voltage/current or ionization feedback. Common practical considerations include maintaining the specified spark gap and clean insulator surface, routing the high‑voltage lead to avoid tracking, and ensuring the replacement electrode matches the original mounting and terminal type.Technicians typically diagnose electrode issues by observing symptoms such as absent or intermittent sparks,continuous arcing to ground,or ignition-related fault codes; replacing a physically damaged or carbon‑tracked electrode and restoring correct gap and connections typically resolves those faults.
- Operational features: nominal AC 18 kV input, fixed spark gap, insulated chassis mount.
- Checks for troubleshooting: gap measurement, insulator integrity, HV lead continuity and seating.
- Failure modes to watch: carbon tracking, cracked ceramic, loose or corroded terminal.
- Compatibility: must match mounting geometry, terminal style, and rated voltage of the ignition module.

Common Failure Symptoms and Measurable Diagnostic Indicators of Electrode faults
The DG94-00602A samsung Assembly ELECTRODE;FX710BGS/XAA AC18KV 100 OEM is a high-voltage electrode module used to produce an AC high-voltage output for ignition or ionization functions in compatible Samsung equipment. This assembly’s primary role is to deliver a controlled high-voltage pulse while maintaining insulation to the chassis; failures are typically caused by tip erosion, surface contamination (carbon tracking), mechanical damage to ceramic insulators, or moisture ingress. Compatibility with FX710BGS/XAA style mounting and electrical interfaces means a mechanically correct replacement will restore fitment, but electrical integrity must be verified as a matching connector and mounting do not guarantee functional HV performance.
Technically useful diagnostic indicators include measurable open-circuit amplitude, insulation/leakage resistance, continuity of the feed conductor, and the presence or shape of the HV pulse when observed with an appropriate probe. A functioning assembly will present an open-circuit HV pulse near the assembly rating (AC18KV nominal) when driven; significant reduction in pulse amplitude,a distorted waveform on an oscilloscope,measurable leakage current to chassis with a megohmmeter,or visible carbon tracks are clear signs of electrode degradation. Practical checks for technicians: verify continuity of the low-voltage feed, measure insulation resistance between the electrode and chassis, and if available use a high-voltage probe and scope to confirm pulse amplitude and consistency-intermittent sparking paired with decreased HV amplitude usually indicates internal breakdown or surface leakage that necessitates replacement.
- Intermittent or absent spark despite correct drive signal
- Continuous arcing or corona at lower-than-expected voltage
- Visible carbon tracking, charring, or ceramic cracks
- High leakage current on insulation test (megohmmeter)
- Reduced or distorted HV pulse amplitude when measured with a HV probe
| Item | description |
|---|---|
| open-circuit voltage | Nominal output near the assembly rating (AC18KV); persistent drop indicates internal shorting or erosion. |
| Insulation resistance | Measured between electrode and chassis with a megohmmeter; significant reduction (into low MΩ or below) signals surface leakage or moisture. |
| Operational symptom | Intermittent ignition,continuous arcing,or audible HV noise correlate with waveform distortion or leakage on electrical tests. |
Compatibility Matrix, Replacement Considerations and Step‑by‑Step Installation and Verification Procedures
The DG94-00602A Samsung Assembly ELECTRODE;FX710BGS/XAA AC18KV 100 OEM is a high-voltage electrode module engineered to produce and control an AC discharge around 18 kV within the appliance’s ignition/plasma subsystem. Its function is primarily electrical discharge formation and localization: the machined electrode geometry and insulating standoffs determine the spark gap, field shaping and leakage paths, while the connector and mounting interface determine compatibility with specific chassis and harnesses. When assessing replacement options,match the electrode’s nominal AC voltage rating,mounting footprint,connector pinout and insulation creepage distances; deviations in any of these parameters can change spark location,increase carbon tracking risk,or overload upstream transformers and resistors. common failure modes are surface tracking, ceramic or polymer insulator cracking, and corrosion on mating contacts, each of which affects both electrical behavior and safety margins under humid or soiled conditions.
Follow a controlled replacement and verification workflow that eliminates electrical risk, confirms mechanical fit, and validates the discharge characteristics after installation. First, de-energize and discharge high-voltage circuits, then document connector orientation and harness routing before removal. Replace the electrode, torque fasteners to specified values, and restore only the low-voltage control power to run insulation and continuity checks; final verification must include an energized function test observing the spark pattern and listening for abnormal arcing noises. Practical verification steps include measuring low-voltage connector continuity, performing an insulation resistance check at a manufacturer-recommended voltage, and conducting a short-duration operational test under normal load to confirm stable discharge without unintended arcing or heating.
- Power off and lockout/tagout; discharge capacitors and HV components.
- label and photograph wiring; remove old electrode assembly and inspect mounting and insulators.
- Install new electrode ensuring correct gap, seating, and torque; replace any degraded gaskets or standoffs.
- Measure connector continuity and verify low-voltage control signals before applying HV.
- Perform insulation resistance test, then apply HV for a controlled functional spark test while monitoring for leakage, noise, or smoke.

Q&A
What is the DG94-00602A Assembly ELECTRODE and what does “AC18KV” mean?
The DG94-00602A Assembly ELECTRODE is an OEM high‑voltage electrode/ignition assembly sold for certain Samsung appliances (listed as compatible with FX710BGS/XAA in the part description). “AC18KV” indicates the assembly is designed to work with an ignition/high‑voltage circuit that produces on the order of tens of kilovolts (approximately 18 kV) to create the spark needed for ignition. Because it handles high voltage, it includes insulating ceramics and a precisely positioned electrode tip.
How do I know if this part is compatible with my appliance?
Confirm compatibility three ways: 1) match the OEM part number (DG94-00602A) against the part number in your appliance’s service manual or parts list; 2) confirm the appliance model (e.g., FX710BGS/XAA) is listed as compatible by the parts supplier; and 3) compare the physical connector, mounting points and electrical connections to the old electrode. If in doubt,provide your appliance model and serial number to an authorized Samsung parts dealer or service technician.
What are common symptoms that this electrode assembly has failed?
Typical signs include repeated ignition failures or long ignition times, no spark/ignition at all, intermittent ignition, visible arcing in the wrong place, or appliance error codes related to ignition. Smell of unburned gas or frequent lockouts can also indicate ignition components are not functioning and should be addressed instantly for safety.
Can I replace the DG94-00602A myself, and what safety precautions should I take?
Technically a competent DIYer can replace it, but because this is part of a high‑voltage and (often) gas ignition system, follow strict safety steps: disconnect power at the breaker and unplug the appliance, shut off the gas supply if applicable, wait for any capacitors to discharge, and wear appropriate insulated gloves and tools. Do not attempt tests or repairs with power connected. If you are not experienced with high‑voltage or gas systems, use a qualified technician.
How do technicians test whether the electrode assembly is bad?
Technicians usually start with visual inspection for cracks, carbon tracking, or wet/contaminated ceramic.They may check continuity of the low‑voltage wiring to the electrode (with power off) and inspect connectors. Full functional testing of the high‑voltage ignition usually requires the appliance’s diagnostic mode or a proper high‑voltage probe/ignition tester and must be performed by trained personnel because it involves live high voltage. As of safety and the difficulty of isolating igniter failures, many techs replace the electrode assembly when ignition problems are present.
Do I need to adjust the electrode gap or orientation during installation?
Yes – the tip location and gap relative to the burner or target are crucial for reliable spark transfer. Exact gap and placement are model‑specific; always follow the appliance service manual for the correct gap and mounting orientation. If you don’t have the manual, match the physical position of the old electrode exactly. Avoid bending the electrode or changing the tip geometry.
Can I clean or repair the electrode instead of replacing it?
Minor contamination (carbon buildup or grease) can sometimes be gently cleaned with a soft brush and isopropyl alcohol, taking care not to damage the ceramic insulator or bend the tip. However, cracks, heavy carbon tracking, ceramic damage, moisture infiltration, or electrical arcing marks mean the part should be replaced. Because the component deals with high voltage and ignition,replacement with a proper OEM part is recommended when there is any doubt.
Where should I buy an authentic DG94-00602A and does an aftermarket part work?
buy from authorized Samsung parts dealers, reputable appliance parts retailers, or directly from Samsung to ensure you get an OEM DG94-00602A.
