4391996 Whirlpool⣠dryer Flat ignitor is â˘a flat-style hotâ surfaceâ ignitor â˘designed for use in â˘residential Whirlpool gas dryers.â The âcomponent is a thin, âresistive heating element mounted in theâ dryer’sâ burner⣠assembly that, when energized, heats rapidly to âa âtemperature sufficient to ignite⣠the incoming gas; its flat form factor distinguishes it from rod âŁor loop⣠ignitors and affects mounting and connector style.
Inside â˘the âŁappliance the flatâ ignitorâ is part of the gas ignition subsystem and âinterfaces directlyâ with â˘the dryer control â¤circuitry, the gas âvalve, â˘and the dryer’s⤠safety âŁthermostats and thermal cutoffs. The control module supplies current to the ignitor⢠so it glows and creates a combustible âignition â˘source; the gas âvalve⣠opens âonly when the ignition â˘sequence and safety interlocks indicate a correct pre-ignition state. Faults in⣠the ignitor affect heat generation and timing and âcan produce interactionsâ withâ flame sensing or safety devices, so diagnosis â¤typically⤠considers the ignitor together with electrical â˘supply, control signalsand gas flow components.
In this article readers will findâ a technical âoverview of the 4391996 ignitor’s⣠function⣠and typical mounting/connection details, guidance on model⣠compatibility and how toâ identify the correct âŁreplacement,â common failure⢠symptomsâ to⢠recognize (open element,â visible damage, delayed âor no ignitionand⣠abnormal resistance readings)and practical troubleshootingâ and âreplacement considerations. Coverage â˘will emphasize diagnostic â˘checkpoints technicians and⢠educated⤠appliance owners âuse âŁto isolate⤠ignitor âfaults from⤠related failures, best practices for handling âthe fragile heating element and verifying electrical and gasâ subsystem interactions,⤠and factors to consider when selecting and⢠installing a âreplacement part.

Function and Role of⤠the Dryer⣠Flat Ignitor in gas âDryers
The â˘4391996â whirlpool âŁDryer Flat Ignitor âis⣠a ceramic or âŁsilicon-based radiant âignitorâ used⣠as the electrical ignition source inâ many gas âŁdryer burner assemblies.â Whenâ energized by the dryer’sâ control system,â the âignitor rapidly heats to an⢠incandescent temperature⣠and â¤emits âradiant⢠heat that causes the gas/air mixture⤠at the âburner⤠to ignite; the gas⢠valve only opens when the control circuit senses the proper ignitorâ heating cycle.â The âcomponent behaves âŁas â¤a controlled resistance heater rather than âŁa spark device, so its electrical continuity, structural integrity (no visible âcracks)and âcorrect mountingâ and alignment with the burner ports are critical to âŁreliable âignition⤠and safe⤠operation.
- Primary⤠role: provide steadyâ radiant heat to initiate âgas⣠combustion in âthe â¤burner assembly.
- Failure indicators: dryer runs but produces âno heat,extended or â¤repeated ignition attempts,or âthe â¤gas valve⣠clicking without sustained flame.
- Inspection/tests: visual checkâ for cracks, continuity/meter check against manufacturer specand observation of a rapidâ glowâ during â˘aâ controlled test cycle.
- Installation notes: theâ element⣠is fragile⤠andâ should not be touched with bare hands; always âverify part number âŁand wiring compatibility before replacing.
Technicians should verify compatibility with⢠the dryer’s⣠model and wiringâ harness before⤠installing⣠a replacement⢠ignitor âand follow safe service â¤practices such as isolating electrical power and gas supply. If a replacement 4391996 Whirlpool Dryer âFlat Ignitor does not restore heat, proceed⢠to test downstream components (gas valve solenoids, cycling thermostat/thermistor, flame sensor or control board outputs) becuase â¤the ignitor is only one element of⣠the ignition â˘sequence. In practical terms,â replacing⢠the ignitor is frequently enough the correct repair when visible damage⤠or âloss of continuity is present, but âŁsystematic âdiagnosis prevents unnecessary âpartâ swaps âand âensures âthe entire ignition and âsafety â¤chain functions correctly; retain the âoriginal â˘mounting orientation and torque⤠values to â¤preserve airflow and flame geometry.

How⢠the 4391996 Whirlpool Dryer Flat Ignitor Works âInside the Appliance
The 4391996 Whirlpool Dryer Flat Ignitor is a flat, ceramic-based âglow element â˘that âprovides the ignition source âfor the dryer’s burner assembly. âŁMounted across⢠the burner âŁthroat⣠and wired â˘into the dryer’s gas â¤ignition circuit,⣠the part â˘heats â¤resistively when the control board supplies line voltage âduring a heat call. As the â˘element reaches âŁits operating temperature it emits a luminous â˘red-orange glow that allows the gas valve to âopen âand the burner to light; the control system then confirms combustion with the flame sensor or â˘thermostats. The flat â˘ribbon geometry⤠yields an even, exposed â¤hot surface that replaces older rod-style âignitors on many Whirlpool-family gas dryers and provides predictable thermal response and fitment when used âas the âOEM replacement part.
In-service behaviorâ and failure modes â˘are primarily electrical and mechanical: the element âŁtypically fails openâ when theâ ceramic or filament⣠fracturesor it accumulates deposits âthat reduce effective surface area and delay ignition. âŁTypical symptomsâ visible⢠to a â˘technician include no âglow⤠and no heat while the drum⢠tumbles, an âignitorâ that glows briefly but the gas valve never âŁopensor intermittent heating âcaused⤠by a cracked âelement⣠that âmakes intermittent contact. Troubleshootingâ steps âŁinclude âa cold continuity/resistance⤠check across âthe ignitor terminals (expect a low,tens-of-ohms reading),verifying ~120 VAC present at the harness â¤during âthe start-of-cycle heat call,and âŁvisual inspection âŁfor cracks⢠or darkened hot⢠spots.â If the ignitor shows no continuity orâ visible damage,⤠replacing it with the correct 4391996â Whirlpool Dryer Flat Ignitor restores the intended thermal profile and fit; if the ignitor glows but the burner still won’t light, âtest the gas valve âcoils and flame-sensing circuit â˘next.
- Role: âprovides the hot surface required⣠to ignite âburner â˘gas during the start-of-cycle heat call.
- expected electrical behavior: low cold resistance â(tens âŁof ohms)⢠andâ line-voltage appliedâ only â¤duringâ the ignition âinterval.
- Common failures: open filament, ceramic fracture,⣠or heavy soot buildupâ causing ignition delay.
- Practical tip: always verifyâ harness⢠voltage and continuity before âŁreplacing⣠other components; handle theâ flat element â˘carefully-ceramic is fragile.

Common Failure âSymptoms, Measurement âŁCriteriaand Typical Failure âŁModes
The 4391996 âWhirlpool Dryer Flatâ Ignitor is a resistive ceramic-basedâ ignition element designed âto produce the high surface⣠temperature required to light the âŁdryer’s gas burner when the control calls for âheat. âIt functions as the primary ignition⢠source in âŁflat-style âŁignitor assemblies, heating rapidly whenâ line â¤voltage âis applied and allowing the gas valve âto âopenâ and âŁsustain combustion. Compatibility is determined by theâ ignitor’s âŁmounting style, leadâ length, â˘and connector type rather than by function âalone, so confirm the part number andâ plug configuration against the dryer’s⢠service⢠sheet beforeâ replacement.⤠Practically, âthis component is passive and âsubject to mechanical âand thermal stress-its failure modes âare usually detectable âŁby visual inspection andâ electrical measurement rather than intermittent control âfaults.
- No heat at all whenâ the dryer cycles (ignitor âfails to glow).
- Repeated starter attempts: âcontrol clicks and retries âto ignite,â or the gas valve opens briefly then shuts⣠off.
- visible âŁdamage: â¤crackedâ ceramic, broken leadsor âspalled/glazed element surface.
- electrical âcheck: infinite resistance or no continuity⤠across the⤠ignitor leads indicates an open⢠circuit; aâ measurable âlow-ohm resistance indicates continuity âbutâ does not guarantee sufficient heating under load.

Q&A
What⢠is the 4391996â Whirlpool Dryer Flat Ignitor âŁand⤠what â¤does it do?
The 4391996 is an OEM flat ceramic â¤glow ignitor used in many âWhirlpool/Maytag/Kenmore âŁgasâ dryers.â It heats to a⢠high temperature when the â˘dryer calls for⢠heat; âthe hot glow âignitesâ the gas from⤠the â¤burner assembly so âthe âdryer⢠can produce heat. It isâ indeed a âreplacement partâ for the glow-type ignition â˘system (not a spark â˘igniter).
How can âI tell âŁif the 4391996 ignitor is⤠bad?
Common signs⢠of⣠a failing ignitor are: the dryer âtumbles âŁbut producesâ no heat, âŁthe⤠ignitor âŁis visibly cracked or brokenor theâ ignitor âdoes not glow whenâ a heatâ cycle starts. You can verify electrically by unplugging â˘the dryer,â removing the ignitor and checking it with a multimeter âŁfor continuity; â˘an openâ circuit (no continuity) means the element is failed. Also observe the ignitor âduring âŁa start cycle-if it âŁdoes not glow⢠but â˘the thermal fuse and âthermostats are intact, the ignitor is suspect. Never⣠touch the ignitor surface and⢠always âcut power and gas⢠before inspections.
How do âŁI test the 4391996 âignitor with a multimeter safely?
Safety âŁfirst:â disconnect both electrical power and gas⣠to the dryer. Remove theâ access panel to⣠reach the ignitor and disconnect its â˘electrical connector.⤠Set the âmultimeter âŁto the â¤continuity âŁor low-ohm â¤setting and measure across⣠the ignitor terminals. A âfunctioning ignitorâ will âŁshow a measurable resistance (continuity); an âopenâ (infinite) reading indicates the element is broken and needs replacement.⣠If you’re âunsure of readings, compare toâ the service⣠manual or â¤consult a technician. â¤Do not attemptâ a live-voltage bench â˘testâ unless âqualified.
What other components should I checkâ if â¤the ignitor⤠is good âbut the dryer âstill won’t heat?
If the ignitor tests good but there’s noâ heat, â¤check the âthermal fuse,⣠high-limit thermostat,â cycling â˘thermostat/thermistor, gas valve coils/solenoids, flame sensor/thermocouple, the doorâ switch and âthe timer or electronic⤠control. A failed thermal⣠fuse⣠(common) or â˘bad gas âvalve solenoids can prevent âignition even with a working ignitor. Follow the dryer’s wiring⤠diagram and safety âprocedures while â˘testing.
Is â¤replacing âthe 4391996 ignitor a difficult job and⤠how â˘do I replaceâ it?
Difficulty â¤depends on the dryer â¤model but âmost replacements are moderate in difficulty⤠and can beâ done with basic tools. âSteps in âgeneral:⢠disconnect power and gas, â¤remove the⤠dryer access panel (front âŁor rear/top⣠depending⢠on model), locate and disconnect the ignitorâ wiring,â remove the mounting screws and⢠carefullyâ remove the â¤old ignitor (handle by⣠the metal bracket; do not â˘touch the ceramic element),â install the new â¤ignitor,⤠reconnect wiring, reassemble and ârestore power and gas. Alwaysâ follow the service⤠instructions â¤for your specific model and observe â˘safety precautions for gas appliances.
can I clean âor⢠repair a cracked 4391996 ignitor instead⣠of â˘replacing it?
No. The â˘ceramic heating element is vrey fragile and cannot âbe reliablyâ repaired or cleaned to restore function.any visible cracks⤠or breaks meanâ the element has⢠failed and the ignitor should be replaced. Attempting âto âreuse a damaged ignitor is âunsafeâ and will âŁresultâ in continued failure to ignite.
How âdo â¤I know if the 4391996 is the correct â¤replacement for my dryer?
Confirm fitment⢠by checking â˘your dryer’s model⤠number against the part compatibility list on the parts â¤supplier or Whirlpool parts site. The 4391996 is â¤used in many Whirlpool, Maytag and Kenmore gas âdryers, but not âevery âmodel uses a flat âignitor.Compare âthe old ignitor’s shape, mountingâ holesâ and terminal⢠styleâ with the replacement and â¤verify part numbersâ before purchase.
Are⤠there any âsafety warningsâ I should know when working with the 4391996 ignitor?
Yes-alwaysâ disconnect⣠electrical⤠power âŁand⢠shut⢠off⣠the â¤gas supply before servicing the dryer.â The⢠ignitor gets very hot during operation; âŁallow it âto cool before handling. â¤Avoid âŁtouching the ceramic surface (oils⣠from skin can damage the element)and ensure all gas â¤connections are⤠tight and checked âŁfor leaks whenâ reassembling. â˘If you’re not âcozy working with gas appliances âor âelectrical components, hire a qualified technician.
