134011703 Frigidaire Dryer Timer âKnob is a user-interface⣠rotary control designed to⤠mateâ with the dryer’s â¤timer or control shaft andâ allow the operator âto select drying cycles and timing positions.â As â¤a replacement controlâ knob, it provides mechanical engagement with the timer shaftâ (typically via splines or a â˘keyed bore) and âa âŁvisible pointer orâ index to show the selectedâ setting; it âis a passive mechanicalâ componentâ that translates â˘human input into a distinct shaft position on the âcontrol mechanism.
Inside the appliance, the knob interfaces directly withâ the timer â˘or control assembly and thereby affects the sequencing of the dryer’s âelectrical circuits-most commonly those that â¤power the drive⣠motor, heating elementand any âtimed or sensoryâ inputs. While⣠the knob itself â˘contains no active electronics,â its⣠fit and alignment are critically âimportant as incorrect seating or damaged splines can produce missed or incorrect timer positions, leading â˘toâ improper⢠cycle selection. Technically-minded⤠readers should note âthe â¤importance of spline count, boreâ diameter, detent engagement and retention⣠features, as these determine mechanical compatibility and âreliable â¤tactile indexing âwith âthe⢠underlying timer âmechanism.
In theâ article that follows⢠you will find a âtechnical examination of the 134011703⢠knob’s function andâ typical applications, guidance on how to⣠verify âcompatibility with specific Frigidaire dryer models (including âhow to check âshaft type and part numbers), common⤠failureâ symptoms to watch for⣠(slippage, broken splines, loss of indexing), practical troubleshooting steps⢠to â˘isolate knob versus âŁtimer failuresand considerations⣠for safe and proper replacement⢠including basic installation checks to confirm correct seating⣠and operation.

Functional âRole and ElectricalâMechanical Interface of the Dryer⢠timer Knob
The 134011703â Frigidaire Dryerâ Timer âŁKnob is the user interface âcomponent that transmits rotational input âto⤠the dryer’s⢠timing mechanism or selector switch. Mechanically it â¤fits onto the timer shaft (commonly⣠a splined âŁor D-shaped shaft on Frigidaire âmodels) âand provides indexing âandâ tactile detents so the selected cycle corresponds to aâ discrete internal cam position or electronic encoder state. In practical terms,the knob does not contain electrical components; ârather it must maintain positive mechanical engagement with the timer shaft so that â˘a chosen position results in the intended switching sequence inside the timer assembly. â¤Confirming shaft profile, spline âcount,⤠and whether the knob is a push-on or screw-mounted type is necessary âto ensure correct fit and reliable operation.
The knob-to-timer interface is critical for correct electrical sequencing because the timer’s internal cams⤠or⢠switches change âcircuit paths as âthe shaftâ rotates. A âŁloose or âstripped knob will produce symptoms⢠such â¤as⢠slipping â¤between marked positions, intermittentâ engagement of heat or motor â˘circuits, â˘or incorrectâ cycle selection. Technicians should inspect the⢠knob â¤spline⣠for wear, verify âŁalignment of the⤠pointer â¤to the timer indexand during diagnosis⤠rotate the knobâ while monitoring switch continuityâ or â¤observingâ the timer motorâ to confirm each detent corresponds to the â¤expected electricalâ state. Below isâ a concise listâ of practical features and checks followed by a speedy technical referenceâ table toâ aidâ compatibility assessment.
- Mounting: push-fitâ orâ threaded â˘onto splined/D-shaped timer shafts; confirm âbefore replacement.
- Detents/indexing: âprovides⢠discrete â˘stop points that⢠correspond âŁto âinternal switchâ positions.
- Material and wear:â plastic splines âŁcommonlyâ wear over time and cause⤠slipâ under load.
- Diagnostic use: rotate knob while â˘measuring continuity to map mechanical positions to electricalâ contacts.

How the 134011703 Frigidaire⣠Dryer Timer Knob Operates Within the Dryer Control Assembly
The 134011703 Frigidaireâ Dryer timer âKnob is the user-level actuator that âmechanically⢠couples to the dryer’s timer/control shaft and âtranslates a⢠manual rotation into discrete⢠timer positions. When turned, the âknob rotates âŁthe internal rotary timer or cam stack inside the controlâ assembly, which⣠sequentially⣠opens âŁand closes contact⣠setsâ on the switch âpack to route powerâ toâ the motor, heating circuitand other control circuits. The knob’s hubâ is designed to⣠match the control shaftâ profile – typically a âkeyed or splined interface âŁ- so torque is transferred reliably and â¤position âŁindexing is maintained relative to the printed cycle⣠markings on the⣠console.
- Detentedâ positions that âŁindex the timer cams to definedâ cycle â¤stages.
- Spline or keyed hub for mechanical âengagement and torque transfer.
- Retention feature (clip âorâ collar) to hold the knob on the shaft without axial play.
- Pointer alignment for accurate â¤selection of timed âor automatic âcycles.
In service, the knob’s behavior gives clear diagnostic clues: a knob âthat rotates without influencingâ the timer usually âindicates a stripped hub, worn splinesor⣠a failed retention⣠feature, whereas â˘incorrect⤠cycle selection with normal tactile feel suggests internal âŁtimer wearâ or misaligned cam indexing. Technicians commonly verify mechanical engagement⤠first, then check continuity across âthe switch⢠contacts while â¤advancing the control⤠to confirm the timer’s electrical output. Replacing the â¤external knob⢠typically restores user controlâ when hub damage is isolatedâ to the âplasticâ part; if contactâ switching remains incorrect, the entire timer/control⢠assembly requires âŁinspection or replacement.

|---|---|
| Shaft interface | Splined or keyed hub designed to match â˘the dryer control shaft âfor secure torque transfer |
| Primaryâ function | Rotate the timer/cam stack to open/close specific contact setsâ and⣠select cycles |
| Common⢠failure modes | Worn/stripped splines, cracked⣠hub, loss of detents or retention âŁclip |
Common Failure âModes and âObservable Symptoms⢠of a faulty Timer Knob
The 134011703 âFrigidaireâ Dryer Timer⢠Knob is the user interface component âthat âŁtransmits ârotational inputs âtoâ the dryer’s â˘timer âshaft⤠through a molded spline and detent arrangement.â Its primary function is mechanical: it locates the selector position, provides tactile detents for cycle selection,⢠and â˘maintains correct alignment of the indicator âwith the timer scale. Compatibility depends on matching the knob’s internal spline profile, boss depthand face orientationâ to the âdryer’s timer âshaft; an incorrect profile will produce slip or eccentric⢠mounting â˘andâ can â¤damage the timer shaftâ or âprevent proper selection of timed cycles.
- Freeâ spinning: The knob rotates without turning â˘the timer shaft, âindicating a⣠stripped internal âspline or fractured hub.
- Wobble or looseness: excess axial play or off-center rotation caused by â˘a worn friction âfitâ or cracked mountingâ boss.
- Loss of detents/clicks: â Smooth rotation where discrete steps⤠are expected, often from worn detent ribs or broken spring features in the knob.
- Indicator misalignment: Pointer âŁdoesâ not match the timer scale when a cycle is selected, signaling incorrect â˘part⣠orientation âor incorrect replacement âŁgeometry.
- Intermittentâ engagement: âKnob occasionally engages then slips, consistent⤠withâ partialâ spline wear or heat-deformed plastic.
- No change in⤠cycle despite⣠turning: If the knob moves theâ shaft but âthe dryer does not advance, fault is⣠more likelyâ in the timer mechanism;⢠if the âshaft does not move,⤠the knob is the probable cause.
To distinguish knob faults âfrom internal timer failures, â¤inspectâ the⢠knob for visible cracks,â melted deformationor stripped splines and âverify whether rotation of â¤the knob produces⣠corresponding rotation of⢠the metal⢠timer shaft. A âquick⤠bench check-removing the knob and observing shaft movement while operating the âŁselector-helpsâ confirm âŁwhether â¤replacement of the knob alone will restore function. When replacing, chooseâ a âknob that matches the â¤shaft profile and mounting dimensions to avoid ârepeat âfailures or⣠induced damage âŁto âtheâ timerâ control.
| Item | Description |
|---|---|
| Shaft profile | Match spline count/shape â¤andâ boss âŁdepth⢠to âensure positive â˘engagement. |
| Typical symptom | Free spinning or wobble âindicates mechanical wear of the knob hub. |
| Diagnostic action | Remove knob, observe shaft rotation; replace knob only â˘if shaft rotates correctly with no⤠internal âbinding. |
Model Compatibility, âReplacement Procedures and Diagnostic Troubleshooting for the Timer Knob
The â˘134011703 Frigidaireâ Dryer Timer âKnob is the user interface component that mechanically couples the control shaft to the timer âswitchâ assembly; it transfers rotational⢠input andâ provides⣠an index⢠for selectedâ cycles. Functionally, the knob must match âthe shaft â¤profile (splined, D-shaftor keyed) and the spline count âand diameter determine secure engagement and torque transmission. âTechnicians should verify the shaft profile and measure spline geometry beforeâ ordering replacement âŁparts, since a mismatched â¤knob will either slip under load âor fail to engage the timer contacts properly. A âŁcorrectlyâ fitted knob will rotate the timer cam without excessive play and will align its pointer with the control panel detents to accurately select dryingâ programs.
Replacement and troubleshootingâ require basic mechanical and electrical checks performed with⢠the dryer powered⣠off.â Begin by pulling the knob straight off the shaft â(or loosening the set screw/retaining clip if present)â and inspect⣠for â˘rounded or missing âspline⢠teeth, cracked âplasticand internal deformation from heat. Use a â¤multimeterâ to check continuity through the timer mechanism if rotating the âshaft does not change the drying function; if the knob rotates but the timer contacts do not actuate, âthe failure⣠is likely in the timer switch rather thanâ the knob. For practical verification,a⤠knob⣠that freely rotates â¤withoutâ moving the shaft indicatesâ a worn spline interface,whereas aâ knob that binds â¤or shatters when applied often signals a misfit or incorrect part selection. Replace the knob with the identical spline profile and confirmâ engagement â¤by rotating through all detents whileâ observing timer cam movement.
- Symptom: Knob spins withoutâ advancing timer – Likely⢠cause: stripped spline or incorrect shaft âprofile.
- Symptom: â¤Knob â¤is loose/wobbly⢠– Likelyâ cause: worn inner hub⢠or oversized⢠bore.
- Symptom: Knob â˘binds or cracks during installation⤠– Likely cause: wrong part or interference on control shaft.
- Symptom: Timer not changing âsettings despite knobâ movement – Likely cause: timer switch failure; verify continuity.

Q&A
What is the 134011703 âŁFrigidaire dryer timer knob and âwhat does it do?
Part 134011703â is⣠the user-control knob that â˘fits onto the timer orâ selector shaft of many Frigidaire dryers. It provides the interface âfor selecting drying cycles and timer⣠positions;⤠the knob itself does not â¤contain electronics – it⢠simply engages âthe timerâ shaft toâ move⣠the internal timer switch or⤠indicate the selected setting.
How can Iâ tell⣠if I only needâ to replace the knob orâ the entire timer assembly?
If the knob is cracked, missingor âthe plastic splines⤠are worn, replacing the knob⢠alone âwill âusually fix âŁthe⣠problem. If the knob spins freely on the shaft, âŁcheck the plastic splines on the knob and the metal/plastic âsplines on the timer shaft – a stripped spline on either side⢠means replacement of that part is âŁrequired. If the timer does not advance âor the dryer doesn’t respond âto knob positions even afterâ aâ good knob is fitted, the⤠internal timer mechanism or timer motor is likely faulty and the whole timer/control⣠assembly will need replacement.
How do I remove⤠and install the 134011703â knob?
Always disconnect power to the dryer âbefore working on controls.Most knobs removeâ by pulling straight âŁoff âŁthe timerâ shaft; some may have a small retaining clip or set screw-inspect the base of the knob. To install, align⤠the knob âsplines with the timer shaftâ splines and push firmly until it seats. If there is a set screw, tightenâ it snugly. No special tools â˘are usually required, though a flat screwdriver can help release a clip if present.
Is⤠134011703 compatible with my⤠Frigidaire dryer â¤model?
Compatibility varies by model âŁand year. Confirm fit by checking the dryer’s model number (on âŁthe dryer’s tag) against the part number in the manufacturer parts diagram âorâ a trusted parts retailer. Also âcompare the spline pattern and knob diameterâ to your existing knob; if theâ part number is printed on your old knob, match it exactly.
My knob is⢠intact but the dryer â˘won’t start or the timer won’t advance. Could the knob beâ the problem?
If the⤠knob turns normally â¤but the dryer won’t start or the timer doesn’t advance,â the problem isâ usually internal (timer motor, start switch, door switch, motor, thermal âfuseor wiring) rather than the knob. Use a multimeter to⤠check â¤continuity on the start switch⢠and thermal fuse and verify the timer motor is getting power. Replacing the knob alone will⣠not fix internal electrical failures.
Do I need a technician to replace the â˘134011703 â˘knoband⤠how⢠long⣠does âŁitâ take?
replacing the knob is typically â¤a straightforward DIY taskâ that takes 5-15 minutes âŁfor someone pleasant with basic applianceâ work. Always â¤disconnect power first. If⣠you âneed to⣠access the âŁtimer/control assemblyor if you suspect internal electrical faults,⣠a trained technician is recommended.
Where can I âŁbuy a genuine⤠134011703â knoband are aftermarket âknobs⤠acceptable?
The knob â¤is available fromâ Frigidaire-authorized⣠parts dealers, major appliance parts websitesand some appliance repairâ shops. OEM (genuine Frigidaire) parts are recommended forâ an exact⤠fit⤠and color match. Quality aftermarket⢠knobsâ can âŁbe acceptable and are⣠often less expensive, but verify spline pattern,⢠diameter, âand color before buying.
Any safety or installation tips I should follow when âŁreplacing the knob?
Disconnect the âdryer from âŁpower (unplug or turnâ off circuit breaker) before removing theâ knob. Handle the control gentlyâ to avoid⤠damaging the âtimer⢠shaft. If âyou must remove the control panel âor replace theâ entire timer assembly, keep track of screws and wiring, âand take a photo of the wiring before disconnecting â¤to ensure correct reassembly. If you are unsure âabout electrical troubleshootingâ or âreplacing internal parts, hire⣠a qualified appliance technician.
