The 134011703 Frigidaire Dryer Timer⣠Knob is a front-panel control knob designed to mount â˘onto the timer or selector shaft of â¤compatible Frigidaire clothes dryers. As a user-interface mechanical component, it âprovides the physical connection âbetween the operator’s rotational input and the dryer’s internal timer or selector switch, typically usingâ a splined or D-shaped bore, index markingsand detents for tactile feedback.
Within the appliance the⤠knob mechanically couples to the timer/control shaft and⤠thereby changes the position ofâ the timer’s⤠cam â¤and switch bank, which in turn alters electrical pathways that control the âŁdryer motor, heating elementsand auxiliary circuits. It thus interacts â¤primarily with the mechanical⣠timer assembly and indirectlyâ withâ the electrical controlâ systemand âŁits fit, spline profile, insertion depth and detent condition areâ critically important⢠technical details as âwear or incorrect fit can produce mis-selection, intermittent contactorâ a âcomplete inability to â¤actuateâ the timer.
In this article you will find a technical overview of the⢠knob’s function, guidance for verifying compatibility with specific âŁdryer models, common failure symptoms âand how to distinguish knob faults from âinternal timer or switch failures, practical troubleshooting checks (visual âŁinspection, shaft dimensioningand switch continuity tests)and replacement considerations such as matching spline type, mounting hardwareand â¤post-installation verification procedures. The intent⤠is to provide technicians, engineersand experienced appliance ownersâ with the information needed toâ diagnose control-interface issues and â˘perform a correct, reliable replacement when required.

Function and Role of âthe Dryer⤠Timer Knob âin Cycle selection and Mechanical Control
The 134011703 Frigidaire dryer Timer Knob serves âas the â¤mechanical user interface that selects cycles and indexes the dryer’sâ internalâ timer assembly. Rotating theâ knob transmits torque through the plastic hub into the timer shaft and cam stack, producing discrete detents that align specific switch cams or contact⣠wafers to â¤the selected program. Becauseâ the knobâ is a mechanical coupling â¤rather than an electrical component, compatibility depends on matching the knob’s spline pattern, âhub diameterand retaining method⤠to the dryer’s⢠timer shaft; an incorrectlyâ matched knobâ can slip on the âshaft or apply lateral force that distorts the timer cam. âIn practical use,â settingâ a âtimed cycle moves âthe cam to successive contact positions to run the heater â¤and motor for the chosen interval,⤠while selecting âŁan automatic â¤moisture â˘cycle positions the cam to enable sensor circuits and different timed intervals as dictated âby the â˘timer mechanism.
The knob’s expected⤠behavior is positive detent indexing and â˘firm engagement with the timer shaft; â¤wear or damage typically â˘manifests as free-spinning, intermittent contactor a mismatch between knob position and actual cycle. Technicians can verify mechanical function by removing the knob to inspect the spline⢠for stripped âŁteeth and by rotating the exposed shaft to feel cam detents or to exercise the timer contacts with a multimeter. Replacing the part with a â˘correct match restores mechanical⤠indexing – using a non-compatible replacement risks premature failure of the hub or the timer cam. Common practical indicators and features toâ check include:
- spline pattern and hub fit (ensures no axial play)
- Number and firmness of detents (corresponds to selectable⣠cycle positions)
- Retention style (clip, nutor push-fit) and presence of a locking feature
- Visible wear such as cracked plastic or âdeformed teeth causing slip

How the 134011703 Frigidaire Dryer Timer Knob Interfaces âŁwith theâ Timer Motor, âSwitchesand Control Circuitry
Theâ 134011703 Frigidaire Dryer Timer âKnob is a passive user⢠interface that⣠mechanically⣠couples to the timer spindle throughâ a specific spline âand depth profile; turning the knob sets the timer rotor position and, on some models, engages a start detent or push-to-start⣠mechanism. As the knob establishes discrete indexed positions, correct fitment is required to align the indicator⢠with âthe timer cams and detents; an incorrect or loose replacement can offset cam timing or prevent the timer⣠motor â˘from⣠advancing. The knob itself âcontains no electronics,â but its mechanical engagementâ dictates which cam profiles and switch âwafers the rotor exposes to the control circuitry.
The timer motor⣠is typically â˘a synchronous or step-type motor thatâ rotates the timer rotor at a controlled rate while cam lobes beneath the rotor open and close âŁswitch contacts to route mains power to the drive motor,â heating element, âor accessory sensors. Misalignment between⤠the knob and rotor will change â˘when those⤠cam-actuated switches close,â producing symptoms suchâ as failure to start, continuous heatingor premature cycle termination. For troubleshooting and installation, confirm spline type and⤠seating depth, verify the⢠knob provides positive detent feedbackand observe which circuits are energized in each⣠selected position to ensure correct interaction with the timer motor and control switches.
- Common symptoms: knobâ spins freelyâ (no advance), âŁwrong cycle behavior (heat on continuously), â˘or no startâ when turned.
- Installation checks:⤠spline match,full seating,and âŁcorrect rotational index alignment.
- Behavior note: knob sets position only; switching behavior is âproduced by the underlying timer cams and motor.

Common failure Symptoms, Visualâ Indicatorsand Measurable Electrical Faults of theâ Timer Knob
The⤠134011703 Frigidaire â¤Dryer Timer Knob functions as âthe âmechanical interface between âŁtheâ user and the dryer’s â¤rotary timer shaft. It âis a molded spline-and-detent actuator that must match the timerâ shaft profile and detent geometry to accurately select âcycles; an otherwise compatible knob will transfer torque⣠and position feedback to⤠the timerâ without âintroducing play. âTechnicians â˘should verify spline âfitâ and detent engagement for the specific Frigidaire model before replacing the knob, because a worn or incorrect knob can âmimic⣠timer faults by failing to⤠hold a selected position even though the internal â¤switch and motor are electricallyâ sound.
Common failure indications include physical wear, âheat damageand symptoms that point toâ either⤠a mechanical actuator⣠problem or an âunderlying⤠electrical fault in the timer assembly. Visual indicators such as rounded or missing spline teeth, radial cracks, â˘or melted plastic around the hub generally indicate mechanical failure; these should be inspected with the power disconnected⤠and the knob removed. Measurable electrical⤠faults are assessed at the timer switch terminals: use a multimeter âto check for continuity in âexpected positions (closed circuit where contacts âshould be made, open circuit where they should âŁbe isolated). If the knob slips butâ continuity tests show correct contact patterns,replace⢠the knob; if contacts are intermittent or burned,the timer switch or cam⢠assemblyâ is likely the failing component rather than the knob itself.
- Knob spins freely â¤on the shaft – stripped spline or wrong part⤠fit.
- Selector does â¤not stayâ in a detent – worn detent âmechanism or broken internal cam.
- Burned/melted plastic ânear hub – localized overheating or proximity to a hot component.
- Machine cycles incorrectly despite correct knob position – intermittent or open contacts in the timer switch.
| Item | Description |
|---|---|
| Visual check | Inspect spline teeth, hub âcracks, discoloration from heat; confirm physical engagement with the timer shaft. |
| Mechanical test | With knob removed, check for axial/play and⤠detent feel âon the timer shaft; excessive play indicates âa worn⢠knob or shaft. |
| Electricalâ check | Measure continuity between timer terminals across cycle positions: closed where contacts should connect, open where isolated; intermittent readings or carbonized â¤terminals indicate timer replacement. |
Replacement Considerations and StepâbyâStep Installation Procedures âfor theâ Dryer Timer Knob
The 134011703 Frigidaire Dryer Timer Knob âŁisâ a user⣠interface component that engages⤠the timer shaft to select drying cycles and durations.â It does not contain active electronics; instead it provides a mechanical interface-typically a splined or D-shaped bore-that mustâ match âthe timer shaft pattern â˘and keyway on the dryer. When replacing this âŁpart, confirm the âshaft profile,â presence of any retaining clip or set screwand the orientation of the index marker so the⤠knob will correctly register positions and detents. Compatibility is determined by the physical fit and the knob’s ability âto seat fully âŁon the shaft:â a correct replacement will provide positive detent feedback and consistent rotation torque without binding or excessive play.
Disconnect power to the appliance before âbeginning work. âŁTo replace âthe knob, remove any retaining hardware on the old knob (set screw or clip) and pull straight off the shaft; if a set screw is present, back it out first. Cleanâ the shaft of debris and â˘inspect for gouges or worn splines that would prevent a secure fit.⢠Align the âreplacement knob’s keyway â¤with the shaft, push it fully into⤠position or tighten the set screw to light torqueand verify âthe timer advances and detents correspond to the control panel âmarkings. If rotation feels loose or the timer⣠does not advance, recheck fitment â˘and replace the timer shaft assembly if necessary rather than forcingâ a loose-fitting knob.
- remove retaining âŁclip âor loosen âset screw (if present).
- Pull old knob straight off; inspect shaft for wearâ or damage.
- Align new knob keyway â˘with shaft, push until seated or secure set screw.
- Restore power and confirm full range of timer positions and detents.

Q&A
What exactly is the 134011703 Frigidaire dryer⤠timer knob?
The 134011703 is a replacement control knob designed to⢠fit the timer/control⤠shaft on certain Frigidaire dryers.It âis âŁthe user interface pieceâ you turn to set the dryer cycle and typically âmounts âonto the âtimer shaft (splined or keyed). It is a cosmetic and mechanical control part,not theâ timer⤠motor or â˘internal switch assembly.
How do I âknow if 134011703 is the correct part for my dryer?
Confirm compatibility by checking your dryer’s model number (usually on a âtag inside the door opening⣠or on⢠the back). Crossâreference that model number with the⢠Frigidaire parts list or a reputable parts supplier. The replacement knob⣠must âmatch âthe timer shaft type (spline count/shape) and mounting method-if in doubt, compare the old knob’s part number or⢠the shaft shape to photos/specs before ordering.
Can I fix a nonâadvancing timer âŁby replacing the â˘knob?
No.A loose,â crackedor missing knob can make the timer hard toâ set, but if theâ timer does not advance during the cycle or cycles â˘incorrectly, the problem is with the â¤timer motor or internal switch,â not the knob.⤠Replacing the knob only restores⣠the âuser control; diagnose the timer motor/switch assembly (and checkâ power/safety interlocks) if the timer itselfâ fails.
How do I remove and install the 134011703 knob?
Always disconnect power before working on the dryer. Most timer knobs areâ pushâon styles: pull the old â¤knob straight offâ the splined shaft. Some knobs use a small set screw or retaining clip-inspect the⣠back of the knob for âa â˘screw and loosen it if present. To install, align⣠the knob with the âŁshaftâ splines or keyway and press straight on until seated; tighten any set âscrew if applicable. Don’tâ force it-if it won’t âseat, doubleâcheck alignment and spline type.
Does âthe 134011703 knob have electrical parts I need to test with a multimeter?
generally no.The knob itself is a passive mechanical part and â¤contains no wiring or electrical components. If youâ need to test the timer function, you must access the⣠timer âŁswitch terminals and check continuity or operation with a multimeter while following safe diagnostic procedures and with power removed when â˘connecting probes. Ifâ you’re not comfortable, consult a qualified technician.
My knob is loose or⤠spins without engaging the timer-what should I check?
First check⢠whether âŁthe knob has slipped on⤠the shaftâ (improper seating) or if a set âŁscrew has loosened. If the knob is properly seated but still spins âindependently, the internal splines of the knob may be stripped or the timer shaft could be damaged.Replaceâ the knob âif it’s stripped; if the shaft is damaged, the timer/control assembly may need replacement.
Where can I buy an authentic 134011703 replacement and are aftermarket knobs⣠acceptable?
You can purchase theâ OEM 134011703 from Frigidaire authorized parts dealers, appliance parts stores, âŁor reputable online âŁretailers. Aftermarket knobs are often cheaper and âcan âbe acceptable if they match the spline âtype, dimensionsand labeling. For best fit and finish, choose OEM or a highâquality aftermarket part that lists âcompatibility with âŁyour dryer model.
Are⢠there âany safety tips I⤠should â˘follow when replacing the knob?
Yes: disconnect power to the dryer before handling⤠controls (unplug â¤electric dryers or switch off the circuit breaker;⣠for gas dryers â˘also shut off the gas if you will access internal components). Avoid forcing parts-misalignment âcan break splines. âŁIf you must remove control panels to access the timer,⤠keep track of screws and wiring and follow manufacturerâ instructions. If you are⣠unsure about electrical or âgas components, hire a certified appliance technician.
