134011703 Frigidaire Dryer Timer Knob is a user-interface rotary control designed to mount onâ the front control panel adn engage âŁthe dryer’s timer or âselector shaft. As a⤠mechanical interface component,⢠the knob transmits user input-cycle selection and timing positions-to â˘the underlying timer mechanism or electronic control encoder through a splined or D-shaped shaft coupling and a retaining device.It is a small but critical part used on a rangeâ of Frigidaire dryers to provide positive tactile selection of programme positions and to secure correct alignment between the operator âand the control assembly.
Inside the appliance, the timer knob interacts directly with the timer/selector assembly and indirectly with the dryer’s control systems, âincluding the timer motor âor â¤encoder, switching contacts or ârelaysand the heating and motor control circuits. Turning the knobâ positions cams or communicates position data that âŁcause the timer to advance⢠and engage the âappropriate thermostats,⤠heating elementsand motorâ circuits for aâ chosen cycle. A correctly fitted knob ensures reliableâ mechanical engagement and repeatable position indexing; a⤠damaged or mismatched knob can cause improper selection, intermittent âŁcontactor failure⤠to actuate safety interlocksâ and sequence logic.
In âthis article readers will â˘learn how the 134011703 knob functionsâ as part of theâ control interface,⤠which dryer models and shaft types it is compatible⤠with, common failure symptoms â(such as stripped splines, slipping, cracked⤠plasticor loss of indexing)and systematic troubleshootingâ steps to confirm whether âthe knob or the underlying timer⢠is at fault. The guide will also cover practical â˘replacement considerations-shaft profile matching, retaining hardware,⢠panel fitmentand⣠basic safety precautions such as disconnecting power before⤠inspection-so technicians, engineersandâ appliance owners can make informed repair decisions without assuming needless risk.

Function and Role of the⢠Dryer Timer Knob within Frigidaireâ Control Systems
The 134011703 Frigidaire Dryer âTimer Knob is a âŁmechanical userâ interface â˘that provides tactile, indexed control of⢠the dryer’s timing mechanism. âŁMechanically, the knob couples⢠to â¤the timer shaft-typically a splined or D-shaped shaft-and translates âŁrotational input into discrete timer positions that âactuate cams â˘or âswitches inside the control assembly. Each detent on âthe knob corresponds to a timer contact configuration that enablesâ or disables the âmotor, heater,â or other circuits; â˘the knob itself contains no active electronics but must precisely âŁengage âthe shaft and maintain position under load to ensure correct cycle sequencing.
Technically, proper⣠replacement and troubleshooting require confirming shaft geometryâ and retention method: incompatible splines or incorrect bossâ depth willâ prevent correct engagementâ or cause slippage. Practical checks include verifying the⣠pointerâ aligns with the âoffâ index when the timer is at rest and rotating the knob âthrough full cycles while observing contact changes on the timer (or consulting the wiring âdiagram). Common failure âŁmodes are stripped⢠splines, fractured âŁbossesor worn detents; inâ repair⣠situations, â disconnect power before accessing the control, verify the shaft typeand test operation after â˘installingâ the knob âby running a short âcycle. Example diagnostic and compatibility considerationsâ are summarized below.
- Function:⣠mechanical input device that sets timer contact positions
- Behavior: indexed detents alignâ with timer cam positions for repeatable cycles
- Compatibility: must match shaft spline, boss depthand retentionâ method
- Diagnosis: inspect âsplines, verify pointer alignment, ârotate and observe timer contacts

How the 134011703 âFrigidaire Dryer âTimer âKnob Interfaces with â¤the Timerâ Mechanism âand Electrical Controls
The 134011703 Frigidaire Dryer⤠Timer Knob engages the timer mechanism throughâ a âprecisely machined splined bore and a keyed seating surface that mates to the timer âshaft. Rotation of the knob transmits torque to â˘the internal ârotary switch â¤and cam assembly, using âdetents or indexing features on the knob to produce discrete user-selectable positions. Proper⣠fit requires matching the spline âcount, bore⣠diameterand âinsertion depth so the knob⣠fully engages theâ timer shaft; an incompatible spline pattern or wornâ bore will cause slipping, missed index positionsor failure to actuate the timer cams. In practice technicians confirm fit by âŁverifying spline geometryâ and alignment of the pointer/stop soâ the selected setting⤠on âŁthe control panel corresponds to the internal switch position.
- Spline engagement: transfers â˘rotation â¤to the⢠rotary switch without electrical conduction.
- Detent/indexing: providesâ tactile feedback and âconsistent switch position selection.
- Mechanical stop or alignment âŁtab: prevents over-rotation⣠and âensures correct pointer alignment.
- Compatibility factors: âspline profile, shaft length, âand mounting retention method (push-on clip or threaded boss).
Theâ knob itself is âa mechanical interface; it⢠does ânot make or âbreak â˘electrical circuits but rather positions the⤠timerS internal âcontacts. As the knob turns,the rotary switch connects âdifferent contact sets that direct power to the dryer âmotor,heating element,timer motor,and âŁanyâ sensing âcircuits; such as,a timed-dry position will energize the timer motor and heater circuits until the⣠selected time âelapses,whereas an â˘automatic âcycle routes thermostat and cycling contacts⢠to maintain temperature.Common failure modes seen⢠in the field include a stripped spline that allows the knob to rotate⣠while the timer remains stationary,or a broken â˘retention feature that prevents stable selection; replacing the knob with one matching⣠the original spline and retention style âŁrestores correct âŁmechanical control of the timer and electrical sequencing.

Common Failure Symptoms and Diagnostic Indicators of a Malfunctioning⤠Timer Knob
The 134011703 Frigidaire Dryer timer Knob acts as the âuserâ input interface that transmits rotationalâ motion⣠to the dryer’s timing mechanism or electronic selector. âIn mechanically timed models the knob engages a splined shaft and detent assembly to index cam-operated switch â¤contacts; in electronic controllers⣠it âŁmay operateâ an âencoder or micro-switch.⤠correct function is indicated by âŁfirm engagement on the shaft, distinct detents or clicks as settings â¤changeand minimal lateral play.Failure modes that effectâ compatibility and behavior include stripped splines, a fractured hub, â¤worn detentsorâ an incorrect replacement knob that does ânot match the âŁshaft geometry – each of whichâ can produce symptoms ranging from aâ loose-feeling control toâ complete lackâ of timer⣠advancement.
Effective diagnosis combines visual/mechanical inspection with simple âŁelectrical checks: remove the knob⣠to inspect spline condition and hub integrity, rotate âŁthe underlying shaft while observing switch continuity or encoder outputandâ verify that the knob âŁseats flush against the control panel.â Common observable indicatorsâ include the knob turning without changing cycles, intermittent or skipped⤠settingsor excessive wobble that misaligns the pointer; these guide whether the repair âŁrequires a replacement knob, âa new timer shaft, â˘or further electronic âtroubleshooting. Practical tests include measuring continuity across timer contacts while rotating â˘the shaft, comparing fitment against a known-good knoband checking for⢠debris or melted plastic that would prevent proper⢠seating.
- Knobâ spins freely – stripped spline or broken hub causing loss of mechanical drive.
- No detents orâ soft clicks -â worn⢠or⣠missing detent spring⢠preventing âindexed positions.
- Timer does not advance – could be slipping knob, failed timer motor, â˘or⣠faulty electronic â˘encoder.
- Intermittent operation – cracked plastic, debris⢠obstructing engagementor â¤intermittent⤠switch contacts.
- Excessive lateral wobble â- incorrect part fit or damaged shaft/bushing alignment.

Replacement Considerations, Compatibility Checksand installation Procedure â¤for âthe Timer Knob
The 134011703 Frigidaire â¤Dryer Timer Knob âserves as the mechanical interface between the user and â˘the dryer’s timing mechanism, translating rotational input â¤into discrete timer positions through a âsplined or keyed hub and detent system.In âŁmany Frigidaire dryers this âŁknob couples âdirectly to an electromechanical⤠timer shaft or to the⢠selector shaft of an electronic timerâ module; correct engagement requiresâ matching the knob’sâ internal bore profile and retention âmethod to the appliance shaft.â Technicians should â¤inspect the⢠shaft for worn splines, corrosion,⤠or missing key flats and verifyâ the knob’s⣠retention type (pushâon, threadedor setâscrew) â˘before installation so the controlâ pointer aligns precisely with âthe â˘timer face and detents provide repeatable stops during âcycle selection.
Replacement and installation âŁare â˘straightforward â˘but require⤠methodical checks to avoid âmechanical or functional faults: disconnect power, confirm the part number againstâ the dryer’s parts⣠list or service diagramand identify the shaft⣠interface by counting splines or checking⣠for a Dâflat. During installation, remove the âŁold knob with a firm straight pullâ or by loosening the set screw,â clean theâ shaft of debris, align the knob’s index with the timer faceand seatâ the knob until âits retention engages; avoid â¤excessive force that can âcrack thermoplastic components. After mounting, verify smooth rotation through all positions, confirm âŁdetent engagement and accurate pointer alignmentand run a âshort cycle to â¤ensure the timer advancesâ correctlyâ and the new knob does not introduce wobble or intermittent contact.
- Verify â¤part number⤠and cabinet/service diagram compatibility before⣠purchase.
- Identify⤠shaft type (splined,Dâflat,threaded) and retention method (pushâon vs. setâscrew).
- Safety first: disconnect electricalâ power before removing or installing the knob.
- Inspect/clean the shaft, align index marks, seatâ knob fully, then test detents and timer operation.

Q&A
What is the 134011703 Frigidaire dryer timer âknob and âwhat does⣠it do?
The 134011703 is the control knob thatâ mounts on the dryer timer or cycle selector âshaft. It providesâ a mechanical⢠interface so âthe user can selectâ cycles, set drying timeor turn the timer on/off. the knob itself does not contain electrical components; it transmits the user’s selection to the timer mechanism behind the control⢠panel.
how do I know âif 134011703 is compatible with my â¤Frigidaire dryer?
Checkâ your dryer’s model number (usually on a tag on⢠the door⣠frame or ârear panel) and compare it with the parts compatibility âŁlistâ from Frigidaire orâ a reputable parts supplier. âŁAlso confirm the physical fit: the knob’s spline/profile and mounting method must match the timer shaft âon your dryer. If in doubt,search the part number plus your dryer model or contact the parts dealer withâ both numbers to verify fit.
How can I tell if the knob itself is the problem âor ifâ the â¤timer mechanism is faulty?
Common knob problems are visible damage, âcracks, stripped internal splinesor slipping onâ the shaft. â¤If the knob turns freely without moving the timer shaftâ (or visibly⤠slips),the knob is likely â¤the issue. If the âknob turns âthe shaft but the dryer⢠doesn’t start or âthe âtimer doesn’t advance, the problem is âprobably the timer assembly or associated electrical â˘components, not the knob.
Can⢠I replace the â¤134011703 knob myselfand what safety precautions should⢠I take?
Yes â˘-⤠replacing a knob is usually straightforwardâ and something âa âhomeowner can do. Always unplug the dryer or âshut⣠off its âcircuit âŁbreaker before accessing the control panel. Many⢠knobs âare removed by âpulling them straight âoff a splined shaft or by â˘loosening a small set screw. After installing the new knob, confirmâ it engages the shaft securely and â˘operates the timerâ correctly. If you must open âŁthe control console or handle⣠wiring, consider a qualified technician.
What tools do I need and how long does a⣠replacement typically⤠take?
Most knob replacements require minimal tools: a flat-head screwdriver or a small hex/Allen key if there’s⢠a set screw,and possibly needle-nose pliers. The job usually takes 5-15 minutes once the dryer isâ powered down and you have â¤access to the knob.
If the new 134011703⢠knob doesn’t fix the problem, what should I⢠check next?
First âconfirm the new knob is properly âseated⣠and engaging the timer shaft. If⣠it is and the dryer still won’t âoperate or âthe timer â¤won’t advance, test or inspect the timer assembly, door switch, thermal fuse, start switch,â and power supply. These components affect dryer operation; if you’re⤠not agreeable testing electrical⢠parts, call a qualified appliance technician.
Is it okay to use an âaftermarket replacement instead of an OEM 134011703 knob?
Aftermarket knobs can be acceptable if they⤠match the original’s fit andâ function (correct spline âpattern, diameterandâ position of any set screws). OEM parts guarantee an exact match, while aftermarket options may be cheaper but vary in fit/finish. Buy âfrom reputable suppliers and verify a⤠return policy inâ caseâ the knob doesn’t fit.
Where can I buy the⢠134011703 â˘Frigidaireâ dryer timer knob and â˘what should âI look for when ordering?
Buy fromâ Frigidaire’s official parts store, authorized dealers, large appliance-parts retailers, â˘or trusted online âŁmarketplaces. When â˘ordering, confirm the â˘part number, â˘your dryer model numberand check images and descriptions for spline type and mounting âstyle.⣠Also reviewâ shipping times, return âpolicyand any warranty in case the part is defective or incorrect.
