134011703 Frigidaire Dryer âTimer Knob is aâ frontâpanel user control designed to engage adn index a dryer’s mechanical or⣠electromechanical timer shaft; it⤠is a replacement knob that fits âonto the control shaft to allow theâ operator â˘to selectâ drying cycles and setâ run times. As a mechanical interface component, the knob provides the tactile detents and visual position reference needed to positionâ the internal timer⣠mechanism⣠or switch pack; its geometry, âspline or pushâfit connectionand retention method determine⣠compatibility with specific Frigidaire control housings.
Inside the appliance, the knob transmits human input to⤠the timer assembly or control module â¤and thus indirectly âcontrols power routing to subsystems such as⤠the⤠heating âelement, drive motorand cycleâdependent safety interlocks. When rotated, it either drives a mechanical cam timer or actuates a selector on an electronic control, changing which âŁinternal contacts are closed and which circuits are energized.⤠The knob itself does⣠not carry mains power, but improper fit or damage â˘can prevent correct timer⢠indexing, impair selector switch engagement,⣠or allow unintentional movement that affects heater operation⤠and cycle sequencing.
In the body of this article readers⣠will find âa technical overview of the knob’s function and physical characteristics, guidance on compatibility (spline types, mounting and retention), common failure symptoms and diagnostic checksand⢠practical⤠considerations for replacement. âCoverage includes how to identify worn⣠or mismatched knobs, inspection points to differentiate knob failures from timer or control failures, basicâ troubleshooting âsteps to confirm engagement and continuityâ of associated âswitches, âand the âkey factors to observe when sourcing and installing â˘a correct replacement while âfollowing standard safety precautions.

Function and Role of the âDryer Timer Knob: Mechanical,Electrical,and UserâInterface Responsibilities
The 134011703 Frigidaire âDryer Timer Knob serves âŁas⢠the operator’s mechanical interface to the âdryer’s timing/control assembly,converting rotational user input âinto discrete positions⤠that index the internal timer switch or cam. As âa component it has three distinctâ responsibilities:⤠a mechanical role that secures⤠to the control shaft and provides âreliable detents and torque transmission; an electricalâinterface role âby accurately positioning the timer mechanism so âelectrical contacts makeâ or break as intended; and aâ userâinterface role that supplies a clear pointer and tactile feedback for cycle selection. Technicians should treat the knob as aâ precision coupling: worn splines or a loose hub âwill allow âthe timer âto be mispositioned even though the timer motor and contacts remain functional, âproducing symptoms such as partial⤠cycles, failure to⣠advanceorâ an inability to select specific â˘settings.
- Key features: pushâon hub geometry compatible with the dryer’s control shaft, molded thermoplastic construction for âheat resistanceand indexed detents for positive position feedback.
- Common âsymptoms of failure: freeâspinningâ knob (stripped âhub), â˘misaligned⣠pointeror intermittent contactâ actuation despite a working timer motor.
- practical check: remove âthe knob to inspect hub âshape and seating;⢠a firm tactile engagement and absence of lateral play are required for⢠correct operation.

| Part | 134011703 frigidaire Dryer Timer Knob – replacement control knob for compatible âFrigidaire dryer âtimer assemblies |
| Mounting | Pushâfit over control shaft; hub âprofile must match the existing shaft geometry for secure coupling |
| Material | Molded thermoplastic with⣠friction âdetents; nonconductive âŁbodyâ isolates user âŁfrom live circuits |
| Function | Provides mechanical coupling, positional indexing,⤠and precise actuation timing for internal switch cams |
replacing the knob âis a lowârisk service âoperation, but correct selection requires matching the hub profile and knob diameter to the dryer’s control panel. If aâ dryer exhibits timing errors or contact chatter, verify the â¤knob engagementâ first – âslipping or worn engagement can mimic electrical failure – then⢠proceed to test⢠the timer motor and âswitches with a multimeter. Installing a correctly matched knob restores accurate user â˘input and pointer alignment; it does not, however, repair failed timer motors or⢠burned switch contacts, which require replacement of the timer assembly itself.
How the 134011703 Frigidaire Dryer Timer â¤Knob Works inside the Appliance: Internal Mechanism, Switchâ Matrixand Signal Path
The 134011703 âŁfrigidaire Dryer Timer knob is a mechanical user⣠interface âthat indexes the timer shaft and positionsâ the internal cam stack inside the dryer timer assembly. Turning this⢠knob does not directly â˘switch power; âinstead it rotates the timer shaft so that molded cam lobesâ or aâ wafer-style contact âassembly actuate a series of micro-switches and contact â˘fingers. In practical terms, selecting a timed cycle versus an automatic dryness setting changes which⢠cam lobes engage which contacts, routing mains voltage to the drive motor, heater circuits, moisture-sensing inputsor auxiliary thermostats according to â˘the chosen program. Replacementâ or compatibilityâ concerns usually âfocus on spline fit âand detent indexing-if the knob slips on the shaft or the spline profile is incorrect the timer will not select positions reliably evenâ when the internal contacts are⣠intact.
Internally the timer â¤uses a cam-driven switch matrix to form the signal path: cam lobes pressâ switch actuators that close or open specific⣠contact pairs, âso electrical paths are made from the âŁincomingâ supply throughâ safety âthermostats and⣠then âto âthe motor or heatingâ elements as required⢠by the âcycle. Common technician checks⢠include verifying continuity between expected contact pairs at specific knob â¤positions, inspecting the cam â˘surfaces for wear that can cause intermittent contactand confirming that detents advance â¤the shaft⣠toâ the âcorrect index. Typical symptoms⤠that implicate the knob/timerâ interface include failure to start with the knobâ in â˘a given position, the unit running with no heator the timer skipping âpositions under load; thes point to mechanical wear, poor spline engagementor degraded switch contacts rather than a judgment error âby the user.
- Features: âdetented indexing,spline fit to timer shaft,mechanical â˘cam-to-switch actuation.
- Common failure signs: slipping⢠knob,intermittent cycle changes,no start in specific positions.
- Diagnostic approach: check mechanical â˘engagement, continuity of switch matrix at indexed positions, inspect cam lobes and âcontact tips.

Common Failure Symptoms and Diagnostic Indicators for Timer âŁKnob and Timer Module Malfunctions
The 134011703 Frigidaire Dryer Timer Knob is the mechanical interface that transfers the user’s rotational inputâ to the⤠dryer’s timer or selector mechanism. It relies on correct⢠spline geometry, shaft diameter,â and⤠detent indexing toâ positionâ internal cams or switch wafers⤠precisely; incorrect fit or worn splines will allow the knob to rotate without changing the timer state. In Frigidaire⢠units the knob may engage either a cam-type mechanical timerâ or an electronic encoder module, so replacement knobs must match the original alignment marks and stop positions to ensure the selected program corresponds to the intendedâ electrical contacts âŁinside the timer assembly.
Typical failure symptoms and diagnostic indicators allow technicians to distinguish knob problems from timer-module faults. Symptoms such as a free-spinning knob, âmissing detentsor visible broken plasticâ generally indicateâ a mechanical knob failure; electrical symptoms like unchanged continuity across timer terminals while the⤠shaft is rotated point to a module fault.Practical â˘checks include inspecting spline⤠teeth and detents âunder magnification, confirming⣠a snug fit on âthe shaftand measuring continuity orâ resistance across timer contacts while actuating the shaft; if mechanical rotation causes contact changes but the user interface does not reflect them, the âŁknob is âŁdefective, whereas if rotation âdoes not change contacts⢠the âtimer module⤠needs replacement orâ repair.
- Free-spinning knob – check spline engagement and⤠detent spring tension.
- Intermittent cycle changes – inspect⣠splineâ wear and test timer contact continuity while rotating the shaft.
- Knob stops not aligning â¤with cycles – verify alignment marks and compareâ geometry to the original âŁ134011703 part.
- brokenâ hub or clip – visual âreplacement required; confirm replacement matches shaft profile.
| Item | Description |
|---|---|
| Spline â˘fit | Correct spline count and snug fit ensure torque transfer; worn splines cause slip under load. |
| Detent âaction | Detents provide âŁpositive indexing; missing detents lead to ambiguous cycle selection. |
| Electrical continuity | Measure timer contacts while rotating shaft: changing states indicatesâ module responds; no âŁchange suggests module failure. |
| Visual damage | Cracks, clipped hubs, â˘or deformed detent âsurfaces indicate the knob â˘should be replaced rather than the timer module. |
Compatibility, replacement âŁConsiderationsand Installation Procedure for 134011703 and⢠Equivalent Frigidaireâ Timer Knobs
The 134011703 Frigidaire Dryer timer Knob is a user-interface component⤠that mechanicallyâ couples to theâ dryer âtimer’s control shaft to select â˘and indicate cycle positions. The knob transmits torque to a splined or keyedâ shaft and provides⣠an index marker for theâ timerâ cam or rotary switch. Proper function depends on matching the knob’s âbore geometry (splineâ count or Dâshaped key), retention method (push-on friction fit or setâscrew)and bezel clearance so the pointer âŁalignsâ precisely with the printed cycle markings on the control panel. In practice, many replacement knobs âŁwill physically fit multiple Frigidaire models, but electrical and mechanical position alignment must âbe confirmed to prevent â¤mis-selection of heatâ or timing modes during operation.
For replacement and installation,verify the shaft typeâ and measure bore diameter before ordering a replacement âor fitting an equivalent. Follow a âcontrolled installation sequence: power the dryer off and unplug it, remove the old knob by pulling â¤straight off â¤or loosening theâ set screw, inspect the shaftâ for wear or deformation, align the knob’s index marker with the “off” or reference position on the⣠timer, then seat the new knob fully and secure any set screw. After installation, run a short diagnostic cycle to confirm that the selector positions correspond to the expected timer settings and that the knob does⢠not slip under normal user torque. If a generic replacement is used,⣠ensure the pointer calibration and physical clearance at adjacent controls orâ bezels match âthe original toâ maintain safe and reliable operation.
- Installationâ checklist: power âdisconnected,shaft type matched,pointer alignment checked,retention secured,operational verification performed.
| Item | Description |
|---|---|
| Compatible shaft types | Splined (count varies), Dâshapedâ keyor smooth with set screw – measure before purchase |
| Mounting âmethod | Pushâon friction fit or setâscrew retention; setâ screws require appropriate torque to avoid shaft damage |

Q&A
What is the frigidaire part 134011703 â(dryer timer â˘knob)â and what does it do?
Part 134011703 â˘is a replacement control/selector knob for Frigidaire dryers. It mounts on the timer or cycle-selection shaft and lets the user choose drying cycles, set time or start settings. The knob itself is a â˘mechanical interface-it does not contain the electrical timer mechanism, but it transfers your⣠input to the timer/control shaft.
How can I tell if 134011703 will fit my dryer model?
Check your dryer’s model number (usually on a tag inside the door opening or on âthe rear panel)â and compare it to the part compatibility⢠list from Frigidaire or a â˘parts distributor. Also visually confirm the shaft âtype-many Frigidaire knobs fit a D-shaped⢠or âsplined⢠shaft.â If the knob description lists your â˘model⣠or shows the same shaft shape â¤and diameter, it should fit. When in doubt, provideâ the dryer model number to the partsâ seller.
How do I remove the old knob and install the 134011703 replacement?
Unplug the dryer (andâ shut off gas supply if doing otherâ gas-related work). Most knobs simply pull straight off a â¤D-shaped or âŁsplined shaft-grip the knob and pull âŁfirmly. Some knobs have aâ small set screw orâ retaining clip;â if present, â¤loosen the screw orâ removeâ the clipâ firstâ with a small screwdriver or⤠hex key. To install, âŁalign the knob⣠with the âŁshaft (match the flat on a D-shaft), slide it on until fully seatedand tighten any set screw if provided.
my knob spins freely butâ the dryer won’t âŁrun-how do I know if the knob or âthe timer is bad?
If the knob spins on the shaft without⤠moving the control shaft,the knob’s internal bushing⣠or splines areâ likely broken. If the knob turns the shaft but the dryer still won’t start or cycles aren’t changing, the timer orâ switch inside the control assembly is likely at⣠fault. To check: â¤remove the knob and manually turn the control⤠shaft (with pliers â˘or by hand if accessible).â If turning the â¤shaft operates⤠the dryer, the knob is âdefective.⢠If the shaft turns but the dryer still doesn’t â¤respond,test the timer/switch with aâ multimeter (only â˘after disconnectingâ power)â for continuity âŁat the appropriate timer terminals or consult⢠a technician.
What tools and precautions â¤are needed to replace this knob?
Usually no special âtools are required-many users can replace it⢠by⤠hand. You might need a â˘small screwdriver or allen key if the knob âhas a â˘set screw. Precautions: disconnect electrical power before working near controls, avoid forcing the âknob âonto â˘an incompatible shaftand keep small screws⤠or clips so they are not lost. Replacingâ just theâ knobâ does not normally require opening gas or electrical âŁcompartments,â but⢠if âŁyou do open panels,⣠follow âsafety procedures.
Is part 134011703 anâ OEM Frigidaire part orâ anâ aftermarket replacement?
Part number 134011703 denotes the specific replacement part; whetherâ a listing is OEM (genuineâ Frigidaire) or aftermarket depends on the seller. Many parts suppliers âsell the genuine Frigidaire knob â˘under that number, but some⣠retailers also offer lookâalike aftermarket versions. âŁIf OEM authenticity is critically important, confirm with the âsellerâ that theâ item is a genuine frigidaire/Whirlpool âGroup part.
Are there⢠different colors or finishes âavailable for this knob?
yes-manufacturer andâ aftermarket sellers â˘commonly offer knobs in âŁstandard finishes such as white, almond, bisque, black âor metallic trim to match control panels. when⤠ordering, verify the color and match it to your control panel or choose â˘the OEM color option for the best match.
The replacement knob fits but has some play or wobble-what can I do?
Slight play can be normal, âbut excessive âwobbleâ usually means the knob’s internal âŁbushing or the âshaft spline isâ worn orâ mismatched.First confirm the knob is the correct type⢠for your shaft (D-flat vs. splined). If⣠it is correct but still loose, replace the knob with a confirmed-fit OEM part. Do not use shims that could interfere with control engagement.â If the shaft itself is damaged, â¤the â˘control housing or âtimer⤠assembly may need repair or replacement by a qualified technician.
