202133â Speed Queen Top Load Washer Timer Knob is âa rotary âŁcontrol knob designed to mount on the â˘timer shaft of Speed Queen top-load washing machines; it functionsâ as the user interface for selecting wash cycles and âmechanicallyâ engages the timer âŁdrive.As âa mechanical coupling and selector, theâ knob transmits operator input to the timer assembly through a splined⣠or⣠keyed fit âŁand may include detents or indexing features to align selected positions with the internal â¤cam or switchâ stack.
Inside the appliance, the timer⣠knob interacts directly with the timer mechanism⤠and⢠indirectlyâ with subsystems âcontrolled by theâ timer, including â˘the drive motor, â¤waterâ inlet valves, drain pumpand agitation cycles. when rotated, the knob positions âthe timer’s internal contacts or cam âlobes to âŁsequence electrical power to thoseâ circuits, so its correct fit âŁand positioning are⤠essentialâ for⢠accurate âtiming⣠andâ reliable actuation of electricalâ contacts. Failure⤠of theâ knob to âfully engage the timer shaft can produceâ misalignment, â¤skipped positionsor intermittent control signals that affect overall â˘machine operation.
this articleâ will explain theâ knob’s functionalâ role in the control⢠chain, outline which Speed Queen models and timer types it is indeed compatibleâ with,⤠describe common failure symptoms⣠(for example stripped splines,⤠cracked plastic,⣠poor indexingor⣠looseness)and â¤provideâ diagnostic guidance for âŁvisual inspection and⢠basic continuity âchecks. It⢠will âalso cover â˘practical replacement considerations such as verifying âspline geometry and retention method, OEM versus â˘aftermarket fit concerns, mechanical alignment,⢠and safety precautions to observe when removing or installing the control on âlive electrical equipment.

Functional Role of⣠the Timer Knob in â¤Wash⤠Cycle Sequencing and user Control
The 202133 Speed Queen⣠Top Load Washer âTimerâ Knob is a mechanical user interface that mounts on the timer shaft to select and hold â˘the desired wash sequence. As⢠a rotary âcoupling, the â˘knob transmits operatorâ input to the internal âtimer camâ orâ switch assembly and âŁprovides discreteâ indexing (detents) and a â¤visual pointer for cycleâ selection. Although passive and nonâelectrical, the knob’s âfit, detent mechanism and pointer alignment âŁare critical for precise sequencing: an improperly seatedâ or worn knob can allow the shaft â˘to rotate out of index or â¤prevent the âtimer cam from engaging the correct âcontacts, â¤producing skipped steps⤠or incorrect cycle timing.
- Detent⢠positions for tactile feedback and⣠alignment
- spline geometry that mates âto the timer shaft for⣠torque âtransfer
- Pointer/indicator forâ visual cycle selection
- Material wear symptoms: cracking, rounded⤠splinesor loose⢠fit
Compatibility depends âon matching the knob’s spline profile, boreâ diameter andâ detent spacing to the washer’s timer shaft; aftermarket replacements âmust replicate these mechanical interfacesâ to restore proper⢠behaviour. Forâ practical troubleshooting, removeâ the knob to inspect for⤠broken⤠tabs or deformed splines, test that the timer shaft turns âsmoothly and indexes correctly,â and verify that the âpointer aligns with the timer âŁface marks during each detent. Replacing only the⢠knob will correct most userâinterface and indexing issues, but if symptoms persist (intermittent cycle changes or⤠failure to advance), the underlying âtimer cam or motor should be inspected â¤for wear or electrical faults.

How the 202133 Speed Queen Top Load Washer âTimerâ Knob â¤Operates within âŁthe Mechanical and Electrical Control System
The 202133 Speed â¤Queen Top Load Washer Timer⣠Knob converts user input into precise mechanical rotation that indexes the â¤internal timer camâ and selector switches.â It mounts onâ the timerâ shaft via a splined or keyed⤠bore and uses detents or a spring-loaded catchâ to provide tactile⤠position feedback; this mechanical interface ensures the cam â¤rotates to discrete positions that correspond âto âwash,⤠rinse, spin â¤and off states. In practice, technicians should confirm â˘spline count â˘and shaftâ length beforeâ replacement âbecause mismatchedâ engagement will⤠prevent âcorrect cam⢠indexing or may⣠leaveâ the âknob loose âon the shaft, producing intermittent or incorrect cycle selection.
The knob does not directlyâ switch electrical circuits; instead each knob⢠position aligns âŁthe timer cam to actuate mechanical switch âcontacts that route mains power to the motor, water inlet valve, heater⢠(if âpresent) and drain pump âaccording to the âmachine’s sequence. Symptoms such⤠as âinability to select cycles,⣠a knob that âspins without changing the washer stateor erratic transitions âtypically indicate âworn splines,â broken detents,⤠or âŁa slipped knob⣠rather than an electricalâ fault. For diagnostics,â verify that each indexed position corresponds toâ the expected contact closures on the timer using a multimeterand replace the âknob with a compatible unit that matches shaft profileâ and retention method for reliable operation.
- Mechanical engagement: splined/keyed⣠bore and âdetents for indexing
- Electrical behavior:⣠positions align cam to close â˘specific switch contacts
- Compatibility concerns: spline count,shaft length,and âretention clips
- Common symptoms: âŁloose/spinning âknob,missed cycleâ changes,intermittent contact actuation
| Item | Description |
|---|---|
| Mount interface | Splined â˘or keyed⣠bore that must match timer shaft â¤profile |
| Function | Indexes timer cam⢠positions âŁto sequence electrical switch closures |
| Diagnostic check | Confirm âdetent indexing and use a multimeter to verify contact changes per position |
Common Failure â˘Symptoms and Measurable Diagnostic Indicators ofâ Timer Knob Faults
The user interface knob transmits âmanual position selection to the timer assembly and must seat precisely â˘on âthe timer shaft â¤to operate the cam-driven switch pack. The 202133 âSpeed queen Top Load Washer Timer knob is a direct-fit actuator designed to engageâ the timer spline and detent mechanism; if theâ knob is worn, crackedor â¤the spline âis loose⢠the selector position will notâ reliably correspond to the timer’s internal contacts. Technically, âthe knob contributes no electrical âfunction but â¤any mechanical play,⤠stripped splinesor missing detents changes the rotational relationship between âthe operator input and the cam-drivenâ contact sequence, producing symptoms â¤that mimic electrical timer â¤faults or control⣠board errors on compatible Speed⤠Queen top-load models.
Common failure symptoms map to measurable electrical and âmechanical indicators that a⣠technician â˘can verify with â¤hand tools.â Use âa multimeter to check continuityâ and contact resistance while turning the selector, measure line voltage to the timerâ input (nominally â~120 V âAC⢠in âNorth American models) during âcycle changes, âand âŁinspect âŁfor mechanical play or visual damage at the spline and detent.â Practical examples: âa knob â¤that rotates freely but the timer does not advance usually shows no change in contact continuity when⣠the shaft is âturned;â a timer⤠that stops mid-cycle but the knob still â¤clicks indicates intermittent contact resistance or⢠a failing⤠timer motor winding.
- Knob slips on⤠shaft – Measurable indicator: ârotational movement of the knob without corresponding change at the timer shaft/detent; visible spline wear or reduced torque required to âturn.
- No cycle advancement (stuck on a setting) – âŁMeasurable indicator: no continuity change across selector â˘contacts while ârotatingor â˘absence of expected voltage pulses to the timer motor.
- Intermittent or skipped âcycles – Measurable indicator: fluctuating âcontact resistance or intermittent continuity âwhen rotating the switch pack; inconsistent audible stepping from the timer motor.
- Burning smell âor overheating nearâ knob -â Measurable â¤indicator: discoloration or â¤melted⤠plastic atâ the knob âbase and elevated⢠contact resistance measured⤠across timer contacts.
- Erraticâ electronic behavior (control board⣠reports timer âŁfaults) – Measurable indicator:â missing or irregular lineâ voltage at timer inputâ terminals or transient voltage spikes during knob operation.
| Item | Description |
|---|---|
| Contact â˘continuity | verify continuity⢠and stable low contact resistance acrossâ switch positions â¤while rotating the selector. |
| Mechanical â¤spline/detent | Inspect forâ stripped⤠splines, excessive â¤axial playor absent detents that decouple knob position from the timer shaft. |
| timer â¤motor coil | Measure coil resistance for open⣠or âshort conditions âand â¤confirm motor receives expected â¤voltage pulses during cycle advance. |
| voltage input | confirm nominal line voltage at timer input⢠and steady supply â˘during commanded⣠cycle transitions. |
| Visual/thermal signs | Look for discoloration,melting,or⤠odor â˘and âcorrelate âŁto increased resistance or intermittent contact behavior. |
compatibility, Replacementâ Considerationsand Installation Procedures for the 202133 Timer Knob on Supported Speed Queen âModels
theâ 202133â Speedâ Queen Top⣠Load Washer Timer â˘Knob is a mechanical interface component â¤that transmitsâ user âinput to the timer/cam assembly; itâ does not⢠contain active electronics. It must match â¤the control shaft profile â˘(splined or D-shaped), detent geometryand bezel clearance of the specific Speed Queen top-load control plate toâ engage the timer â¤cams and internalâ switches correctly. Technicians should verify physical⢠fit by comparing shaft profile, retaining clipâ locationandâ the knob’s internal bore⣠before installing a replacement, âas compatible models⢠share the same shaft and⣠bezel âgeometry while some later or â¤choice models use âdifferent knobs or retainers.
Replacement and installation are straightforward but âŁrequire verification and âŁcareful alignmentâ to avoid functional issues. Prior to removal, disconnect⣠power to prevent unexpected motorâ starts; then inspect the existing knob and control shaft for damage â˘or plastic deformation.Typical âinstallation involves removing the old knob (pulling âstraight off the shaft âor releasing a retention clip), cleaning debris from the shaft, aligning the knobâ indexâ with the⤠OFF or PARK mark on the bezel,â andâ pressingâ the knob fully until it seats⢠with theâ detents. After installation, rotateâ the knob through âits full range to confirm smooth engagement of âŁdetents and correct alignment with cycle positions; â¤symptoms ofâ an improper fit include slipping under load, misalignment of selected cyclesor â¤broken pointer tips. Practical considerations: do â˘not âmodify the knob bore to forceâ a fit, replace any damaged retaining clips, âand verify⢠operation with an empty âor drained tub before returning the washer to service.
- Key â˘checksâ before replacement:â shaft profile match,â retainer condition, pointer alignment.
- Installation steps: power off, remove âold knob, clean shaft, align index, press to seat, functional test.

Q&A
What is part number⤠202133 and which machines does it â¤fit?
Part number 202133 is a replacement timer/control knob designed for certain Speed Queen â˘top-load âŁwashers. â˘It is a mechanical knob that mounts to the washer’s âtimer/control shaft.â Fitment depends on the washer model⤠and âthe spline size/pattern of â˘the control shaft, so confirm compatibility byâ checking your washer model number or comparing the existing knob’s spline count and overall dimensions withâ the replacement listing âbefore ordering.
How do I remove the âoldâ timer knob and install the 202133 replacement?
alwaysâ unplug⣠the washer before⢠starting. Many⤠knobs simply pull straight off the splined shaft-graspâ the knob firmly and pull â¤outward. If⤠there is a retaining clip or set screw, â¤remove it âfirst.⢠To install the 202133⢠knob, align â¤its index mark with the timer’s OFF⣠position and âŁpressâ it straight⣠onto â¤the splined shaft until fully seated.If a clip or screw âwas âused, reinstall it. No special tools are âŁusually required,â though âa small⢠flat âscrewdriver or pliers can help remove clips âcarefully.
My new knob fits on the shaft but the timer does not advance-did I get⣠a bad â˘part?
If the knob turns the shaft but âthe washer won’t advance through cycles, the âproblem is likely the âinternal timer or control mechanism,â not âthe knob. The knob is justâ an interface â¤that turns or engages the timer. Verify that the knob isâ fully seated and â˘that any push-to-start feature is functioning;⣠if the internal timer â¤or⣠electrical control⢠is faulty you’llâ need â˘to replace or repair thatâ componentâ rather than â˘the knob.
What should I check if the knob is looseâ or keeps slipping onâ the shaft?
First inspect the splines on â¤both âthe shaft and theâ knob⢠forâ wear or damage-stripped splines cause slipping. Check for a missing retainingâ clip or â¤set⢠screw that â¤secures the â¤knob. If splines are damaged, replacing â¤the knob may not be enough; you may need the timer/control âassemblyâ or aâ keyed adapter. Also ensure the knobâ is the correct part for your spline pattern (count and profile).
Are there differentâ colors or finishes âŁavailable for the 202133 knob?
Replacement knobs can come in âŁdifferent â¤colors (white,black,almond,etc.) depending âon âŁthe manufacturer or retailer. Availability varies, so âcheck product listings or contact the seller for color options âto âmatch yourâ washer’s control panel. OEM Speed Queen replacements may have a limited color selection consistent with factory finishes.
Do I need âany âspecial tools âor⤠calibration after installing the knob?
No special tools â˘or calibration are normally required. Installation is typically a simple pull-off and âpush-on operation. After⢠installing,rotate the knob through âits positions to âconfirm smooth engagement and verify the indicator aligns with the OFF andâ cycle positions. If your âwasher uses an âelectronic control⣠with software calibration,replacing a purely mechanical knob â˘will not require reprogramming.
How can I âŁtell if I should replace the knob or the entire timer/controlâ assembly?
replace just the knob if it is cracked,â fadedor⢠its splines are intact and âthe â˘timer/control âŁfunctions normally. If the knob is intact but âthe⣠washer âfails to change cycles, has electrical/control faultsor theâ shaft splines are stripped/damaged, you may need the entireâ timer/control⢠assembly. diagnose by confirming whether âmanual rotation⢠of the â¤shaft (with the â˘knob removed) physically⣠advances the timer mechanism.
Is â¤the 202133⢠knob an OEM Speed Queen part and does it have a warranty?
some 202133 listings are OEM Speed Queen replacements and âŁothers may be âaftermarket equivalents-check the product description and seller for âOEM designation. Warranty length and⢠coverage depend on â˘the âseller or manufacturer; many replacement parts include a limited warranty âŁ(for exampleâ 90 days to one year). Verify warranty terms⤠at the time ofâ purchase andâ keepâ your receipt or order information for any claims.
