134011703 Frigidaire Dryer Timer Knob is a replacement control knob designed for the timer/selector shaft of select Frigidaire dryers; it is a mechanical user-interface component-typically an injection-molded knob with a specific internal spline or D-shaft profile-that mounts to the timer or rotary selector on the dryer control panel.As a physical interface, the knob provides a tactile means for the operator to set cycles, times, or heat settings and includes an indicator mark to show the selected position relative to the timer or cam assembly.
Inside the appliance, the knob interfaces directly with the timer or selector shaft and thus affects the mechanical or electromechanical sequence controller that governs motor start/stop, heater element energization, and cycle timing. Depending on the dryer design, turning the knob either moves a mechanical cam that closes and opens internal contacts or adjusts a rotary switch or encoder that sends electrical signals to the control circuitry; consequently, the knob’s fit, orientation, and detent indexing are significant to ensure correct physical engagement and accurate signaling to the dryer’s control systems.
In this article readers will find a technical overview of the 134011703 knob’s function, how to verify compatibility with specific Frigidaire timer shafts and control assemblies, common failure symptoms (such as cracking, stripped splines, misalignment, or loss of detent/positioning), and step-by-step troubleshooting checks to distinguish knob issues from timer or electrical faults. The guide will also cover practical replacement considerations-matching the spline profile, ensuring proper retention, avoiding damage during removal or installation, and safety steps such as disconnecting power-so technicians, engineers, and appliance owners can make informed repair decisions.

Function and Role of the Dryer Timer Knob in Cycle Selection and Control
The 134011703 Frigidaire Dryer Timer Knob serves as the mechanical user interface that selects and engages the dryer’s timing and program circuits. When the knob is turned, it rotates the timer shaft, positioning cams and switch wafers inside the timer assembly so that specific heater, motor, and indicator circuits are closed or opened according to the selected cycle. Compatibility depends on matching the knob’s spline or shaft bore and detent pattern to the timer shaft; a correct replacement restores precise angular stops and tactile indexing, which are necessary for reliable circuit timing and repeatable cycle selection.
functionally, the knob differentiates between timed and automatic programs by choosing the timer cam profile or the sensor/thermostat control path; in a timed cycle the selected position defines how long the timer motor will advance, while in sensor-controlled cycles the knob selects the control logic used by the machine. Practical diagnostics include checking for stripped splines, a loose retaining nut, or worn detents when the selector slips or fails to change programs, and confirming continuity on the timer switch contacts after replacement. Technicians should verify shaft dimensions and detent alignment before installing the knob to ensure correct mechanical engagement and expected cycle behavior.
- Primary functions: user selection, mechanical indexing, electrical circuit engagement
- Common failure symptoms: slipping on shaft, loss of detent, inconsistent cycle selection
- Installation check: confirm spline/shaft fit and retention method
- Service tip: test timer contacts after knob replacement to isolate electrical faults

How the 134011703 Frigidaire Dryer Timer knob Works Inside the Appliance – Mechanical and Electrical Interface
The 134011703 Frigidaire Dryer Timer Knob is the user-facing interface that transmits rotational input to the dryer’s internal timer mechanism. Mechanically, the knob is a splined bore or adapter that fits over the timer shaft and provides indexed detents so the operator can select timed cycles or automatic settings. Electrically, turning the knob repositions cams or a rotary switch stack inside the timer assembly that make and break circuits feeding the motor, heating element, and control relays; the knob itself does not carry current but must seat precisely on the timer shaft to ensure accurate contact sequencing. When evaluating compatibility, match the knob’s bore profile and retention method (press-fit, threaded collar, or clip) to the dryer’s timer shaft rather than relying on model numbers alone to avoid slip or misalignment during cycling.
- Key features: indexed detents for selection, splined bore for positive drive, and physical retention to maintain alignment.
- Electrical interface: knob positions cams/switches inside the timer-no direct electrical conduction through the knob.
- Common symptoms of failure: knob slips on the shaft, cycles don’t engage correctly, or settings jump between detents.
- Practical checks: confirm spline profile and retention hardware, inspect for plastic wear or cracked mounting bosses before replacing the timer assembly.
In practical troubleshooting, a knob that rotates freely while the timer shaft stays stationary indicates mechanical wear or a missing adapter; conversely, a knob that moves the shaft but the dryer does not respond points to worn contacts inside the timer or wiring/connectors downstream. Technicians should observe tactile feedback (clicks at detents), measure continuity across timer contacts at selected positions, and compare shaft geometry to replacement knobs to ensure correct engagement. For repairs, replacing the knob is a low-cost first step when fit issues are evident, but intermittent heating or inconsistent cycling usually requires inspection or replacement of the internal timer/switch pack rather than the knob alone.

Common Failure Symptoms and diagnostic Indicators of Timer Knob Malfunction
The 134011703 Frigidaire Dryer Timer Knob is the mechanical interface that couples the user’s rotational input to the dryer’s timer assembly. It must match the timer shaft spline profile and seating geometry so torque is transferred precisely to the internal cam and switch stack; proper compatibility prevents slip,maintains detent indexing,and keeps the pointer aligned with the cycle markings. In normal operation the knob presents defined detents with minimal axial or radial play and transmits rotation consistently so the timer’s electrical switches change state at the intended angular positions.
Typical failures are either mechanical (worn or broken spline teeth,cracked hub,damaged detents) or electrical symptoms that appear because a compromised knob does not reliably actuate the timer switches. Perform a visual inspection for hub damage, check for excessive play by applying steady rotational force while observing the pointer, and execute a multimeter continuity test across the timer terminals while slowly rotating the knob to confirm switches change state at each detent. Practical diagnostic examples: a knob that spins freely without changing terminal continuity indicates a stripped hub; a knob that clicks but yields no continuity change indicates the internal timer contacts or cam have failed and require further testing or replacement of the timer assembly.
- Knob rotates freely or slips on shaft – indicative of worn/stripped spline hub.
- Pointer misalignment or excessive play – suggests loose seating or cracked hub affecting indexing.
- Audible detents without electrical response – points to internal switch/cam failure despite intact knob feel.
- Intermittent cycle selection or heating – may result from fatigued detents,debris in shaft interface,or intermittent switch contacts.

| Knob slip/wobble | Worn or cracked spline hub; verify spline count and shaft diameter and ensure positive torque transfer before reuse. |
| No continuity change | Multimeter shows no switch state change when knob is rotated; indicates internal timer switch or cam failure rather than external knob damage. |
| Intermittent function | Intermittent contact during rotation; inspect for foreign material in the shaft interface, loose mounting, or fatigued detent features. |
Replacement Considerations and Step‑by‑Step Installation for the 134011703 Frigidaire Dryer Timer Knob
The 134011703 Frigidaire Dryer Timer knob is the mechanical interface between the user and the dryer’s timing assembly; it transfers rotational input to the timer shaft and provides detented positions that correspond to specific cycles. Functionally, the knob must match the timer shaft’s inner spline profile and indexing geometry-differences in spline count, bore diameter, or keyway orientation produce slip, intermittent engagement, or inability to seat. Technicians diagnosing a non‑responsive dial should distinguish knob failures (stripped splines, cracked bore, worn detents) from timer mechanism faults, since a properly fitted knob will rotate the timer cam and actuate the switch stack without free play.
For replacement and installation, verify the knob’s mounting method (push‑fit, set screw, or retaining clip) and inspect the timer shaft for damage before assembly; replacing the knob will not correct electrical or mechanical failures inside the timer module. Follow safe,systematic steps: disconnect power and verify zero voltage,remove any securing screw or clip,pull the faulty knob straight off unless a fastener is present,align the replacement so its index mark matches the control panel reference,press or fasten it to full engagement,and cycle several positions to confirm positive detents and no binding.If the knob still slips after correct installation, measure spline dimensions and consider replacing the timer assembly rather than forcing a mismatched part.
- Disconnect power and verify zero voltage before starting.
- Inspect shaft splines, bore, and index notch for wear or deformation.
- remove retaining hardware (set screw or clip) if present; otherwise pull knob straight off.
- Align index marks and press replacement onto the shaft until fully seated or tighten set screw to specified torque.
- Test multiple timer settings to confirm detents and proper engagement; if slip persists, evaluate the timer module.

Q&A
What is the 134011703 Frigidaire dryer timer knob and what does it do?
The 134011703 is a replacement control knob that attaches to the dryer’s timer or cycle selector shaft. It gives you a grip to turn the timer or select cycles. The knob itself is not electrical - it mechanically engages the timer shaft to move the internal timer switch or selector mechanism.
How do I know if my dryer needs this specific knob (134011703)?
Check your dryer’s model number and the part number printed in the owner’s manual or on the parts list. You can also compare the shape, size and spline pattern of the existing knob to photos/specs for 134011703 available from parts suppliers. If the part number on the old knob matches 134011703 or the spline/shaft match, the part should be compatible.
What are common signs the timer knob is bad and needs replacement?
Typical signs include: the knob slips on the shaft (stripped splines), the knob cracks or breaks, the knob won’t stay on the shaft, or it turns without operating the timer. If the knob turns freely without moving the timer shaft, the internal spline is highly likely stripped and the knob should be replaced.
Can I replace the 134011703 knob myself, and what tools are required?
Yes – knob replacement is usually a simple DIY job. Basic tools: none in most cases, or a small flat-head screwdriver if there is a retaining screw. For stuck knobs you may need a towel and pliers for better grip. Always disconnect power (unplug or turn off the breaker) before servicing the appliance as a safety precaution.
How do I remove and install this timer knob safely?
Turn the timer to the OFF position, disconnect power, then pull the old knob straight off the timer shaft. If there is a small centre screw, remove it first. Align the new knob’s spline pattern with the shaft and push it straight on until snug. Do not force the knob at an angle. Reattach any retaining screw if present, restore power, and test the control.
Is 134011703 an OEM part or are there compatible aftermarket knobs?
134011703 is sold as an OEM Frigidaire replacement part by authorized suppliers; aftermarket equivalents also exist and often fit and function correctly. OEM parts tend to match finish and tolerances exactly, while aftermarket parts can be less expensive but vary in fit. Always verify compatibility with your dryer model and check return policies.
The knob turns but the dryer still won’t start - could the knob be the problem?
If the knob turns but nothing happens, the knob may be slipping or the internal timer/selector mechanism may be faulty. Remove the knob to inspect the shaft: if the shaft turns when you rotate it, the knob was likely slipping. If the shaft does not rotate or the dryer still won’t start with a good knob, the timer, start switch, door switch, or wiring may be the issue and further electrical troubleshooting is required.
Were can I buy the 134011703 and how do I confirm it fits my machine?
You can buy the 134011703 from Frigidaire dealers, appliance parts stores, and online parts retailers. To confirm fit: provide your dryer’s full model number to the seller, compare the part number to your parts diagram, or visually compare spline type and dimensions with your existing knob. If unsure, request a compatibility check from the supplier before purchasing.
