134011703 Frigidaire Dryer Timer Knob is a user-interface control component for Frigidaire clothes dryers, designed as a rotary knob that mounts on the timer shaft to select drying cycles and timed settings. The part is a mechanical interface-typically a molded plastic knob with an internal spline or hub that engages the timer shaft-serving as the physical actuator that the operator turns to command the dryer’s timing mechanism.
Inside the appliance, the timer knob transmits user input to the dryer’s timer or selector switch, either directly rotating a mechanical timer cam or providing position feedback to an electromechanical or electronic control. Its function influences which switch contacts close and thus which subsystems are energized, including the timer motor or controller, heating circuit (for electric models), gas valve sequencing (for gas models), drum motor, and associated safety interlocks such as door switches and thermostats. Because the knob is the primary means of selecting cycle duration and mode, it must reliably engage the timer shaft and maintain a defined position to ensure predictable interaction with the dryer’s control logic and power circuits.
In this article readers will find a technical overview of the 134011703 Frigidaire Dryer Timer Knob, including how it functions as part of the timer assembly, typical model compatibility and mounting considerations, common failure symptoms (for example stripped splines, cracked hub, or intermittent selector engagement), and step-by-step troubleshooting approaches to isolate knob versus timer/mechanism faults. The guide will also cover practical replacement considerations-verifying fitment, assessing OEM versus aftermarket options, installation tips for proper engagement and retention, and safety precautions when servicing the control panel-to help technicians, engineers, and appliance owners make an informed repair or diagnostic decision.

Function and mechanical role of the dryer timer knob within Frigidaire control systems
The primary mechanical function of the 134011703 Frigidaire Dryer Timer Knob is to provide a robust user interface between the operator and the dryer’s electromechanical or electronic timing mechanism. The knob mounts to the timer shaft-typically via a splined hub or a keyed friction fit-and transmits rotational movement to the timer’s internal cam stack or rotary switch. That mechanical coupling selects discrete timer positions, enabling sequential activation of heater, motor, and cycling contacts. In electromechanical systems the knob’s indexed detents align the cam lobes to make or break specific switch contacts; in electronic timers it provides a calibrated reference for the control board or encoder. Correct fit (spline count, diameter, and retention style) is required for reliable operation and alignment of the pointer to the control panel markings.
From a practical maintenance viewpoint,the knob performs only mechanical indexing and does not carry electrical current,but its condition directly affects cycle selection accuracy. Common service symptoms that point to a failed knob include free-spinning without changing the cycle, off-center pointer alignment, or intermittent engagement of timer positions. Replacing the knob is a straightforward repair when splines are stripped or the retention clip has failed; however, technicians should verify that the underlying timer shaft and cam assembly are intact before concluding the knob is the sole cause. Examples: if the shaft turns and the dryer does not enter the expected heat phase, stripped knob splines are likely; if the knob feels lose but the dryer still cycles correctly, a worn retention clip might potentially be the issue.
- Common checks: spline engagement, retention clip condition, detent feel (indexing), and visual alignment to control markings.
- Failure indicators: free rotation, intermittent cycle selection, or misaligned pointer despite correct shaft movement.

How the 134011703 Frigidaire Dryer Timer Knob interfaces with the timer switch and control circuitry
The 134011703 Frigidaire Dryer Timer Knob is the user-actuated interface that couples directly to the dryer’s timer shaft, transmitting rotational position to the internal cam and switch stack. Its function is purely mechanical: matching the shaft spline, seating depth, and any retention method (press-fit or set-screw) ensures the knob delivers precise angular positioning and tactile detents so selected cycle positions correspond to specific cam profiles. A correctly fitted knob yields repeatable indexing of the internal switch cams; a worn or mismatched knob will slip on the shaft, causing misalignment between the knob pointer and the actual switch position and resulting in incorrect or intermittent circuit selection.
When the knob is turned,the rotary cam inside the timer assembly moves to open and close contact sets that route mains power to the heater,motor,thermostat,and the timer motor; the knob itself contains no electrical components but is critical to selecting which circuits the timer switch connects. Technicians commonly verify proper interaction by rotating the knob while measuring continuity across switch terminals or observing voltage to the timer motor at different knob positions. For practical replacement, confirm spline profile and mounting style, align the pointer to the known ”off” detent before final tightening, and test cycle positions under power to ensure the knob and timer switch produce the expected electrical behavior.
- Mechanical coupling: spline type and retention method determine fit and torque transmission.
- Indexing: detents/pointer alignment map knob positions to cam lobes and switch states.
- Electrical result: knob rotation repositions cam-operated contacts that route power.
- Troubleshooting tip: measure continuity while rotating to locate misaligned or non-actuating contacts.

Common failure symptoms and diagnostic indicators of a worn or faulty timer knob
The knob functions as the mechanical interface between the user and the dryer timer mechanism: the 134011703 Frigidaire Dryer Timer Knob fits over a splined timer shaft, provides indexed detents for cycle selection, and transfers rotational input to the timer switch shaft. When the knob’s internal spline or hub is worn, cracked, or has lost material from repeated use or improper removal, the rotational input can slip or fail to engage the timer actuator. Compatibility is determined by matching the spline profile, hub diameter, and detent geometry to the timer shaft on the specific Frigidaire model; an otherwise correct-looking knob can still be incompatible if the spline count or spacing differs, which will produce fit and indexing errors rather than electrical or control board faults.
Common diagnostic indicators of a worn or faulty timer knob are mechanical rather than electronic: excessive axial play, absence of distinct detent clicks, free-spinning without advancing the timer, or intermittent selection of cycles despite visible rotation. Technicians should perform a visual and tactile inspection, confirm a firm mating to the timer shaft, and verify electrical behavior by observing timer switch contacts with a multimeter while operating the shaft manually. When replacing, confirm the OEM number and spline specification to avoid repeats of slipping or mis-indexing; replacing a worn knob typically resolves symptoms where the timer mechanism and control board or else test good.
- Loose or wobbling knob that rotates without moving the timer shaft.
- No detent feedback or missing indexing clicks during selection.
- Intermittent cycle selection or dryer not starting despite knob movement.
- Visible cracks, stripped spline teeth, or deformed hub on inspection.

Compatibility, replacement considerations, and step-by-step installation for the 134011703 timer knob
The 134011703 Frigidaire Dryer Timer Knob is the user-interface control that mechanically couples the dryer’s timer shaft to the selector dial, converting user rotation into discrete timer positions. The knob’s internal bore and retention method determine compatibility: some dryers use a splined shaft that requires a matching internal spline pattern,while others use a D‑flat or a small set‑screw on a smooth shaft. Technicians should verify the shaft profile, panel thickness, and indicator alignment before ordering a replacement; a visually correct knob can still fail to seat or index properly if the internal spline count or depth differs from the original.
Replacement and installation are straightforward when the shaft type and retention hardware are known. Start by removing the old knob without twisting the timer mechanism-either by pulling straight off a friction-fit or backing out a set screw-then inspect the shaft for worn splines, bent keys, or plastic retaining clips that must also be replaced. If the new knob slips after installation,the usual causes are worn splines on the shaft or an incompatible internal profile; resolving that requires either a different matched knob or replacing the timer assembly. For safe installation, disconnect power before working behind the control panel and confirm the knob indexes to the OFF position before final seating.
- Disconnect power to the dryer and move it for access.
- remove the existing knob by pulling straight off or loosening the set screw; do not lever on the timer shaft.
- Inspect and clean the shaft; replace any damaged retaining clip or set screw.
- align the new knob’s pointer/index to the OFF or home position and slide it onto the shaft untill fully seated; tighten the set screw if present.
- Restore power and rotate through positions to verify detents, electrical engagement, and that the knob does not slip.

Q&A
What is the 134011703 Frigidaire dryer timer knob and what does it do?
The 134011703 is a replacement timer control knob intended for certain Frigidaire dryers. It is the user interface that mounts to the timer shaft and allows you to select drying cycles or set the duration. The knob transmits your input to the internal timer/timer shaft so the dryer control can advance through the selected cycle.
How do I know if the 134011703 knob will fit my dryer?
Fit is determined by the dryer model and the shape of the timer shaft (splines or shaft diameter) and any retainer design. Confirm compatibility by checking your dryer’s model number against the part number on the manufacturer website or an authorized parts supplier.You can also visually compare the splined bore and knob indicator to the existing knob: the splines must match and the knob should seat fully on the shaft.
How do I remove the old timer knob and install the 134011703 replacement?
First unplug the dryer or disconnect power.Most Frigidaire timer knobs are friction-fit and simply pull straight off the timer shaft-grip firmly and pull straight back. If there is a set screw,loosen it with a small screwdriver or hex driver before pulling. To install the new 134011703, align the knob’s splined bore with the timer shaft splines, push the knob straight on until it seats, and tighten any set screw if present. restore power and test operation.
The replacement knob fits but the timer still won’t turn-what could be wrong?
If the new knob fits but the timer mechanism doesn’t advance or the dryer won’t start, the problem may be internal: stripped timer gears, a broken shaft, a faulty timer motor, or an electrical/control issue. A knob only provides mechanical input; if the timer internals are damaged you’ll need to replace the timer assembly or diagnose electrical faults (check continuity, fuses, door/lid switches, heating elements and thermostats) or call a qualified technician.
My old knob’s splines are stripped-can the 134011703 still work?
only if the timer shaft splines are intact. If the knob splines were stripped but the shaft is undamaged, replacing the knob with a correctly matching 134011703 will restore operation. If the timer shaft splines themselves are damaged, replacing the knob alone won’t help-you will need to replace the timer control or the entire timer shaft assembly.
Are there OEM and aftermarket versions of part 134011703 and does it matter which I buy?
Yes-134011703 is available as an OEM Frigidaire part and as aftermarket versions. OEM parts are made to original specifications and generally provide the most reliable fit and finish.Aftermarket knobs can be less expensive but may vary slightly in fit, colour, or durability. For best results buy a genuine Frigidaire replacement or confirm exact fitment with the seller before purchasing.
What tools and safety precautions do I need to replace the timer knob?
Tools are minimal: frequently enough just your hands to pull on a friction-fit knob; a small screwdriver or hex key if a set screw is present. safety: always disconnect the dryer from power before working on controls,avoid forcing parts (which can break plastic components),and ensure the replacement knob matches the spline pattern. If you must access internal components, follow service manual instructions and consider professional service if you are not comfortable with electrical work.
Where can I buy the 134011703 knob and how do I verify I bought the correct item?
You can purchase the 134011703 from Frigidaire parts dealers, major appliance parts websites, authorized service centers, or reputable online marketplaces. To verify you bought the correct knob, cross-check the seller’s compatibility list with your dryer model number, compare pictures and spline pattern to your current knob, and confirm return policies in case the part doesn’t fit.
