134803600â Frigidaire Washer Timer is an âelectromechanical controlâ assembly used to sequence and time the primary operations of frigidaire washing machines.As a rotaryâ cam timer driven by âŁa small synchronous orâ shaded-pole⢠motor, it contains⢠a set ofâ switch contacts and cams that route power â˘to various subsystems according⤠to the selected cycleâ and elapsed time.
Inside the appliance the timer functions âas the â¤central sequencing device that connects and disconnects line voltage to components such as the wash⢠motor, spin motor or transmission, water inlet valve, drain pumpand âassociated interlocks (such as lid or door switches and pressure/level controls).â It therefore interfaces directly with both power and control circuits and governs â¤transitions between fill,agitate,drain,rinse,and⤠spin operations; its mechanical cams and contact âbanks determine timing,dwell periods and the order⤠in which subsystems are⣠energized.
In this âarticle technicians,â engineersand appliance owners will find a practical examination of the 134803600 timer: how it is indeed constructed and how it⣠functions within the machine, which washer models and wiring layouts it commonly fits, typical failure symptoms (such as failure to advance, stuck cycles, intermittent contactsor loss of functions like spin or drain), basic diagnostic checks to isolate timer faults versus wiring or accessory component failuresand⢠considerations when replacing the unit (matching part numbers and connector layoutsorientation, safety precautionsand⢠simple calibration checks). The intent⢠is to provide âŁtechnical context and troubleshooting direction to support accurate diagnosis and safeâ replacement decisions.

Functional Role and Electrical Interfaces of the Washer Timer Module
The 134803600 Frigidaire Washer Timer functions âas the sequencing controller for mechanical-style Frigidaire washers by timing and routing AC power to the motor,water inlet valves,drain⢠pump,and other load circuits. Internally it⣠is âtypically a small synchronous motor driving a âcam-and-switch assembly (or a compact electronic switch pack in later variants) that closes specific circuits at defined âdrum positions to enforce âwash, rinse,⢠spinand drain intervals. In practical repair⣠work the timer behaves as the system’s hardwired “program,” so failures present⢠as stuck cycles, non-advancing timersorâ intermittent energizing of⢠loads; replacing the module requires a â˘direct match of mounting, terminalâ layoutand electricalâ ratings to â¤the washer model to ensure correct sequencing and safe operation.
- Line input: single-phase AC feed â˘(commonly 120 VAC in North âAmerican models).
- Drive interface: small synchronous motor input âthat⣠advances the cam/switch pack.
- Switched outputs: multiple spade terminals thatâ deliver line or neutral âto pump, âvalves, motor, heater,â etc.
- Ground andâ common/neutral reference points for load circuits.
| Item | Description |
|---|---|
| Nominal Voltage | Typically 120 VACâ line input âfor North⣠American frigidaire washers |
| Connector Type | Male spade terminals / inline wiring harness; terminal layout must match replacement part |
| Typical Fault Modes | Worn switch contacts, failed drive⢠motor, âŁbroken cam, intermittent opens under load |
Electrically,â technicians diagnose timer-related â˘faults by verifying line presence at the incoming terminal and then checking each switched output âas the timer advances; â˘a multimeter or AC voltmeter â¤should show line voltage onâ the output terminal only during its intended cycle position. Practical examples: if the washer never drains while the timer knob indicates the drain step, measure for 120 VAC at the pump âŁterminal during that step – absence ofâ voltage points to a failed timer contact or broken cam linkage, whereas presence of voltage with no pump operation indicatesâ a pump fault. For⣠safe, reliable⤠replacements record⣠wire positions or⤠photograph the harness, match the 134803600 Frigidaire Washer Timer â¤terminal mappingand confirm â¤continuity across cam-operated contacts âand âthe timer drive âmotor before⤠reassembly.
How the 134803600 Frigidaire Washer timer Controls âŁCycle Sequences and Interfaces with Motors, Valvesand Sensors
The 134803600 Frigidaire Washer Timer is anâ electromechanical sequencer that uses a small synchronous motor to advance a âcam-operated switch⢠bank through the programmed cycle positions. As the cam pack ârotates, discrete contact sets close âand open to route line voltage and âcontrol signals to the washer’s subsystems: water inlet valves⣠during fill, â¤the drive motor during agitation andâ spin,â the drain pump during drainingand interlocks such as the lid â˘switch and pressure (water-level) âswitch. This mechanical sequencing means the timer itself does not⤠sense water level or temperature directly; it coordinates power distribution so those sensors and switches can break or complete circuits at the correct times (forâ exmaple, â˘energizing the cold or hot valve⣠until the pressure switch opens to indicate a full tub).
- Motor drive (agitate, spin) – supplies correct windings or speeds â¤for each interval
- Water inlet valve(s) – routes⣠mains power to fill hot/cold as required
- Drain pump – suppliesâ power during drainâ cycles
- Lid/door interlock⣠and pressure switch – permits or interrupts motor/valve power
- Optional heaterâ or temperature control circuits on models that include them
| Item | Description |
|---|---|
| Drive mechanism | Synchronous motor with âcam-drivenâ switch pack |
| Switch type | Multi-position cam⤠switches that route 120 VAC â(North American models) to outputs |
| Typical supply | 120 âVAC, â˘50/60 Hz âŁdependingâ on market; verify model⤠specification |
| Common failures | Worn cam lobes⤠or burned⤠contacts leading to skipped steps, failure to advanceor intermittent circuits |
Technicians commonly troubleshoot the timer by observing⣠cam movement âwhileâ the machine is running and verifying continuity between terminal pairs at⣠different timer positions with a multimeter. Practical diagnostics include verifying the timerâ motor receives mains voltage (if â˘the motor does not turn, the sequencer will not advance), checking for continuity across contact âŁsets that should âŁbe⣠closed in a⣠given cycleand inspecting for mechanical wear or broken gear teeth. When replacing the unit, match âthe 134803600 Frigidaire Washer Timer âpart number to the appliance model and⢠confirm terminal⣠labeling âand âharness compatibility; incorrect substitutions can require rewiring or may not âŁreplicate interlock behavior, leading to unsafe or nonfunctional âŁcycles.
common Failure Symptoms and Diagnostic Indicators: No-Advance, Erratic Timing, âand Electrical Continuity Faults
The â¤134803600 Frigidaireâ Washer Timer is an electromechanical sequencing device that â˘provides timed switching for the âwash motor, water valve, drain pumpand heater â¤circuits. Inside the⤠assembly a⤠small synchronous motor drivesâ a⣠cam stack or wafer contacts that âŁopen and close discrete circuits at predetermined positions.Mechanical wear, a seized motoror pitted/burned contact surfaces will prevent âthe timer from advancing âor will produce intermittent switching; compatibilityâ is typically â¤limited to Frigidaire models designed for this specific part⤠number and wiring configuration, so correct identification of the harness and â˘terminal layout is essential before replacement.
Technicians isolate three classes of faults: no-advance â˘(timer motor notâ turning), âerratic timing (contacts bouncing or sticking)and electrical continuity faults (open âor â˘high-resistance âcircuits through the timer).â Diagnostic steps include verifying presence⣠of 120 VAC at the timer motor lead duringâ a run cycle,measuring the motor coil âŁresistance (typical synchronous motor coils show low âŁohm values),and checking continuity across switching terminals in âmultiple⢠timer positions with a multimeter; visual inspection for âpitted contacts or carbon tracks frequently enough correlates with intermittent symptoms. Common observable symptoms and â˘swift checks are⤠summarized below.
- No-advance: motorâ receives voltage but does not rotate – check motor coil resistance and for mechanical obstruction.
- Erratic timing: washer jumps stages or cycles unpredictably â¤- inspect contact surfaces and â¤measure continuity while rotating the cam.
- Continuity faults: specific functions do ânot energize in any position⤠– traceâ wiring and test continuity â˘across the timer’s⢠switch terminals in corresponding positions.
| Item | Description |
|---|---|
| Expected motor voltage | 120 VAC applied to the timer motor â¤during active advance |
| Motor coil resistance | Low ohms; open or very high resistance indicates a failed motor |
| Contact âcondition | pitted or carbonized contacts cause high-resistance â˘and intermittent switching |
Replacement Considerations, model Compatibilityand Installation Best Practices for the 134803600 Timer
The 134803600 Frigidaire Washer Timer is a cam-operated⣠sequencing device that routes power to the washer’s drive motor, water valves, âpump and other timed functions by closing and opening internal contacts as â¤the central shaft rotates. When replacing this timer, technicians⤠should compare the physical mounting, shaft diameter and splineand the electrical connector pinout rather âthan ârelying solely on âpart numbers; two timers may share a⤠housing but âhave âdifferent cam profiles or contact arrangements that change cycle behavior. For example, installing a timer with a different cam profile can start the spin before the drain motor is energized,⤠creating âa mechanical conflict or incomplete drain⤠– confirming shaft position, contact layout and voltage rating before installation â¤avoids those failures.
- Verifyâ model number âand harness compatibility – match connector⢠count and pin arrangementâ to the original timer.
- Check shaftâ diameter/spline and mounting âhole âpattern âto ensureâ proper mechanical engagement and knob indexing.
- Confirm voltage rating and contact arrangement to âmatch⣠motor, pump and valve circuits.
- Inspect cam profile or service documentation to ensure âidentical cycle sequencing.
Proper installation practice reduces repeat service âcalls: disconnect mains power, photograph the original wiring and knob positionand label âŁharnesses before removal so the⢠same circuits are reconnected. Set the timer to its “park” âor off position before removing,â avoid forcing the shaft or gearsand use a multimeter to verify â¤continuity through each contact position during preliminary â˘bench testing; after installation, run a full diagnostic or an âŁempty timed cycle to verify âcorrect valve, motor and pump operation⢠without load.If contacts show pitting or intermittent continuity on the removed unit,â replace â¤rather than re-lube; when reconnecting, ensure good mechanicalâ ground and secure, corrosion-free connections.
| Item | Description |
|---|---|
| Shaft/Spline | diameter and spline count determine â˘mechanical fit with knobâ and gear train. |
| Connector Pinout | Number and function of pins must match harness to route power⤠correctly to motor, pump and valves. |
| Voltage/Contact Rating | Contacts must⢠be⤠rated for the applianceâ supply voltage and expected motor/pump currents. |
| Cam Profile | Defines cycle sequencing;⣠mismatched profiles alter the order/timingâ of operations. |
Q&A
What âis the 134803600 Frigidaire washer timer?
The â134803600⤠is âan OEM electromechanical timer assembly â¤used as the cycle controller on certain Frigidaire washing machines.It switches power to the washer’s components (fill valve, â˘motor, pump, etc.) according â¤to the selected cycle camsâ and contact positions.It is a mechanical/electrical âswitching device rather than a modern electronicâ control board.
How do I âknow if the 134803600 timer is failing?
Common symptoms of a failing timer⣠include: the washer getting stuck⣠in one cycle or â¤not advancing,intermittent âŁor noâ power to⣠the â¤motor/fill/pump during⣠cycles,the washer not starting,audible clicking,or visible burned contacts âon theâ timer. Because other parts (lidâ switch, drive motor, selector switch, wiring) can cause similar problems, â¤confirm the timer is the source before replacement.
How can a technician testâ the⢠134803600 timer to determine if it is indeed bad?
With the washer unplugged, remove the control panel to access the timer and consult the â˘wiring diagram. Use a multimeter â˘to check continuity between âthe âŁtimer’s common terminal and the cycle output terminals while rotating the timer cam or switching through cycle⢠positions.With the machine energized (use caution),measure for line voltage at the âtimer’s output terminals during theâ corresponding cycle steps. loss of continuityâ where the timer âshould be closed or no âoutput⤠voltage when expected indicates a faulty timer.
what safety steps should I follow when testing or replacing the timer?
Always unplug the washer before opening the cabinet. If you must measure live voltages, only do so if you are⤠agreeable and experienced â¤with mains electricity; useâ insulated tools âand keep one hand away from exposed live parts. Label or photograph wiring before disconnectingand discharge any capacitors (if present). if âunsure, hire a qualified appliance technician.
How do I replace the 134803600 timer (basic procedure and time⣠estimate)?
Basic replacement steps: unplug the washer, remove the control knob and controlâ panel or back â¤console âto access the timer, photograph/label all wire connections, unplug the wiring harnesses, remove the mounting â˘screws âand take out the timer, install the new timer and reconnect the harnesses exactly as before, reassemble âŁand âtest with a short cycle. A competent DIYer can typically do this in 30-90 minutes; âŁa professional⣠can do it â¤faster.
is the 134803600 timer compatible with other Frigidaire model numbers or âpart replacements?
Compatibility depends on the specific washer â¤model. Do not assume interchangeability solely âby appearance. Confirm compatibility by⤠checking the washer’s model⤠number against the â¤part list or manufacturer parts diagram.Many parts suppliers and Frigidaire’s parts â¤lookup will show cross-reference or superseded âpart numbers if applicable.
How much does a 134803600 timer cost and where can Iâ buy one?
Price varies â˘by seller and âŁwhether the part is new OEM, aftermarketor⢠used. âExpect a wide ârange (commonlyâ in the tens to low hundreds of dollars). Buy from authorized Frigidaire parts dealers,reputable online appliance parts stores,or local appliance parts⤠suppliers. Avoid very cheap unknown substitutes; verify return policy and warranty.
Any troubleshooting tips before replacingâ the timer?
Check simpler/cheaperâ items first: verify the lid switch, â˘drive⢠motor, motor capacitor (if applicable), door latch, selector⤠knoband⤠wiring for continuity and proper operation. Inspect the⤠timer for visible burns⢠or melted plastic.⤠Sometimes a poor wire âconnection, a bad lid âŁswitchor a failed motor is mistaken for a bad âŁtimer. If the timer motor (the small motor that advances the cams) isn’t advancing but the timer contacts look intact, the timer motor alone may be at fault.
