134803600 Frigidaire Washer Timer is an electromechanical cycle-timing assembly used to sequence andâ control the major functionsâ of compatible Frigidaire washing â˘machines. âThe â¤component typically combines a synchronous drive â˘motor, âa⢠cam-operated switch pack, âand a timingâ mechanism housed behind the machine’s âcontrol panel; together these â¤elements open and close electrical â¤circuits to initiate and terminate wash,⤠rinse, drainand spin operations⢠according to the selected cycle.
Inside the appliance, the timer â˘acts as the central timing âand routingâ element that coordinates inputs from user⤠controls and safetyâ interlocks (for example, lid or door switches) with outputs to actuators such as the water inlet valve, drive motor, drain pumpand⤠clutch or brake. The switch âcontacts and cam profile withinâ the timer determine whichâ circuits receive⤠power at specific points in the cycleand the timerâ motor provides the indexing motionâ that advances the program. Because it â¤interfaces directly with both control and power circuits, the timer’s behaviour affects electrical continuity, sequencing reliabilityand the â˘interaction of mechanical⤠subsystems during operation.
In âthis article readers will find a technical overview âof how the 134803600 timer functions, guidance on modelâ compatibility âand⢠identification,⣠common failure symptoms and diagnostic âchecks, practical⣠troubleshooting steps (including continuity and voltage tests)and considerations⤠for safe â¤replacement or ârepair. The coverage emphasizes â¤systematic fault isolation-distinguishing timer faults from âŁrelated issues such as âŁmotor,switch,or⤠harness â¤failures-and outlines mechanical and electrical replacement considerations technicians âand owners should account for when restoring correct cycle âsequencing.

Function⤠and Role of theâ Timer Assembly in Frigidaire Washing Machines
The 134803600 Frigidaireâ Washer Timerâ is an electromechanical rotary⤠cam assembly that sequences the âwasher’s electrical circuits by mechanically operating multiple switch â¤contacts. A small synchronous drive motor turns a cam stack and gear train to provide timed contact closures that route mains voltage to the drive â˘motor, water valve, drain pump,⤠and âany auxiliaryâ devices.â In practice⤠this module defines the duration and order of fill, agitation, drainand spin phases; a failed timer⤠typically manifests as a âmachine that â˘will not âadvance between phases, repeats⢠the same actionor âpowers the wrong componentâ at the wrong time.
Theâ timer behaves as a logic sequencer rather than⢠a sensor:â each cam position â˘corresponds to a set ofâ closed and open contacts that determineâ which subsystemsâ receive âŁpower. âtechnicians verify timerâ function by checking⤠continuity across âŁcam-operated contacts in successive indexed positions and by âŁconfirming⢠the drive motor receives theâ proper supply to advance the cams. For compatibility,⢠match the 134803600 part number, mounting pointsand wiring harness terminals to the washer’s schematic before replacement; on the bench, apply mains power only to the âtimer motor for indexing tests and avoid⤠energizing switched outputs unless theâ assemblyâ is⤠installed to prevent accidental motor or⣠heater â¤activation.
- Common symptoms: failure to advance cycles,⣠intermittent operation, stuck onâ a âsingle phaseor⣠burnt contactâ evidence.
- Quick diagnosticâ checks: verify motor index pulse, measure continuity across cam follower switches, inspect for corrosion or broken gears.
- Replacement considerations: âconfirmâ harness pinout and mounting studâ alignment to âensure correctâ mechanical â˘indexing and âŁelectrical connections.

how the 134803600 frigidaire⢠Washer Timer Interfaces âwith Drive, Valve âand Control Circuits
The⣠134803600 â˘Frigidaire Washerâ Timer is a â¤mechanically driven ârotary switch that sequences powerâ to the washer’s drive motor, water inlet valves âand control circuits by opening and closing groups of âŁcontacts as the internal cam pack advances. âThe timer âŁuses a âŁsmall synchronous motor⤠and gear train to â¤step through discrete âŁpositions; each positionâ routes line voltage and neutral to specific â˘terminals that â˘energize â˘the drive motor, fill solenoids, drain âpump and any interlock circuits. In practice this means the timer does âŁnot âcommandâ voltages like a microcontroller but rather provides formâA and formâC contact closures that distribute mains power to downstream devices and â˘to sensing/feedback circuits (e.g., lid switch, pressure switch) to complete⤠the âŁoperational loops required for a given cycle step.
The practical behavior and compatibility of the timer â¤depend on terminal layout, â¤contact condition andâ motor speed.⣠Worn or pitted contacts produce intermittent operation of âvalves or drive, while a stalled⢠timer motor âwillâ freeze the machine in a single state. Technicians should verify expected voltages at the timer terminals during known cycle steps (for example: valve voltage present⣠during fill, â¤drive motor voltage⤠during agitate/spinand pump voltage during â˘drain) and compare against the reference terminal map for⢠the â˘replacement part.⤠For field troubleshooting and replacement selection, ensure the â¤substitute matches the original terminal numbering, contact groupings and motor RPM; mismatches can result⢠in wrong⣠sequencingâ or incompatible⣠load switching.
- Common interface âpoints: drive motor output, water âinlet solenoid outputs,⢠pump/drain âoutput, neutral/common bus, interlock/door âŁand pressure switch feeds.
- Behavioral⣠cues: intermittent contactâ = erratic valve/drive behavior;⤠slowâ motor⢠= delayed âŁor skipped steps.
- Compatibility check: confirmâ terminal arrangement and drive â¤motor speed with the service spec before installing a replacement.

Common Failure âŁSymptoms and Electrical/Mechanical Diagnostic â˘Indicators
The ⢠134803600 âFrigidaire Washer Timer is a cam-driven sequence controller that routes mains âvoltage to the motor, water valvesand pump according to âthe programmed cycle. Electrically, the timerâ contains⣠multiple switch âŁcontacts and a lowâtorque synchronous motor; mechanically, â¤it uses gears âand⢠cams to position those contacts.Failures commonly âarise â˘fromâ contact⢠pitting or⢠burning, wornâ cam lobes or gear teethand a weakenedâ or⣠seized timer motor; compatibility âproblems⤠occur when a timer withâ a different cam profile⢠or terminal layout is fitted, producing incorrect âsequencingâ even though the part âfits mechanically.
- No cycle advancement â¤or stuck on one âfunction (fill, washor drain)
- Erratic âtiming or skipped steps during cycle progression
- Burnt smell, visible â˘pitting on switch contactsor a â˘nonârotating timer dial
Diagnosing âthe⢠timer requires both⢠electrical checks and mechanical inspection.⤠Measure âforâ continuity across the individual cam â˘switch terminals in different dial positions⣠and verify that the timerâ motor receives the appropriate supply voltage when the washerâ should advance; an open âwinding or zero input voltage pinpoints âŁan electrical failure or upstream wiring/control âŁfault. â˘Mechanically, rotate the âtimer shaft by hand â(with power⣠off) to feel for binding,⤠roughnessor backlash in the gear train-if the dial won’t advance under power but the motor is energised, expect âa seizedâ bushing,⢠stripped gearor broken cam pawl.Practical troubleshooting examples: if the washer fills and drains but never agitates, check theâ agitation contact â¤path â¤on the timerâ and the corresponding terminal for⢠continuity; if the timer⤠dial is dead and there is noâ input to the timer motor, trace supply back â˘to the selector switch âŁor⣠main⣠control harness before replacing âthe timer.
| Item | Description |
|---|---|
| No â¤cycle advance | Timer motor not receiving supplyâ or seized âgear/train-verify voltage at motor and attemptâ manual shaft rotation. |
| Intermittent or skipped steps | Pitted/burnt contacts orâ loose terminal connections-inspect contact⢠surfaces and measure continuity across switch positions. |
| Correct fit but wrong âbehavior | Mismatched cam profile or terminal layout-confirm OEM part number and terminal âmapping before substitution. |
Compatibility, âReplacement Considerationsand StepâbyâStep Installation and Troubleshooting Procedures
The 134803600⣠Frigidaire Washer Timer isâ an electromechanical â¤rotary âŁtimer that sequences âthe washer’s âfunctions by advancing âa cam stack that opens andâ closes internal âŁswitches and âroutes power to the drain pump, water âvalve, motorandâ centrifugal switch at the⤠correct â˘times. The timer typically contains a small synchronous motor âdriving⢠gears and cams;⢠visible symptoms of timer â¤degradation include failure to advance âto the âŁnext cycle, intermittent contact closure, audible âclicking without step advancementor burned contacts. Compatibility depends on âphysical mounting, shaft length and spline, connector type and pinoutand the schematic for the specific washer⢠model; replacing with âŁa visually similar â¤timer without confirming⢠these parameters can⢠result in⣠incorrect⣠wiring or inability to âŁsecure the part. âConfirm the part number against the washer’s wiring diagram, check that âthe â¤harness â˘connectors matchand â¤compare shaft â˘orientation⢠and mounting holes before⢠installing a âreplacement.
Replacement âand troubleshooting follow methodicalâ electrical and⢠mechanicalâ checks: first,â disconnect âmains power and document wire locations with photosâ or labels, then remove the control âpanel and retainingâ hardware to â˘access the timer.Use âa multimeter to measure continuity across the timer’s switch contacts and resistance of the timer motor (an â¤open motor winding indicates failure); with power reapplied⤠for live tests, verify the⤠timer motor receives its expected âline⣠voltage during âan advancing âevent (use insulated probes and caution). When â˘installing a⣠replacement, align the timerâ to the â˘correct dwell/cycle position before fastening, secure the harness⣠without forcing connectorsand verify operation through âa full â˘drain-wash-spin sequence. Ifâ intermittent â¤behavior persists after replacement, inspect wiring for chafing, âtest downstream components (motor, pump, âvalves) for âfaultsâ that canâ load the â¤timerand âclean or replace corroded connectorsâ rather⤠than splicing as a permanent⤠fix.

Q&A
What is Frigidaire part 134803600 and what âŁdoes the washer timer do?
Frigidaire part 134803600 is the electromechanical cycle timer used on certain Frigidaire/whiteâgoods topâload washers.⢠The timer sequences the washer’s operations by switching power to theâ fill valve, agitate â¤motor, drain pump andâ spin⢠circuits in the correct order and for the⢠correct durations. It âcontains a âŁsmall synchronous motor and a set of⢠cams/switches or contact assemblies that open and close as the dial advances.
What are the â¤common symptoms that the 134803600 timer is failing?
Typicalâ signs of a bad timer include: the âŁwasher won’t advance through cyclesâ (stays inâ one âposition), it won’t start or complete a cycle, no⣠agitation or no spin â˘while other functions work, erratic or intermittent operation, âburning smell or visible melted âŁplastic around âthe âtimer,⣠or⢠the timer dial â¤won’t turn.â Note thatâ some of these symptoms can⣠also be caused by âother components (lid switch, motor coupling,â drive motor,⤠wiring), so proper diagnosis â˘isâ vital.
How can I⢠test whether the⣠timer is faulty?
Startâ with a visual inspectionâ for burned contacts, melted plastic or âbroken gears. â¤Safelyâ check for incoming powerâ to the⤠timer while â˘a cycle is selected (use a⣠multimeter and follow lockout⢠power âprocedures). Test continuity of theâ timer motor âŁand the individual switches/contacts âwith the timer removed from âthe âwasher. A⤠timer motor that has â¤no continuity or a set of⢠contacts â˘that don’t âchange continuity as the cam is rotated indicates a bad âtimer. Because the timer⣠switches are âelectromechanical, intermittentâ contacts can also be diagnosed by wiggling the shaft while measuring. If you’re not agreeable âworking⢠with live circuits, haveâ a qualified technician perform the electricalâ tests.
Can I replace just the â¤motor⣠inside the timer or do I need to replace the âŁwhole â134803600 assembly?
It depends on the exact timer⤠design and parts availability. Some timersâ have replaceable synchronous⤠motors that can be purchased separately, âwhile others are sold only as the âentire â˘timer assembly. Inâ many cases it’s easier and more reliable to replace the⣠entire timer assembly. Check theâ partsâ diagram âŁfor your washer model or contact âa parts⣠supplier to see whether a motor replacement is available for 134803600.
Is part 134803600 compatibleâ with my washer model?
Compatibilityâ is determined âŁby your washer’s â¤model number. Search the âmodel numberâ against⢠OEM parts lists or⢠the Frigidaire parts databaseâ to confirmâ that 134803600 fits. Don’t assume compatibility by âlooking at photos alone; wiring harnesses and mounting points can differ â˘betweenâ models. If⢠in doubt, provide the washer model number to a parts dealer âorâ look up the OEMâ crossâreference.
How difficult is it to replace â¤theâ 134803600 timer and what should I be⢠careful about?
Replacing the timer isâ generally a moderate DIY âjob for someone with basic appliance repair skills. âTypical steps: unplug the washer, âremove the control console or⢠timer retaining â˘screws, note or photograph all wire â˘connections⢠andâ harness locations, disconnectâ wires from the old timer, install and secure the new timer, reconnect âwires exactly as they â¤were,⢠and test the machine.⣠Key cautions: alwaysâ disconnect powerâ before starting, label or photograph wiring to avoid miswiringand don’t run the washer with exposed live terminals. If you’re uncomfortable with electrical components,â hire a technician.
How muchâ does a 134803600 timerâ cost and where can I buy one?
Price varies â˘by source and whether the part is OEM or aftermarket. Expect â˘the timer assembly to range â˘roughlyâ fromâ about $40 to $150, though prices can⣠be higher for OEM or hardâtoâfind parts. Purchaseâ from authorized Frigidaire âparts dealers, appliance parts retailersor reputable online marketplaces. Factor in additional labor cost âif you hire a technician for the âreplacement.
Are âthere âany repairsâ I can try before replacing the timer?
Yes-some intermittent timer problems can be resolved without full replacement. Try cleaning corroded or dirty electrical contacts with a â¤contactâ cleaner, checking and tightening loose âwiring connectionsand lubricating any worn plasticâ gears â(only if accessible and recommended by the manufacturer). âAlso ruleâ out âother components that mimicâ timer failure-test the lid switch, drive âmotor, motor coupling, beltsand âfuses/thermal cutouts-because replacing the timer â¤won’t fix failures in âthose parts. If cleaning and minor repairsâ don’t âcure the â¤problem, the timer assembly usually needs replacement.
