Function and Role of the Washer Switch in â¤Frigidaire âControl Systems
134399700 âFrigidaire Washer⣠Switch functions as the cycle-selector and signal-routing device between the user controlâ interface and⢠the⢠washer’s control circuitry. The switch is typically a multi-pole, multi-position assembly with a cam or detent mechanism that changes which contact sets are closed as â¤the operator â˘rotates the shaft. âIn âpractice it provides discrete electrical paths that âenergize timers, motor relays, water â˘valvesand option circuits; toâ be a direct replacement it âmust âmatch the âoriginal terminal layout, contact âconfigurationand voltage/current ratings soâ that âplug-in harnesses and âchassisâ mounting remain compatible.
Operational behavior of â¤the switch is deterministic: each shaft position corresponds âto a defined combination of closed contacts that initiate â¤specific steps⣠inâ the wash âsequence. common diagnostic signs of a failing switch include intermittent⢠or missing cycle steps, inability toâ select or change â˘cyclesand inconsistent â˘continuity across contact sets.⢠Technicians test theâ part by referencing the service schematic, checking â˘for continuity and correct switching behavior across positions with⤠a⤠multimeterand verifying âsupplyâ voltage at the input terminal⢠when the⣠knob⤠is rotated; if contact â¤resistance âor contact bounce is observed, replacement with the correctly specified unit is ârequired.
- Primary functions: route power to âcontrol âcomponents, provide position feedback to the timer/controland âselect option circuits.
- Typicalâ failure symptoms:â intermittent âŁoperation, no responseâ in certain âpositionsor erratic cycle progression.
- Practical tests: continuity checks per â˘position, voltageâ presence at input,⤠and â¤visual inspection âŁof terminals/mounting.

How the 134399700 â˘Frigidaire Washer Switch Works Inside âthe Appliance
The 134399700 Frigidaire Washer Switch is a multi-contact âŁelectrical switch âmounted in the â¤machine’s control assembly that routes mains and low-voltage signals to drive circuits as the user selects cycles or as mechanical linkages move the selector. Internally â˘it contains one⢠or more sets of metal contacts that âopen and âclose in â¤defined sequences; âeach âŁswitch position⣠connects a specificâ setâ of terminals to provide power toâ the timer, motor windings,â water valvesor pump.in practical⤠operation theâ switch functions as a deterministic routing device: rotating or actuating the control lever changes whichâ contacts are closed,⢠and those closed contacts present continuity to downstream components, enabling discrete functions suchâ as fill, agitate, drainor spin depending on the wiring schematic â¤of theâ model.
- Common â˘observable failures: intermittent or no continuity in â¤certain positions, visible pitting or corrosion⢠on contact surfaces, overheating discolorationandâ loose âor broken spade terminals.
- Typical⢠tests:⣠measure continuity between⢠common and position⣠terminals âwith a multimeter while moving the actuator; inspect for mechanical âŁplay â¤and secure attachment to theâ console or linkage.
- Compatibility notes:â replacement mustâ match terminal layout, actuator geometryand âmounting points-electrical compatibility requires matching the washer model wiringâ diagram rather than assuming identical-looking switches are interchangeable.

Common failure⣠Symptoms and Diagnostic Indicators of the washer Switch
Theâ 134399700 Frigidaire Washer Switch is an âelectromechanical selector that routes power and signals to the â¤washer’s motors, pumpandâ control⣠circuits âŁaccording to the selected cycle. In service âit behaves â¤as âa set âŁofâ discrete contact banks: when the knob⣠or actuatorâ changes position, specific sets of âterminals close to complete circuits forâ agitation, spin, âwater valvesor timers. âfailures typically manifest as worn or pitted contacts, broken internal springsor corroded terminal connectors; replacement requires a switch with the identical terminal layout and detent positions to âremainâ compatible with a given washer model and its wiring harness.
- Intermittent⤠operation â˘or cycles that start and stop⤠unpredictably
- Specific functions (agitate, spinor drain) not engagingâ despite power to the âŁmachine
- Burntâ odor, visible arcingor blackened contact surfaces
- Knob feels loose, slips between âdetentsor does âŁnot click firmly into positions
| Item | Description |
|---|---|
| Continuity (closed) | Low resistance (typicallyâ <10 Ί) between the mapped terminals when the switch is in âthe corresponding⢠position |
| Continuity (open) | Infinite resistance (no continuity) â¤between terminals that should be openâ in⣠a given position |
Diagnosing the switch⢠begins with a visual and âmechanical inspection followed â¤by electrical testing: remove âŁpower, access the switch terminals,â and use a multimeter âŁset to continuity or low-ohms to verify each contact bank in every âselector âposition. Perform⣠a wiggle test while monitoring continuity to reveal intermittent internal breaks; if a circuit shows open when it should be âŁclosedor if resistance⢠is considerably higher than expected under load, the switch is a likely fault. âŁIn practice, confirming correct terminal-to-function mapping against the âwasher’s wiring â¤diagram prevents misdiagnosis – for example,⢠a no-spin symptomâ that⢠shows⤠proper⣠continuity at theâ switch â˘but no voltage at âthe⣠motor points to wiring or motor fault⣠rather âthan⣠the switch itself.
Replacement considerations,Model Compatibility,and Installation âProcedure⣠for the Washerâ Switch
The 134399700 Frigidaire Washer Switch âis a multiâposition control⤠switch used to route lowâvoltage signals and mains power to the washer’s motor,timers,and â˘valves.â Functionally it provides discrete contact closures âfor âŁeach selected cycle state; worn or âpitted contacts can âcause intermittent operation, âŁfailure to startor incorrect cycle selection. Technicians confirm switch behavior by measuring⢠continuity or resistance across terminalsâ in each selector position andâ by visually âŁinspecting contact faces and the terminal âŁblock for corrosion or melted âŁplastic.â In âŁmany frigidaire models this switch is â¤a direct mechanical âinterface between the userâ control and theâ appliance electronics, so mechanical wear (loose detents,⤠broken â˘mounting tabs) can produce symptoms similar to electrical âfaults.
For replacement and installation, first disconnect power and document⤠the wiring harness orientation andâ terminal â¤markings before removal â˘to prevent miswiring. Verifyâ the replacement matches theâ original in pinâout âand mounting geometry; identical external appearance âdoes not guarantee âŁidentical internal contact mapping, so compare continuity⤠patterns or the service parts list.⣠During installation, ensure terminals seat fully, routing does not pinchâ wires against the cabinet, âand â¤fasteners are⣠snug but not overâtorqued;â use a small âamount of⢠dielectric grease on spade terminals if corrosion âŁwas present.After â˘reassembly, ârun a short diagnostic or a single cycle to confirm that each position produces the expected contacts and that related components â¤(motor, lidâ switch, timer) respond correctly.
- Typical â˘checks: continuity per âselector position, visual contact inspection,⢠verify mounting tabs⣠and⤠harness connector match.
- Common symptoms indicating replacement: no start, intermittent cycles, incorrect spin/agitation⣠selection.
- installation tips:⣠label wires, test before final⣠reassembly, avoid bending terminal blades excessively.
