131758600 Frigidaire Control Timer is a time-based control module â˘used to sequence âŁand time the major functions of a household appliance. It is indeed a control timer assembly-implemented in some⣠models as a mechanical cam-driven âswitchpack or⢠as an electronic timing board-that providesâ timed switching â¤outputs to⢠the appliance’s power âcircuits and user-selected â˘program steps.
Inside the appliance the control⤠timer coordinates the âŁoperation⤠of subsystems âsuch as the drive motor,â water inlet valves, drain pump, heating element, âdispenser, âdoorâ latchand associated sensors. It receives user inputs from the selector or console, monitors limit and sensor signalsand switches power to actuators in a prescribed order to complete wash, â˘rinse, drainor âdry⣠cycles. Technicallyâ itâ functionsâ as âaâ sequencer and power distribution interface and is integrated into the main⢠wiring harness and⢠control chain, so its behavior affects both electrical load switching â˘and overall program timing.

function and Role âofâ the Control Timer in Frigidaire Appliances
The 131758600 Frigidaire Control Timer is a timing and sequencing module used to orchestrate â˘the electrical events of an⣠appliance cycle. Internally⤠it advances a⤠cam or electronic stepper to close and â˘openâ contact sets that supply mains-level⢠power to motors, heaters, solenoid âvalves and indicator circuits⢠on âŁa timed schedule. Functionally the⢠timer acts as the â¤centralâ state machine âŁthat â¤translates the user-selected â˘program into a sequence of switched outputs and interlocks; such as, during a wash cycle it will control fill â¤duration, agitation intervals, drain andâ spin timing, while coordinating inputs from âdoor switches,â water level sensorsor temperature sensorsâ toâ permit or inhibitâ certain transitions.
When the timer malfunctions⢠theâ appliance commonly exhibits failures such as failure to advance between⣠steps, continuous operation in a single stepor loss âof specificâ functions (no water âŁfill, no spin, âno heat).Typical diagnostic checks include⣠verifying line voltage at⣠the timer input, exercising the timer advance manually to observe contact switchingand measuring continuity⤠across output terminals during expected active intervals. Replacement⣠requires matching the part number and terminal layout so wiring and cam positionsâ align with the control âŁscheme; after⤠replacement, verify correct cycle progression and âconfirm any user-programmed offsets âor mechanical⤠detents are set âcorrectly for the applianceâ model.
- Noâ cycle âŁadvance or stuck in one step
- Loss⤠of specific outputs (motor, heater, âvalve)
- Erratic or â˘intermittent operation âcorrelated with contact â˘wear
- Visible corrosion or mechanical failure of advance mechanism

how the 131758600 Frigidaire⢠control Timer Works Inside âthe â¤Appliance
The 131758600â Frigidaire Control Timer is an electromechanical sequencing⤠device thatâ controls the timed switching of motors, â¤valves, heaters and otherâ loads within the â˘appliance. Internally the assembly uses â¤a smallâ synchronous clock motor driving âa cam stack or rotor that⢠actuatesâ a bank of contacts in a defined sequence; those contacts close â˘and⢠open⢠circuits at specific âintervals to advance cycle stages. Technically, the âtimer is a combination of a⤠lowâspeed motor, indexed detentsandâ multiple switch wafers whose⤠wiring and contact configurations must match the appliance harness and schematic for correct operation.
- Mechanical cam/rotor that advances discrete switch wafers
- Synchronous clock motor providing index timing
- Multiple contact banks âfor separate loads⣠(motor, valves, heater)
- Commonâ failure symptoms: stuck or⣠noisy dial, intermittent contacts, no advance
| item | Description |
|---|---|
| motor type | LowâRPM synchronous clock motor that indexes the cam |
| Primaryâ function | sequence power to subsystems by opening/closing contact wafers |
| Common âfailure mode | Worn⢠contacts, stripped âcam âteethor lossâ of motor torque |
In practice, technicians diagnose timer faults by observing whether the dial advances and⤠by performing continuity checks across specific switch terminals while energizing the⢠timer motor; a timer that receives supply â˘voltageâ but does not change state or shows intermittent continuity onâ contact wafers is a likely âcandidate for replacement. âWhen replacing the⤠unit, verify the part⣠number against the appliance model and wiring diagram as correct connectorâ pinout and cam sequencing determine compatibility – swapping a visually similar timer⢠without matching the contact layout can⣠leave functions unpowered or missequenced.
Common Failure Symptoms and Diagnostic⣠Indicators for the Control Timer
The 131758600 Frigidaire Controlâ Timer isâ an electromechanical sequencing device that rotates âa cam stack⤠to open and close multipleâ contact â˘circuits,⢠providing timed power to motors, heating elements, valvesand other loads. Because the unit typically uses â˘a âsynchronous motor driven from the appliance line voltage and mechanical contactors to switch loads, failure modes generally⤠fall into two categories: loss of motor drive (no rotation)â and â¤failure of switching contacts (sticking, pittingor open circuits). Correct âreplacement requires matchingâ the timer’s terminal layout,â camâ profiles and âŁrated⢠voltage so the⣠sequence andâ timing remain compatibleâ with theâ appliance’s control â¤design.
- Intermittent â˘advancement: Timer motor stalls or skips positions, causing âcycles âŁto stop mid-sequence or restart unexpectedly.
- No outputs despite âŁinput power: Line voltage present at the timer’s source â˘terminal but no voltage⤠at the switched terminals (indicates â¤openâ contacts orâ broken cam linkage).
- Stuck or welded contacts: Certain functions remain⣠permanently on or off; visual inspection shows pitted/burned contact âsurfaces.
- Noise without operation: â Motor hums but cam⣠does not advance – suggests mechanical slip â¤or stripped â˘gearing.
| Item | Description |
|---|---|
| Motor continuity | Measure for continuity across the timer motor âŁwinding; an open winding indicates motor failure and no cam advance. |
| Contact switching | With power removed, manually advance âthe camâ and â˘test continuity across⢠switched terminals to⤠confirm contact operation under no-load conditions. |
| Voltage under â˘load | Measure line voltage at the timer output while⢠the circuit is commanded on; presence of voltage confirms â¤driver function, absence with correct command points to contact â¤failure. |
Practical diagnostics start with verifying supplyâ voltage âto the timer, then isolating whether the âŁfault is â˘mechanical or electrical: manually advancing the cam can separate motor-driveâ faults from contact failures, âwhile a bench continuity⢠check or substitution with a known-good unit confirms âswitching integrity. Inspect terminal âconnections and harness compatibility before replacement; swapping to aâ different timer variant⤠withoutâ matching cam âsequencing or terminal mapping can change appliance⢠behavior even ifâ the replacement physically fits.
Compatibility, Replacement Considerations,â and â¤Installation âProcedures for the â131758600â Control Timer
The 131758600 Frigidaire Control Timer serves as the sequencing element in compatibleâ Frigidaire âŁlaundry âappliances, initiating and terminating âŁmotor, heater, valve âand drain â¤circuits on a timed schedule.â Implementations â˘vary between electromechanical rotary cam â˘stacks â¤that actuate multiple switch contacts and stepper-motor-driven electronic âmodules; both require matching âthe physical âmountingâ footprint, shaft orientationand⤠the electrical pinout to the â˘appliance harness. Verify pin-to-function mapping from the service manual or âŁby⤠continuity testing as visually similar housings âcan have different⢠contact â¤assignments or gear ratios that alter cycle timing.
For replacement and installation, first isolate power âand â¤document all wiring positions with photos âand labeled connectors, then remove the⢠controlâ bezel, âknob and retaining fasteners toâ access the timer. Before final assembly,⢠check terminal continuity âŁwhile⣠manually advancing the timer to confirm contact sequencing, secure the timer with correct⢠fastener torque âto prevent âshaftâ bindingand perform a full functionalâ orâ diagnostic âcycle to validate⤠timing and phase behaviors; persistent⣠symptoms such as non-advancing shafts,⤠skipped stepsor incorrect heating intervals often indicateâ eitherâ an incorrect variantâ or a failing drive mechanism rather âthan a simple wiring â¤error.
- Confirm connector countâ and â˘pinout against the âserviceâ schematic.
- match shaft spline and knob orientation to preserve cycle â¤indexing.
- Check supply voltage and common terminalâ labels prior to energizing.
- map âswitch contacts with a multimeter âwhile rotating the shaft to verify sequencing.
- Run a completeâ cycle and â¤record⤠timing deviations forâ troubleshooting.
