functional Role â˘and Electrical⣠Responsibilities âof the Controlâ Timer Module
The 131758600 Frigidaire Control Timer acts as the⤠central sequencing device that times and switches the line-voltage circuits for heating elements, indicator lights,⣠and âŁoven accessories. internally⣠it combines aâ small synchronous motor⣠or âŁelectronic timing module⢠with a set of cam-operated or solid-state âŁcontacts; those contacts carry mains current to the â¤bake⣠and broil elements,â the oven light, â¤and anyâ interlocksâ in the âcorrect order. âIn electrical terms âŁthe timer’s responsibilities are to provide time-based closure of specific power⣠circuits, tolerate âŁthe inrush currents of âresistive loadsand presentâ the correct terminal â˘layout and voltage characteristics so it⣠can be replaced without⣠re-engineering the appliance wiring âŁharness.
- Switching â¤mains loads (bake/broil elements,light) in⣠the proper sequence.
- Providing a stable timing drive (synchronous motor âŁor electronic clock) for repeatable cycle durations.
- Isolating control⤠logic from high-current⢠contacts â˘to protect low-voltage components.
- Matchingâ terminal arrangement and nominal voltage for direct replacement compatibility.
Behaviorally, the module may fail either electrically (open windings, âburned contacts) or⤠mechanically (worn cams,â seized⣠shaft) âand typical symptoms include âelements that do not energize âat â¤expected times, stuck-on cycles,⣠or no timer motor rotation. When replacing or troubleshooting, confirm nominal supply voltage,⢠verify â˘continuity across âthe timer’s switching âcontacts with a âŁmultimeterand â˘compare â¤connector â˘pin⤠assignments to â¤the â˘service diagram; many installations allow direct âswap of the â˘part number but⢠differences in harness orientation or mounting tabs can requireâ adapter hardware.A practical checkâ before replacement âŁis to measure⤠voltage at the timer input⣠to ensure âthe⢠problem is not âupstream (fuse, control âŁboard)and â˘toâ inspect contacts for pitting if the unit has been exposed toâ high-current switching⤠for many years.

Howâ the 131758600 Frigidaire Control Timer Interfaces â¤with Power, Sensors, âŁand Output Relays
Theâ 131758600 âfrigidaire Control Timer is a âŁlow-level⣠control module that ties mains power, sensor inputsand output ârelays⤠into the refrigerator’s⤠timing âand âŁprotection logic.â On âmost⢠Frigidaire refrigerators this board receives aâ line voltage (typicalâ 120 â¤VAC) and uses an internal transformer or âŁswitching regulator to create âthe⣠low-voltage supply for the control⢠electronics and ADCâ inputs.Sensorâ inputs are usually NTC thermistors for the evaporator and â˘cabinet, a door switchand a defrost termination thermostat; those signals are read by the board’s âŁmicrocontroller or comparator circuits âand used to sequenceâ compressor, fan,⤠andâ defrost events.during â¤replacement â˘or diagnostics, confirm âŁconnector pinouts â¤and âharness âcompatibility – the module will not behave correctly if⤠the âpower, neutral, âŁor sensor wires are âmismatched â˘even if theâ physical connector fits.
Outputs are implemented as⤠relay contacts⢠or solid-state âswitchingâ devices that âŁswitch the mains feeds to the âcompressor, evaporator fanand defrost heater; these â˘outputs directly âcarryâ the â˘high-current mains so⣠they must be tested with power removed orâ using appropriate â¤safety procedures.The timer logicâ energizes the compressor relay for⤠cooling cycles, enables the defrost âheater â˘and monitors the â¤thermistorâ to⣠terminate defrostand sequences⤠fan operation âwith⣠appropriate delays to prevent short-cycling. Common field symptoms tied⣠to this module include a compressor that never receives line voltage, âa defrostâ heater that stays energizedor⢠intermittent fan operationâ – âtypical causes include welded ârelay contacts, failed⤠driver componentsor cold⢠solder joints on the board. For practical troubleshooting, verify mains at⢠the power input, measure the low-voltage rail â˘for the⢠control logicand read thermistor resistance⣠at known⢠temperatures to âconfirm âaccurate sensorâ inputs.
- Power input: ⣠Lineâ and neutral (typical⣠120⣠VAC) â¤and internal low-voltage supply for logic.
- Sensor â˘inputs: NTC thermistors, door switch, defrost thermostat.
- Outputs: Compressor relay, defrost heater â¤relay, evaporator/cabinet fan output.
- Common failure modes: welded relay contacts,â failed triacs/driver ICs, connector/harness âfaults.
| Item | Description |
|---|---|
| Power input | Line voltage âŁfeed (typical 120 VAC) âand internal regulator/transformer â¤for control electronics |
| Control supply | Low-voltage DC rail⤠that powers the microcontroller/logic and â˘ADC inputs |
| Sensor âinputs | NTC thermistorsâ and switches read by ADC/comparator to determine timing and âŁdefrost termination |

Common Failure modes and Symptom Patterns â˘Associated withâ Timer Malfunctions
The 131758600 â˘Frigidaireâ Control Timer is âŁan⢠electromechanical timing device that sequences âpower to motors, âŁheaters, valvesand switches by opening and closing contact sets âas a cam â¤or stepper advances. Inâ practice this â˘component behaves â¤as both a clock and a â¤distribution switch: âa small â˘drive motor or a stepping mechanism moves cams that make or break circuits âŁat defined points in a cycle. Compatibility is strictlyâ mechanical⤠and electrical â-⤠correct âreplacement requiresâ matching the pinout, mounting âindexand driveâ orientation since swapped timers with different contact arrangements willâ produce incorrect sequencingâ even if connectors⤠fit. Common wear modes include worn cam detents that âallow slipping, fatigued spring contacts that develop high resistance, gear or âmotor failure that halts advancementand heat-damaged traces or pitted contact â¤surfaces that cause intermittentâ conductivity â¤or arcing â¤under load.
- Cycle fails to advance or stalls⣠at â¤a single step.
- Intermittent⣠operation of⤠components⣠(heater, motor, valve)â during a â¤cycle.
- Short âŁcycles orâ components âŁthat run continuously past expected times.
- Audibleâ grinding or humming from the timer driveâ or visible⤠arcing/burning at contact terminals.
| Item | Description |
|---|---|
| Stuck advance | Drive motor or gear â¤teeth worn; verify âmotor supply and attempt â˘manual advance per service procedure. |
| Intermittent power | Pitted or â¤oxidized contacts producing high resistance; inspect contacts visually and⣠check continuity under load. |
| Continuous⣠or shorted cycles | Stuck contact or bridgedâ terminals from âŁcarbon/soot; â¤isolateâ timerâ outputs and âmeasure for âunintended continuity. |
For field⤠diagnosis, confirm â¤presence of⣠the expected supply atâ the âtimerâ inputâ and than verify output⢠switching⢠as the unit is â¤advanced; use a multimeter to⣠check continuity and measure âŁresistance of⣠the motor or coiland listen forâ mechanical drive ânoise to detect âseized gearing. Practical repair decisions depend on what âfails: corroded or pitted contacts sometimesâ can be cleaned⢠and â˘restoredâ temporarily, â˘while mechanical failures of the drive or broken cam lobes require replacement with a correctly indexed âunit. Always compare the replacement âpart ânumber â¤and wiring schematic âwith the â˘original harness and follow âmanufacturer service procedures to avoidâ mismatched⤠sequencing or unsafe âconnections.
Model Compatibility, Replacement Considerations, Installation Best Practices, âŁand Diagnostic Procedures
The 131758600 Frigidaire Control Timer âŁis a time-driven â˘switching assembly that sequences functionsâ by actuating multiple cam-operated contacts and anâ internal synchronous motor. In operation the⣠timer⤠provides timed â¤power to loads (motors, heaters, valves) and closes open/closed contacts in âa â¤predetermined order; failure modes typically present âŁas âstuckâ positions, intermittent âcontact, âŁor âŁa nonârunning motor. For compatibility, confirm the exact part ânumber,⣠terminal numberingand physical shaft/cam orientation against the appliance⣠wiring diagram and mounting brackets-two timers with similar â¤appearance can have different cam profilesâ or contact assignments, âso crossâreferencing harness connectors and rated supply voltage âisâ required before replacement.
Duringâ replacementâ and âŁdiagnostics follow conservative, evidenceâbased steps: de-energize theâ appliance, labelâ or âphotograph each wire at the timer terminals,â and verify the timer âmotor receives line voltage with the control set to run; then check continuity âacross the contact sets in different cam positions.Typical diagnostic checks include⢠motor⣠stall, âburned⤠contacts, âŁand incorrect⤠cam âtiming; repairs âmay involve replacing the entire timer assembly ratherâ than â¤attempting internal rewiring. For installation,⣠seat the timer fully on its mounting⤠boss, align the shaft/gear âwith the controlâ knoband confirm that all connectors are⤠fully engaged⤠to prevent intermittent⢠faults. The short checklist below outlines⣠practical test pointsâ that â¤help separate â˘timer faults⢠from downstream component â˘failures.
- Confirmâ supply voltage to the timer motor with â˘a âmultimeter while the control is âin a running position.
- Measure âcontinuity across individual contact⤠pairs âas the timer shaft is⢠rotated through cycles.
- Inspect for thermal damage âŁor pitting on contact faces thatâ indicate â˘arcing; replace if present.
- Verify connector pinoutâ and harness compatibility â¤against â˘the appliance⢠schematic before installing the replacement.
