Function and Role of the Control âTimer inâ Frigidaire⣠Appliances
The 131758600â Frigidaire Control Timer is an⤠electromechanical timing assembly that sequences⢠power to an appliance’s subsystems by⢠mechanically⣠actuating â¤aâ bank of switches⢠as its internal⢠motor advances cams.In âpractical terms, the⣠timer provides timed closures andâ openings âŁfor loads suchâ as heatingâ elements, blowers, defrost circuitsor âcompressors depending on the âappliance type. Its behavior â˘is defined by the cam profile and switch map inside â¤the housing: as the motor turns the camshaft, discreteâ switches close or open at predetermined⣠positions to start â¤or stop specific functions.â technicians should â¤verify physical fit, âconnector typeand cam indexing when assessingâ compatibility, as different Frigidaire models can use â¤the same timer footprint with different switch âassignments or rotation directions.
- primary functions: sequencing circuits, providing âŁtimed⣠run/stop âintervalsand indexing manual⢠control knobs.
- Common symptoms of failure: timer⢠fails to â¤advance, intermittent â˘contacts, stuck on a single cycleor âaudible motor hum with no movement.
- Diagnostic steps: check⤠motor supply, measure continuity across individual switches asâ the shaft is moved, â˘and compare harness pinout⣠to the schematic âbefore replacing.
| item | Description |
|---|---|
| Actuation method | Synchronous or step motor driving cam-operated microswitches |
| Connections | Model-specificâ multi-pin harness âor spade terminals; verify wiring diagram |
| Common failure modes | Wornâ gears, failed motor,â pitted⤠switch contacts, broken indexing⢠tabs |
When replacing or troubleshooting the âtimer, match the part number â¤and confirm terminal assignments rather⤠thanâ relying solely on visual similarity; identical-looking timers can â¤differ in which switch closes at each index. For âin-field diagnostics,isolate power,then manually advance theâ shaft while â¤probing switches to confirm expected continuity at each position; if⤠the motor receives correct voltage but does not rotate,the internal drive or gear train is likely atâ fault. During installation transfer any positionâ markers, ensure the shaft and dial align with â¤the appliance’s âcontrol referenceandâ secure mounting to prevent drift that⤠would⢠misalign timed events.
How theâ 131758600 Frigidaire Control Timer Works Inside the Appliance
131758600 Frigidaire Control Timer is âan electromechanicalâ sequencing device that regulates the order and duration âof âmajor âappliance functions by â¤mechanically actuating multiple contact sets as a⢠driven cam assembly rotates.A⣠small⣠synchronousâ or shaded-pole motor inside the⢠module⢠advances the cams,⣠andâ each cam â˘closesâ or opens specific contacts that route âmains power to âthe drive motor, heaters, valves, pumpsor indicator circuits. The timer’s behavior is defined by the â˘cam profiles and âŁcontact arrangement;⤠replacing the timer ârequires matching⣠the part number, wiring harness âpinoutand mounting⣠pattern to ensure the same sequence andâ electrical âconnections are preserved.
In operation the âtimer supplies switched mains to subsystems⤠based on theâ selected program â˘position; wear âor contamination â¤of the cams and contact surfaces âproduces intermittent operation, failure to advance between stepsor loss ofâ one or more functions. Techniciansâ can verify timer faults by â¤observing â˘cam rotation, measuring voltageâ to⣠the âtimer âmotor,⤠and checking continuity âacross the contact terminals in several dial⣠positions. For practical replacement and troubleshooting, compare connector âpin labels andâ use a wiring diagram:â if⣠a cycle never advances or a heater/pump âfails to energize while the motor continues to run, âthe timer’s contacts or drive⣠motor are âcommon culprits and the module should be âtested orâ swapped with an âidentical assembly.
- verify⣠motor drive voltage âand physicalâ cam rotationâ before replacing the unit.
- Measure contact continuityâ across terminal sets âat multiple dial positions to locate intermittent orâ open circuits.
- Confirm connector pinout and mounting alignment toâ ensure compatibility with âŁthe appliance harness.

|---|---|
| Drive mechanism | Motor-driven cam assemblyâ thatâ sequences contact âsets |
| Control outputs | Cam-operated âswitch contacts âthat routeâ mains power to subsystems |
| Interface | Multi-pin electrical connector and mechanical âŁmounting studs/tabs |

Common â¤Failure âŁSymptoms,Electrical â˘Signs,and Diagnostic Readings
The 131758600 Frigidaire⤠Control Timer is an âelectromechanicalâ sequencing device that times and routes line voltage to loads â˘through cam-operated switch contactsâ and a small synchronous or shaded-pole motor. When the⤠timer⤠fails â˘electrically âŁor mechanically,â the most common âŁbehaviors⤠are failure to advance through positions, loss of switched outputs, intermittentâ contact closureor audible motor hum without rotation. Compatibility is resolute by the timer’s terminal layout, shaft âŁorientation,⢠and voltage rating-replacements must match âthe OEM part number and wiring diagram so that each cam-operated contact⣠closes the correct âŁcircuit at the correctâ point â˘in theâ cycle.
- No cycle advancement while the rest of the⢠appliance has power â(motor hums âor âis silent).
- Intermittent or no voltage on one or more switched output terminals while in⢠a position that should be closed.
- Visible arcing, pitted contacts, burnt smellor melted⣠housing near â¤terminals.
- Erratic sequencing causing heaters, compressorsor motors to run âoutâ of order.
| Item | Description |
|---|---|
| Line input | Expect⤠nominal â¤supply on the timer’s line terminal â˘(typicallyâ nominal line voltage for the âappliance). Absence indicates âŁupstream supply or fuse issue. |
| Switched outputs | Should show âŁline voltage when the timer is in positions âthat require âŁthe load; no voltageâ with a confirmed correct position suggests⣠contact failure. |
| Motorâ drive | Motor should draw characteristic operating current and rotate. Line present âŁbut no rotation suggests seized motor or mechanical obstruction. |
| Contact continuity | Closed contacts show⤠continuity âonly âin âthe expected cam positions; âintermittent continuity under wiggle indicates worn âŁor âpitted contacts. |
For practical â˘diagnostics useâ a multimeter to compare the â¤timer’s live input⢠and output voltages⤠against the expected states listed in â˘the appliance wiring diagram,â and perform continuity checks with power removed. If the timer receivesâ proper input âbut fails to⤠provide the expected âswitched outputs, focus on contact wear, âŁcam misalignment,⢠or âan internal motor âŁfault; if outputs are present but âtheâ downstream⤠device does not operate,â test the load independently.When replacing âa â˘failed unit, verify the⤠replacement âmatches the original 131758600 mounting and terminal arrangement âso that timing positions correspond exactly to the appliance’s⢠control scheme.
Replacement Considerations, Compatible Modelsand Step-by-Step Installation
The 131758600 Frigidaire Controlâ Timer is an electromechanical timingâ assembly that sequences refrigeration functions (compressor⣠run, evaporator fanand defrost heater/damper where applicable)⢠by switching AC outputs through a â˘cam-and-contact arrangement driven by a small synchronous motor. Technically, the unit provides discrete⣠timed outputs rather â¤than continuous modulation, soâ failure modes are typically contact wear, a â˘seized âŁdrive⢠motoror broken cam followers; symptoms include lack of cycle advancement, continuous â˘compressor operationor missed/extended defrost âcycles. Confirming compatibilityâ requires checking âŁthe physical mounting, terminal layout, motor voltageand connector type against the service literature or â¤the original timer-do not rely âsolely âon model series names because multiple timers with different terminal configurations have been⣠used across âadjacent Frigidaire model years.
- Check terminal labels and harness⣠pinout before disconnecting the âold timer.
- Verify motor supply voltage (commonly 120 VAC on North American â¤models) and contact⢠ratings against the replacement.
- Compare mounting tabs and shaft âŁorientation to ensure the new timer will engage the cabinet â¤bezel and âdoor interfaces correctly.
- Document and label wiresâ during removal to preserve correct reassembly; photograph the old timer orientation⤠as a reference.
Installation requires basic electrical âsafety and aâ systematic âapproach: disconnect mains power, remove â¤the controlâ bezel or rear access panel âdepending on model,â relieve strain on the harness,⢠and âremove retaining clips or screws holding the timer. When fitting the replacement, align the⢠shaft and mounting pegs, reconnect the harness â¤using the documented pinout, thenâ restore â˘power and observe at⤠leastâ one complete cycle or manually âadvance the timer (where a built-in advance⢠knob isâ provided) to confirm âproperâ sequencing âŁof compressor, fanand defrost outputs. If the replacement does not restore correct âoperation, verify the associated door â˘switches, temperature controland start relay/overload components before assumingâ a timer defect; some symptoms attributed to⢠timers areâ caused by downstream failures.
