131758600â Frigidaire Control Timer is a control-timer module designed to orchestrate timed operations in compatible Frigidaire household appliances. As a purpose-built control component, it provides the timing signals and switching functions that determine the duration and sequence of cycles; implementations may be electromechanical (cam-and-switch) or solid-state (printed circuit board with timebase circuitry and power outputs) depending on the specific model and vintage âŁof the appliance.
Insideâ an appliance the control timer acts as the sequencing heart of âthe system, interfacing â˘with theâ incoming mains power, user interface, sensors â(temperature, water level, door/door lock â˘switches), actuators (motors, pumps, valves, heating elements) and sometimes⣠a main control board. Technically, it translates user â˘selections into timed control outputs and status feedback: it supplies switched power to loads, monitors input statesand coordinates transitions between â¤cycle steps. Typical interactions include driving relay or triac outputs, receiving low-voltage sensorâ signalsand connecting â¤to the appliance harness via keyed â˘terminals; correct timing and reliable switching are thus essential âfor safe, predictable appliance âoperation.
This article will describe how the 131758600 Frigidaire Control Timer functions, how to determine compatibility with specific appliance models, common failure symptoms to recognize (such as failure to advance cycles, stuck or intermittent outputs, burned contacts or erratic timing),⣠and step-by-step⤠troubleshooting approaches technicians can use â(visual inspection, continuity and voltage checks at terminals, outputâ testingand harness verification).â It will also cover practical replacement considerations such as part-number⢠cross-references, connector⣠and mounting compatibility, handling and ESD precautionsand calibration or initialization steps where âapplicable; always disconnect power before servicing and consult the appliance wiring diagram and âmanufacturer documentation for model-specific procedures.

Function and Role of the Control Timer in Frigidaire Appliance operation
The primary âfunction of theâ 131758600⣠Frigidaire control â¤Timer â is to sequence and switch power to refrigeration âsubsystems according âto â¤predetermined intervals and âsafety inputs. In many Frigidaire refrigerators this module energizes the compressor, âdefrostâ heater, evaporator fanand associated relays in âa timed pattern to manage cooling cycles and âperiodic defrosts.The timer accepts inputs from the temperature thermostat â˘and defrost thermostat or sensorand it provides⣠stepped outputs⢠or solid-state switching to the load circuits; a failed timer can leave the compressor running constantly, prevent defrostor stop the compressor entirely depending on which internal contact or electronic driver has failed. Physical âcompatibility (mounting location, harness⤠connectorand terminal mapping) andâ electrical ratings must match the appliance wiring harness to ensure correct sequencing and safe operation.
- Primary behaviors: timed compressor on/off sequencing, defrost â˘cycle initiationand fan control.
- Common symptoms of failure: continuous run, no-run, erratic defrost cyclesor incompleteâ cycle transitions.
- Diagnostic actions: check for proper line voltage at timer⢠input, verify continuity of switch⤠contacts, â¤and manually advanceâ or cycle â¤the timer to observe outputs.
For practical repair and replacement, technicians should compare terminal labels âand the harness connector before installing a âreplacement timer; the âpart number should match or â¤be â˘listed as a compatible optionâ and the mounting and harnessâ must align to prevent miswiring.Troubleshooting frequently enough uses a multimeter to confirmâ supply voltage and contact closure at the timer outputs⤠during expected cycle transitionsand a simple âŁoperational test⤠is to manuallyâ advance the timer (or use a âdiagnostic mode if⣠available) to trigger the defrost circuit and verify load activation. If diagnosticsâ show correct voltage to the â¤timer but⣠noâ switching at outputs, replacing â¤the control timer is typically warranted; document terminal-to-function mapping during removal to avoid wiring errors on installation.

how the 131758600⣠Frigidaire Control Timer Operates Within the Appliance âControl Circuit
The 131758600 Frigidaire Control Timer is a cam-driven sequencing â˘device that directs line voltage to differentâ subsystems âof the appliance according to discrete cycle positions.â A small synchronous motor turns an indexed cam stack or multi-gang switch assembly; each cam lobe or contact pack closes specificâ circuits for defined intervals to energize âheaters, motors, solenoidsor â˘fansâ in the correct order. In practice this means the timer provides both the timing signal and the â˘switchedâ power paths that implement wash/spin/heat/defrost sequences; correct replacement requires matching the original unit’s mounting, terminal layout, contact ratingsand shaft orientation so that the sequence and safety interlocks operate as designed.
- Common symptoms of timer-related faults: no cycle advancement, stuck or skipped stepsand intermittent switching of heaters or motors.
| item | Description |
|---|---|
| Motor type | Line-driven synchronous⤠motor that advances the cam stack (commonly 120 VAC in âNorth American models) |
| Contact sets | Multiple isolated âcontacts (SPDT/DPDT style) that route power to loads based on cam positions |
Technically,diagnosing the timerâ requires verifying that the motor receives its supply voltage during run conditions,and that â˘each contact pair⢠exhibits the expected continuity at âŁthe corresponding indexed positions. A practical test sequence for a technician is: remove power, manually index the timer while measuring resistance across contact terminals to confirm switching, then restore power to confirm motor drive and sequence timing. â¤When replacing the part, âconfirm terminal numberingâ and contact amperage; some later Frigidaire appliancesâ use electronic control modules instead of a mechanical timer, so cross-reference the⤠service â˘manual toâ avoid incompatible substitutions.
Common Failure Symptoms and Electrical/Mechanicalâ Indicators of Timer Fault
The 131758600 Frigidaire Control timer is âan electromechanical sequencing device⣠that times and routes line voltage to motors, solenoid valves, heating elements and interlocks according toâ the user-selected cycle.Internally it uses a small synchronous motor or stepper drive and a stack of cam-operated switch contacts; the cam profile and terminal layout determine how and when powerâ is distributed. Compatible replacements must match the terminal numbering, cam arrangement and mounting â¤features of the original;⢠swapping a visually similar timer with a different cam profile â¤or terminal mapping canâ leave motors or heaters energized at the wrong time or prevent cycle advancement altogether.
Common failure modes produce predictable electrical and mechanical indicators that are straightforward to verify with a multimeter and visual inspection. Technicians will often observe open orâ intermittent continuity on switch contacts, burned or pitted contact surfaces, a stalled âŁadvance motor (no rotation when â¤input âvoltage is present)orâ continuity that fluctuates as the⢠timer is gently rotated âby hand. Practical diagnostic steps include verifying incoming line voltage at the timer supply terminals, checking for the expected output voltage on the switchedâ terminals duringâ a â˘commanded âstepand inspecting the cam stack and gears for worn teeth or⣠melted plastic. For example, a washer that remains in the wash phase while theâ motor and pump receive⤠no switched power often points to failed switch contacts or a stalled drive motor inside the timer; â¤a timer that hums but doesâ not advance typically indicates motor â¤failure or a stripped gear.
- Does not advance through cycles; selector knob â¤or motor does not rotate
- One orâ more functions (pump, motor, â˘heater) receive noâ power despite â¤correct input voltage
- Intermittentâ operation-functions work onyl at certain⤠knob positions orâ after tapping the timer
- Burning smell, arcingor visible carbonization on contact surfaces
- Erratic orâ skipped steps where the timer jumps positions
| Item | Description |
|---|---|
| Continuity test | Measure âacross switch contacts while advancing the timer; look for open circuits or high resistance where closed contacts expected |
| Line vs.switched voltage | Confirm presence â¤of supply voltage at input and expected switched âŁvoltage at outputs when the timer is in the corresponding position |
| Visual/mechanical | Inspect cams, gears and contacts for wear, pitting, melted plasticor âloose terminal â˘connections |
Replacement Considerations, Model Compatibility and Installation procedures for the Control Timer
The 131758600 Frigidaire Control Timer is the timing and sequencing interface that routes power to motors, heaters, valves and switches to enforce the appliance’s programmed cycles. Technically, the component can be anâ electromechanical⣠cam-and-switch assembly⤠or anâ electronic PCB that⣠provides timed relay outputs;â both implementations perform the same role of opening and closing specific circuits⢠in sequence. When evaluating replacement compatibility, compare the stamped part number, connector pinout, shaft diameterâ and direction of rotation, â¤mounting hole patternand the control’s nominal supply voltage and expected load currents. Different production revisions sometimes reuse⢠the same outerâ housing while⣠changing internal switch â¤assignments or PCB revisions, so a physical fit does not⣠guarantee identical electrical behavior-verify functional diagrams or continuity between terminal groups before installation.
Follow a methodical replacement procedure to avoid mis-wiring and to confirm correct operation after fitment. Start by Disconnect power at the breaker, photograph the control and wiringand⣠mark knobâ position and cam orientation; then remove the control assembly, transfer any mechanical cams or âselector⤠components if required,â and confirm that harness connectors mate with the â¤new unit without â¤forcing pins. Use a multimeter to check continuity of common and switched terminals against the âservice schematic, re-secure mounting hardware âŁto avoid chassis â˘strainand run a controlled diagnostic or short cycle âto observe indexing and the sequence of outputs. Practical checksâ that⣠help avoidâ common failures are listed âbelow.
- Disconnect power and document original wiring and⢠knob/cam positions.
- Match connector pinout and verify supply voltage and expectedâ load currents.
- Transfer mechanical parts (cams, shafts) when housings âdiffer but electrical layout matches.
- Measure continuity of expected switched terminals before powering the appliance.
- Perform a functional test cycle and monitor for correct timing â¤and switch closure.
| Item | Description |
|---|---|
| Voltage rating | Confirm âŁcontrol matches the appliance âsupply â˘(e.g., 120 V single-phase) and relay contact ratings. |
| Connector type | Note numberâ of pins, keyed orientation, â˘and wire colors to ensure proper mating. |
| Shaft/orientation | Shaft diameter, length and rotation direction must match knobs and cam alignment. |
| Mounting | Compare hole⣠pattern and bracket locations to prevent âstress on the âcontrol housing. |
Q&A
Whatâ is the 131758600 Frigidaire control timer and what does it do?
The 131758600 â˘is an OEM control timer âassembly used on certain Frigidaire appliances (commonly older electric ranges and wall ovens). âŁIt⤠provides timed switching and clock functions for cook cycles -â turning oven elements or burner circuits on and off according to âthe timer or the cook control settings. It is âan electromechanical control (or an integrated timer/clock) rather than a user-programmable electronic âcontrol board.
How do I know if the timerâ is failing?
Common symptoms of a failing timer include: â˘the timer/clock will not advance or keeps âincorrect time; oven or bake/ broil elementsâ do not turn on when â¤the timer is set; heatingâ cycles stop mid-cycle; âŁintermittent or no power to heating circuits tied to âthe timer; or unusual noises from the timer when operating. Before assuming the timer, verify power to the appliance, fuses/thermal âcutouts, selector switches and⤠wiring, as those failures can produce identical symptoms.
How can I test the 131758600 timer with a multimeter?
Testing requires the appliance be disconnected from power. â¤Remove the control panel to access the timer terminals, label âor photograph wire locations, then set a âmultimeter to continuity or resistance. Consult the appliance wiring diagram to identify whichâ timer terminals control the circuit you are testing; rotate the timer shaft through positions and observe the meterâ – continuity should changeâ according to the wiring diagram (open/closed contacts as the timer advances). Intermittent contact, no âcontinuity where it should be closedor wildly varying resistance indicates a bad timer.If you are not comfortable with live electrical diagnosis, stop and call a technician.
Can I replace the⣠timer⣠myself âand what are the main steps?
Yes, a competent DIYer can frequently enough replace it. Main âsteps: 1) Disconnect power at⣠the breaker (or unplug).⢠2) Remove knobs and access screws for the control panel. 3) pull the⣠panel forwardâ and take photos of wire locations; label connector⤠wires. 4) Disconnectâ wiring harnesses and mounting screws, remove the old timer. 5) Install the new timer in the correct orientation, reconnect harnesses to the exact âterminals, secure the âŁunit and reassemble the panel. 6) restore power andâ test. Always⢠follow the appliance⤠service manual and observe lockout/tagout and electrical âsafety precautions.
Is 131758600 compatible with my Frigidaire model? How do I confirm fitment?
Compatibility depends on the specific appliance model and production date. Do not rely only on a part number⣠match shown in a search. â¤To confirm fitment: locate your appliance modelâ and serial number (usually inside the oven frame or on the appliance⣠chassis), âŁthen check Frigidaire’s parts list or an authorized parts supplier for the exact part number cross-reference. If possible, compare mounting holes and terminal â˘layout with the replacement part. When in doubt, provide your appliance model number to the parts supplier â¤or Frigidaire â˘support.
Are there aftermarket alternatives or cross-reference numbers⢠I âcan use?
Aftermarket replacements or cross-referenced part numbers may exist, but quality and terminal mapping can vary. It’sâ safest to purchase the âŁOEM âŁFrigidaire 131758600 (or the exact part number listed for your model). If considering aftermarket parts, verify terminal identification, mounting compatibility and return policy.Avoid parts that require rewiring unless you⤠are certain of the pinout and electrical âratings.
how much does a replacement timer cost and should â˘Iâ hire a technician?
Prices âvary by supplier and region. OEM timers commonly range⤠from a modest consumer-parts â¤price to higher â¤depending on availability and whether it’s new or rebuilt. Labor to replace a control⤠timer typically takes under an hour âfor a technician,but rates vary. âHire a technician if you are uncomfortable working with mains electrical circuits, if the control is integrated with other electronics, âor âif the â˘problem might involve other components (thermal cutouts, wiring harnessesor control boards) that⣠need professional diagnosis.
Could something else cause the âsame symptoms and notâ theâ timer?
Yes. Identical symptoms can be caused by blown thermal fuses or âtemperature limit switches, faulty selector/surface switches, damaged wiring or connectors, a failed⣠control board that feeds âthe timeror failed heating âŁelements. Always check power supply, fuses/limit thermostats and wiring continuity first. â¤replace the â¤timer only after confirming its contacts or timing mechanism are the source âof the failureor after substitution with a known-good timer.
