The 131758600 Frigidaire Control Timer is a control-timer module designed to manage the sequencing and duration of an appliance’s operational cycles. As a timing/control component, it provides the timed switching and state sequencing that coordinate motors, solenoids, heaters, and other actuators; depending on the specific model it might potentially be implemented as an electromechanical cam timer or as an electronic timed-control board housed in the appliance console.
Inside the appliance the control timer acts as the central timing and sequencing element,accepting user inputs and line power,issuing time-based output signals to drive motors,pumps,valves and heating elements,and interfacing with sensors or interlocks for basic feedback. It typically connects to the wiring harness and control panel, and its outputs are used to energize relays or direct loads; failures or mis-timing at this module thus affect multiple subsystems and can produce symptoms such as stalled cycles, failure to advance, or continuous operation of a single function.
In this article readers will find a technical overview of the control timer’s function, guidance on compatibility and part cross-references, common failure symptoms to recognize, step-by-step troubleshooting strategies (including safety checks, electrical tests and signal verification), and practical replacement considerations such as correct part selection, harness and mounting issues, and brief notes on calibration or initialization where applicable. The aim is to provide technicians, engineers and appliance owners with the context and diagnostic approach needed to assess, test and replace the 131758600 control timer safely and effectively.

Function and Role of the Control Timer: Electrical Interfaces, Control Logic, and System Responsibilities
The 131758600 Frigidaire Control Timer functions as the timing and sequencing hub that governs when motors, heaters, valves, and indicators are energized during an appliance cycle. Its electrical interfaces typically include the mains input, neutral and chassis ground, multiple switched outputs sized for motor/heater inrush and steady-state currents, and low-voltage signal lines for sensor or interlock inputs. internally the unit implements deterministic control logic-either via mechanical cam-operated switches or an electronic PCB with firmware-that advances through predefined states based on elapsed time and the status of safety interlocks such as door switches and temperature sensors.
For compatibility and practical servicing, match a replacement timer to the original’s terminal layout, timing profile, contact ratings, and physical mounting; differences in contact sequencing or output ratings can produce intermittent operation or unsafe conditions. Technicians should verify continuity of switched contacts during manual advancement, confirm that outputs deliver proper supply voltage under load, and inspect for burned contacts or broken drive components when cycles skip or fail to advance. Common responsibilities, observable symptoms, and typical diagnostic checks include:
- Sequencing live loads to motors, heaters, and valves and ensuring interlocks prevent unsafe transitions.
- Driving loads with contacts or driver circuits sized for inrush currents and controlling dwell times for each state.
- accepting feedback from sensors and interrupting/altering timing if safety conditions are detected.
- Symptoms of failure: no advance, skipped steps, persistent run of a heater or motor, audible arcing or clicking at the timer.

How the 131758600 Frigidaire Control Timer Works inside the Appliance
The 131758600 Frigidaire Control Timer is an electromechanical timing assembly that sequences electrical circuits inside compatible Frigidaire appliances by advancing a shaft-driven cam stack. A small synchronous motor turns the cam assembly at a controlled rate; cam lobes operate multiple switch contacts that route line or control voltage to heaters, motors, pumps, and valves in the appropriate order. The timer mounts to the control panel and interfaces with the appliance harness via a multi-pin connector and a mechanical coupling to the cycle selector knob, so physical shaft alignment and connector pinout must match the appliance during replacement.
- Common behaviors: sequential switching of heating and motor circuits,stepped dwell positions for soak or cool-down,and manual cycle selection via the front knob.
- Typical failure symptoms: timer failing to advance, intermittent energizing of components, audible grinding or motor noise, and contact arcing that causes inconsistent heating or motor operation.
Inside the appliance the timer translates rotational motion into timed electrical events: each cam lobe closes or opens specific contacts at prescribed points in the cycle, which permits simple, reliable sequencing without digital control logic. Technicians troubleshooting a suspected timer fault should verify the motor is receiving supply voltage, confirm continuity across cam-controlled contacts in multiple positions with a multimeter, and inspect for burnt contacts or mechanical wear on the shaft and coupling.Replacements should be cross-checked for pin configuration and mounting orientation; for example, a timer that advances but does not actuate the heater usually indicates contact failure rather than a motor issue.

Common Failure Symptoms, Diagnostic Indicators, and Typical Failure Modes
The 131758600 Frigidaire Control Timer is an electromechanical sequencing device that routes line voltage to multiple circuits in a timed order, using a small synchronous motor or gear train to actuate cams and contact sets. in practical service, the timer’s role is to close and open specific terminals at defined points in a cycle so valves, motors, and heaters receive power in the correct sequence. Compatibility depends on terminal identification,rotation direction,mounting orientation,and the number of contact poles; installing a visually similar timer with different terminal mapping can produce incorrect sequencing even if the unit installs physically. Typical observable behavior of a healthy timer is steady, consistent advancement of the cam stack with clean, low-resistance contacts; deviations from that behavior point toward mechanical wear, motor failure, or contact deterioration.
- No cycle advancement or frozen position in the middle of a cycle.
- One or more functions (motor,heater,valve) permanently on or off while other functions operate.
- intermittent operation or erratic timing that changes between cycles.
- Visible burning, pitted contacts, melted terminals, or corrosion at the connector harness.
- Audible grinding,slipping gears,or a stalled/soft-running timer motor.
Diagnostic work should start with verifying supply voltage to the timer and then checking outputs while the unit is commanded through a cycle: measure AC at input and each output terminal, observe cam motion, and use an ohmmeter to verify continuity across contact sets at expected cam positions. Practical checks include measuring motor winding continuity (open winding indicates motor failure), inspecting cam lobes and plastic gears for wear or breakage, and probing for high resistance across contacts which can cause voltage drop under load even when continuity is present. Typical failure modes are seized or worn motor shafts, stripped plastic gears, pitted or welded contact surfaces, moisture-induced corrosion of terminals, and cracked traces on electronic timer variants; each of these produces distinct diagnostic signatures that guide repair versus replacement decisions.
| Item | description |
|---|---|
| Motor winding | Should show continuity; an open winding indicates a failed motor that prevents cam advancement. |
| Contact sets | Check for continuity only when cam position dictates closure; pitting or high resistance suggests replacement. |
| Connector/terminals | Inspect for loose or melted terminals and measure voltage under load for signs of voltage drop. |
Replacement Considerations and Installation Procedure: Part Verification, Tools, and Step-by-Step Fitment
the 131758600 Frigidaire Control Timer is a motor-driven cam switch that sequences electrical circuits for timed functions such as wash cycles, valve actuation, and motor start/stop events. Internally it combines a small synchronous motor with a rotary cam stack and a set of contact banks; as the motor advances the cams, discrete contact closures route line voltage to different loads.Compatibility requires matching the part number,terminal layout,mounting flange orientation,and shaft diameter/length to the original unit as a mechanically identical timer with a different cam profile or terminal assignment will not reproduce the intended sequence and can leave heaters,pumps,or motors energized at the wrong times. Practical verification includes comparing the harness connector numbers and physical mounting points, checking that the replacement provides the same drive direction and detent positions, and confirming the timer motor rating and supply voltage match the appliance wiring to avoid premature wear or incorrect timing behavior.
- Safety and access: Disconnect mains power and remove the control console or back panel to access the timer.
- Tools: nut drivers, insulated needle-nose pliers, digital multimeter, small flat driver for retaining clips, and a camera or labeling tape to record wire positions.
- Part verification: visually compare terminal IDs, measure shaft length and diameter, and test continuity across expected contacts before installation.
- fitment steps: label wires, remove retaining hardware, transfer any knobs or cams, install the new timer in the same orientation, secure fasteners, reconnect wires per labels, then restore power and observe at least one full cycle for correct sequencing.
| Item | Description |
|---|---|
| Function | Motor-driven cam switch that sequences control circuits and timing events |
| Electrical | Line-voltage driven synchronous motor and multiple contact banks (verify voltage on unit) |
| Mechanical | Shaft diameter/length, flange mounting, and cam profile determine fit and sequence |
| Diagnostics | Continuity checks across cams, motor supply voltage during operation, and visual inspection for wear |
After mechanical fitment, verify operation by measuring the timer motor supply voltage while advancing through cycles and observing the contact closures with a multimeter or test lamp; intermittent contacts or a stalled motor indicate either internal wear or mismatched cam profiles.If sequence errors persist, document terminal-to-function mapping from the original timer and compare it to the replacement-rewiring should only be performed when the mapping confirms identical functions. Final checks include ensuring knobs engage detents correctly, fasteners are torqued to prevent movement under vibration, and that the appliance completes a full programmed cycle with expected actuator behavior and no unexpected heating or motor engagement.
Q&A
What is the Frigidaire part 131758600 and what functions does it perform?
Part 131758600 is the OEM control/timer (clock and user interface) assembly used on certain Frigidaire ranges and ovens.It provides the front-panel clock, countdown/elapsed timer, and user controls for timed baking or delayed start functions. In models where it’s used it may also route user commands to the oven’s main control board (start/stop, bake/broil selectors, and timer alerts).
How can I verify that 131758600 is the correct replacement for my appliance?
Do not rely only on the part number you find online.Verify compatibility by checking the appliance’s model number (usually on a tag inside the oven door frame, behind the cooktop, or on the back of the appliance) and comparing it to the parts list for that specific model. You can also cross-check with an authorized Frigidaire parts dealer or the manufacturer’s parts diagram. Physically compare the connector harness and mounting holes to ensure the replacement will plug in and mount the same way.
What are common symptoms that indicate the control/timer (131758600) is failing?
Typical symptoms include: the clock display is blank or intermittent; timer functions won’t start or don’t count down; oven won’t accept timed start/delay commands; front-panel buttons or touchpads are unresponsive; or the timer beeper doesn’t sound. if the oven won’t heat at all, that can be caused by the main control rather than the clock/timer-so check for other signs before assuming the timer is the cause.
How should I troubleshoot before replacing the control/timer?
First, safely disconnect power to the appliance. Check for blown house or appliance fuses and tripped breakers. Inspect the timer display and front-panel connectors for loose wiring or corrosion. If your model has a separate main control board, try resetting the appliance by disconnecting power for 1-5 minutes and then reconnecting. Verify related components: oven temperature problems often stem from a failed temperature sensor/thermistor, bake/broil elements, or the main control, not the clock/timer. If you have a voltmeter, you can verify that the clock assembly is receiving proper line voltage and that connectors show continuity. If only the display or buttons fail while oven functions remain normal, the clock/timer assembly is the likely culprit.
Is it safe and straightforward to replace 131758600 myself?
Replacing the control/timer is a moderate DIY job if you are comfortable working with appliances and can safely disconnect power. Basic steps: disconnect power at the breaker, remove the backguard or control console screws to access the assembly, carefully unplug the wire harness(es), transfer any mounting brackets, and install the new unit in reverse order. Take photos of wire locations before disconnecting to avoid miswiring. If you are not comfortable with electrical work or the unit is hard-wired, hire a qualified technician. Always disconnect power before starting.
Will replacing the timer fix oven temperature or cycling problems?
Not necessarily. The clock/timer handles timekeeping and user interface tasks; temperature control and heating cycles are managed by the main oven control board and the oven temperature sensor (thermistor or RTD). If the oven is overheating, underheating, or not maintaining temperature, first check the temperature sensor resistance and the bake/broil elements, and consider the main control board. Replace the clock/timer only when symptoms point to display/timer/button failure or timed-start problems.
How do I program or use the timer/clock functions on this control?
Programming steps vary by appliance model. Generally you set the clock by pressing a “Clock” or “Set” button and adjusting hours/minutes with +/- or arrow keys. For the kitchen timer, press “Timer,” enter the desired minutes/seconds, and press “Start” or “Timer Start.” For delayed start, choose “Delay Start” or “Start Time,” enter the cook time and desired finish time, then select the cooking mode and temperature. Consult your appliance’s user manual for exact sequences and button labels. If you no longer have the manual, many Frigidaire manuals are available online by searching your appliance model number.
Where should I buy 131758600 and does it come with a warranty?
Buy OEM parts from authorized frigidaire parts dealers, reputable appliance parts retailers, or directly from the manufacturer to ensure authenticity. Aftermarket copies are available but may vary in quality. OEM parts typically include a limited manufacturer warranty (often 90 days to 1 year depending on the seller); check the seller’s warranty and return policy before purchase. Keep your appliance model number and the part number handy when ordering to avoid compatibility issues.
