131758600 Frigidaire Control Timer is a cycle-timing control module used to sequence operations in household appliances. It is typically an electromechanical or electro-mechanical assembly-commonly described as a cycle timer or control timer-that advances through a programmed set of positions to switch power to various subsystems. The unit is a physical timing device that may incorporate a small synchronous motor, cams or switches, and a multi-pin connector or wiring harness that interfaces with the appliance wiring harness.
Inside the appliance, the control timer’s role is to route mains and control signals to motors, heaters, pumps, solenoid valves, and interlocks in the correct order and for defined durations. It functions as the central timing sequencer for cyclical operations, coordinating when drive motors run, when water or air is admitted, and when heating elements are energized. The timer thus interacts with door or lid switches, temperature sensors or thermostats, motor circuits, and other safety interlocks; as it commonly switches line-voltage circuits and provides timed control, its mechanical and electrical integrity directly affects multiple subsystems.
In this article you will find a technical clarification of how the 131758600 Frigidaire Control Timer operates, guidance on determining compatibility and physical fit, common failure symptoms to recognize, diagnostic checks a technician can perform (visual inspection, continuity and power checks, observation of timed outputs), and practical considerations for replacement. The discussion emphasizes diagnostic logic and mechanical/electrical checks rather than cosmetic or brand claims, and it highlights what to confirm before ordering a replacement-matching part numbers, connector pinout, shaft orientation and mounting-to ensure a proper, safe repair.

Function and Role of the Control Timer in Appliance Cycle Management
The 131758600 Frigidaire Control Timer coordinates the sequence and duration of electrical circuits that run an appliance cycle. As an electromechanical switching assembly (or an integrated control in some designs), it interprets the user-selected program and routes line voltage to motors, valves, heaters, solenoids and pumps in the correct order and for the correct intervals. The timer advances either by a synchronous motor or electronic countdown, and the internal contacts or relays change state at predetermined positions to implement fill, agitate, drain, spin, heat or cooldown phases. Technicians rely on the timer to act as the central cycle scheduler: a failed cam, worn contact, or broken drive will typically stop cycle advancement or cause erratic operation even when individual components test good.
Understanding compatibility and practical behavior helps in diagnostics and replacement: the correct 131758600 Frigidaire Control Timer must match the appliance model, terminal numbering, mounting points, and supply voltage to avoid miswiring or functional mismatch. Common troubleshooting steps include verifying mains presence at the timer input, checking for continuity between timer output terminals during expected steps, observing mechanical cam movement (if visible), and comparing terminal functions to the wiring diagram. Such as, if a washer does not advance from wash to rinse, measure voltage at the timer’s advance/drive terminal while the cycle should change; absence of voltage indicates a timer drive or contact fault rather than a pump or valve failure.
- Primary responsibilities: sequencer for power distribution,timed dwell for each phase,and mechanical/electrical state switching.
- Common symptoms of timer issues: failure to advance, intermittent cycles, burnt or pitted contacts, and no power to specific components.
- Compatibility checks: confirm part number, terminal layout, mounting, and supply voltage against the appliance schematic before replacement.

How the 131758600 Frigidaire Control Timer Works Inside the Appliance and interfaces with Electronics
The 131758600 Frigidaire Control Timer is a timed sequencer that coordinates power distribution and state changes inside the appliance by switching specific circuits on and off according to a programmed cycle. Internally it typically contains a timing mechanism (either a small synchronous motor with cams or an electronic timing circuit) that actuates contact sets or outputs timed control signals. Those contacts route mains-level loads to motors and heaters, while other pins provide low-voltage signals for indicators, interlocks, and logic inputs. Physical compatibility is determined by the connector pinout and mounting arrangement, so replacements should match the part number and connector layout to maintain correct signal routing and safety interlocks.
In operation the timer interfaces directly with sensors, door switches, thermal fuses, and the drive system: its connector pins carry switched mains, return paths, and status signals that other control modules or user switches monitor. For practical troubleshooting,observe whether the timer advances when a cycle is selected,measure voltage or continuity at the output pins as the timer steps through positions,and verify that interlock circuits allow the timer to energize loads. Common behaviors that indicate timer issues include failure to index between steps, contacts that do not close under load, or intermittent switching; test continuity across contact sets and confirm the timer motor or stepping mechanism is receiving its drive voltage before replacing the assembly.
- Controls: drive motors, heaters, valves, indicators, and interlock circuits
- Timing method: motor-driven cams or solid-state timing circuits depending on model
- Interface: multi-pin connector carrying mains switches and low-voltage signals
- Diagnostics: observe indexing, measure outputs during cycle changes, check contact continuity

Common Failure Symptoms and Diagnostic Indicators
The 131758600 Frigidaire Control Timer governs sequence timing for heating, motor run, and door/lock interlocks in compatible Frigidaire laundry appliances. It can be an electromechanical cam-and-switch assembly or a hybrid electronic module depending on production changeovers; either design routes mains and control signals through a set of timed contacts or relays to energize components in the correct order. Failures typically manifest as stuck cycles, no cycle advance, intermittent operation, or failure to energize a specific load even though other loads receive power. When replacing the timer, confirm mating connector style, mounting orientation, and any version-specific wiring diagrams so new part contacts align with the appliance harness and service schematics rather than relying on visual similarity alone.
- Cycle will not advance or remains stuck on a single mode.
- Intermittent starting or runs only when the timer is manually advanced.
- Specific functions (heater, motor, or lock) do not receive power while others do.
- Burnt contacts, arcing noise, or overheating smell near the timer assembly.
- Electrical continuity present across motor or heater, but no supply voltage arrives during the commanded interval.
| Item | Description |
|---|---|
| Continuity across timer contacts | Measure resistance between switched terminals while manually advancing the timer; low ohms indicate closed contact, high/OL indicates an open/faulted contact. |
| Verification point voltage | Observe presence of line voltage at the timer output terminal during the expected part of the cycle (use a live-voltage check with proper precautions). |
Diagnostically, begin with a visual and mechanical inspection: check for melted plastic, loose terminal crimps, and smooth rotation of the timer shaft when actuated by hand. Use a multimeter to confirm that the timer motor or control input receives supply voltage when a cycle is started; if the motor receives voltage but the switched outputs remain open, the internal switch stack is likely failed. Conversely, if no input voltage reaches the timer during start, investigate upstream fuses, door switches, thermal cutouts, and wiring harness continuity. Record observed voltages and contact states against the appliance wiring diagram to isolate whether the fault is the timer itself, an upstream safety device, or a harness/connector fault before ordering replacement parts.
Replacement considerations, Compatibility with Frigidaire Models, and Installation Procedures
the 131758600 Frigidaire Control Timer functions as the sequencing element that directs electrical power to motors, heaters, valves, and switches according to a programmed cycle.In many frigidaire appliances this part uses a small synchronous motor driving a gear train and cam stack to close and open timed contacts; other variants replace the mechanical cams with a PCB and solid-state switching. When selecting a replacement, match the connector layout, terminal count, cam profile or logic outputs, and mounting footprint-differences in any of these can prevent the timer from mechanically advancing, switching the heater, or interfacing correctly with door or safety interlocks. Technicians commonly diagnose timer faults by checking for motor rotation, verifying continuity across timed contacts, and confirming that expected control voltages appear at terminal points during a cycle before ordering a replacement.
- Compatibility checks: terminal type and count, mounting tab positions, cam orientation or PCB pinout, and OEM cross-reference numbers.
- symptoms indicating timer failure: cycles that won’t advance, heater not energizing while motor runs, or intermittent contact continuity.
- Practical installation steps: de-energize appliance, document wiring, transfer any cam assemblies or brackets, verify continuity and motor operation prior to reassembly.
| Item | Description |
|---|---|
| typical terminals | 4-8 flat spade connectors or multi-pin harness; verify pin mapping against schematic |
| Functional tests | Timer motor spins at mains frequency; timed contacts show open/closed states with dial advancement |
Installation should proceed methodically: disconnect mains power, photograph and label each connector, remove the control housing, and compare the replacement timer’s terminal diagram to the old unit before transferring any mechanical cams or mounting hardware. After mechanical installation, perform electrical verification-measure applied control voltage to the timer motor and check continuity between the timer’s switched terminals at the points where the cycle should apply power (such as, heater supply or motor feed). If a suspected compatibility mismatch exists, obtain manufacturer cross-reference data or visually compare the harness and cam geometry; avoiding forced fits prevents mis-sequencing and potential damage to heating elements or motors.
Q&A
What is the 131758600 Frigidaire control timer and what does it do?
The 131758600 is an electromechanical control timer used on certain Frigidaire appliances to advance cycle steps and switch different circuits (motor, heater, valves, pumps, etc.) on and off during a selected program. It contains a small synchronous motor and a set of cams/contacts that close and open at the proper times to control the appliance’s functions.
How can I tell if the timer is failing or needs replacement?
Common symptoms of a failing timer include cycles that will not advance, the appliance getting stuck in one cycle, no power to loads that should be switched by the timer, intermittent operation, or audible humming from the timer motor. Before replacing the timer, check for blown fuses, tripped breakers, bad door switches, loose wiring, or other components that the timer controls. Verify symptoms are consistent with timer failure (for example: other components work when manually energized but the timer won’t advance).
Can I test the 131758600 timer myself, and how?
Yes.Safety first: unplug the appliance or disconnect power before doing continuity checks. Visually inspect for burned or pitted contacts and damaged wiring. Use a multimeter to check continuity across the timer motor windings (you should read a low resistance rather than an open circuit). with the schematic/wiring diagram, you can also check that individual timer switch contacts change between open and closed as you manually rotate the timer shaft (some timers can be advanced manually). To test the motor under power, an advanced check is to temporarily energize the proper timer motor terminals at the rated voltage to see if the motor runs (only if you are experienced and safe with live testing). If you are unsure, have a qualified technician perform live electrical tests.
How do I find out if the 131758600 is compatible with my appliance model?
Check the appliance model number (usually on a tag inside the door opening, on the back, or under the console) and look it up in Frigidaire’s parts lookup, the owner’s manual, or an authorized parts distributor. Parts numbers can be cross-referenced; do not rely solely on appearance. If in doubt, provide your appliance model number to the parts supplier or dealer to confirm compatibility.
How arduous is it to replace the 131758600 timer, and what are general steps?
Replacement difficulty is moderate and varies by appliance.general steps: disconnect power, access the control console (remove screws/panel), document or photograph wiring connections, disconnect the wiring harness and any mounting hardware, remove the old timer and install the new one in reverse order, reconnect wires exactly as documented, reassemble the console, and restore power. Some models require minor calibration or cycle verification after installation. If you are not cozy working with mains voltage or disassembling the appliance, hire a qualified technician.
Are there common installation pitfalls or safety concerns I should be aware of?
Yes. Always disconnect power (and gas supply for gas appliances) before starting work. Mark or photograph wire connections-mixing wires can damage the appliance. Avoid touching live circuits during live tests. Ensure screws and fasteners are tightened so the timer is secure; loose mounting can cause poor contact. After reassembly, check that the appliance starts and cycles normally and inspect for any signs of electrical arcing or burning. For gas appliances, check for proper burner ignition and gas tightness before regular use.
Can the timer be repaired (contacts cleaned) or should it be replaced?
Minor contact pitting or carbon build-up can sometimes be cleaned and the timer will work properly again. However, if contacts are severely burnt, cams are broken, or the motor is weak, replacement is usually the more reliable and safer option. Repaired timers may fail again; when reliability is important, install a new OEM or high-quality replacement.
Where can I purchase a genuine 131758600 Frigidaire control timer and what should I check before buying?
Genuine parts are available from Frigidaire’s authorized parts distributors, appliance parts stores, and reputable online retailers. Before buying, verify the part number matches the part specified for your appliance model, check the seller return policy and warranty, and prefer OEM parts or well-reviewed aftermarket equivalents. If you’re uncertain about compatibility, provide your appliance model number to the seller and confirm fitment before purchase.
