316455430 Frigidaire Oven Timer Clock is an electronic clock and timer assembly used on Frigidaire electric ranges and wall ovens. It functions as the user-visible timing and control interface-providing the digital clock display, timer countdown, and programmed start/stop functions-and houses the control circuitry that coordinates timed oven operations. As a replaceable control module, the part number identifies the specific assembly and form factor used in compatible appliance consoles.
Inside the appliance, the timer/clock interfaces with the oven control system, the user keypad/display, and the power distribution elements that drive heating circuits and safety interlocks. It communicates timing and user commands to the main control board or directly actuates internal relays depending on the model design, and it monitors inputs such as the oven temperature sensor and door-lock status during cycles like timed baking or self-clean. Proper operation of this module is important because timed control affects cycle sequencing, automatic shutoff, and coordination with safety features; failures can therefore prevent scheduled operation or create unsafe conditions if left unaddressed.
In the article you will find a technical explanation of the 316455430 timer/clock’s function and typical wiring and mounting, guidance on model compatibility and identifying equivalent assemblies, common failure symptoms (for example no display, inaccurate timekeeping, inability to start/stop timed cycles, or intermittent relay operation), and structured troubleshooting steps including power and continuity checks, harness and connector inspection, and basic diagnostic tests. Replacement considerations such as verifying the correct part number, connector pinout, physical fitment, and safe power-disconnection procedures are also covered to help technicians and owners make informed service decisions.

Function and Role of the 316455430 Frigidaire Oven timer Clock in Oven Control Systems
The 316455430 Frigidaire Oven Timer Clock serves as the oven’s timekeeping and user-interface module and plays a direct role in sequencing timed cooking events. It maintains the display and clock, accepts keypad commands for delayed start and minute-timer functions, and issues logic or contact-closure outputs that command the main power relays and audible indicators during programmed cycles. In normal operation the module sequences bake and broil timings in coordination with the oven control board and temperature sensors,and failures of the timer typically present as a blank or garbled display,inability to start timed bake cycles,unexpected alarms,or failure of the oven to exit a timed mode.
- Timekeeping and display of real-time clock and countdowns
- Control signal outputs that trigger bake/broil relays and audible alerts
- User-interface handling for delayed start, minute-timer, and cancellations
- Basic diagnostics and status reporting to the main control board
- Replacement compatibility dependent on connector pinout and firmware expectations
Compatibility and practical troubleshooting depend on matching the connector layout, mounting, and expected signal logic rather than just a visual match; two boards that look similar can behave differently if their pin assignments or firmware differ. For field replacement or bench testing, verify that the timer responds to keypad inputs, retains or restores time if designed with nonvolatile memory, and that its output lines toggle during a simulated timed cycle using a multimeter or test lamp. Examples of practical contexts: swapping the timer frequently enough resolves symptoms like erroneous alarms or non-starting delayed bakes, but persistent issues after replacement point toward the main control board, door interlocks, or sensor faults and should be checked before assuming the timer is at fault.
| Item | Description |
|---|---|
| Connector | Multi-pin harness; must match oven harness pinout for correct signaling |
| Primary functions | Clock/display,timed-event sequencing,user inputs,and status outputs |
Internal Operation and Electrical Interface of the Oven Timer Clock Module
The 316455430 Frigidaire Oven timer Clock contains a small embedded controller that handles the user interface (clock,timer,and keypad scanning),a display driver for the LED/LCD segment(s),a low-voltage power supply derived from the oven line,and switching outputs that interface to the oven’s control circuits. in many Frigidaire ranges this module provides timed control and user commands while signaling or directly switching relays/triacs that enable bake, broil, or timer-controlled functions. Internally you will commonly find a real-time clock oscillator and nonvolatile configuration memory for clock/timer settings, input debouncing for the keypad, and opto- or relay-based isolation where the module switches high-voltage lines; these elements determine both functional behavior and how the part must be connected to the harness when replacing it.
For practical troubleshooting and compatibility assessment, verify that the wiring harness and connector pinout match the original assembly and measure the expected line and control voltages before replacement. Common diagnostic checks include confirming the module receives mains supply on the designated input pins, verifying switching continuity at the output contacts when bake/broil is selected, and observing the display/controller response to keypad commands; a blank display frequently enough indicates power-supply failure or connector/cable issues rather than the display driver itself.When replacing the unit, use the exact part number or confirm connector, mounting, and signal mapping with the oven’s service sheet because different firmware revisions or harness layouts can change compatibility. Basic safety: disconnect mains power before probing or swapping the module and use an insulated meter probe when measuring live circuits.
- Key interface features/diagnostic points: supply input (mains), display driver, keypad matrix, control outputs (relay/triac), and the connector pinout to the main oven wiring harness.
- Common symptoms: blank or flickering display, unresponsive keypad, clock resets after power outages, or oven functions that fail to start when commanded from the front panel.
- Simple bench checks: confirm mains present at the module, check for expected switching on control outputs during commanded cycles, and inspect connector pins for corrosion or damage.

Diagnostic Symptoms and Common Failure Modes of the Oven Timer Clock
The 316455430 Frigidaire Oven Timer Clock is the user-interface and timing module that provides timekeeping, delayed-start/timer functions, and control signals to the oven’s main control circuitry. In normal operation the module displays clock/timer data, accepts keypad input, and actuates internal relays or solid-state outputs that permit the oven’s heating elements to energize at specified times. Compatibility is determined by the OEM part number and connector pinout, so technicians should confirm the 316455430 Frigidaire Oven timer Clock matches the oven’s harness and mounting footprint before replacement; mismatched pin assignment can produce symptoms similar to module failure even when the board is or else functional.
Common diagnostic symptoms include a blank or flickering display, unresponsive touchpads or buttons, intermittent resets during cooking cycles, and failure of the oven to start or to turn off when timed programs expire.Typical failure modes are degraded electrolytic capacitors on the timer’s power supply, cracked solder joints at connector pads, failed display driver ICs, corroded ribbon connectors, or stuck/shorted relay outputs. Practical checks include verifying the incoming supply voltage to the module, inspecting solder joints and connectors for heat damage or corrosion, and confirming relay coil continuity and control logic signals with a multimeter or oscilloscope; replacement is appropriate when component-level repair is impractical or when faulty firmware/ICs prevent reliable operation.
- Blank/flickering display – likely power supply or display driver fault
- Buttons unresponsive – keypad matrix, connector, or controller failure
- Intermittent resets – power filtering capacitors or loose connector
- Oven not heating or always heating - stuck relay or shorted output
| Item | Description |
|---|---|
| Incoming Power | Verify expected AC/DC supply at the module connector before replacing the timer. |
| Connector & Solder Joints | Inspect for corrosion,broken traces,or cold joints that cause intermittent faults. |
| Relay/Output | Check relay continuity and that control pins toggle when commands are issued. |
Replacement Considerations, Installation Steps and Model Compatibility for Frigidaire Oven Timer Modules
The 316455430 Frigidaire oven Timer Clock is the user interface and timing controller that manages the ovenS clock display, countdown timer, and timed-cook functions. Internally it contains the display/logic assembly and the wiring interface to the range’s main control board; in some designs the module also provides a switching output for timed-bake circuits. Typical operational failures are a blank or flickering display, inability to set or start a timed cook, or incorrect clock retention after power interruptions. As the assembly communicates directly with the main control harness, mechanical fit and electrical connector pinout must match the oven’s service documentation to ensure correct behavior across different Frigidaire models.
When replacing the module, verify the oven model number and compare the connector and mounting pattern of the replacement to the original unit; mismatched pinouts can leave the display powered but prevent control signals from reaching the oven control board. Physically inspect the original part for heat or moisture damage and check harness continuity before installing the new module. After installation, apply power and confirm both the clock display and timed functions operate (for example, set a short timed bake and verify the oven turns on/off as expected); if the display powers but functions are missing, re-check pin assignments and consider that the main control board may be at fault rather than the clock module.
- Disconnect power at the breaker before starting.
- Remove control panel bezel and retain fasteners to transfer to the new unit.
- Unplug the multi-pin harness and label wires or take a photo for reference.
- Install new module, reconnect harness, reassemble panel, then restore power.
- Run a functional test: set clock, use countdown timer, and perform a short timed bake.
