316455430 Frigidaire Oven Timer Clock is an electronic timer/clock assembly designed for Frigidaire ovens and ranges. It combines timekeeping and user-interface functions with control outputs that manage timed cooking operations; physically it is typically mounted in the console or control panel and includes the display, keypad or touch controls, and the internal circuit module that communicates with the oven’s main control circuitry.
Within the appliance, the timer/clock coordinates timed events (cook time, delay start, end-of-cycle alerts) and acts as an interface between the user and the oven’s power control elements. It exchanges signals with the main control board or relay/triac circuits to enable or disable heating elements, and it can interact with safety interlocks and temperature sensors so that timed operations respect thermostatic limits and door-lock states.the module therefore has both human-interface and control-plane responsibilities: presenting status and accepting commands while producing control signals that affect the heating and safety subsystems.
in this article you will find a technical overview of the 316455430 timer/clock’s function, guidance on checking compatibility with oven models and control harnesses, common failure symptoms (such as blank or frozen displays, unresponsive keypad, inability to initiate timed cycles, or intermittent control outputs), practical troubleshooting steps (power and connector checks, basic voltage and continuity tests, interpreting error behaviour), and considerations for safe replacement (confirming part number and included components, power isolation, mounting and wiring differences, and any necesary post-replacement checks). The goal is to provide technicians, engineers, and appliance owners with the diagnostic context needed to evaluate and, when appropriate, replace this component safely and effectively.

Function and role of the oven Timer Control in Frigidaire Range Control Systems
The 316455430 Frigidaire Oven Timer Clock serves as the range’s timekeeping and user-interface module,providing the digital clock,countdown/timer functions,and the timed control signals used for automatic cook and delay-start sequences. In typical Frigidaire designs this module interprets user inputs and issues low-voltage control commands to the main range control board; the board then implements high-current switching for bake or broil elements. Because the oven timer sequences and interlocks timed events, electrical or mechanical incompatibility (different connector pinout, signal logic, or firmware expectations) between this clock and the main control will prevent timed functions from operating correctly even if basic manual oven functions remain available.
- Digital clock and countdown/timer display
- Timed cook, delay-start and automatic shutoff sequencing
- Low-voltage control outputs to the main range control board
- User input interface (buttons/knob) and status indicators
Technicians diagnose clock-related faults by observing display behavior, confirming that user inputs register, and measuring the module’s control outputs while initiating a timed cycle; absence of expected control signals at the harness pins indicates a defective timer module, whereas correct signals with no oven action point to a main control or power-relay fault. Practical replacement requires matching the specified part number or an approved cross-reference and verifying connector pinout and mounting alignment; after replacement validate countdown accuracy, timed shut-off, and retention of clock settings across brief power interruptions to confirm correct integration with the range control system.

How the 316455430 Frigidaire Oven timer Clock Works Inside the Appliance: Circuitry, Signals and Control Interfaces
The 316455430 Frigidaire Oven Timer Clock is a user-interface and timing module that contains a small microcontroller, display driver circuitry, keypad scan hardware and I/O lines that connect to the range’s main control board. Inside the appliance it keeps track of elapsed and timed cook events, presents time and status on the display, and issues digital enable signals or command pulses to the main controller to start or stop heating cycles, control timed bake functions, and trigger the audible alarm. In practice this means the part translates button presses and scheduled timers into logic-level commands across a multi-pin connector or ribbon cable; such as, a programmed delayed-start causes the module to assert a control output at the scheduled time so the main board energizes the bake element.
- Power – low-voltage supply for logic and display
- Ground – common reference for signals
- Display/data lines – segment drivers or serial display bus
- Keypad matrix – scanned input lines for buttons
- Control outputs - enable/command lines to main control (relay/triac drivers)
Signal-level behavior is digital rather than high-voltage: the clock typically operates on a low-voltage logic rail (commonly in the 3-5 V range) and communicates to the power controller with discrete parallel lines or a simple serial protocol,depending on the model. Technicians diagnosing failures check for the presence of the logic supply and ground at the module connector, observe keypad scan activity and display drive signals with a scope or logic probe, and verify that the control output lines change state when timer actions are invoked; a blank display combined with an oven that still heats usually indicates a clock-module fault or connector issue, while a working display with no heating suggests the main control or its power stage has failed. Compatibility is determined by the connector pinout and firmware behavior-replacements must match the original pin assignments and signaling conventions to function correctly.
| Item | Description |
|---|---|
| Power | Low-voltage supply for microcontroller and display (typical logic rail) |
| Data/Clock | Serial or parallel lines that carry button inputs and display commands |
| Control Output | Logic-level enable or command to the main control to activate heating/relays |
Common Failure Symptoms and Diagnostic Indicators for the Oven Timer Clock
The 316455430 frigidaire Oven Timer Clock is the user-interface and timing controller that coordinates oven cycles,display readout,and the control board interlocks.It receives household line power and low-voltage logic from the oven’s control harness, interprets user input from the keypad, and drives the display and internal timing relay outputs that tell the range to start or stop heating. Technicians should confirm board compatibility and connector pinout before replacing this module; verify model fitment and connector pinout to avoid mismatches in signal routing or voltage levels that can produce similar failure symptoms across different frigidaire ranges.
Common failure symptoms are grouped by user-visible behavior and measurable diagnostic indicators, which guide whether the issue is with the clock assembly, wiring, or the main control. Typical indicators include a blank or partially lit display, loss of timekeeping when power is uninterrupted, oven functions not starting when the timer is used, or erratic resets as the oven heats. Practical diagnostics start with visual inspection for burnt components or cold solder joints, followed by harness checks for continuity and voltage: confirm ~120 VAC line presence at the range’s terminal block when the appliance is powered and verify any DC logic voltages on the clock board (as specified by the service manual). Intermittent faults often track to thermal stress on solder joints or connector corrosion rather than the display itself.
- Blank display or missing segments - may indicate failed display driver or lack of DC supply.
- Clock resets when oven heats - possible heat-related solder cracks or failing components.
- Timer does not start oven functions – likely faulty relay output or broken signal on the connector.
- Touchpad inputs ignored or intermittent – keypad membrane or connector contact fault.
| Item | Description |
|---|---|
| Blank display | Check DC supply rail and connector pins; replace clock if supply present but display driver is dead. |
| Resets with temperature | Inspect solder joints and component heating; rehearse fault with thermal probe to locate failing parts. |
| No oven start when timer set | Verify relay/control output continuity and 120 VAC at the control board during a start attempt. |
compatibility, Replacement Considerations, and Installation Procedures for Affected Frigidaire Models
the 316455430 Frigidaire Oven Timer Clock is the user-interface and timing module that manages the oven clock, countdown timer, timed-bake and delayed-start functions while providing the front‑panel display and keypad inputs. Internally it couples low‑voltage digital control circuitry to the oven’s switching elements (relays or triacs) thru a multi‑pin harness and may exchange status with the main oven control board; therefore physical fit, connector pinout, and signal assignment must be verified before replacement. In practice, two visually similar modules can have different connector layouts or software revisions, so technicians should confirm the OEM part number and inspect the PCB connector and bezel alignment against the appliance before installation to avoid mismatched signals or mechanical interference.
Replacement and installation require basic electrical safety and methodical verification: disconnect power, remove the trim or control bezel, photograph and document wiring and connector orientation, then release the clock module from its mounting points. Handle the display glass and ribbon cables carefully to avoid flex or static damage, seat the harness fully and secure any retaining clips, restore power, then verify clock setting, timed-bake operation and that relays/indicators respond correctly; a short self-test cycle or initiating a timed bake is a practical functional check. If symptoms persist after replacement – erratic display,no timer function,or control lockouts – investigate the main control board,harness continuity,and ground references before assuming a second clock module failure.
- Confirm OEM part number and connector pin count
- compare bezel/mounting dimensions and screw locations
- Verify harness pinout and signal assignments with continuity checks
- Test functionality after installation (clock, timer, timed-bake)

Q&A
What is the Frigidaire part 316455430 and what functions does it perform?
Part 316455430 is the OEM electronic clock/timer/oven control assembly used on certain Frigidaire ranges and wall ovens. It provides the front-panel clock and timer display, user input buttons or touchpads, and the control logic that manages timed cook functions, oven bake/broil cycles (on models where the control handles those functions), and some safety interlocks. In short, it’s the user interface and control module for timekeeping and timed cooking operations.
How can I tell if the 316455430 clock/timer is failing?
Common symptoms of a failing unit include a blank or flickering display, buttons or touchpad that do not respond, the oven failing to start when a timed function is selected, the clock losing time or resetting, or error codes appearing on the display. Before replacing the module,verify power to the appliance (circuit breaker),check for a blown thermal fuse or oven door interlock (if applicable),and inspect wiring and connectors for damage. If the control receives correct line voltage and other components (elements, relays) test OK, the clock/timer is a likely cause.
How do I safely replace the 316455430 clock/timer assembly?
Always disconnect power to the appliance at the breaker panel before servicing. Typical replacement steps (may vary by model): 1) Remove the top/back control panel trim or console screws to access the control.2) Remove any knobs or trim pieces. 3) Unfasten the control assembly screws and carefully pull the module forward. 4) Note the orientation and connector positions, then unplug the multi-pin wire harness(es). 5) Install the new unit by connecting the harnesses, securing the module, and reassembling panels. Restore power and test functions. If you’re not comfortable working with live electricity or disassembling the console, hire a qualified appliance technician.
Do I need special tools or calibration after installing the new control?
No specialized calibration tools are usually required. Basic hand tools (screwdrivers, nut drivers, and a multimeter for diagnostics) are sufficient. After installation, you typically need to restore power and set the clock and any user preferences (time format, demo mode off). Some models perform a self-test on first power-up; consult the oven’s service manual for model-specific post-install procedures. if the oven has temperature calibration or offset features, those are separate settings and are not commonly required just for replacing the clock/timer unless you notice temperature issues.
How can I check electrical power to the clock/timer before replacing it?
With power connected and using a properly rated multimeter, check for line voltage at the control’s power terminals (most frigidaire controls use 120 VAC). First ensure you know which terminals supply incoming power (refer to wiring diagram or service sheet). Verify the house breaker and any fuses or thermal cutouts are intact. If there is no incoming voltage, repair the supply circuit before replacing the control. If 120 VAC is present at the control but the display is blank or nonresponsive, the control itself is highly likely defective.
Is 316455430 compatible with my Frigidaire model and how do I confirm fit?
Compatibility depends on the oven model and production date. Confirm fit by checking the appliance model number (usually found on a tag behind the oven door, on the frame, or behind kick plate) and cross-referencing it with Frigidaire parts lists or an authorized parts dealer. Do not rely solely on visual similarity – mismatched controls can have different connectors or firmware. Purchase the part by matching your appliance model to the part number to ensure correct fit.
My oven won’t start when I use the timer; could 316455430 be the problem?
Yes, if the oven control/clock governs timed cooking, a faulty unit can prevent the oven from starting when a timed function is selected.Though, other causes include lost power, a tripped breaker, a failed bake element, defective relays, or safety interlocks. Diagnose by confirming power to the control, checking for correct relay operation (listen for clicks when functions are selected), and testing the heating elements for continuity. If the control receives power but does not switch outputs correctly, it is indeed a likely failure.
Where can I buy a genuine replacement 316455430 and is there a warranty?
buy genuine Frigidaire OEM parts from Frigidaire/Whirlpool authorized parts distributors, appliance parts retailers, or the manufacturer’s parts website.Many reputable appliance parts stores will let you confirm compatibility by model number before purchase. OEM parts typically include a limited warranty (frequently enough 90 days to one year) - check the seller’s and manufacturer’s warranty terms before buying. Avoid unverified aftermarket boards unless you confirm compatibility and warranty support.
