316455461 frigidaire Wall Oven Electronic Clock/Timer is an electronic control module that provides timekeeping, user interface and timing functions for compatible Frigidaire built-in wall ovens. As an integrated clock/timer assembly, it typically includes a display, input keys or touchpads, and the logic required to present time, set countdown or delayed-start cooking cycles, and communicate user commands to the oven’s control system.
Inside the appliance the clock/timer serves as both an data display and a control coordinator: it reports the clock to the user,implements timer and minute‑timer functions,and conveys timed events (such as delayed start or automatic shutoff) to the oven’s central control or power switching components. The module usually interfaces with the main oven control board via multi‑pin connectors or ribbon cables, and it shares power and signaling paths with the keypad, display, and relay or SSR circuits that drive heating elements (or with ignitor circuits in gas models). Its correct operation therefore affects scheduling, user input acknowledgment, and the sequencing of heating operations during timed cycles.
In this article readers can expect a clear technical clarification of the 316455461 clock/timer’s function and physical characteristics, guidance on determining compatibility with specific Frigidaire wall oven models, common failure symptoms (such as a blank or inaccurate display, nonfunctional timers, intermittent resets, or failure to initiate delayed starts), diagnostic checkpoints to isolate the module from power and communication issues, and practical replacement considerations such as connector matching, mechanical fit, and safety precautions (including power disconnection and ESD awareness). The goal is to provide technicians, engineers, and appliance owners with the contextual information needed to evaluate, troubleshoot, and, when appropriate, replace the component safely and reliably.

Function and operational role of the electronic clock/timer in oven control and user interface
The 316455461 Frigidaire Wall Oven Electronic Clock/Timer functions as both a user interface and a timing/control module that coordinates timed cooking functions with the oven’s main control system. Internally it typically contains a display driver, a real-time clock (quartz-based), keypad scanning circuitry and low-voltage logic that communicates with the oven’s main control board; the main board then actuates the high-voltage heating elements or relays. In practice this means the clock/timer reports time, accepts user input for timers, delay-start and timed bake, and transmits those commands via defined pin signals to the primary controller; replacing the module requires a match of connector pinout and firmware compatibility to preserve features and proper control behavior.
- Real-time clock and timer functions for bake/clean/delay-start operations
- User interface components: LED/segment display, keypad scanning, and buzzer outputs
- Low-voltage logic interface to the oven control board and high-voltage switching via relays or SSRs
- Basic diagnostic reporting and retention of timed settings in non-volatile memory
| Item | Description |
|---|---|
| Power | Logic-level supply sourced from the oven control harness (logic typically 3.3-5 V); high-voltage switching handled by relays/SSRs on the main board |
| Interface | Segment/LED display driver, keypad matrix inputs, audible buzzer output |
| Compatibility | Must match connector pinout and control protocol of the oven model; mismatched part numbers can disable timed functions or cause incorrect control signals |
Operationally, the electronic clock/timer is an input/output node rather than a power-switching component: user actions (for example setting a 2-hour timed bake) are captured by the module and transmitted as command flags to the main controller, which enforces safety interlocks and energizes the heating circuits. For diagnostics and repair, technicians should verify the keypad and display operation, confirm presence of the clock’s logic supply voltage, and trace the command lines to the main control; common symptoms of a failing clock/timer include nonresponsive keypad entries, frozen display, incorrect timekeeping, or loss of timed cycles while the main oven functions remain or else normal.
How the 316455461 Frigidaire Wall Oven Electronic Clock/Timer interfaces with power, sensors, and the main control board
The 316455461 Frigidaire Wall Oven electronic clock/Timer functions as the oven’s human-machine interface and timekeeping module; it does not switch high-power elements directly. It connects to the oven via a multi‑pin harness that carries a low‑voltage DC supply and several logic signal lines back to the main control board. The module contains the display drivers, a real‑time clock circuit, and the keypad scan electronics; the control board supplies regulated power and accepts keypad inputs or serial/parallel data from the clock/timer to execute cooking commands. In practice, a dead or dim display almost always indicates a missing DC rail or poor connector contact, while retained time through short power interruptions can indicate an internal backup capacitor or nonvolatile memory on the module itself.
Temperature sensors and high‑power switching remain the duty of the oven’s main control board, so the clock/timer typically shows sensor readings only when the board transmits them; sensor leads (NTC/RTD or thermistor) are usually hard‑wired to the control board rather than to the front‑panel module. Communication between the clock/timer and the control board is model‑dependent and implemented with discrete pushbutton lines, parallel status lines, or a simple serial protocol at TTL levels; compatibility requires matching connector pinout and voltage levels. For troubleshooting and replacement, verify harness voltages with a multimeter, inspect connector pins for corrosion or bent contacts, and confirm the replacement part matches the oven’s connector map and logic voltage to avoid damage to either the module or the control board.
- Blank or flickering display: loss of DC supply or poor connector contact
- Unresponsive keys: broken keypad matrix or failed input lines to the control board
- Clock resets after power loss: failed backup capacitor or missing nonvolatile memory
- Incorrect temperature readout on display: control board sensor fault or communication failure
| Item | Description |
|---|---|
| power | Low‑voltage DC supplied by the main control board (commonly in the 5-12 V range); provides energy for display and clock circuitry |
| Data/Control Lines | Discrete keypad and status lines or a simple serial link that carry user commands and display data between the module and control board |
| Sensor Interface | Sensors (thermistors/RTDs) are generally connected to the main control board; the clock/timer only displays values relayed from that board |
Common failure symptoms and diagnostic indicators of the electronic clock/timer assembly
The 316455461 Frigidaire Wall Oven Electronic Clock/timer provides the user interface for timekeeping, delayed-start functions and timed cook cycles while also supplying status information to the main oven control. Typical failure modes manifest as functional and behavioral symptoms: a blank or dim display, frozen or frequently resetting time, inability to set or start timed bake, audible beeps without response, or intermittent operation where the clock works only after several power cycles. These behaviors often trace to local faults on the module (failed capacitors, cracked solder joints, burned traces), poor connector/harness contact, or loss of the module’s DC supply originating upstream in the oven control electronics.
Diagnosing the assembly requires isolating the clock/timer from other subsystems and confirming compatibility before replacement. Start with a visual inspection and secure connectors, then verify line and low-voltage supplies to the module with a multimeter; measure connector pin continuity and common DC rails to the board rather than relying solely on user-reported symptoms. Replacement units should match the part number and connector layout to ensure compatible firmware and feature support; even visually similar boards can differ in pin assignment or control logic. Common troubleshooting workflow: inspect, verify power, exercise functions with known-good user input, and if available bench-test or swap with a confirmed-working module.
- Blank or dim display – power or display driver failure
- Time resets after power loss – failed backup capacitor or memory retention issue
- Timer will not start/stop oven functions – control interface or communication fault
- Intermittent operation – loose connector, cracked solder joint, or thermal-related component failure
| Item | Description |
|---|---|
| Blank display | Check incoming line voltage and the module’s low-voltage DC rails; inspect backlight/display driver and connectors. |
| Frequent resets | Test for failing backup capacitor or unstable supply; verify continuity on clock backup power pins. |
| timer not actuating oven | Confirm communication between clock/timer and main control board and verify correct pin mapping for replacement parts. |
Replacement considerations and installation procedures, including connector pinouts and calibration
The 316455461 Frigidaire Wall Oven Electronic clock/Timer performs timekeeping, user-interface input scanning, and provides status information to the oven control; it does not directly switch high-current elements in most designs but supplies logic and display functions that the main control board uses to coordinate bake/broil cycles. When replacing this module, confirm mechanical fit, connector style and pin count, and that the replacement part is listed for your oven model; mismatched harnesses or firmware revisions can produce a dark display, unresponsive touchpad, or incorrect timer behavior even though the part physically fits. Preserve harness orientation, photograph connector positions before disconnecting, and follow ESD precautions-static discharge can damage display driver ICs on the module even when the oven is powered off.
- Power off and lock out service power before removing the control panel.
- Photograph and label connectors; verify pin count and keyed shapes against the new part.
- Check continuity and expected voltages at the harness with the power removed and again after controlled re-energization.
- Run the oven’s diagnostics after installation to verify display, key matrix, and communications to the main board.
Installation typically requires removing the trim, releasing two or four mounting screws, unplugging the multi-pin harness and any ribbon cables, and replacing the module with care to seat connectors fully; after reconnection, restore power only to verify display illumination and run a diagnostics/self-test routine. Typical connector pin functions you will verify include line (120 VAC) and neutral feeds for any backlight or heater elements on the module,a ground/chassis reference,a logic supply or reference voltage from the main control,and multiple key matrix or serial communication lines that carry user input and status signals-refer to the oven service manual and use a meter to confirm each signal before swapping boards. Calibration for clocks is minimal (setting time and verifying timer countdown accuracy),while oven temperature calibration is performed at the main control: after replacing the clock/timer,confirm that keypad commands register and that the oven reaches expected temperatures by using an external oven thermometer; if discrepancies persist,adjust temperature offset through the main control’s calibration menu per the service guide.
| Item | Description |
|---|---|
| Pin 1 (Line) | 120 VAC supply for module backlight or heater circuits where applicable – verify before connecting |
| Pin 2 (Neutral) | Neutral return for AC-fed module circuits |
| Pin 3 (Chassis GND) | Ground reference for safety and signal return |
| Pin 4 (Logic V) | Low-voltage reference supplied by main control (often +5 V or similar) for display/ICs |
| Pin 5-8 (Key Matrix / Comm) | Rows/columns of the keypad matrix or serial/data lines used for user input and status exchange with the main board |
Q&A
What is Frigidaire part 316455461 (Wall Oven Electronic Clock/Timer) and what does it do?
Part 316455461 is the electronic clock/timer and user interface module used in certain Frigidaire built‑in/wall ovens. It provides the clock display,kitchen timer,touchpad/buttons for time/oven functions and some display/status feedback. In many models it is the front user interface only; in others it can be integrated with or communicate with the main oven control board to run timed bake functions and display oven status.
What symptoms indicate the clock/timer (316455461) is bad and needs replacement?
Common symptoms include a blank or partially lit display, flickering or scrambled characters, non‑responsive touchpads/buttons, timer/clock functions not working, or error messages that point to the user interface. Also if the timer/clock intermittently works or the display resets on its own,the module may be failing.Before replacing, check power and wiring becuase many “bad display” problems are caused by loose connectors or loss of supply voltage.
How do I check if 316455461 is compatible with my Frigidaire oven?
Confirm compatibility by matching your oven’s full model number (usually on a metal plate inside the oven door frame or on the oven cavity frame) with the part listing. Use Frigidaire/owner parts lookup, an authorized dealer, or the part seller’s compatibility tool. Do not rely only on appearance – the same-looking modules may have different connectors or firmware for different models.
can I replace the clock/timer myself? What are the basic steps and safety precautions?
Yes, a competent DIYer can replace it, but you must take electrical safety precautions. Turn off power at the house circuit breaker or disconnect the appliance from the supply before servicing. Typical steps: 1) Disconnect power. 2) Remove the trim/faceplate screws to access the control module. 3) Unplug the wiring harnesses from the old module (note connector positions or take photos). 4) Remove the module and mount the new one. 5) Reconnect harnesses, reassemble trim, restore power and test. If you are uncomfortable working with live wiring or removing panels, hire a qualified technician.
How can a technician test the 316455461 clock/timer with a multimeter?
Always follow safety practices: power off and verify the circuit is de‑energized before disconnecting connectors. for basic checks: 1) With power off, check continuity of key switches or keypad ribbon (if applicable).2) Inspect connector pins for corrosion or burn marks. 3) With power on (only if you are qualified and careful), measure the supply voltage at the module’s power connector – many Frigidaire clock modules expect 120VAC or a derived low‑voltage feed depending on model; confirm from the wiring diagram for that oven. If the module receives correct supply voltage but the display is dead or buttons do not respond, the module is likely faulty. Refer to the oven’s wiring diagram/service manual for pinouts and expected voltages before measuring live circuits.
Will replacing the clock/timer fix oven heating or element problems?
Not necessarily. The clock/timer is primarily the user interface. If the oven won’t heat but the display and controls respond, the problem is often the main control/relay board, thermal fuse, bake element, or safety thermostat. Though, if the interface is sending incorrect commands or is unresponsive, replacing a failed clock/timer can restore control functionality. Always diagnose whether the issue is user‑interface related or a power/control issue before replacing parts.
How do I reset or program the clock/timer after installing a new 316455461 module?
After restoring power, most modules will either show 12:00 or need you to set the time. Use the clock/time buttons or the oven’s instruction sequence (refer to the model’s owner manual) to set the clock and configure 12/24‑hour mode if available. For timed bake or delayed start functions,follow the oven’s programming steps in the manual. If the module does not accept settings or reverts,recheck wiring and power or consider that the replacement may be defective.
Where should I buy part 316455461 and are aftermarket parts OK?
Buy from Frigidaire dealers, authorized parts distributors, or reputable appliance parts retailers to ensure you get an OEM or properly specified replacement. Aftermarket parts exist, but quality and compatibility vary. Check return policies and warranties. If the appliance is under warranty, use authorized service/parts to avoid voiding coverage.
