316455461 Frigidaire Wall Oven Electronic Clock/Timer is an electronic user-interface and timing assembly used in Frigidaire wall ovens. It is typically a printed circuit board (PCB) module that incorporates a real-time clock, a microcontroller, a visual display (LED or LCD), and the front-panel controls (buttons or touchpads). The assembly may also include low-voltage power regulation and connectors for interaction with the oven’s main control system, and in some designs it can provide switch or relay outputs for timed control functions.
Within the appliance, the electronic clock/timer performs timekeeping, event scheduling and user input handling, and it mediates timed functions such as bake duration, delayed start and auto-shutoff. It interacts directly with the oven’s main control board (or serves as a sub‑controller), the door-lock and safety interlock circuits on models with self‑clean features, and with indicators such as audible buzzers. In normal operation it receives supply power, presents status and error information to the user, and issues control signals to sequencing relays, solid‑state switching devices or the primary control logic that energize heating elements and monitor temperature sensors.
In this article readers will find a technical overview of how the 316455461 clock/timer functions, guidance on model compatibility and how to verify the correct replacement part, common failure symptoms to look for (such as a blank or flickering display, unresponsive keypad, incorrect timekeeping, or failure of timed cycles), step‑by‑step diagnostic checks a technician can perform (power and fuse verification, connector and harness inspection, continuity and voltage measurements, and basic software/firmware reset procedures), and practical replacement considerations including connector pinouts, mounting and ESD precautions, and post‑installation verification.

Function and Role of the Electronic Clock/Timer in Frigidaire Wall Oven Operation
The 316455461 Frigidaire Wall oven Electronic Clock/Timer is the user interface and timing intelligence that coordinates timed cooking programs and provides the time-of-day display.It receives inputs from the keypad, displays status on the LED/LCD, and issues discrete timing signals to the oven’s main control board to start or stop elements according to countdowns, delayed-start schedules, and cook-time limits. The module does not directly switch high-current loads; rather it communicates setpoints and timing events to the main control, which performs the heavy switching and safety interlocks.
- Time-of-day display, countdown/count-up timers, and delayed-start scheduling
- Keypad interpretation and display driver functions
- Low-voltage signaling to the main control board (start/stop and timing interrupts)
- Failure modes that affect oven scheduling but may leave manual bake functions intact
Behavior and compatibility depend on electrical connectors, firmware revisions, and mounting interfaces: replacement with the 316455461 unit requires matching the connector pinout and ensuring the enclosure and ribbon/cable align with the oven chassis. The module’s behavior during power loss varies by design-some units retain settings in nonvolatile memory while others reset-so technicians should verify retained settings after a power interruption.practical symptom examples include a blank or flickering display, unresponsive timer functions, or an oven that will operate manually but will not execute delayed-start programs; these point toward the clock/timer module or its ribbon connection rather then the high-voltage power stage. When diagnosing, confirm proper low-voltage continuity and correct part compatibility before replacing the module.
How the 316455461 Frigidaire Wall Oven Electronic Clock/Timer Interfaces with the Control Board, Sensors, and Power Supply
The 316455461 Frigidaire Wall Oven Electronic Clock/timer is a low-voltage interface module that mounts to the oven door/control panel and connects to the main control board through a multi-pin ribbon or wire harness.Functionally it contains a microcontroller, real-time clock, display drivers, and keypad scanning circuits; the control board supplies a regulated DC reference (typically in the single‑digit volts up to about 12 VDC) and ground, while the clock/timer returns user inputs and status signals. During a timed or delayed bake the module does not switch mains power directly-instead it issues digital enable or “start” commands to the main control board, which performs the high‑voltage relay switching for heating elements. In practice this means the oven may still heat when manually commanded by the main board even if the clock assembly has failed, but timed-cook features, displayed time, and user-key responses will be affected if the clock/timer module is faulty or mismatched to the control board connector/pinout.
Temperature sensors (the oven probe or NTC thermistor) are wired to the main control board and are interpreted ther; however the clock/timer can display sensor-derived values when the control board forwards that data over its bus or mapped signal lines. For troubleshooting and compatibility checks, confirm the replacement module has the same connector pinout, DC supply range, and signaling method (parallel segment drivers, serial data bus, or scanned keypad matrix) as the original part-incorrect replacements can leave the main board unable to recognize inputs or, worse, create voltage conflicts.Practical diagnostics include verifying the low-voltage supply on the clock connector with a DVM, confirming keypad/contact continuity, and observing whether the control board accepts a manual start command from the module; if the module communicates over a serial/data line, checking for expected clock/data toggling with an oscilloscope helps isolate faults.
- Power/ground: regulated DC supply from main board (low-voltage)
- Keypad Inputs: scanned matrix or button lines returned to main board
- Display/Data: segment drivers or serial interface for time/status
- Timer Output: logic-level start/enable signal to main board relays

Common Failure Symptoms and Diagnostic Indicators for the 316455461 Frigidaire Wall Oven Electronic Clock/Timer
The 316455461 Frigidaire Wall Oven Electronic Clock/Timer is a combined user interface and timing control module that manages the oven clock, delayed starts, cook-time countdowns, and the visual display. It interfaces with the main oven control board through a harness and provides both status feedback and control signals; because it integrates display electronics, keypad scanning, and timing logic, failures can manifest as display faults, unresponsive timer functions, or incorrect signaling to the main control that prevents timed events from starting or stopping.
Diagnosing faults focuses on verifying power, connector integrity, and signal continuity: check the module power input (typically 120 VAC on many Frigidaire wall ovens), inspect the harness for corrosion or push-pin damage, and confirm the module retains settings after a power interruption. practical tests include measuring the supply voltage at the module pins, checking for continuity of any inline fuses, and exercising the keypad while monitoring the control board inputs with a multimeter or logic probe; because firmware and pinouts vary between oven models, replacement requires the correct part number to ensure compatibility and avoid mismatched signals.
- blank or dim display – loss of power,failed display driver,or backlight failure
- Flashing or garbled digits - internal timing oscillator or processor fault
- timer not initiating/stopping cooking - missing control signal to the main board or failed relay control output
- Loss of clock memory after power outage – failed internal backup capacitor or memory circuit

Compatibility Matrix,Replacement Considerations,and professional Installation Guidelines
The 316455461 Frigidaire Wall Oven Electronic Clock/Timer is the user-interface module that provides timekeeping,countdown/timer functions,and the display/touchpad interface between the user and the oven’s main control board. Compatibility depends on mechanical mounting, connector pinout, and the control-board firmware; identical visual appearance does not guarantee electrical or firmware compatibility. Technicians should confirm the exact part number and cross-reference the oven model and control-board revision in the service manual before replacing the unit. Common incompatibilities include different display technologies (LED vs. VFD), mismatched ribbon or harness pin assignments, and differences in the low-voltage supply and signal mappings coming from the main control board.
For replacement and installation, treat the clock/timer as an integral control module: verify the replacement matches the original part number and connector type, remove power to the appliance, document wiring and connector orientation, and inspect the harness for corrosion or damage.Practical installation steps include photographing connections before disassembly, using ESD precautions on exposed PCB pins, and performing a controlled power-up test with the oven idle to confirm basic functions (display, time set, and basic keypad responses) before full operational checks. If error codes persist after replacement, re-check pinouts and control-board compatibility or consult the equipment-specific wiring diagram.
- Pre-replacement checklist: confirm part number,compare connector pinout,document wiring,isolate mains power,and verify physical mounting depth.

Q&A
What is part number 316455461 for a Frigidaire wall oven?
Part number 316455461 is the electronic clock/timer control assembly used on a range of Frigidaire wall ovens. It contains the digital display and timer/clock electronics and is responsible for displaying time, accepting timer and bake/clean programming inputs, and communicating with the oven’s main control circuitry.
How do I know if the clock/timer (316455461) is bad or if the problem is elsewhere?
Common symptoms of a failing clock/timer include a blank or flickering display, unresponsive touchpad/buttons for clock or timer functions, or the oven failing to respond to timed bake/clean commands. Before replacing the part, verify there is proper power to the control (check house breaker and any oven fuses), inspect the ribbon/connector for damage, and test for obvious wiring or connector faults. If the display is blank but the oven heats, the clock assembly is highly likely the issue; if the oven won’t heat at all, the problem could be the main control board, thermal fuse, or central power feeding both modules.
Can I replace the 316455461 clock/timer myself, and what safety steps should I follow?
Yes, experienced DIYers and technicians can replace the clock/timer, but always disconnect all power to the oven first by switching off the circuit breaker or unplugging the appliance. After power is off, remove the control panel trim/screws to access the clock assembly, unplug the wire harnesses or ribbon cables, and note the connector orientation before swapping parts.Reinstall in reverse order and restore power to test. if you’re not pleasant working with live electrical wiring or disassembling the panel, hire a qualified appliance technician.
How do I test the clock/timer if the display is blank?
With power disconnected, inspect the control board, connectors, and ribbon cable for physical damage or corrosion. If you have a multimeter and the service manual/schematic, you can check that the board is receiving the correct supply voltages with power applied (follow safety precautions and only do live voltage checks if qualified). Also check oven and line fuses or thermal cutouts that would remove power from the control. If the board receives correct voltages but has no display and no keypad response, the clock/timer assembly is likely defective and should be replaced.
How do I set or program the clock/timer after replacing part 316455461?
Procedure varies slightly by model, but generally: press the “Clock” or “set Clock” pad, enter the current time using the number pads or up/down pads, then press “Clock,” ”Start,” or ”Enter” to confirm. For the kitchen timer, press “Timer,” enter the duration, and press “Start” or ”Timer” again. If unsure,consult your oven’s user manual for the exact button sequence for your model.
Will replacing the clock/timer fix error codes related to timing or the display?
Replacing a faulty clock/timer will resolve errors that are specifically due to the clock/timer electronics (for exmaple, display failure or unresponsive timer functions). However, some error codes are generated by othre modules (main control board, temperature sensors, etc.). Always confirm the error code meaning in the service manual and troubleshoot the associated circuits before assuming the clock/timer is the sole cause.
How do I confirm compatibility of 316455461 with my frigidaire oven model?
Check the oven’s model number (usually on a label inside the door frame or on the back) and cross-reference it with parts lists from Frigidaire or reputable parts suppliers. Search the part number 316455461 against your model number or consult Frigidaire customer service or an authorized parts dealer to ensure the part is a direct replacement for your specific wall oven model.
Are there any tips for installing the replacement to avoid problems afterward?
Before final reassembly, reconnect the clock/timer and power up the oven to verify the display and buttons work and that the oven responds to basic commands. Make sure all wire harness connectors and ribbon cables are fully seated and that ribbon cables are not pinched when reinstalling trim. Keep screws and metal trim free of contact with circuitry. If functions are still erratic after installation, re-check connector seating and wiring continuity; if necessary, compare connector voltages to the service manual to confirm correct installation.
