318185341 Frigidaire Oven Timer Clock is an electronic clock and timer assembly used in Frigidaire ranges and ovens. It serves as the user-facing timekeeping and scheduling component, typically incorporating a digital display, keypad or touch interface, and timing logic. Physically the module is mounted behind the control panel and connects to the appliance wiring harness; depending on the model it may use an LED or VFD display and standard multi-pin connectors for power and signal lines.
Within the appliance, the timer/clock provides time-of-day display, audible alerts and timed control functions such as delayed start, cook timers and self-clean sequencing. It interacts with the main control board and related subsystems by issuing start/stop or enable commands and by displaying status to the operator. The timer typically does not sense oven temperature directly but relies on inputs from the temperature sensor and safety interlocks; it can, though, initiate or inhibit heating circuits, fan motors and door locks through the control board’s relays or power switching devices and by communicating error or status conditions to other control logic.
This article will explain the technical function of the 318185341 timer/clock, how to verify compatibility and identify the correct replacement, common failure symptoms (such as blank or flickering display, inaccurate or non‑functional timers, unresponsive keys, or timed cycles that fail to start), basic troubleshooting procedures to isolate the module from power and control‑board faults, and practical considerations for safe replacement and reassembly. Emphasis will be on diagnostic steps, connector and voltage checks, and criteria for deciding whether to replace the timer unit or pursue repairs elsewhere in the control system.

Function and Role of the Oven Timer Clock within Frigidaire Control Architecture
The 318185341 Frigidaire Oven Timer Clock functions as both the user-facing timekeeper and the timing control interface between the user and the ovenS main control board. It provides real-time clock display, countdown/timed-cook functions and the delay-start logic that tells the power relays and heating elements when to energize or de-energize. In practice the module monitors inputs such as user key-presses, door-closed signals and simple status flags from the bake/broil relays, and outputs discrete timing commands and status lines to the main controller. If a timed bake is programmed (such as, 45 minutes at a set temperature), the timer keeps the countdown and issues the stop command at zero; during power interruptions, stored settings might potentially be preserved in non‑volatile memory on some assemblies, while others will lose volatile settings and require reprogramming after extended outages.
- User interface and real-time display for scheduled operations.
- Generation of timing control signals to the main control board or relay drivers.
- Monitoring and reporting of basic oven status (timer complete, delay active, etc.).
- Interfacing via specific harness connectors and signal protocols-verify pinout before replacement.
Compatibility of this clock with a given oven depends on matching the electrical connector, mounting points and the control protocol used by the appliance’s main board; technicians should compare connector pinouts and any model-level service documentation before installing a replacement. common failure symptoms attributable to the timer clock include a blank or unresponsive display,inability to set or retain cook timers,or intermittent start/stop of timed cycles; basic diagnostics include verifying supply voltage at the module connector,inspecting the harness for corrosion or broken pins,and substituting a confirmed compatible module to isolate the fault. The table below summarizes key technical reference points for field service.

How the 318185341 Frigidaire Oven Timer Clock works Inside the Appliance: Electrical Interfaces, Firmware behavior, and Signal Flow
The 318185341 Frigidaire Oven timer Clock functions as the user-facing real‑time clock, keypad interface, and timing controller that communicates with the oven’s main control board.Electrically, the module typically receives low-voltage DC power and a neutral/line reference from the appliance harness while exchanging digital control and status lines with the main board via a multi‑pin connector; some variants also include a directly switched 120 VAC line for the display backlight or buzzer. The on‑board firmware implements a real‑time clock, display multiplexing, keypad debouncing, and a compact state machine that generates time‑up events, chimes, and timed control signals; those firmware behaviors determine whether the module merely reports timer events to the main controller or actively drives an output that enables a relay/triac for audible or illumination functions. When replacing the module, confirm connector pinout, supply voltages, and firmware/region variants to ensure compatibility and predictable behavior in the oven’s control ecosystem.
Signal flow through the assembly follows a clear sequence: user keypress → MCU processes input and updates the RTC/display → internal timer expires → MCU asserts an output line (logic pulse or drive waveform) → main control board interprets the event or a local driver energizes a buzzer/relay. For troubleshooting, technicians usually check the presence of the supply rail(s) at the module connector, verify data lines for activity with a logic probe or oscilloscope, and measure the output pin when a timer is triggered; for example, a pulse on the designated “timer output” pin concurrent with a buzzer fault helps isolate whether the firmware is signaling correctly but the downstream driver is failed. Practical diagnostics and repairs should target connector continuity, expected DC rails (commonly 5-12 VDC for the module logic), the presence of a neutral/line for any AC‑powered subfunctions, and visual inspection of the ribbon/PCB for cold solder joints or corrosion.
- Power rails: low‑voltage DC for MCU and optional 120 VAC feed for certain outputs
- Communication: serial/data and clock lines or discrete logic status pins to main board
- Outputs: buzzer/chime drive, lamp/illumination control, timer-expire signal to controller
- Inputs: keypad matrix, door/latch status lines, manual reset or cancel
| Item | Description |
|---|---|
| Power input | Low-voltage DC from main board (typical 5-12 VDC); some boards also accept AC for lamps/buzzer |
| Control signals | Digital lines (serial or discrete) used to report timer events and accept commands from the main controller |

Common failure symptoms and Diagnostic Indicators for the Timer/Clock Assembly
The timer/clock assembly in manny Frigidaire ranges controls the user interface, the digital display, and the timing signals that tell the oven control to energize the bake/ broil circuits. The 318185341 Frigidaire Oven Timer Clock provides the display and pushbutton inputs and routes timing/start signals to the main control; when it functions correctly it maintains time, counts down, and closes the appropriate start circuit for delayed or timed cooking. Compatibility is determined by connector pinout and mounting – some model variants use a separate electronic oven control that expects specific logic-level outputs,while others rely on the clock assembly to switch line-level power. A practical example: if the oven heats normally when set directly at the control but will not start a timed cook, the fault is frequently enough isolated to the timer/clock assembly failing to provide the start output rather than the bake element or temperature sensors.
- Blank or dim display while oven has power
- Intermittent or frozen timekeeping (clock stops or resets)
- Touchpad/buttons unresponsive or erratic inputs
- Timed start/countdown does not initiate oven operation
- Partial segment failures or blinking segments on the display
- Burnt smell, visible corrosion, or damaged connector pins
| Item | Description |
|---|---|
| display blank | Check incoming supply and connector voltage; inspect for blown internal fuse or damaged power traces. |
| Timed start fails | Verify the clock outputs a start signal when countdown reaches zero (use meter to detect continuity or control output pulse to the main board). |
| Buttons not responding | Test keypad continuity and check for moisture or corrosion at the ribbon connector; if connector and power are present, the assembly may require replacement. |
Effective diagnosis proceeds from visual inspection to electrical verification: look for damaged traces, burnt components, or loose harnesses, then measure for the expected supply voltage at the assembly connector and confirm whether control outputs are present when commands are given. Use a multimeter to observe whether the clock produces a switching output or voltage pulse to the oven control at the end of a countdown; if the assembly receives the correct supply but does not produce the expected output, the failure is within the clock/timer module rather than the main control. In contrast, if the assembly has no power, trace the feed back to the line, fuses, and door interlocks; replacing the 318185341 Frigidaire Oven Timer Clock is warranted when the unit fails internal tests or shows physical damage, but mismatched pinouts or model variants must be confirmed before installation to avoid compatibility issues.
Compatibility, Replacement Considerations, and Step-by-Step Installation Procedures for Frigidaire Models
The 318185341 Frigidaire Oven Timer Clock is the control module that provides timekeeping, user-input decoding, and timed-cook functions while interfacing with the oven’s main control board.It displays the clock and timer, accepts keypad commands (delay start, cook time, timer), and issues control signals to relays or triacs on the main board; therefore compatibility is determined by electrical interface and mechanical mounting rather than only cosmetic fit. Technicians should confirm the part number, connector pinout, and mounting footprint against the oven’s service sheet or wiring diagram; mismatched pin assignments or different operating voltages can prevent proper operation or cause damage.Such as, a module that uses a 7-pin keyed harness and 120 VAC clock supply will not interchange with a unit that uses a ribbon cable and communicates digitally with the main board without an adapter or board change.
For safe replacement and reliable operation follow a controlled procedure: disconnect power at the breaker, verify presence/absence of expected voltages with a meter, transfer any mechanical brackets or bezel from the old module, and confirm harness orientation before reconnection to avoid reversed pin connections. After mechanical installation and connector mating, restore power and run verification tests – set the clock, run a timed bake, and observe that the oven cycles (bake/broil) and display timers respond correctly; note any fault codes and recheck wiring if alarms persist. Handle ribbon and multi-pin connectors carefully to avoid bent pins or damaged insulation; static-sensitive electronics should be handled using grounding precautions.
- Power off at breaker and verify zero voltage on control harness.
- Remove control-panel screws, lift panel to access module, and document connector orientation.
- Disconnect harness(es) and transfer mounting hardware to new unit.
- Install new 318185341 Frigidaire oven Timer Clock,reconnect harness with correct keying,and secure panel.
- Restore power and perform clock/timer and oven function tests; record any error codes for further diagnosis.

Q&A
What is Frigidaire part 318185341 and which appliances use it?
Part 318185341 is an OEM electronic clock/timer control module used on a range of Frigidaire electric ovens and some affiliated-brand ranges.it provides the oven clock, timer functions and user interface for oven controls. It is used in a variety of models; always confirm compatibility by matching the part number to your appliance model number (found on the oven frame or behind the lower drawer) or by checking an official parts list.
How do I know if the clock/timer module (318185341) is bad or if something else is causing the problem?
Common symptoms of a failed module are a blank display, non-responsive clock/timer buttons, or error messages related to the control. To isolate the module: first verify the oven has power (check breakers), then check for 120 VAC (or the expected line voltage) at the control board power connector with a multimeter. If the control is getting proper supply voltage but the display remains blank or unresponsive, the module is likely faulty. If there is no voltage at the connector, the problem may be a tripped breaker, blown thermal fuse/oven fuse, or wiring issue upstream of the control.
Can I replace the 318185341 myself, and what safety precautions should I take?
Yes, a competent DIYer can replace this module, but always prioritize safety.Turn off power to the appliance at the house circuit breaker (do not just rely on the oven’s controls). Verify power is off with a non-contact tester or multimeter. Use insulated tools, avoid touching energized wiring, and discharge capacitors only if you know the correct procedure. If you’re unsure about working with high voltage or appliance disassembly, hire a qualified appliance technician.
What are the basic steps to replace the Frigidaire 318185341 clock/timer module?
Typical replacement steps: 1) Cut power at the breaker and verify removal. 2) Remove the backguard or control panel trim (screws or clips) to access the module. 3) Take a photo of the wiring or label each harness for reassembly. 4) unplug the control’s wiring harness and any connectors, then remove mounting screws and pull out the faulty module. 5) Install the new module, reconnect the harnesses, reattach the panel, restore power and test. Exact access steps vary by model,so consult the service manual or parts diagram for your oven.
why does the clock reset after a power outage and how do I fix it?
Most oven clocks/controls do not have a long-term battery backup; they rely on the house power, or a small internal capacitor for brief outages. If the clock resets after every outage (even short ones) it may indicate a failed internal capacitor or other fault in the control module. Replacing the control module (318185341) typically resolves persistent resets. For single, expected resets after longer outages, this is normal behavior.
My oven display is partially lit or has missing segments-does this mean the 318185341 is defective?
Partial displays can be caused by a failing display/LED driver within the control module,a poor connector,or intermittent wiring. First power-cycle the oven and reseat the connector(s). If the symptom persists with proper connector seating and steady power present, the control module’s display section is likely failing and replacement is recommended.
After installing 318185341 the oven won’t heat or shows error codes-what should I check?
After replacing the clock/timer, verify all wiring harnesses are fully seated and no connectors were left disconnected. Some ovens require a specific diagnostic reset or to be put back into normal mode after the control replacement-consult the service manual. If the oven still won’t heat, check for other faults (bad bake/element, thermal fuse, relays on the control board) and note any displayed error codes; those codes help identify whether the control is communicating with the oven’s power components or if another part has failed.
Where can I order a genuine 318185341 module, and is a used or aftermarket part acceptable?
order OEM 318185341 from authorized Frigidaire parts dealers, major appliance parts websites, or directly from the manufacturer’s parts department. Genuine OEM parts offer the best compatibility and reliability. Aftermarket or used parts can be less expensive but may not provide the same longevity or might be incompatible with firmware variations-use them cautiously and verify return policies and warranties.
