137006085 frigidaire Washer Control Board is a printed circuit assembly that functions as the primary electronic controller for compatible Frigidaire washing machines. As a central control module, the board typically contains a microcontroller or logic ICs, power regulation components, driver stages (relays, triacs or MOSFETs)and connector interfaces for the user controls and wiring harness; it governs timing, mode selection and the execution of machine cycles.
Inside the appliance the control board coordinates inputs from the user interface and sensors (door or lid lock, water level/pressure switch, temperature sensorsand door interlocks) and issues outputs to actuators such as the wash motor, drain pump, water inlet valves and heaters where fitted. It also implements safety interlocks, error detection and sometimes diagnostic signalling; electrically it sits between the mains-derived power supply and low-voltage control circuitry and between sensor inputs and power-stage outputs, translating logical commands into switched power to subsystems.
In this article readers will find a technical overview of the 137006085 board’s functional blocks, guidance on verifying compatibility with specific washer models and harnesses, common failure symptoms (for example no power, unresponsive controls, cycle non‑advancementor specific error codes), and systematic troubleshooting steps including visual inspection, basic voltage checks and connector verification. The article will also cover practical replacement considerations such as handling ESD-sensitive components, ensuring correct harness and firmware/selector settings where applicable, and verifying safety and grounding after installation.

Functional Role of the Washer Control Board: Control Logic, Power Distributionand Safety Interlocks
The 137006085 Frigidaire Washer control Board is the printed circuit assembly that implements the machine’s control logic and coordinates inputs from sensors, user controlsand actuators. It typically contains a microcontroller running cycle algorithms,driver stages for the drive motor and water valves (triacs,MOSFETs or relays),and interfaces for level,temperature,and door/lid sensors. Technicians should treat the board as both a command processor and a signal translator: it converts low-voltage sensor signals into timed control outputs and fault codesand requires the correct harness pinout and firmware variant to be functionally compatible with a given washer model and motor type. Practical examples include PWM control of a variable-speed motor during spin profiles, timed energization of inlet valves for fill controland interpretation of a rotor tachometer or hall-effect sensor to regulate spin speed and detect stalled conditions.
Power distribution and safety interlocks are grouped on the board to isolate hazardous line-voltage switching from the low-voltage logic and to enforce protective shutdowns. Incoming mains is routed through fuses, surge suppressionand switching devices on the board so that outputs to the heater, drain pumpand motor are only powered when safety conditions are satisfied. Safety interlocks such as the lid/door lock, water-level switch, and thermal cutouts are hardwired to inhibit drive or heating outputs and to generate fault states when triggered; a failed interlock or a burned relay trace will present as specific symptoms rather than random behavior. Common diagnostic checks include verifying presence of standby voltage on the board, continuity of harness circuitsand visual inspection for lifted traces or failed components; replacing the board without confirming matching connectors and firmware may not resolve issues caused by harness faults or external components.
- No motor/drive response while console lights indicate power - check relay/triac outputs and motor tachometer input.
- Fills but does not agitate or spin - inspect valve control outputs, drive relaysand lid/door lock circuit continuity.
- Heater does not energize though cycle requests heat – verify heater relay, mains feed through board, and thermal cutoff status.
- Error codes or blinking LEDs - consult model-specific diagnostics to map blink patterns to failed inputs/outputs.

How the 137006085 Frigidaire Washer Control Board works Inside the Appliance: Interfaces, Signal Flowand firmware Control
the 137006085 Frigidaire Washer Control Board is the appliance’s central printed circuit assembly that translates user selections and sensor inputs into timed actuator commands.Internally it contains a low-voltage power supply and regulator for the microcontroller, input conditioning circuits for thermistors, pressure switches, door-lock switches and tachometer pickupand mains switching stages (relays, triacs or MOSFETs) for the pump, valves and motor.Signal flow typically begins at the user console or door interlock, continues to the microcontroller which evaluates water level and temperature inputsand then sequences outputs to the fill valve, drain pump and motor. For example, during a wash-to-spin transition the controller verifies the lid/door locked state, energizes the drain pump, monitors the tachometer pulses to confirm motor rotationand adjusts drive timing or phase control to reach the commanded spin speed; technicians should confirm harness pinouts and model compatibility prior to swapping boards as connector arrangements and mains switching components vary between Frigidaire models.
- User interface and console commands (start/pause, cycle selection)
- Sensors: tachometer pulses, water-level/pressure switch, temperature thermistor
- Actuators: drain pump, fill valves, motor drive stage, door lock
- Power: mains input, fused protection, low-voltage regulator for logic
- Diagnostics: status LED blink codes, stored fault counters, EEPROM calibration
| Item | Description |
|---|---|
| Microcontroller | Executes firmware state machine, timers, ADC sampling and fault handling |
| Motor driver | Triac/MOSFET stage or relay interface with tach feedback for speed control |
| Sensor conditioning | Resistive divider and filtering for thermistors/pressure lines and debounced digital inputs |
Firmware on the board implements an event-driven state machine with safety interlocks, watchdog supervision and non-volatile storage for calibration values and service codes; timing, PWM or phase-angle control is used to manage motor torque and speed depending on the motor type and drive circuitry. Practical troubleshooting steps that interact with both hardware and firmware include verifying the low-voltage rail (commonly 5 V or 3.3 V), checking for shorted output stages or blown fuses, measuring tachometer pulse frequency during motor operationand reading console fault codes or LED blink sequences to narrow failures to sensor, actuatoror firmware-managed timeout conditions. Replacement or repair should follow wiring verification and, when available, cross-reference the machine model and wiring schematic to ensure the 137006085 board’s connectors and firmware behavior match the appliance configuration.
Common Failure Symptoms and Diagnostic Indicators (Error Codes, No-Start, and Erratic Cycles)
The 137006085 Frigidaire Washer Control Board manages logic, sensor inputsand power switching for motors, valves, and the user interface; failures on this board commonly present as displayed error codes, a complete no-start conditionor erratic cycle behavior such as unexpected stops, incorrect fill levelsor intermittent spinning. Technically, these symptoms arise when the board’s voltage regulators, MOSFET/relay outputsor communication pathways fail to provide stable reference voltages or reliable drive signals.Practical indicators include a lit console with no drum activity (power to the UI but no motor drive), repeating error codes for diffrent subsystems, audible rapid clicking from the relay areaor visible damage on the PCB such as burned traces or bulging capacitors. Visual inspection combined with basic electrical checks-confirming line voltage at the board, verifying 5V/3.3V logic railsand checking ground continuity-will quickly separate harness/sensor issues from a failed control board.
- No-start with console power (check door/lock, AC input fuseand board power regulator)
- Persistent or changing error codes (check communications lines, stored fault history in service mode)
- Erratic cycles or intermittent operation (inspect motor tach feedback, water level/pressure switchand connector continuity)
- Audible clicking or repeated relay chatter (suspect output driver MOSFETs, relaysor shorted loads)
- Visible PCB damage or corrosion (often definitive for board replacement)
Diagnosis should proceed by isolating subsystems: read the washer’s service diagnostic codes, measure DC supply rails on the control boardand confirm expected switching at output terminals under commanded cycles using a multimeter or oscilloscope. Replacement compatibility requires the identical board part number and matching connector pinouts and firmware expectations; substituting a visually similar board without verifying harness layout can leave sensors and pumps uncontrolled. If a replacement 137006085 board is installed and symptoms persist, systematically test the motor, door-lock assembly, level sensorand harness continuity as intermittent sensor feedback or wiring faults can mimic board failures.
| Item | Description |
|---|---|
| No-start | Check AC input, board power regulators, door lock signal, and main relay/MOSFET outputs for expected voltage |
| Erratic cycles | Inspect tachometer/motor feedback, water-level sensor, loose connectorsand intermittent component heating/failure on the PCB |
Compatibility, Replacement Considerationsand Step-by-Step installation Procedures for the 137006085 Frigidaire Washer Control Board
The 137006085 Frigidaire Washer Control Board functions as the appliance’s central logic moduleorchestrating the user interface, motor control, valve sequencing, sensor inputsand safety interlocks. Compatibility is determined by the board’s part number, PCB revision, firmware versionand the mechanical/electrical interface of the harness and mounting points. Technicians should compare the printed part number and revision codes on the replacement board to the original,verify pinouts against the washer’s wiring diagram,and inspect for matching connector types; two boards that look mechanically identical can have incompatible firmware or different relay/triac ratings that affect motor or heater control. Typical failure symptoms that indicate a control board issue include unresponsive touchpad or selector switches, failure to advance cycles, intermittent pumps or motorsand persistent error codes that do not clear after power cycling. Before ordering a replacement, examine the original board for water damage, scorched tracesor failed capacitors and confirm whether any accessory modules (display, door lockor inverter) are integrated or separate components that must be transferred or replaced together.
- Safety and preparation: disconnect mains power and unplug the washer; document connector locations with photos and label harnesses to preserve wire routing.
- Access and removal: remove the rear or top control panel, loosen mounting screws/standoffsand carefully release ribbon cables and multi-pin plugs – avoid pulling on wires directly.
- Transfer and installation: move any configuration jumpers,standoffs,or thermostat leads to the new board,seat the PCB on its standoffs,and fully engage all connectors until tactilely locked.
- Verification: restore power, enter the washer’s diagnostic or service mode per the service manual to check LED indicators and run actuator/motor tests, then perform a short test cycle while monitoring for errors and leaks.
Follow ESD precautions and use insulated tools when handling the board; a common troubleshooting practice is to power the unit on with the chassis still open while observing which relays or status LEDs activate to isolate faults. If the replacement board passes initial diagnostics but intermittent faults persist, verify upstream components such as door switches, motor start capacitors, tachometer/generator signalsand mains supply stability because spurious inputs can cause the control to behave erratically. After successful installation, document the new part number and any firmware or jumper settings in the service record to ensure future maintenance and parts ordering align with the installed configuration.

Q&A
What is the 137006085 Frigidaire washer control board and what does it do?
The 137006085 is the electronic main control (PC board) used in certain Frigidaire top‑load washers.It coordinates user inputs, runs the wash cycles, controls the motor, valves, pump and heater (if present)and interprets signals from sensors (door lock, water level, temperature). If it fails,the washer can exhibit symptoms such as no display,unresponsive controls,or incorrect cycle behavior.
How can I tell if the 137006085 control board is bad or something else is causing the problem?
Common signs of a failing control board include: no display or lights while other components receive power, unresponsive buttons, random or incorrect cycles, failure to start while power is presentor obvious burn damage on the board. Before replacing the board, check power at the outlet, verify main fuses and door lock, inspect wiring harness and connectors for burns or corrosionand test related components (motor, lid/door switch, water valves) because those faults can mimic board failure. Visual inspection for burnt components, bulging capacitorsor scorch marks on the board is also important.
What basic tests can a technician perform to diagnose the 137006085 board?
Start by unplugging the washer and visually inspecting the board. With the machine unplugged, check harness connectors for heat damage. With the washer powered (take safety precautions), verify incoming line voltage to the board (typically 120 VAC in the U.S.). Measure the board’s low‑voltage supply rails (refer to the service/wiring diagram for expected voltages – commonly 5 V or 3.3 V for logic and 12-24 V for some relays).Check continuity of fuses on the control boardand monitor outputs when a cycle is selected (e.g., whether the board is commanding the motor relay, drain pumpor valves). Use the service manual or wiring diagram for pinouts and expected signals. If the board fails to provide expected outputs while inputs are correct,the control board is highly likely defective.
Is the 137006085 a direct drop‑in replacement and how do I confirm compatibility?
Replacement boards are often model‑specific.Confirm compatibility by matching the exact Frigidaire part number (137006085) to your washer’s model number and the board’s revision printed on the PCB. Check the washer’s model number on the cabinet tag and consult the Frigidaire parts diagram or a reputable parts supplier. do not assume physical similarity equals compatibility-some boards require a specific connector layout or firmware for a given model.
what are the safety steps and basic procedure to replace the 137006085 board?
Unplug the washer before starting.Take clear photos of wiring and connector positions so you can reconnect everything correctly. Ground yourself to avoid static damage, remove the control console or rear panel to access the board, disconnect harnesses one at a timeand remove mounting screws. Transfer any standoffs, jumper wiresor interlocks from the old board if required. install the new board, reconnect harnesses, restore power and run diagnostic or a short cycle to verify operation. Do not touch high‑voltage components while the unit is plugged in – some parts can retain charge.
Do I need to program or initialize the 137006085 board after installation?
Most Frigidaire main control boards are plug‑and‑play and do not require user programming; the replacement should work instantly once correctly connected. Some models may require a clear or reset procedure (power cycle or entering a diagnostic mode) – check the service manual for your model. If the washer has a user interface or EEPROM that stores settings, ensure the replacement board’s configuration matches the washer model. When in doubt, consult the service documentation or the supplier.
How much does a replacement 137006085 board cost and where can I buy one?
Price varies by supplier and whether the part is OEM or aftermarket; typical ranges (at time of purchase variability) can be roughly $80-$300.You can purchase the board from Frigidaire authorized parts dealers,appliance parts websites,or online marketplaces. Buying OEM parts from reputable suppliers and checking return/warranty policies is recommended. If a repair shop supplies and installs the board, labor will increase the total cost.
Does the board come with warranty and are there common causes that make it fail?
Warranties depend on the seller – many parts suppliers offer 90 days to 1 year limited warranties on control boards; OEM factory warranties may differ. Common causes of control board failure include power surges, lightning strikes, failed components (capacitors, MOSFETs, relays), water intrusionand overheating from nearby failing parts. To reduce recurrence, ensure proper grounding, protect the appliance from power surgesand address root causes (e.g., a failing motor that draws excessive current) rather than only replacing the board.
