137353300 Frigidaire Washer Lid Lock Switch is an electromechanical interlock assembly used on Frigidaire washing machines to detect lid position and, when required, mechanically lock the lid during certain cycle phases. the component typically combines a contact switch and a mechanical latch or solenoid in a compact module that mounts to the cabinet where the lid engages the striker, providing both a physical lock and an electrical status signal to the machine’s control system.
Inside the appliance the lid lock switch serves as a safety and control interface between the lid mechanism and the washer’s control electronics. It provides a discrete input to the control board indicating whether the lid is closed and, on models with an active lock, it energizes the latch to prevent the lid from opening during agitation or high-speed spin. The switch thus interacts directly with the main control board, motor drive or relay circuits, and any lid-actuated interlock logic, and it must reliably transmit both mechanical engagement and electrical continuity to maintain correct cycle sequencing and to prevent unsafe operation.
In this article readers will learn how the 137353300 lid lock switch functions electrically and mechanically, how to verify compatibility with specific Frigidaire models, common symptoms of failure (such as refusal to start, inability to enter spin mode, or lid-related error indications), and practical troubleshooting steps including visual inspection, continuity and voltage checks at the connector, and mechanical inspection of the latch. The article will also cover replacement considerations-matching part numbers and connectors, correct mounting orientation, basic safety precautions (power disconnection before service), and post-installation checks to confirm the lock and the control logic are operating as intended.

Function and Role of the Lid Lock Switch in Frigidaire top-Load Washers
The 137353300 frigidaire Washer Lid lock Switch is an electromechanical interlock that provides both a mechanical latch and an electrical feedback circuit to the washer control board. When the control board commands a cycle that requires the lid to be locked (for example, high-speed spin), the assembly actuates a latch and closes internal switch contacts so the controller receives a “lid closed/locked” signal. The part combines a solenoid or actuator and one or more microswitches in a single housing; compatibility depends on matching the housing mounting points, connector pinout, and switch logic to the specific Frigidaire/top-load control board. in practice, a correct replacement must reproduce the original connector arrangement and feedback wiring so the controller interprets the lock state reliably rather than only matching the external appearance.
Faults in this assembly typically present as a washer that will not advance to spin, gives lid or interlock error codes, or reports an open/closed status that does not change when the lid is manually moved. Technicians diagnose the unit by verifying that the actuator physically moves and that the switch contacts change state with a multimeter (continuity or resistance) while operated, inspecting the wiring harness and connector for corrosion or broken wires, and confirming the control board provides the expected actuation voltage or signal.Practical examples: a machine that drains and then refuses to spin frequently enough shows an open circuit on the lock feedback line,while one that intermittently unlocks during spin may have a fatigued latch spring or worn actuator cam.
- Common symptoms: washer won’t start, won’t enter spin, lid lock error codes, intermittent lock/unlock behavior
- Quick checks: verify actuator movement, measure continuity on feedback pins when locked, inspect connector and harness integrity
- Replacement note: match mounting tabs and connector pinout, not just the external housing, to ensure proper operation

How the 137353300 Frigidaire Washer Lid Lock Switch Works Inside the Appliance: Electrical and Mechanical Interaction with Control Boards and Safety Interlocks
The 137353300 Frigidaire Washer Lid Lock Switch functions as both a mechanical latch and an electrical feedback device that the washer’s control board uses to enforce the door-interlock safety sequence. Mechanically, the component contains a spring-loaded latch or solenoid that holds the lid closed during agitate and spin phases; electrically it contains one or more switch contacts (often implemented as a small microswitch or contact array) that change state when the latch is engaged. When the lid is closed,the switch provides a “locked” signal to the control board; when the latch does not seat or the contacts fail,the control board will inhibit motor start or transition to spin to prevent unsafe operation. The part mounts to the washer cabinet and mates with a matching harness so that both the coil/latch and the feedback contacts connect directly to the machine’s harness without aftermarket adapters in compatible models.
From an electrical standpoint the lock switch is typically a low-voltage or dry-contact input to the main control board while the latching mechanism itself may be driven by the board through a seperate power line; the board monitors the contact state and current draw to distinguish normal operation from a fault (for example, a stuck latch, shorted coil, or open contact).In practice, technicians verify behavior by measuring continuity between the defined contact pins with the lid closed (expecting a closed circuit for the “locked” contact) and by observing that the control board supplies drive only during the lock phase; symptoms such as a constant humming from the lock, persistent lid-locked error codes, or a washer that will not advance to spin typically indicate either a failed switch contact or a mechanically jammed latch. Practical troubleshooting often includes checking the connector for corrosion, verifying continuity of the feedback contacts, and confirming the control board is supplying and sensing the appropriate drive and feedback signals before replacing the lock assembly.
- Common symptoms: no spin, lid-locked error code, continuous actuator noise, or lid that will not latch.
- Typical tests: visual inspection, connector pin continuity with lid closed, and checking for drive voltage/current from the control board during a lock cycle.
- Compatibility considerations: ensure harness and mounting points match the washer model to avoid miswired feedback or incorrect latch orientation.

Common failure Symptoms and Diagnostic Indicators of Lid Lock Switch Malfunction
The 137353300 Frigidaire Washer Lid Lock Switch is an electromechanical interlock that secures the lid and signals the washer control board that the lid is properly closed before high-speed agitation or spin. The assembly combines a mechanical latch with one or more microswitch contacts; the control board supplies a lock command and then monitors the switch state to confirm engagement. Compatibility depends on both the harness pinout and the physical latch geometry, so replacements must match the original part’s mounting points and connector orientation to ensure reliable engagement and correct signalling to the washer’s control logic.
Common failure modes produce distinct, testable indicators. Typical symptoms include a machine that will not start,a persistent or flashing lock indicator,cycles that stop mid-program when the lid should be locked,or intermittent operation where the switch passes and fails continuity checks under manual actuation. Diagnostic steps include a visual inspection for broken plastic latch components or damaged wiring, a manual actuation while checking continuity across the switch contacts with a multimeter, and measuring the presence of the control signal to the lock during a commanded lock sequence (observe electrical safety precautions). Practical troubleshooting sequence: check the connector for corrosion or bent pins, confirm mechanical engagement of the striker with the latch, verify continuity when the latch is depressed, and verify the control board supplies the expected lock signal; substituting a known-good assembly or bench-testing the switch can isolate whether the issue is mechanical, electrical, or control-related.
- Washer won’t start or continues to show lid-locked status despite lid open
- Cycle pauses or stops during spin with lid lock indicator on
- Intermittent lock engagement demonstrated by inconsistent continuity when actuating the latch
- Visible damage to latch, broken actuator tab, or wiring/connector faults
| Item | Description |
|---|---|
| Continuity check | With latch depressed, switch contacts should show a conductive path; open when released. |
| Mechanical inspection | Verify striker alignment and absence of cracked plastic that prevents full engagement. |
| Control signal verification | During the lock command, confirm the control board applies the expected lock signal to the switch connector. |
Compatibility, Model Cross-Reference and Replacement Considerations with Installation Notes
The 137353300 Frigidaire Washer Lid Lock Switch is an electromechanical interlock used to detect lid position and, when required by the control logic, mechanically secure the lid during high-speed spin. The assembly typically combines a microswitch (signal) and a locking actuator; closing the lid completes the signal circuit to the control board and, upon a lock command, the actuator engages to hold the lid shut. Common failure modes are open or intermittent switch contacts, a seized or broken actuator, or damaged harness terminals; typical symptoms include the washer failing to advance from the fill or agitation phases, persistent lid-related error codes, or a clicking sound without the lid actually locking.
- Compatibility checklist: match OEM part number, connector pinout, mounting flange alignment, and actuator/stroke length.
- Electrical checks: verify continuity of the switch when actuated and confirm the control board provides the expected lock command voltage before assuming the switch is at fault.
- Mechanical checks: inspect the striker on the lid and the latch recess for wear or misalignment that can prevent reliable engagement.
- Safety/installation: always disconnect mains power before servicing; retain original fasteners and verify harness routing to avoid pinch points.
| Item | description |
|---|---|
| Function | Detects closed lid and provides a lockable interlock signal to the control board; also resists lid opening during spin. |
| Connector/Pinout | Must match the washer harness (verify number of pins and wire colors); mismatch can prevent signaling or power to the actuator. |
| Mounting | Check flange orientation, screw hole spacing and actuator clearance; physical mismatch can prevent proper engagement. |
| testing | Continuity between switch terminals when actuator is depressed; measure lock voltage at harness during a commanded lock cycle. |
Before installing a replacement, visually compare the replacement to the original for connector type and mechanical geometry; models that use a simple microswitch without a mechanical latch are not interchangeable with assemblies that provide a powered lock. During installation, confirm the actuator aligns with the lid striker and that the harness is routed clear of moving components.After fitting, run a diagnostic cycle or a short spin to confirm the lock engages and releases correctly; if the new switch does not receive a lock command voltage, pursue wiring or control board diagnostics rather than repeated switch replacement. If connector differences exist, use a correct replacement harness or properly crimped adapter rather than improvising permanent splices.
Q&A
what is the 137353300 Frigidaire washer lid lock switch and what does it do?
The 137353300 is a lid lock assembly used on some Frigidaire/frigidaire-branded top-load washers. It detects that the lid is closed and mechanically locks the lid during the high-speed spin or certain cycles for safety. The control board relies on the switch to allow the washer to run; if the lock/switch fails, the machine will often refuse to start or will display a lid/lock error.
What are common symptoms that the lid lock (137353300) is failing?
Typical symptoms include: the washer won’t start or won’t advance past the fill or spin step; the lid won’t lock (or won’t release) even when the cycle commands it; recurring lid lock or door error codes on the display; the washer stops mid-cycle; or you hear the lock motor try to engage but nothing happens. Intermittent operation is also common with a failing switch.
How can I test the 137353300 lid lock switch with a multimeter?
First unplug the washer. Access the lock harness and disconnect the connector from the control board or remove the assembly so you can probe the terminals.Using the continuity or ohms function, check the switch contacts: with the actuator in the “unlocked” position you should see the expected open/closed circuit change when you actuate the mechanism (consult your service sheet for exact terminal pairs). If the assembly contains a lock coil, measure coil resistance – it should be a finite low resistance (typically tens to a few hundred ohms), not infinite. if you get no continuity when the switch should be closed or an open coil, the lock is faulty and should be replaced.
can I replace the 137353300 lid lock switch myself? What are the basic steps?
Yes,a competent DIYer can usually replace it. Basic steps: unplug the washer; open or remove the top/control panel to access the lock; note and then disconnect the wiring harness; remove the mounting screws and take out the old lock; install the new assembly (transfer any actuator/brackets if required), reconnect the harness, and reassemble. Always follow your model’s service manual or step-by-step instructions for panel removal to avoid damage. After replacement, restore power and run a short cycle to verify correct operation.
Are ther any safety precautions I should take before replacing the lid lock?
Yes. Always disconnect power at the mains before working on the washer to avoid electric shock. If the washer is hardwired, switch off the breaker.Avoid touching live connectors. Be careful with sharp sheet-metal edges when removing panels. If the lock is stuck, do not force it – remove the assembly per the service instructions so you don’t damage the lid or control panel.
Will replacing the lid lock fix error codes or do I need to reset the washer afterward?
Replacing a faulty lid lock usually resolves lid/lock error codes. Many machines will clear the error after the part is replaced and the washer is powered up. If the code persists, run the washer’s diagnostic/self-test mode or perform a power cycle (unplug 30-60 seconds then plug back in). If errors remain, check wiring, connectors, and the control board for other faults.
How do I know if 137353300 is compatible with my Frigidaire washer model?
Check your washer’s model number (usually on a tag inside the lid or on the back) and cross-reference it with the part number in the manufacturer’s parts list or a reputable parts supplier. The same-looking lock assembly can vary by model year or region, so verify compatibility by model number rather than visual similarity alone. if in doubt, provide the washer model number to the parts supplier or technician.
Should I buy an OEM 137353300 or is an aftermarket replacement acceptable?
OEM (original equipment manufacturer) parts are identical to the factory part and generally provide the best fit and reliability. Many aftermarket parts are functional and less expensive, but quality can vary. If the washer is still under warranty, use the OEM part to avoid voiding coverage. For older machines, a reputable aftermarket unit can be a cost-effective choice; buy from a seller with good return/exchange policies and check reviews.
