What E45 means on a Frigidaire washer

Error code E45 on a Frigidaire washer indicates a lid locked sensing failure. This means the control board is unable to confirm that the lid lock mechanism has engaged or disengaged properly. The lid lock system uses a locking actuator and a sensing switch that sends a feedback signal back to the main control board. When that feedback signal falls outside expected parameters, or is absent entirely, the control board cannot verify lid lock status and triggers E45.

The lid lock assembly is a safety-critical component. The washer will not run spin cycles without confirming the lid is secured. A sensing failure can stem from a faulty lid lock switch, a broken or disconnected wiring harness between the lid lock and the control board, or a defective control board that is misreading or not receiving the signal. Physical damage to the lid lock mechanism itself, such as a stripped actuator or a lid strike that is misaligned, can also prevent proper sensing.

The starting point for diagnosing E45 is Test 6, which is the designated lid lock diagnostic procedure for this platform. This test walks through verifying the electrical signal at the lid lock assembly, checking continuity and voltage in the circuit, and isolating whether the fault lies in the lock component itself or in the wiring and control board. Completing Test 6 before replacing parts is essential to avoid misdiagnosis.

Common causes of E45

  1. 01

    Faulty lid lock assembly

    Part replacement

    The lid lock actuator or its built-in sensing switch can fail mechanically or electrically, preventing the control board from receiving a valid confirmation signal. This is the most frequent cause of E45.

  2. 02

    Wiring harness issue

    Wiring / connection

    A loose connector, broken wire, or corroded terminal in the harness between the lid lock assembly and the control board can interrupt the sensing signal. Inspect the connectors at both ends for damage or poor seating.

  3. 03

    Misaligned lid strike

    Part replacement

    If the plastic lid strike that inserts into the lid lock is broken or shifted out of position, the lock actuator cannot engage fully, causing the sensor to never confirm a locked state.

  4. 04

    Defective main control board

    Part replacement

    If the control board is not correctly reading or supplying power to the lid lock circuit, it may falsely report a sensing failure even when the lock and wiring are functional. This is typically ruled out after other components test correctly.

Frequently asked questions about E45

What does E45 mean on a Frigidaire washer?
E45 on a Frigidaire washer means the control board has detected a lid locked sensing failure. The washer cannot confirm whether the lid lock has properly engaged or released. This is a safety-related fault that will prevent the washer from completing cycles that require a locked lid, such as spin. The diagnostic starting point is Test 6, which evaluates the lid lock circuit.
Can I fix E45 on my Frigidaire washer myself?
Some causes of E45, such as a loose wiring connector at the lid lock assembly, can be addressed without special tools. However, replacing the lid lock assembly or diagnosing the control board requires basic electrical knowledge and comfort working with appliance components. Running the Test 6 diagnostic procedure first will help narrow down whether the problem is the lock itself, the wiring, or the control board before purchasing parts.
Is it safe to use my Frigidaire washer when E45 appears?
It is not recommended to continue using the washer while E45 is active. The lid lock is a safety system designed to keep the lid secured during high-speed spin. If the washer cannot confirm the lid is locked, it may refuse to spin or, in some cases, operate unpredictably. Resolve the fault before resuming normal use.
How much does it cost to repair a Frigidaire washer E45 error?
If the fix is a wiring connector, there may be no parts cost at all. A replacement lid lock assembly typically costs between $20 and $60 for the part. If the main control board is at fault, the part alone can range from $80 to $200 or more. Adding professional labor will increase total repair costs by $75 to $150 depending on your area.
Will resetting my Frigidaire washer clear the E45 error code?
A power reset may temporarily clear E45, but the code will return if the underlying fault in the lid lock circuit is not repaired. Unplugging the washer for a few minutes and restarting it is a reasonable first step to rule out a one-time electronic glitch, but a recurring E45 indicates a real component or wiring problem that requires diagnosis using Test 6.
