Viking Range Error Code Latch LED (Clean light flashing 1s ON/1s OFF, Cycle light OFF)

This error code indicates that the oven control board has detected a problem with the door latch system used during self-cleaning cycles. The Clean light flashing in a 1-second on, 1-second off pattern is the board's way of signaling that the latch motor or door lock switch is not responding as expected. The oven will not proceed with a self-clean cycle while this fault is active. The Cycle light remaining off confirms the clean cycle has not started or has been interrupted before engaging.

Normal bake and broil functions typically do not require the door latch to engage, so regular cooking may still be possible. However, you should not attempt to run a self-clean cycle while the latch error is present, as the oven may not be able to properly secure the door at the extreme temperatures used during cleaning. Resolve the latch fault before using the self-clean feature.

Repair costs depend on which component has failed. A door latch motor or latch assembly replacement typically ranges from $80 to $200 for the part alone, while a door lock switch is generally less expensive at $20 to $60. Control board replacement, if needed, is the most costly option and can range from $200 to $500 or more for the part. Adding professional labor will increase total costs, commonly ranging from $150 to $400 for the full repair depending on the failed component and service rates in your area.

Some causes are DIY-friendly, such as clearing obstructions from the door frame, realigning the door, or reseating loose wiring connectors. However, replacing the latch motor assembly or door lock switch requires disassembling part of the oven door or rear panel and working near high-voltage components, so comfort with appliance repair is important. If you are not experienced with appliance electrical systems, a qualified technician is the safer choice. Always disconnect power to the range before inspecting or replacing any components.

A power reset by turning off the circuit breaker for 60 seconds and restoring power may temporarily clear the error if it was caused by a one-time control board communication glitch. However, if the underlying latch motor, switch, or wiring fault is still present, the error will return as soon as the oven attempts to engage the latch again. A persistent latch error requires physical inspection and likely component replacement to resolve permanently.
