Viking Range Error Code Latch LED

The Latch LED error indicates that the oven door latch system has failed to complete its expected movement. On a Viking range, this error is displayed as the Clean light flashing in a 1-second ON / 1-second OFF pattern while the Cycle light stays off. The latch must fully engage or release for the control board to allow a self-clean cycle to proceed. The oven halts operation to prevent unsafe conditions related to an unlocked door at high temperatures.

The latch error is specifically tied to the self-clean cycle function, which requires the door to be locked at very high temperatures. You should not attempt to run a self-clean cycle while this error is active. Normal baking and broiling functions may still operate, but the underlying latch problem should be repaired before using the self-clean feature again.

Disconnecting power to the range for several minutes may clear the error temporarily if it was caused by a transient electronic glitch. However, if the latch motor, limit switches, or wiring have an actual failure, the error will return as soon as the control board attempts to cycle the latch again. A power reset is a reasonable first step, but a persistent Latch LED error requires physical inspection and component testing to resolve.

Some causes of this error, such as a physical obstruction or loose wiring connector, can be addressed without replacing parts. However, diagnosing a failed latch motor or faulty limit switch requires basic electrical testing skills and comfort working around oven components. If you are not experienced with appliance repair, it is advisable to have a qualified technician complete the diagnosis and any component replacement.

Repair costs depend on which component has failed. A latch motor replacement typically falls in the range of $150 to $350 including parts and labor, while a control board replacement can run from $300 to $600 or more. A simple wiring repair or obstruction clearance will cost considerably less. Getting a diagnostic service call is the best way to identify the exact failure and obtain an accurate estimate.
