Viking Delay-Off / Auto-Shutoff Failure Error Code Explained

Error Code Explained

What Does the Viking Delay-Off / Auto-Shutoff Failure Error Code Mean?

Viking Professional Series range hoods include a delay-off (keep-on) function that keeps the fan running at reduced speed for a set period after the main cooking cycle is complete, ensuring residual steam and odors are fully exhausted. When this feature fails — either the fan stays on indefinitely or the delay-off does not engage — the fault is in the control PCB logic that manages the timer function.

Root Causes

Common Causes of the Viking Delay-Off / Auto-Shutoff Failure Error Code

1

Control Board Timer Circuit Failure

The PCB-based timer that controls the delay-off interval can fail, causing either no delay (fan shuts off immediately) or infinite delay (fan runs continuously).
2

Firmware / PCB Programming Error

A power surge or data corruption event can cause the PCB to lose its programmed timing parameters.

Step-by-Step Guide

How to Troubleshoot the Delay-Off / Auto-Shutoff Failure Error Code

⚠️

Safety First: Always disconnect the Vent Hood from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.

1

Power Cycle the Hood

Switch off the circuit breaker for 60 seconds and restore power. A PCB reset may restore the delay-off timing function.

FAQ

Frequently Asked Questions — Viking Delay-Off / Auto-Shutoff Failure

The delay-off feature keeps the fan running at low speed for 5-15 minutes after you turn the hood off. This ensures lingering cooking vapors, steam, and odors are fully exhausted from the kitchen — a useful feature after high-heat cooking sessions.
Yes. A fan that runs continuously without shutting off is typically caused by the delay-off timer circuit being stuck in the active state on the control PCB. A power cycle may clear it; if not, the board requires professional service.
