Wolf RELAY FAULT Error Code — Warming Drawer Fault Fix

Error Code Explained

What Does the Wolf RELAY FAULT Error Code Mean?

A Wolf warming drawer heating relay fault means the electronic relay controlling power to the heating element has failed. If the relay sticks in the closed position, the element runs continuously and the drawer overheats. If the relay fails open, the element receives no power and the drawer does not heat. Both conditions require professional relay replacement.

Root Causes

Common Causes of the Wolf RELAY FAULT Error Code

1

Relay Contact Welding — Stuck Closed

The relay contacts have welded together due to arcing during switching, causing the relay to remain permanently closed.
2

Relay Coil Failure — Stuck Open

The relay coil has failed open, preventing the contacts from closing and cutting power to the heating element.
3

Age-Related Relay Contact Degradation

Repeated switching over many years has degraded the relay contacts to the point of failure.
