What 0630 Means
The auxiliary double line break is a further disconnect relay on the M Series relay board covering the secondary loads rather than the main bake and broil banks. Wolf's M Series Troubleshooting Manual records 0630 when that relay is sensed as closed while the control has it commanded open. Note the priority 3 rating - lower than the main bank DLB problems, but still a disconnect that is not disconnecting.
Common Causes of 0630
- Auxiliary DLB relay contacts welded closed
- A relay board sensing problem on the auxiliary channel
- A short on one of the auxiliary loads holding the sensed circuit made
🔧 One Safe Check You Can Try
Power down at the breaker and note anything on the oven that has been behaving oddly - a light that stays on, a fan that keeps running - since the auxiliary bank covers those secondary loads.
⚠ Why You Shouldn't Go Further Than That
- Even at priority 3 this is a relay that will not open, so the order is power off at the breaker, then diagnosis.
- The auxiliary bank shares the relay board with the heating circuits, which puts it firmly in line-voltage territory.
- Swapping a load - a light, a fan - because it will not switch off misses a relay upstream that is holding it on.
