# Wolf control board replacement

### Two boards and a conversation between them

Modern equipment from this maker has a relay board doing the switching, a control head doing the display, and a network carrying messages between them. Almost everything people describe as “the board has gone” is one of those three, and the appliance already knows which. Reading that before ordering is the difference between one visit and three.

### What actually goes wrong

- **Damp or condensation.** Not a failure at all, and it clears.
- **Supply problems.** Published in detail here, and often the house rather than the appliance.
- **The relay board.** The one that carries the heavy switching and wears from doing it.
- **The control head or the network.** Distinguished by the code, which is why the code matters.

### What decides the figure

Which board, and what has to come apart to reach it. The “from” is a single board on an accessible appliance, configured and tested before we leave.

What this involves

The code names the board before anything is ordered

Damp and supply ruled out first — both look identical

Configuration restored so it is your appliance afterwards

Rule out damp

Moisture on a board reads exactly like a dead board and clears on its own more often than people expect. Off at the breaker for half an hour, then tested again.

Rule out the supply

Over-voltage, under-voltage, a broken neutral in the house wiring — this maker publishes conditions for all of them, and none of them are the appliance to fix.

Read which board

Relay board, control head, or the network between them. The published conditions distinguish all three, and ordering the wrong one is a fortnight lost.

Set it up as yours

A new board arrives generic. Configuration, calibration and your settings are part of the job, not something you discover missing at dinner time.
