Symptom
Wolf microwave controls behaving erratically
A keypad that misses presses, a display that scrambles, or a machine that starts something nobody asked for. Built into a stack with an oven, the first suspect is the supply they share.

Four ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The shared supply
Built-in microwaves are often on the same circuit as the oven under them. One supply problem, two strange appliances.
-
Heat from the appliance below
A microwave sitting over a working oven in a poorly ventilated housing gets warmer than it was designed for.
Appliance installation from $225 -
The touch panel
Grease and steam on a keypad directly above a cooktop, or a membrane that has worn.
Control board replacement from $365 -
The control board
Once the supply and the panel are ruled out. Named separately from the display side.

Feel the cabinet
A housing that is hot to the hand after normal cooking is an installation problem worth solving.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.
If there is no code at all
The data plate is inside the cabinet, upper left wall or behind the grille. All models

About Wolf microwave controls behaving erratically
The fastest diagnosis is the code
Check whether the oven in the same cabinet is also behaving oddly. Two appliances misbehaving together is a supply problem, not two coincidental failures, and it saves a wasted visit.
Look at the neighbor first
A built-in microwave rarely lives alone. It sits above an oven, often on the same circuit and inside the same housing, and both of those connections produce symptoms that look like a failed microwave. Checking the appliance underneath takes ten seconds and it changes the diagnosis completely.

Before you book
Questions about wolf microwave controls behaving erratically
The oven is odd too. Two failures at once?
Almost certainly not. Two appliances on one circuit behaving strangely together points at the supply, and that is an electrician rather than us — we will say so rather than sell you two boards.
It only misbehaves when the oven has been on.
Then heat is the answer, and the fix is ventilation rather than electronics. A built-in stack without proper clearance cooks the appliance at the top of it.
Is a worn keypad repairable?
The membrane is a part, and on this equipment it is worth doing rather than replacing a built-in appliance that has to fit an existing opening.
