Why Your Wolf Range Keeps Clicking After Ignition

Continuous spark after a burner has lit is usually a wet spark module or a cracked spark electrode — both are common after a deep-clean.

The shop floor is where every theory gets tested. We see the same failures on these four brands over and over — and a tight feedback loop between bench, manufacturer documentation, and authorized parts distribution is what keeps the diagnostic honest.

This article walks through what we've actually seen on recent calls: the symptom, the diagnosis path, the part we replaced, and the test we ran on the way out. None of it is hypothetical. All of it came off a service ticket in the last twelve months.

What the symptom usually means

Symptoms are deceptive on built-in appliances. A complaint of "not cooling" rarely points to the compressor — more often it's a board, a fan, a damper, or an air-path obstruction. Our diagnostic procedure isolates the system before we touch any sealed-system component.

How we diagnose without throwing parts

We pull current readings, refrigerant pressures (warm-side and cold-side), and air-temperature deltas before we form a hypothesis. The parts catalog is what fails last — not what we open first.

What we typically replace

Across recent visits, the most common parts were defrost thermostats, evaporator fan motors, control boards (specific revisions), and door gaskets. We order every one of them OEM, direct from the manufacturer's authorized distribution.
