Why Your Wolf Range Keeps Clicking After Ignition

Continuous click-click-click after a Wolf surface burner has already lit is one of the most common calls we get — and it almost always traces to one of two physical failures, not the control board.

The Wolf DF and GR spark module re-fires the igniter as long as it sees any of three things: a flame-sense signal mismatch, a wet module body, or a cracked spark electrode shorting to the burner cap. Continuous clicking after a successful light eliminates the flame-sense path — if flame sense were the issue, the burner would extinguish, not stay lit.

Most common cause: water intrusion in the module after a deep clean. Homeowners pull the burner caps and grates, hose them down, and water finds its way through the spark-electrode boot into the module housing underneath. The module reads a short between adjacent spark channels and keeps firing. Solution: pull the module, dry it thoroughly with a low-heat source for 24-48 hours, and reseat the boots with the correct silicone seal.

Second cause: hairline crack in the ceramic of the spark electrode itself. This usually shows up six months to a year after a heavy cleaning session where the electrode was twisted slightly out of position. Visual inspection with a flashlight under magnification finds it most of the time.

Replacement modules are stocked on the van for the common DF and GR widths. We bench-test the suspect module after drying, and if it doesn't pass three consecutive clean ignitions, it gets replaced. No guesswork, no "let's order one and see."
