Thermador Cooktop Sparking Continuously
Cooktop Sparking Continuously is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Corrosion in permanently humid air
Bearings and mounts here degrade in damp rather than simply wearing, and noise arrives before the service interval expects it.
A failing fan motor
Evaporator or condenser fan bearings wear out gradually, producing noise well before the fan actually stops running.
Loose or vibrating panels
Cabinet panels or compressor mounts that have loosened over time can resonate against nearby surfaces.
