Always verify there is no ground fault before installing the new unit

Enhanced Signal Integrity: Provides low-resistance electrical paths for critical components like flame sensors and ignition modules

This typically indicates a fouled seat or a failed thermostatic bellows

Frequent tripping usually indicates high current draw from a failing start capacitor

Most failures result from improper belt tension or misalignment

Viessmann 7816460 Cad Cell 323613-751 Always verify there is noThe Viessmann 7816460 Cad Cell is a critical flame sensor designed for precise oil burner monitoring in residential and commercial heating systems. As a high performance cadmium sulfide photocell, this component acts as a vital safety interface, sensing light in the visible spectrum to verify ignition and continuous combustion. When the burner fires, the Viessmann cad cell resistance should typically drop below 1,600 ohmsoften settling between 300 and
