Robertshaw Ignitor Hot Surface 41-412

The Robertshaw 41-412 is a hot surface ignitor for gas fired heating appliances.

A useful point of diagnostic discipline concerns what an ignitor failure looks like versus what it does not.

An ignitor that does not glow at all, with the control clearly attempting ignition, is either open circuit, not receiving voltage, or has a broken connection. Measuring resistance across it and voltage at its connector distinguishes these in moments.

An ignitor that glows normally but the burner does not light is not an ignitor problem. The gas valve has not opened, gas supply is absent or inadequate, or the burner is obstructed. Replacing the ignitor in this situation achieves nothing.

An ignitor that glows and the burner lights but the furnace then shuts down is a flame sensing problem, not an ignition problem. The burner is lit; the control simply is not receiving proof.

Each of these presents to the occupant identically as no heat, and separating them before ordering parts is what distinguishes an efficient diagnosis from a sequence of guesses.

Handle the element by its base only, and protect it from mechanical shock during installation.

Applications include residential and light commercial gas furnaces, boilers, and heating appliances.
