Description
Product Summary
The McDonnell & Miller EA-157-L is an igniter / flame sensor from McDonnell & Miller, described by the manufacturer as: long electrode for 157-RBP 354107.
Igniters, flame sensors, pilots and thermocouples handle the lighting and flame-proving side of a gas or oil burner. The igniter or pilot lights the gas, and the flame sensor, thermocouple or thermopile tells the control that flame is present. A cracked or weak igniter, a sooty pilot, or a flame sensor with a low microamp reading are common reasons a burner lights and then shuts off or never lights at all.
