veteran techs know that carbon buildup or a failing thermocouple within the assembly is often the culprit

making it a reliable choice for protecting heat exchangers and steam generators from over-firing or thermal expansion

ensuring perfect bolt-hole alignment and gasket sealing

ensure you verify the amperage draw and insulator integrity of the existing electric heat kit frame

Technicians should perform a resistance (ohm) check across the leads or use an amp probe during the off-cycle to ensure the 100-watt element is drawing current
