Electrical Element Replacement   SB 176.1

Service Bulletin: SB 176.1

Subject: Electrical Element Replacement


Prior to removal of the defective element, measure the reference dimension shown in Figure 1. Check this dimension after the new element has been installed to verify that the element is fully seated (tight at both contact points) in the liner (see Figure 2).

The element should not move side-to-side when properly installed. Check for movement by holding the element pins and attempting to move the element body. If there is movement, remove and reseal it. Any gap between the heater element and the liner will cause the element to fail.
