• Replaces an element that is open, shorted, or intermittently heating
• Common symptoms: burner won't heat, heats unevenly, or only part of the zone glows
• Helpful when there is visible damage or hot spots on the element

• Disconnect power at the breaker; allow the cooktop to cool completely
• Access the element by lifting/removing the cooktop or from below
• Move wires one at a time to matching terminals; reuse any mounting clips/brackets as required
• Support the glass top during service and avoid stressing or scratching the surface

• Reassemble and test the burner from low to high to confirm proper cycling

This switch bracket mounting seal replaces a worn or damaged seal that cushions and protects the door or control switch mounting area. It helps keep the switch assembly seated and reduces debris and moisture intrusion for reliable operation. What it does:

• Seals the switch bracket mounting area to protect the switch from lint, dust and moisture
• Helps keep the switch properly positioned for accurate door or control sensing
• Can prevent intermittent or failed switch contacts caused by contamination or misalignment
• Useful when replacing a brittle, torn or missing mounting seal during switch or door repairs

• Disconnect power to the appliance before starting any repair
• Remove the door or panel per service instructions to access the switch bracket area
• Fit the seal into the bracket groove or around the switch housing, ensuring full seating without stretching
• Inspect adjacent clips or screws and reuse or replace as needed; test the switch function after reassembly
