Safety first: Allow the oven to cool completely before touching the door seal.

Inspect the gasket: Check the entire perimeter seal for splits, hardening, or missing sections. Replace if any damage is found.
Check gasket retention: Ensure the gasket is properly seated in its channel or on its hooks. Refit any loose sections.
Clean door and frame: Remove built‑up grease from the door edge and front frame with a non‑abrasive cleaner so the gasket can seat properly.
Replace gasket: Fit a new Salter door gasket, starting at the corners and ensuring even tension. Test door closure and adjust if necessary.

Warning: Do not use adhesive unless specified by Salter; most gaskets are designed to clip in mechanically.

Oven door does not seal; visible gaps around the edges and heat felt escaping.
