Door or hood is difficult to close or does not seal properly.

Safety first: Turn off power to avoid accidental operation while working on the door or hood.

Step-by-step checks:

• Inspect hinges and guides: Look for bent or loose hinges. Tighten mounting hardware and straighten minor bends if possible.
• Examine gasket: Check the door/hood gasket for tears, flattening, or hardening. Replace if it no longer provides a uniform seal.
• Clean sealing surfaces: Remove scale and debris from the tank rim and door surfaces with a non-abrasive pad.
• Adjust latch: If the latch is adjustable, set it so the door closes firmly without excessive force.

When to call a technician: Significant frame or hinge damage should be evaluated and repaired by a professional.
