Sm272yb Serial Parts

This Faraday cage is the metal cavity shield that surrounds a microwave's cooking chamber to contain microwave energy and protect internal electronics. Replacing a damaged cage helps stop arcing and restores safe, even cooking performance. What it does:

• Shields and contains microwave energy inside the oven cavity to prevent leakage
• Protects internal components and control electronics from stray RF and interference
• Prevents arcing and sparking caused by holes, dents, or damaged shielding
• Helps restore even heating when cavity damage is the root cause of performance issues

• Disconnect power at the breaker before beginning any repair.
• Handle with care—edges may be sharp; use gloves and eye protection.
• Verify alignment and door latch/ seal fit after installation to ensure proper microwave containment.
