Is This the Right Part?

Common Symptoms

• No bake, broil, or convection heating
• Intermittent power or heating operation
• Oven may exceed the temperature setpoint or fail to turn off

Check Before Replacing

• Disconnect electrical power before inspection or testing.
• With power disconnected, inspect the board, harnesses, and connectors for loose connections, overheating, burn marks, or damaged terminals.
• Check the oven heating elements, temperature-sensor circuit, and wiring for obvious damage or an open circuit before condemning the relay board.
• Confirm that all board connectors are fully seated and correctly routed; symptoms alone do not prove board failure.
