    Signs. Likely Causes. Solution.

    Signs: Display is on, but microwave won’t run when pressing Start.
    Likely Causes: Faulty door switch, bad control board, or blown thermal fuse.
    Solution: Check door switches for continuity (microwaves usually have 3). If all good, test fuse and control board.

    Signs: Oven powers on but doesn’t reach set temperature.
    Likely Causes: Bad bake or broil element, faulty temperature sensor, or defective control board.
    Solution: Test elements for continuity. Check sensor resistance (typically ~1100 ohms at room temp).

    Signs: Turntable spins, light is on, but food stays cold.
    Likely Causes: Defective magnetron, high-voltage diode, or capacitor.
    Solution: Carefully discharge high-voltage capacitor, then test and replace faulty components.

    Signs: Buttons don’t respond or respond incorrectly.
    Likely Causes: Failed membrane keypad, touch controller, or main control board.
    Solution: Test keypad ribbon and control signals. Replace the faulty part (often the touchpad or board).

    Signs: Interior light won’t toggle with door or during use.
    Likely Causes: Defective door switch, relay on board, or bad light socket.
    Solution: Test door switches and output from control board to light circuit.
