Is This the Right Part?

Common Symptoms

• Range control or electronic circuit may be inoperative if the diode is open or shorted.
• Intermittent or incorrect control-board operation may occur when the diode no longer regulates voltage correctly.

Check Before Replacing

• With power disconnected, inspect the diode and circuit board for visible scorching, cracking, or physical damage.
• Test the diode with an appropriate diode or zener-diode test method; compare the result with the documented 5.6 V zener specification.
• Do not rely on continuity alone to confirm a zener diode is good.
