The Whirlpool WPW10687786 Diode directs electrical current within a compatible microwave’s high-voltage circuit to support proper heating. This electronic component allows current to flow primarily in one direction and works with the capacitor and other circuit components to supply the voltage required by the magnetron. A faulty diode may cause the microwave to run without heating foo... https://www.partsmelange.ca/whirlpool-wpw10687786-diode-for-microwave
