This microwave high-voltage diode kit converts AC to DC in the high-voltage circuit so the magnetron can heat. Replacing a failed diode often restores heating performance. What it does:

  • Rectifies high-voltage AC to DC for the magnetron
  • Completes the high-voltage circuit with the transformer and capacitor
  • Common failure symptoms include running but not heating, loud humming/buzzing, or blowing a fuse/tripping a breaker at start
  • Visual clues can include cracking, swelling, or burn marks on the diode
What's included:
  • One high-voltage diode
Install notes:
  • Disconnect power before servicing; microwaves can retain lethal voltage even when unplugged
  • Properly discharge the high-voltage capacitor before handling components; use insulated tools and approved procedures
  • Note diode orientation/polarity and mounting; install exactly as the original

Tomtom for Model Number FRS6R2FB3

The ice maker quit working and the water dispenser is dry (dispenser never worked very well). I have replaced the filters regularly, replaced the ice maker, Refrigerator water inlet valve assembly, Still there is no water in the tray and the dispenser is dry. I can see water in the lines from the back of the frig and it will leak good when I want it to. There has to be something stopping the water flow. Where is this Diode located? And would it cause these symptoms?

Answer

TomTom, The diode would normally not cause the unit to not make ice or dispense water but would cause water to come from the dispenser when ice is being called for. You will want to check the wiring at the back of the unit to make sure that it is not damaged in any way going to the valve. Also check the filter head to make sure that it is not damaged. This issue sounds more likely that it is either the fill tube for the ice and the dispenser are frozen or a wiring issue.
