4.89 (64)
By: Frigidaire
Part Number: OEM9662217
Manufacturer Part Number: 5303918287

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

Ashley for Model Number Fridigaire 5303918287

I am not sure if I should ask this here, but my ice maker stopped working, so I ordered this diode wire harness and installed it Sunday. After install, the ice maker made about 5 ice cubes, and then just stopped. The manual arm on the ice maker was about halfway up, and it took a tad bit of force to get it back into the correct place. Since it has been set to "on", it has not made a single piece of ice since the first 5 after the diode install. What else could be the problem, and is there a part on here I can buy?

Answer

Hello Ashely. You need to check and see if there is power going to the water valve when the icemaker cycles. If so, replace the water valve on the unit. If not, or the icemaker does not cycle, you will need to replace the icemaker on the unit. Also, check and make sure the fill tube on the unit is not frozen and clogged. If so, replace the water valve and thaw out the fill tube. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
