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

Charli for Model Number fpus2698lf0

The water dispenser stopped dispensing water, and no water is getting to the icemaker. I replaced the Valve-water, triple solenoid and was able to get water to come to the tube under the freezer door when I disconnected it, but water will NOT come up into the door to the water dispenser NOT into the ice maker. I will add ice to the ice bin from a countertop ice maker, and the door controls for dispensing ice works, however, I can only use cubed not crushed. So, I'm not sure if it is the dispenser control board, or what I should do next.

Answer

Hello Charli, Since the water dispense and the icemaker fill are two completely separate circuits, these are separate issues. Since water will come out of the water line at the bottom of the door but not at the water dispenser, the water line in the door has to be frozen. You should be able to heat the door from the outside with a hair dryer to get the water line thawed out. You should check the fill tube for the icemaker to make sure it is not frozen. Many times, the ice that forms in the fill tube is clear so you will have to use a straw to see if it is frozen. If so, use a hair dryer on medium setting for about 15 minutes to thaw it out. If the ice crusher assembly will not switch back and forth, it is probably stuck due to small ice chips in the bottom of the crusher assembly. This can be corrected by putting your ice cubes in a bowl and washing out the crusher with hot water. Be sure to let it dry completely before putting the ice back in and putting the crusher back into the freezer compartment. If all of these problems occurred at the same time it is possible that someone may have set the units' operating temperature too cold, causing the drop in temperature to be too low, freezing the water tubing and the crusher assembly. As a note, the fresh food side should not be set too warm since this can cause the air circulation to be insufficient to stir and mix the temperatures and it will possibly cause the water tank and crisper drawers to freeze.
