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

Questions & Answers

For Frigidaire High-Voltage Diode Kit (Microwave) (Part Number: OEM9662217)

1 Answer

Amanda, Yes, the harness diode has failed and will not allow the voltage to activate both fill valve solenoids. Repalce them and you should be fine. The part is in stock and available at this time. Thanks,

Garrett Otten for Model Number FRS3R5ESB3

Hello, I have a similar problem as all these other people. I live in Canada, so not sure if the models are different. I have a problem with dispensing water, When I press the water dispense paddle, it fills/overflows the icemaker and vice versa for when I press the ice paddle, it dispenses water from the water dispenser. I believe I need the Diode Kit but I am not sure if my model supports it for what the part number would be. Thanks, Garrett

1 Answer

Garrett, The diode kit should work for your model with the issue of the water dispensing from the dispenser when the icemaker fills or vice versa. Diode kit part number 5303918287.

Ryan for Model Number FRS6R5ESBL

When I use the water dispenser on my fridge, the water line that runs up the back of the fridge to the ice maker is also dispensing water at an equal rate. I have recently put a new water valve on initially believing that to be the problem but based on some of the responses I have seen on your site I believe it to be a bad diode after the valve didn't fix the issue. Would part number AP3220736 that you sell on your site work for my model? Would that be what you would recommend at this point?

Janet, This unit would not have a diode on it but you will want to check the fill tube in the back of the freezer to make sure that it is not frozen. If it is frozen the clear the ice out and this should resolve the issue.

Byron, This issue will be caused by a faulty diode kit and would recommend replacing both. There should be instructions that come with the kit.

Music1975, Unfortunately we do not have a instructions sheet on this diode kit but it should come with the kit. This kit 5303918287 will work for your unit.

Hello Evans. Sorry, there is no video. This kit may be used for replacement of diodes in ice and water side by sides with a water filter. The diodes are part of the main harness. There is a black insulator that protects the diodes. The diodes are located on the wire that goes to the inlet valve (#1 single coil valve), Approximately 4" away from the valve. Testing Shorted diode: When you activate the dispenser and water comes out both the dispenser and ice maker fill tube, the harness needs replaced. Open Diode: If the icemaker diode fails open, the single water valve will not energize when the icemaker is activated. If the dispenser diode fails open, the single valve will not energize when the dispenser is activated. Equipment needed: Voltmeter. 1. Activate dispenser, then check to see if there is voltage to the dispenser valve (Yellow Coil of dual valve should have close to line voltage) and check the inlet valve (single valve #1 can be tan or green, should have 54 to 78 VAC) If no voltage to both the inlet valve (Single valve) and the dispenser valve (Yellow Coil) then : A. Check the freezer door wiring connector. B. Check the dispenser connections. If there is voltage to the dispenser valve (Yellow Coil) and not to the inlet valve (Single Valve) replace the diode harness. 2. Activate Ice maker (Check during icemaker fill, which is about 7.5 seconds), then check to see if there is voltage to Icemaker valve (Green Coil of dual valve should have 95 to 105 vac) and check the inlet valve (Single valve #1 can be tan or green should have 42 to 58 VAC) If voltage to the icemaker valve (Green Coil) and not to inlet valve (Single Valve) Replace the diode harness. Replacement of Diode on Refrigerators with single coil valve by condenser fan and two valve by compressor 1. Disconnect power cord 2. Remove connector from single coil valve and remove the dark blue and yellow wires from the Molex connector. 3. Cut the two dark blue wires about 1" from the diode. (The diodes are inside the black heat shrink that the blue wire with yellow tracer goes into one end and the 2 blue and 2 yellow wires come out the other end) 4. Cut the yellow wire about 1" from diodes 5. Remove old diode subassembly. 6. The 2 blue wires cut in step 3 need to attaché to the brown wire in the new diode harness with the connector provided. Slide the heat shrink over the wire first, install the connector and slide the heat shrink over connector and heat to seal the connector. 7. The 2 yellow wires cut in step 3 need to be attached to the yellow wire in the new diode harness with the connector provided. Slide the heat shrink over the wire first, install the connector and slide the heat shrink over connector and heat to seal the connector.

Hello Alex, I'm sorry but the manufacturer has not provided a voltage across the diode. The diode is installed to prevent a signal being sent to the icemaker valve when the dispense valve has been energized.

Chris, You will want to test the diode on the wire harness going to the icemaker water valve. Also check the wiring under the unit to see if there are any damaged wires. If this does not correct then it would be an internal cabinet harness issue.
