High-Voltage Diode – Part Number: DE91-70063D
$28.26
In Stock
High-Voltage Diode
★★★★★

(4)
Part #DE91-70063D
This high-voltage diode is designed for use within various makes and models of microwaves and is a genuine OEM part that converts alternating current (AC) into direct current (DC). If you notice your microwave turns on and starts but does not heat anything, this diode is likely responsible. You can check the continuity of the diode with a multimeter before outright replacing it, but it is important to remember that doing any repairs on a microwave and dealing with sensitive electrical components should be done carefully and with the appropriate precautions to avoid any hazards. To replace the high-voltage diode in your microwave, disconnect it from power and allow it to discharge. Using the appropriate screwdrivers, gain access to the control panel of the microwave. Using an insulated screwdriver, release any electrical charge in the capacitor by touching it across the terminals. Then you can remove any hardware securing the diode, including the harness connecting it to the capacitor, which may be easiest done with pliers. Connect the new diode to the capacitor terminal and the securing bracket, and then reassemble your microwave before connecting it to power again.

Not the original type bulb

The repair was very easy, however the bulb was not the same as the original one. The original bulb had a bright setting and a low setting, but the replacement bulb was only the low setting bulb. There was no bright and dim operation. The switch on the microwave had the duel settings.

Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.

Appears to work, but food not heated

The high voltage tired was shorted. I replaced it with a new one, but that did not solve the problem.

You can test the high voltage tired with a voltmeter and a 9 V battery. Search Search for it on YouTube.

You can also test the high voltage capacitor, the high-voltage transformer, and the magnetron with a multi met er. Search for the procedures on YouTube.

I tested all these high-voltage components with a low-voltage multi meter, and they all checked out OK (after replacing the diode). However the microwave still did not heat food.

When working on a microwave it is important to unplug it and also discharge the high voltage capacitor. The capacitor has a 10 megaohm resister to automatically discharge itself, but it may have failed – – so discharge it manually.

In the end I ordered a new microwave.
