What You'll Learn
Replacing the diode
Before attempting any microwave repair, it is important to discharge the transformer's capacitor. Once this is done, you can open the diagram/schematic found inside the microwave oven and follow the technician's troubleshooting steps.
The diode is an electrical current control device inside the microwave. It provides high voltage that powers the magnetron. You may need to replace it to fix the issue. The diode's part number is PS953843.
To replace the diode, you will need to remove the cover of the microwave. On the back of the appliance, there will be screws holding the cover in place. Once the cover is removed, you will be able to access the diode and replace it with a new one.
It is recommended to check the diode before replacing it, as sometimes the issue may lie elsewhere. In some cases, replacing the diode may not solve the problem, and other parts such as the magnetron or thermostat magnetron may need to be replaced as well.

Replacing the magnetron
To replace the magnetron of a General Electric Microwave JE2160SF03, follow these steps:
Firstly, before replacing the magnetron, it is recommended to check the high-voltage diode, part number PS953843. This is an electrical current control device inside the microwave that provides the high voltage to power the magnetron. You may need to replace it to fix the issue.
Once you have checked the diode, you can proceed to replace the magnetron. Take the built-in microwave out of the cabinet and place it on a flat surface, such as the kitchen floor. You will need to remove the Safety Torx nuts on the reverse of the unit using the right wrench.
Next, discharge the transformer's capacitor before attempting any repairs. This is an important safety step. Refer to the diagram or schematic found inside the microwave oven for guidance if needed.
Once the capacitor has been discharged, follow the technician's troubleshooting steps to check the capacitor, diode, and transformer. If these components are functioning properly, you can proceed to replace the magnetron.
Order the magnetron part and, once received, go to the location of the magnetron inside the microwave. Attach the new sensor to the new magnetron and remove the old one. Connect the harness from the transformer to the new magnetron.
Finally, test the microwave oven to ensure it is working properly.

Testing the capacitor
A microwave that is not heating properly can be caused by a malfunctioning high-voltage circuit component, such as the capacitor. If the capacitor is unable to hold a charge or the charge is too weak, the microwave may still turn on, but no high voltage will reach the magnetron, which will be unable to send out electromagnetic waves to heat up the food.
Before testing the capacitor, it is important to discharge it, even if you suspect that it cannot hold an electrical charge. To do this, place a screwdriver blade or needle-nose pliers across each set of capacitor terminals. The handle of the screwdriver or pliers should be insulated, and you should avoid touching the metal portion of the tool when it is in contact with the terminals.
There are two tests you can perform to determine if the capacitor is functioning normally. The first uses an analog-style ohm meter to test if the capacitor is capable of storing and then releasing its electrical charge. The second test will determine if the component is operating with the proper capacitance rating and requires a capacitor tester or a multimeter with a capacitor-testing function.
- Disconnect the wires from the capacitor terminals and isolate or uninstall the capacitor from the microwave.
- Calibrate the analog-style ohm meter by contacting the ends of the meter leads together while adjusting the needle to read "zero". Then, rotate the meter’s range selection dial to a setting of 1,000 ohms or higher.
- Contact one meter lead to one of the capacitor terminals and the second lead to the other terminal.
- Observe the meter display.

Checking the transformer
Before attempting any repairs on your General Electric Microwave JE2160SF03, it is very important to discharge the transformer's capacitor. You can do this by opening the diagram/schematic found inside the microwave oven and following the technician's troubleshooting steps.
Once you have discharged the capacitor, you can begin checking the transformer. The transformer supplies power to the magnetron, so it is important to ensure that it is functioning properly.
To check the transformer, you will need to locate it inside the microwave. It is usually located near the magnetron and is connected to it via a harness. Once you have located the transformer, you can visually inspect it for any signs of damage or wear. Check for any burnt or damaged components, as well as any loose connections.
If the transformer appears to be in good condition physically, you can then use a multimeter to test its electrical continuity. This will help you determine if the transformer is functioning properly. Touch the multimeter probes to the transformer's terminals, and check the reading. A standard transformer should read somewhere in the range of 200-400 ohms. If your transformer reads outside of this range, it may be defective and need to be replaced.
It is important to note that working on microwave repairs without proper knowledge or training can be dangerous, as microwaves contain high-voltage components that can cause serious injury or death if mishandled. If you are uncomfortable or unsure about any part of the process, it is always best to consult a professional repair technician.

Connecting wires
To repair a General Electric Microwave model JE2160SF03, you may need to connect wires properly. Here is a step-by-step guide on how to do this:
Before attempting any repairs on your microwave, it is very important to discharge the transformer's capacitor. Open the diagram or schematic found inside the microwave oven and follow the technician's troubleshooting steps. Check the capacitor, diode for a short, and the transformer's windings that supply power to the magnetron.
If you have identified that the issue is due to loose or disconnected wires, follow these steps:
- Ensure the power source to the microwave is disconnected for safety.
- Locate the loose wire. You may need to refer to the schematic or a technician for this.
- Using a screwdriver, carefully tighten the connection of the loose wire to its corresponding component.
- Secure the wire in place to prevent further issues.
- Reconnect the power source and test the microwave to ensure it is functioning properly.
It is important to note that working on electrical appliances can be dangerous. If you are unsure about any part of the process, it is recommended to consult a professional repairman or electrician for assistance.
