GE Microwave is Making Noise and Not Heating
There are three possible reasons your GE microwave is making noise and not heating. We are going to talk about each of them, and show you how to fix them.
The Diode
To test and replace the diode in a GE microwave do the following…
Step 1: Unplug the microwave.
Step 2: Take out the screws which hold the front grille of the microwave in place. There will be two or three screws.
Step 3: Open the door of the microwave and take out the front grille.
Step 4: Take out the screw right next to the control panel and loosen the other one behind it if there is on.
Step 5: Lift the control panel up to detach it from the microwave.
Step 6: Take out the screw which holds the inner access panel in place.
Step 7: Remove the panel.
Step 8: To avoid the risk of getting injured, you will need to discharge the capacitor. Do this by placing a screwdriver over the terminals of the capacitor simultaneously. Make sure not to touch the metal portion of the screwdriver when you do this.
Step 9: Unscrew the diode from the frame.
Step 10: Disconnect the diode from the capacitor.
Step 11: Using a multimeter, test the capacitor. If there is no continuity, you will need to buy a new diode. Click here to know how to test a diode using a multimeter.
Step 12: Get a new diode and connect it to the capacitor.
Step 13: Screw the diode to the frame.
Step 14: Return the inner access panel and hold it in place with the screw.
Step 15: Push the control panel back in and return the screw behind it and the other one right next to it.
Step 16: Return the microwave front grille and the screws at the top.
Step 17: Plug the microwave back in.

The Capacitor
If your GE microwave is making noise, it may be because of a faulty capacitor. To test and replace the capacitor in a GE microwave, follow these steps…
Step 1: Turn the microwave off and unplug it.
Step 2: If your microwave is installed to the cabinet, it will need to be uninstalled. First, take out the glass tray and support from the microwave.
Step 3: Remove the bolts which secure the microwave to the cabinet. Have an assistant support the microwave while you do this.
Step 4: Carefully tilt the microwave forward and pass the power cord through the hole in the cabinet.
Step 5: Lift the microwave up from the mounting plate and place on a sturdy surface lined with a cloth.
Step 6: Take out the screws at the top of the front grille.
Step 7: Open the microwave door and take out the front grille.
Step 8: Rest the microwave on its back.
Step 9: Take out all the screws which hold the bottom panel in place.
Step 10: Disconnect the wires and detach from the retainer.
Step 11: Set the bottom panel aside.
Step 12: Turn the microwave back up.
Step 13: Take out all the screws at the top, back, and sides of the microwave which hold its cover in place.
Step 14: Remove the microwave cover.
Step 15: Discharge the capacitor by placing a pair of pliers on the terminals simultaneously.
Step 16: Note where each wire is connected to on the capacitor then disconnect them.
Step 17: Take out the screws which hold the capacitor in place.
Step 18: Lift the capacitor and the mounting bracket out.
Step 19: Remove the bracket from the capacitor.
Step 20: Test the capacitor using a multimeter. If there is no continuity, get a new capacitor. Read this if you would like to know how to test a capacitor using a multimeter.
Step 21: Transfer the mounting bracket to the new capacitor.
Step 22: Screw the capacitor down.
Step 23: Return the microwave cover and secure with all the screws.
Step 24: Rest the microwave on its back.
Step 25: Reconnect the wire to the bottom panel and secure the wire in the retainer.
Step 26: Screw the bottom panel in place.
Step 27: Return the front grille and the screws at the top.
Step 28: Lift the microwave up and sit it on the mounting plate.
Step 29: Pass the power cord through the hole in the cabinet.
Step 30: Secure the microwave to the cabinet with the bolts.
Step 31: Return the glass tray and support.
Step 32: Plug the microwave back in.

Step 6: Take out the screws at the top of the front grille.
Step 7: Open the microwave door and remove the front grille.
Step 8: Turn the microwave to rest on its back.
Step 9: Take out all the screws which hold the bottom panel in place.
Step 10: Disconnect the wire connector and detach it from the retainer.
Step 11: Fully take out the bottom panel.
Step 12: Take out all the screws which hold the microwave cover in place. There will be some at the back, sides, and top of the microwave.
Step 13: Remove the microwave cover.
Step 14: Discharge the capacitor by placing a screwdriver over the terminals simultaneously. Make sure you do not touch the blade when you do this.
Step 15: Disconnect the wires connected to the magnetron.
Step 16: Take out the screws securing the magnetron to the frame.
Step 17: Remove the magnetron.
Step 18: Disconnect the wires connected to the thermoprotector on the magnetron.
Step 17: Unscrew the thermoprotector from the magnetron.
Step 18: Test the magnetron using a multimeter. If there is no continuity, the magnetron is faulty. Click here if you would like to know how to test a magnetron with a multimeter.
Step 19: Get a new magnetron and screw the thermoprotector to it.
Step 20: Align the magnetron on the frame and reconnect the wire to the thermoprotector.
