(3)
Part #EBG61305805
This temperature sensor, also known as a thermistor, is compatible with various makes and types of appliances. This thermistor uses electrical currents to detect the interior temperature of the appliance it is in and by working with the control board, the board adjusts the level of cooling or heating through its heating or cooling element, depending on what is needed. If your appliance is being improperly heated or cooled, the temperature sensor may be to blame, and can be tested with a multimeter to check for continuity to see whether it is defective. Check your user manual for exact placement of this thermistor and any diagnostic information.

Magnetron
★★★★★
★★★★★
(8)
Part #6324W1A001L
This magnetron in your microwave creates the radiation needed for cooking or warming your food. It is located inside the main cavity, typically near the transformer or waveguide. When the magnetron becomes defective, your food may not heat up properly or heat up at all. Additionally, buzzing or humming sounds may be noticeable while the microwave is in operation. With a malfunctioning magnetron, your microwave loses its primary function. To remove it, you first need to unplug your microwave from its outlet. Before touching any components, discharge the capacitor by placing a screwdriver, with an insulated handle, across the two terminals of the capacitor. Once the capacitor is discharged, replace the current magnetron by disconnecting it from any wires and removing any mounting screws or clips. This magnetron is sold individually and is supplied directly from the original equipment manufacturer.

THERMOSTAT
Part #EBG51439303
This thermostat is a temperature-sensing device that controls and maintains the desired temperature inside the oven. It is an OEM replacement part that works by monitoring the internal oven temperature and signaling the heating elements to turn on or off as needed to maintain the set temperature. You can find the thermostat at the back of the oven, near the top or bottom. In some ovens, it may be located behind the control panel. Thermostat failure can occur due to wear and tear, electrical issues, or damage. If the thermostat fails, it can result in temperature inconsistencies, such as the oven not reaching the desired temperature or overheating. This can lead to uneven cooking, undercooking, or burning of food. Before beginning this repair, disconnect the oven from the power source to avoid electrical hazards Locate the thermostat and carefully disconnect the wires connected to it. It is advisable to take a picture or label the wires to ensure proper reconnection later. Gently pull out the thermostat from its housing and position the new thermostat in place. Reattach the wires to the corresponding terminals on the new thermostat. Reconnect the oven to the power source and test that the new thermostat is functioning by monitoring the temperature inside the oven.

Special Order
Capacitor
Part #0CZZW1H004B
Store the electrical energy needed by a microwaves high-voltage heating system with this replacement capacitor. During cooking, the capacitor works with the transformer, diode, and magnetron to help create the energy that heats food. A faulty capacitor may be linked to no heat, loud buzzing, or a fuse that blows when cooking begins. However, these signs can also come from other high-voltage components, so proper testing is important. Microwave capacitors may hold a deadly electrical charge even after the power cord is unplugged. For this reason, testing and installation must be completed by a qualified appliance service technician.

Magnitron failed
8 of 13 people found this instruction helpful.
  • Joseph from WILTON, NH
  • A Bit Difficult
  • 1- 2 hours
  • Screw drivers
Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover .
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

Would not heat and made a buzzing or popping sound

  • Thomas from NEWARK, DE

  • 15 - 30 mins

Unplug the microwave. Remove the Philips head and safety Torx head screws along the bottom of the sides and rear of the microwave which hold the black cover on. Lift the cover up at the rear and slide it backwards to disengage the tabs on the front top. Remove the cover. Discharge the capacitor by shorting the terminals to each other and then ground. Do this with a well insulated object and be aware there may be a pop when you do this. Keep hands, etc. on the insulated part of the object (screwdriver handle, etc). There's a lot of stored energy in that capacitor. I'd advise first checking the diode to make sure its not bad. Replace it if it is. The Magnatron is held in with a couple of screws on the top and sides. Unplug the connector and remove the screws. Remove the Magnatron. Installation is the reverse of removal.
