Microwave not heating food? A faulty high voltage diode disrupts power conversion. Common DIY repair requiring discharge safety and multimeter testing.
After dismounting the unit from its wall-hanging bracket, the most tedious part of the repair was removing over a dozen screws holding the cover in place from the top, bottom, and both sides. Fortunately, I had placed the unit on a bench that allowed me to slide the unit allowing access to the screws on the bottom edges of the unit. Always discharge the capacitor before continuing to work on the unit by discharging the capacitor by shorting the contact without the diode to ground. Access to the... Read more

Checked the three door switches; used ohm meter to see if there was resistance or if a switch was bad. 2 out of 3 switches showed resistance with the ohm meter. The last one tested (of course the last one) NO (normally open) did not show resistance; I.e. the ohm meter reading did not change when the switch was depressed. Appliance parts pros was the only company that had the same model number I was looking for (SZW-V16-FD-63). I ordered the relay switch, 2 days later it arrived (regular... Read more
Fix a microwave that runs but won't heat or won't start when door closes. This door switch is a common fix—most DIYers replace it in 15 minutes.
Fix a microwave that runs but won't heat with this high voltage diode. Converts AC to DC power for proper heating. Typical DIY repair in under 2 hours.
I am not an appliance repair man. I am a general surgeon. I went online and researched the problem. The consensus was that my magnetron and diode were the most likely culprits. To replace my microwave with a comparable model would have cost at least $800. The diode and magnetron cost around $170. I watched a few videos on YouTube demonstrating how to do the repair safely and I felt like I could do it. I ordered the parts on a Monday evening and had them Wednesday. The only difficult part of... Read more
Microwave won't turn on or has no power? A blown fuse is often the cause. This safety component protects against electrical surges and short circuits.
I have a Jenn-Air microwave that didn't turn on and had no lights. It just stopped working completely. I unplugged the unit and had to remove the rear cover using a *security screw kit* that prevents people from opening the rear panel. Once opened, I removed the fuse and testing it with an OHM reader to determine that the fuse went bad. But I also had to determine why the fuse blew and noticed a sticky oily substance under the Capacitor. I used a rubber glove and needle nose pliers to... Read more
Restores interior lighting in your microwave oven. Replace when bulb burns out to regain visibility while cooking. Verify fit using your model number.
Ordered and recieved new bulb, called help desk to find how to access the bulb. Found I needed a tamper proof torx bit to remove cabinet screws. After buying bit the job was a snap! Thanks to Appliance Pro. comm and their 24 hr. help line Read more
Supports and guides the turntable for smooth rotation in your microwave. Replace if wheels are worn, cracked, or causing grinding noises. Confirm fit with your model number.
Just installed the items purchased from you. Read more
Glass turntable tray for countertop microwaves. Replace your cracked, broken, or missing rotating tray. Provides stable surface for even heating.
Replaced it. Perfect fit. Thanks Read more
Microwave has no power or won't turn on? This fuse cartridge protects against electrical overload. Requires removing outer cover to access and replace.
Removed microwave from the built in cabinet (probably the hardest part) and took off top cover (screws on side and back). Had previously blown the power fuse 2 times in this microwave, so I checked the fuse first using an ohmmeter. This time fuse was good. Traced the power wires around to top side of microwave and saw the overheat "therm" switch. I believe the therm is installed there as a safety feature to open the power circuit to the microwave in case something was to overheat for any... Read more
Self-tapping screw for refrigerators. Secures handles, panels, and internal components. Replace missing, stripped, or damaged screws during repairs.
After receiving the part, I found I had to dismantle the left side of the handle in order to fix the right side that was broken. When I took the left side of the handle off I found the plastic piece that broke on the right side was about to break on the left side also. Having all the details and in advance of another broken handle, I ordered the part, just to have when it breaks. Read more
Microwave stopped heating or makes humming noise before shutting off? The high voltage capacitor often fails first. DIY repair in under 30 minutes.
Main Fuse did not open, only fuse for high voltage section was opened. Prior to the fuse blowing a louder than normal hum was heard from microwave for 1-2 seconds prior. Easy fix is the high voltage capacitor, so first checked the voltage across the capacitor terminals to ensure capacitor was discharged. Typically should be reasonably discharged within 30sec-1min assuming drain resistor is still in place. Removed the high voltage cap, and checked the capacitance and did not get a reading....

Replaces the interior ceiling cover panel in your microwave. Needed when the original cover is cracked, ripped, torn, or missing. Restores protection.
Replaced the cover,all is good. Received my new part very fast. Great service Read more
The magnetron is the component that generates microwave energy used to heat food. It converts high-voltage electrical energy into electromagnetic waves directed into the cooking cavity. Replace the magnetron if the microwave runs but does not heat food, makes unusual buzzing sounds, or trips the circuit breaker during operation.

This is an oil-filled high-voltage capacitor used in the microwave's magnetron circuit. It stores and releases electrical energy to help power the magnetron, which generates the microwaves that heat food. Replace this capacitor if the microwave runs but does not heat, hums loudly without heating, or if the capacitor has visibly bulged or leaked oil.
Downloaded service manual, got over my fear of getting shocked. Found Samsung put bleed resistors in capacitor, jumped with screwdriver to confirm as per service manual. Tested diode, found a large voltage drop with 9v battery. Capacitor test failed. Called into APP to confirm, got some great advice. Ordered cap and diode, arrived next day, installed and corrected problem. This micro has conv and is built into my motorhome, I had few options, none really, but to fix and no one wanted to...
