check magnetron

Microwaves only have a couple of things that can be simple to fix, One is the high voltage diode and the other is the capacitor. If it is not one of those then you need to order parts which might not be available for something that old. You need to tell us if it is completely dead or you have display. Could be a fuse inside if you dont have a display. Otherwise they can be dangerous to work on.

There are different variants why it stopped working properly. I've experienced kinda similar situation, however I'n not that smart in techs to try to fix it. So, I just bought a new one. By the way, I've had only brand models for the couple of years, however I decided to try buying something more affordable, but still qualitative. I've been browsing in searchings for the best budget variant when I came across https://readyresearch.com/best-microwaves-under-100/ . This article consists of the list of best microwaves "under 100", the buyer's guide and even FAQ is provided for the common questions, so everything you need to know before making a decision is gathered in one useful article. I've bought Nostalgia RMO7RR Retro Microwave which matches all the characteristics it was given there. Just look at that red color! Perfect choice. I suggest you try to look through this page and pick sth with lower price. At least it wouldn't be as disappointing as if brand model breaks down, so just check it!

Sounds like you have burnt out the heat sensor.

The control panel will cost more than a new microwave

Sounds like the switch(es) below the keypad pad(s) are sticking or failing. Unfortunately, replacement keypads tend to be expensive, perhaps too expensive for the value of the oven. Search for replacement parts by your Make and model.

YOu need to lock the time you set and leave the oven connected to power at all times.

put in a lower wattage magnetron

Possibly an overheat condition causing a thermal cutout to open up then resets when cooled down. Make sure fan is running that cools the magnetron tube. Visit www.repaircllinic.com

Consult your users manual for specific instructions on oven programming issues. A manual can be located online at www.repairclinic .com if you need one.

As you didn't specify any specific model, one of the Samsung models uses this scheme to change power levels.

You begin by pressing the "Microwave" button once. Pressing it again will display different power levels, from low to high.

You'll have to call Samsung Customer Support. Samsung Call Center (1-800-726-7864).

Unplug it is about all

The SE error code indicates that you have a stuck key on the control keypad or a failed electronic control board. A technician will need to diagnose and repair this type of failure. Microwaves are inherently dangerous to service
