I assume you have this in a motor home/RV that's where they were used mostly. That error code is not a standard code. If you call Samsung you will be told it has to be serviced by a tech and they don't know what the error code is. In 4 years I've never been able to find a answer to E A1
besides have a service tech look at it, and mostly/always they end up recommending replacement.
If someone else at FIXYA knows different I too would like to know.
Sorry..don't like being the bearer of bad news but I wouldn't want you to throw parts/service at something and end up replacing it anyway.
If "everything" works and your microwave just stopped heating, the problem might be with the internal door switches, the high voltage circuitry, or the circuit board or quite probalby your magnetron is dead. If you don't have the technical knowledge to repair microwaves, you should take it to a repair service for diagnostics.
This is a microprocessor problem in the appliance. It can often be reset by unplugging the device, waiting 10 minutes and plugging it in again. If that doesn't work, you will probably have to replace the appliance (cost to buy a new one in usually a lot less than trying to get it repaired).
looks like your control unit pcb is not having power, most likely a varistor blow up on the input power line to the board, just replace it and fix the melted track on the board.
If the oven is going dead, and coming back to life, I'd look for a bad connection on the door switches or thermal protector. If it's just the control panel, it could be a bad connection or failure of an electronic component on the circuit board. If it runs, but heats intermittently, it could have a failing magnetron or intermittent high voltage rectifier. If one of those components is failing, it will stop heating completely soon.

Normally You have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screw(s) you need to remove.
Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.
In some cases, you then have to gently rotate the handle to unlock it.

For simple, one-stage cooking, you only need to set the cooking time. The power level is automatically set to High.
If you want to set the power level to any other level, use the Power Level button.
1. Use the number buttons to set a cooking time. You can enter a time from one second to 99 minutes and 99 seconds. To select a time greater than one minute, enter the seconds too. (For example, to set a cooking time of 20 minutes, enter 2, 0, 0, 0.)
2. If you want to set the power level to a level other than High, press the Power Level button, and then use the number buttons to enter the power level.
3. Press the ENTER/START button to begin cooking. If you want to change the power level, press the STOP/ CLEAR button before you press the ENTER/START button, and then enter all the instructions again.
Does this happen while you are cooking on the range burners under the control panel?? These type microwaves have a heat sensor built into them in the area of the control panel bottom. If the microwave control gets too hot from cooking on the stove below it the heat sensor will turn the fan on to keep the control panel from getting heat damage. The fan should go off after everything cools off.
HAVE THE SAME PROBLEM WITH MY OVER THE STOVE SAMSUNG MICROWAVE. LOOKED UP ALL THE ANSWER'S AND CHOOSE THE ONE I THOUGHT BEST AND EASIEST. ITS A MOISTURE (STEAM) PROBLEM FROM COOKING ON THE STOVE. TAKE THE TOUCH PAD APART (AFTER UNPLUGGING AND FINDING THE VIDEO ON U-TUBE THAT SHOWS YOU HOW TO DO IT) ITS EASY. I JUST TOOK THE RIBBON (MINE IS GREEN) SEPARATED IT FROM IT SELF AND PLACED A PIECE OF PAPER IN BETWEEN SO THEY DON'T TOUCH. HAD TO DO IT TWICE BECAUSE I DID NOT SEPARATE THEM DOWN FAR ENOUGH. I ALSO BUT A PIECE OF FOAM IN THE PANEL UNDERNEATH THE CIRCUIT BOARD BECAUSE OF THE HUGE GAP FOR STEAM TO GET IN. IT'S LASTED 4 MO, THAN STARTED FLASHING SE OCCASIONALLY BUT BY OPENING THE DOOR AND PUSHING STOP ITS FINE. THIS HAPPENS MAYBE ONCE A WEEK. I THINK IF I GO BACK IN AND RE-SEPARATE THE RIBBON IT WOULD STOP AGAIN BUT IT'S REALLY NOT ENOUGH TO BOTHER ME. GOOD LUCK
Well the relay to energise the magentron is stuck on closed. You have main board problem. First check that board, the microcontroller is responsible for the relay via a switching transistor of FET. You have a shorted FET/TRN as well. Can't believe the tech did not check that. Thanks
Likely a microprocessor/control panel issue. Microwave ovens that sit over ranges often have electronic failures due to heat, humidity, and grease, from the range below, which come into contact with their main circuit boards.

Please post a new help request and be sure to include the full model number from the tag on the unit as well as details on your symptoms, such as what it's doping or not doing, and when & how the problem occurs.
Then we'd be able to give you free help.
I would say the "Start" pad your membrane keypad has failed.With the full model number, I could have likely given you very specific information, possibly even do it yourself repair.
If when you press the start button the turntable starts but no heat then magnetron is faulty otherwise if nothing happens then the touchpad itself is faulty.
