Question about Samsung Microwave Ovens

1 Answer

Microwave won't stop running

I have a Samsung SMH1816S that will only turn off if unplugged. It did not give me an error code, but if I shut the door it runs, and heats water, even though the light is not on and the turntable is not going. I can use the control panel to set time, and then the light will turn on and the turntable will go, but once it beeps that it is ended, the microwave goes dark but keeps running and heating. The only thing that stops it is opening the door.

There's a ghost in your microwave, call ghost buster. Seriously, the problem is the control panel. (((((the microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. That's more than 30 wall outlets combined.
Replacing electronic parts in a microwave oven can be extremely dangerous.))))))) tank you

SOURCE: NN-T990SA Panasonic Microwave Stopped Heating

This model uses an inverter to produce high voltage instead of a convential transformer system. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Some manufacturers do not encourage or assist technicians to repair microwave inverters. Most offer the inverter as a whole assembly. But sometimes that is actually cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized repair shops and ask then specifically about inverter repair and inverter replacement costs for your model number.

SOURCE: Microwave runs with door open

I would say you have a failing door switch or the mount which holds your door switch is loose or broken. In most designs, it is the upper door switch that will produce these very symptoms when it is intermittent or its mount is broken or loose. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. Slamming the door, damage during shipping or transportation and sloppy manufacturing techniques or materials are the primary causes of trouble with the door switch mounts. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

SOURCE: Microwave turntable won't stop running

This is usually caused by either a bad door switch, but may instead be a loose door switch mount or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Mod SMH1816S Shows SE error only 2 yrs old How to fix


Unless there is grease, moisture, or some other foreign material deposits on your control circuit board, "SE" means you have a shorted membrane keypad.

For the official repair information as per the Samsung bulletin, see http://www.microwavecontrol.com/samsung_se_error.htm

Turns on when door opened


There is an power interlock inside the oven that breaks the power connection to the magnetron when the door is open. Most likely, something is stopping the switch from opening.

Check for a small plastic probe on the door that may have broken off inside the oven keeping the circuit made. Otherwise, open the oven and see is some foreign object is keeping the connection made or if the interlock needs to be cleaned out so it can function.

Repairman just diagnosed mine as a bad display board, it quit working while nobody was even home, and cost $269 with a $70 service fee. The microwave is less than 2 years old and only cost @$400 new. I was lied to by the salesman when I made the purchase (imagine that, a salesman lied to a customer) he told me these were very good and reliable microwaves and that I should get years of service out of it, what a crock... I will never buy another Samsung appliance again, they have many many bad reviews and are made with inferior parts. I will stick with Kenmore kitchen products from now on!!!
