Question about Samsung MW1080STA Microwave Oven

1 Answer

Samsung MW1080STA Microwave Oven

Samsung Microwave (model MW1080STA) sometimes stops running within a few seconds of pressing "Start". The display then shows a string of "8"s. Pressing "Pause/Cancel" clears the "8"s from the display and allows the oven to be restarted. Sometimes this process occurs a few times before the oven eventually runs to completing of the desired cooking time. Less frequently the keypad becomes inactive after the "8"s appear and the only way to get the over to run is to unplug it and then plug it back in. How can I fix this?

This is due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

How to stop my microwave from coming on when door is closed


There are no really user-serviceable parts in a microwave oven.

They are very dangerous to work on. As a result, it takes special tools to even open the case.

I'd just trash it - it might burn your house down.

Replacements are cheap. Even one from a Thrift Store would be better than a potential fire-starter with a mind of it's own!

GE spacemaker microwave turns off during cooking and display goes black


Step 1:


Door Switch




If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently

Step 2:

Main Control Board




If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.


Touchpad and Control Panel




If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.

Touchpad




If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer




If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.

Thermostat




If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostat

E41 and does not work


If your microwave is displaying an error code cycle the power to the microwave by either unplugging the unit, or cycling the circuit breaker.

If the above suggestion does not work,and the error code returns, your microwave will require service.

My child locked the microwave pad. How do I unlock it?


The operation manual is available for free download from Samsung at this site: http://downloadcenter.samsung.com/content/UM/200305/20030529145700437_MW5592.pdf
The answer to how to lock and unlock is on page 15 of the manual. It's instructions are: 1. Press the '0' button, the display will show: "PRESS 1- DEMO 2-CHILD LOCK"
2. Press the "2" button, the display will show: "PRESS START"
3. Press the start button and the display will show "LOCK" then returns to the time of day.
At this point the microwave can't be used. To unlock, just repeat steps 1-3.
Hope this helps

The best method would be to use a food thermometer to measure the temperature of the food, and change the cooking time to get to the correct temperature.

Microwave displaying SE in the display panel, it is only 5 months old.


An SE error on a Samsung microwave means you have a shorted membrane keypad.
If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.
