Yas November 14, 2015 for Model Number SMH1816W/XAA-0000 I plug the microwave (Samsung SMH1816W/XAA-0000), display is good, after 4-5 seconds the house breaker resets. When I plug in again, it works same as before. It means works for 4-5 seconds and then breaker resents. I also smell a very light smoke. I opened the case, the fuses are fine and there is no loosen wire. I checked the thermostats, one has continuity (the one that is closer to the right side) and the one that is behind the first one has no continuity. I read that the second thermostat should be discontinued (if I am correct). Do you think the problem could be from the control board? And, have any idea what the part number is?
1 Answer Yas, With the unit tripping the breaker after being plugged in for 4 to 5 seconds then the issue will be caused by a faulty control board. Read More...
Steve July 19, 2015 for Model Number smh1716s Microwave oven blows house breaker after 20 seconds. Draws 42 volts but o lay 24 volts into high voltage transformer. Cap has already been replaced.
1 Answer Steve, With this issue it will be one of a couple different things that could cause this. The first would be a bad noise filter assembly, the second would be a bad wall outlet or wiring and the 3rd would be a faulty breaker. You will want to check these things to make sure that they are good. Read More...
Dave May 23, 2015 for Model Number SMH9207ST/XAA-0001 Was using the microwave and opened the door after using it to heat up chicken and in the middle of the cooking cycle the unit just stopped working and now the unit does nothing at all , tried to plug in another out let and it still will not do anything at all. Any ideas ?
1 Answer Dave, You will want to check the fuse that is located on the filter assembly to see if it is blown. If it is then the likelihood of what is wrong would be that one of the door switches would be defective. Read More...
Pat February 20, 2015 for Model Number 401.85059010 I plug my microwave in, the display comes on then it requires you to set the clock then it's ready to run, I set the run time press start and it run's for maybe a second or two then loses all power and display and then powers right back up requiring me to start all over as if I just plugged it in having to reset the clock again..??
1 Answer Hello Pat. Look for any loose wiring connections in the unit. If none are found, you will need to order and replace the control board on the unit. Read More...
Jb January 27, 2015 for Model Number SMH7178STD We have a samsung microwave that just stopped heating and now makes a loud humming noise when running it. Any suggestions? Thanks.
1 Answer Hello JB. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron. Read More...
Tom January 08, 2015 for Model Number SMH1713S/XAA-0001 Hello. One year and 3 month old Samsung Microwave. Very simple and repeatable symptom: turn the microwave on level 10 for 30 seconds it makes a horrible buzzing noise the whole time. Turn the microwave on level 5 for 30 seconds and it buzzes horribly for about 20 seconds and then gets nice and quiet - operating correctly. As you reduce the heating level, the length of time of the buzzing noise gets shorter. Food heats just fine in all settings...it's just a terrible noise. People have suggested the magnetron or the diode or the transformer. Which one do the Appliance Parts Pros say it is? Thanks, Tom
1 Answer Tom, The most likely cause for this issue would be a diode but would be a good idea to replace the capacitor and diode at the same time as the capacitor may be having some bleed through which would damage the diode if this is the case. Read More...
Fred W January 05, 2015 for Model Number Samsung Uwave SMH9187B/XAA With door closed the unit made buzzing sound which quit after a short time. Unit runs but does not heat. Noted that one 20A fuse is now open. Checked diode connected from large capacitor to chassis on 20M scale on VOM and it shows open in both directions. What else can I check? Is the 250V 20A fuse an off the shelf item? Thought I would get a new diode which you show in stock and try that. Any advice? Thanks.
1 Answer Fred, The fuse comes as part of the noise filter assembly which is part number DE96-00400B. As for the diode, if it was failing it could make a buzzing noise which is not uncommon. Read More...
Abry October 20, 2014 for Model Number SMH1622S/XAA-0001 Was using vent fan we had oven on high and 3 of five gas range burners going the whole unit went off like it was unplugged. All at once no fan no panel lights, out like it is not even plugged in, power is good at plug. Thinking a safety thermostat thing maybe.
1 Answer Abry, You will want to pull the unit down and check the cavity thermostats to make sure that they have continuity. If not then they would need to be replaced. If they do then you will want to replace the control board on the unit. The thermostats are more likely. Read More...
Jack July 20, 2014 for Model Number 40185042010 Microwave heats, clock counts down correctly and unit runs for the correct amount of time. When not in use, the display will show random messages and beep periodically. The stop button can be pressed to allow a new cook time to be entered and the unit will cook normally. Every so often the key pad will stop working all together. Un plugging and plugging the machine back in will allow the key pad to work again. Perhaps a power surge has damaged an electrical part? Any ideas on which part? Thanks
1 Answer Hello Jack, This sounds like either a bad connection between the control and the touchpad or the programming in the EEPROM on the control board DE94-02302B is corrupted. I'm sorry but this part has been discontinued by the manufacturer and no satisfactory substitutions have been provided. You can contact www.corecentricsolutions.com to see if they support the control board for repair. Read More...
