1 Answer Jose, with the microwave unplugged for 10 minutes, the magnetron, capacitor, diode, and magnetron would need to be inspected. The diode would be tested for continuity and will measure as having continuity when tested in one direction, and open when tested in the opposite direction (direction indicating from terminal to terminal). The capacitor would be tested for resistance to indicate if it is able to hold a charge. The resistance should start out at 0O and slowly climb to 9MO. The transformer will be tested for resistance and the reading would be based on what the full model number is as there are two variations. The magnetron filament would need to be inspected for any damaged portions. If these components test good, then the likely failure would be in the main control. For the most accurate part numbers, the full model number would be necessary. Read More...
Harvey May 12, 2020 for Model Number ME18h704SFS What part is a compatible replacement for my Samsung Microwave thermostat part #1505-Ksd-120LC?
Mike I May 02, 2020 for Model Number Samsung ME16H702SES Hello. My mircowave recently went out. No power at all. I took it apart, and tested all the fuse, thermostats, switches, etc. All seem to work as designed. While taking it apart and putting it back together twice, I noticed that the power came back on and then off. I powerd it up with the panels removed, and I found that I could turn it on/off by jiggling a wire to the thermostat labeled KSD-120LC. I pulled the thermostat out, and tested it for continuity, and it seems good. I think my issue is with the wire's female connector. This particular wire has a white cap over the female terminal attachment to the wire. Do you sell that part? What is the white cap for - heat protection? If not for heat or anything, can I just crimp a new female connector and be good to go? Thanks for all of your help!!!
1 Answer Mike I, the cap is used as an insulator to prevent possible arcing from terminal to terminal. While it is recommended that the main wire harness DE96-00740D is replaced, using a hi-temp insulated terminal is possible. Read More...
Roel April 30, 2020 for Model Number ME21H706MQG Microwave runs but not heat. I check the magnetron is good, the thermal switch on top of magnetron is good, Capacitor is new along with the diode which I thought were the culprit. So I proceeded with testing the Thermostat I see that this microwave has 3 thermal switches. The two behind the control panel, the one on the left-hand side 1509 KSD-140LC 70 has an open circuit, the one on the right hand 1509 KSD-140LC 0 is a closed circuit. I also have one on the top 1509 KSD-120LC 0 has an intermittent open-close circuit when I wiggle the prong while testing. Should all of them suppose to have a closed circuit? Can you please tell me which one to order. thank you.
1 Answer Roel, The thermostats you are testing would be fine except for the one with the intermittent open/closed. The thermostat should remain closed except for in the event that it gets too hot. Also, check the door switches as this could cause the issue. Read More...
1 Answer Roy, with the microwave unplugged and set for 10 minutes, the transformer WB27X10868, magnetron WB27X10735, and diode WB27X1160 will need to be tested. The transformer primary windings should measure .3O resistance, the secondary winding should measure 50-70O resistance. The diode would be tested for continuity in both directions, one way having continuity while the other way not. The magnetron would need to be inspected at the antenna tube to ensure that it is not burned out and tested for continuity from the filament if the tube to the magnetron housing. If these all test good, the failure would either be in the main control WB27X10871 or the capacitor WB27X10240. The capacitor can be tested for resistance and it should scale up towards infinite after starting with a low resistance, but this is not a guaranteed way to test the capacitor. Read More...
Nick April 25, 2020 for Model Number Me18h704sfs Recently my microwave turned off when heating something up. I have continuity at 2 fuses and 2 of the 3 thermostats. Id# 1605ksd-40lc70 came back open. What is the correct replacement number for this thermostat?
1 Answer Nick, One of the 2 thermostats located behind the control panel should read open at room temperature and the other will read closed. Test the door switches on the unit and if they check ok and all the thermostats and fuses check ok then this would be a faulty control board. Read More...
Me April 07, 2020 I have a Samsung microwave oven with the model ME21H706MQ. One of the thermostat fuses got burnt, the part number reads 1605 KSD 140 LC 0. What is the appropriate replacement part?
Robert March 30, 2020 for Model Number MC17J8000CS Hello, I have a Samsung MC17J8000CS microwave, the thermal fuse went out ( convection fuse I believe ) , the number on the part is, 1603 KSD-150LC. What part number do I need to replace it? Thanks.
John March 03, 2020 for Model Number Samsung SMH1926B My microwave oven suddenly shut down and now has no power. I have checked for continuity on a thermal fuse/switch that has a number 1207 KSD-40LC 70 stamped on it which is showing to be open (no continuity). (This fuse appears to be item #16 in the parts diagram.) My question is this thermal fuse blown and if so, what is the correct replacement part number? Thank you!
1 Answer John, Check the thermal that is next to it and it should have a closed reading. The 2 thermals that are on that bottom behind the control panel will be one open the other closed. Check the fuse on the filter board to make sure that it is not blown and test your door switches. The part number for that thermostat is DE47-20034A. Read More...
Carey February 17, 2020 for Model Number SMH9187ST/XAA Hello, My thermostat went out and i am trying to find the correct replacement part. the numbers on the top read "1003 KSD-150LC" Is this the correct part? There are several of these with different part numbers on them. thank you.
1 Answer Carey, the thermostat on the magnetron is going to be part number DE47-20007B and is normally a closed circuit. The thermostat on the right just behind the control is part number DE47-20059B and the left-hand thermostat behind the control is part number DE47-20034A. Read More...
