Thankyou very much sir.. Great way of teaching.. This is the video I was searching on you tube.. I ve subscribed your channel.. I hope I will find more videos from your channel like this great one.. 👍👍👍👍👍👍
i have panasonic nnsd997s aph, the fuse is gone, sometimes when i start microwave, there will be no light, spin, and sound (no power). is it because short switch is bad and cause fuse to blown?
Great , the monitor switch keep failing can we bypass it permanently or any alternative solution , the fuse keep burning , I replaced switch but sometimes if we close or open the oven quickly the fuse burns Any solution ?
Good day Am Febian from Nigeria, I love your pattern of teaching,pls I have small challenge,what is the value of the zener diode that is connected to the output of relay in microwave power circuit
Very good video. Sir good day can you give the exact voltage of transformer from control circuit of microwave oven samsung brand they have six wire secondary two black, two yellow and two white. I dont know those voltage at secondary.
relay 1 and relay 2 explain, in my oven, i start the oven heating with no issue but the light and motor not working, i checked the switch good but no supply coming what is the issue
Thanks for a nice instructive video. But still my fuse blows everytime I open the door. With 3 interlock switches checked, magnetron, HV capacitor, diode, transformers all checked good. What do you suggest?
My oven suddenly some sound coming I open and check the fuse damage I replace it, then start the oven it working but the plate mote fan light not coming to power what is the issue
Can you help me with the FA and F wiring diagram? I am getting so many conflicting answers and diagrams on where they are supposed to go. does it matter?
Hello Sir...can u give me the cause why microwave not heating? Checking has been done: HV diode ...ok Capacitor ..OK Magnetron .. OK If PCB problem..whats the main cause? Tq
good video... thanks for sharing.. I was able to fix my issue.. The issue was bit weird. Problem: Once you open the door, the light comes up and the plate motor and fan starts working(but not the Magnetron). If you close the door and start microwave with normal inputs, the display shows normal and clock starts working but the magnetron did switch on, neither the light and motors. I was able to narrow down the issue. All the latch switches were working fine(2 latches are N.O and one is NC). The Main relay was not closing. While door was open(Ideally it should). Tried check after unplugging the relay contacts and checking the continuity. I kept the door opened and tried closing the main rely using jumper and now only cabin light was coming up as expected under normal working state(primary side of transformer unplugged to be on safer side). Diagnosing the main relay issue in PCB. Removed the pcb and checked the relay. It was working while I provided an external 12v supply. (kept the correct polarity - reverse of freewheel diode. If trying, better to desolder relay and check using external 12v) I had to check the relay drive transistor. It was working okay... The 12v positive was connected to relay one side and drive transistor was enabling the ground pin to relay to switch on. I could see the ground continuity was not proper a the transistor end. Traced the track to the common ground pin and I could see using my meter, it was open. Tracked the line to find the broken area and soldered a jumper for proper ground. Tested the board using supply. Now the relay started working.... Plugged in back all the relay ping and tested..... viola... !!! it started working perfectly.. Thanks a lot for sharing... you saved me a lot of money... I wrote the troubleshooting steps to help someone facing similar issue ... cheers guys..
Thinks Dosto. The display power of my microwave oven does not come.When the oven door is opened, then the lights come on and the tray motor is driven. I have no idea what the problem is.Please advice me or help me.

ഞാൻ channel subscribe ചയ്തിട്ടുണ്ട്. ഞാൻ ഒരു technician ആണ്. Microwave ovens repair ചെയ്യുന്നുമുണ്ട്. പക്ഷേ ഇപ്പോഴും ഒത്തിരി സംശയങ്ങൾ ഉണ്ട്. 1) ഒരു കമ്പനിയുടെ Magnetron (Eg.Daewoo) മറ്റൊരു കമ്പനിയുടെ (eg.Samsung) oven ൽ ഉപയോഗിക്കാൻ പറ്റുമോ .... 2)Class 220 ന്റെ Microwave Oven Transformer (MOT) ക്ക് പകരം Class 200 അല്ലെങ്കിൽ Class 250 ന്റെ MOT ഉപയോഗിയ്ക്കാൻ പറ്റുമോ .....? 3) ചില ovens ൽ Magnetron ന്റെ കണക്ഷൻ seperate connectors ഉപയോഗിച്ചാണ് കൊടുക്കുന്നത്. ഇത് തമ്മിൽ മാറിപ്പോയാൽ എന്തെങ്കിലും കുഴപ്പം ഉണ്ടോ .....? 4)Microwave section ൽ ഉപയോഗിക്കുന്ന diode രണ്ട് തരത്തിൽ കണ്ടിട്ടുണ്ട്. Sylendrical shape ഉം Square shape ഉം. Cylendrical type ന് പകരം square type ഉപയോഗിച്ചാൽ കുഴപ്പം വല്ലതും വരുമോ ....? 5)Samsung ന്റെ main PCB ൽ നിന്ന് ഒരു strip, oven ന്റെ body ൽ screw ചെയ്ത് വച്ചിരിക്കുന്നത് കാണാം ഇതിന്റെ ഉപയോഗം എന്താണ് ......?
മാഗ്നട്രോൺ ഫിറ്റിങ് മാത്രം ശ്രദ്ധിച്ചാൽ മതി, എല്ലാം മാഗ്നട്രോൺ ഉം ഒരു പോലെയാണ് പ്രവർത്തിക്കുന്നത് ഫിറ്റിങ് മാത്രമേ ഉള്ളു വ്യത്യാസം പാന്റ് കാറ്റ് ഗ്രീക്കു കേറി പുറത്തിറങ്ങുന്ന രീതിയിലായിരിക്കണം ഫിറ്റിംഗ്
ഇവിടെ micro wave oven repair വളരെ കുറവാണ്, ഏതായാലും working പറഞ്ഞു തന്നതിന് ആയിരം നന്ദി, RAJASEKHARAN PALAKKAD 🙏🙏🙏

Can I get full wiring diagram of Whirlpool magicook 22c..?
Sorry sir very difficult
i have panasonic nnsd997s aph, the fuse is gone, sometimes when i start microwave, there will be no light, spin, and sound (no power). is it because short switch is bad and cause fuse to blown?
Micro oven door switch may be damage. Microwave oven taking high amp's also going main fuse
Great , the monitor switch keep failing can we bypass it permanently or any alternative solution , the fuse keep burning , I replaced switch but sometimes if we close or open the oven quickly the fuse burns
Any solution ?
Normally microwave oven taking 6 ampere
Temporary you can cancel that switch
Thanks , my middle switch was faulty and I replaced it it is working ok
V good
Thanks
Good day Am Febian from Nigeria, I love your pattern of teaching,pls I have small challenge,what is the value of the zener diode that is connected to the output of relay in microwave power circuit
First you try 12 V zener diode, first you check relay how many volt, sem v zener diode you can use ( relay operating voltage )
moniter switch for what you in vedio fuse damage switch also damage ?
Pl explain proggramig pcb
very good chatta
good morning sir... what is the trouble if the micro wave oven does not produce heat... working but not cooking... pls reply..
Transformer output there is one fuse check that one.
Check Transformer primary voltage. Don't try output voltage. Fuse is OK then you check the Magnetron
Marca y Modelo ???
Excellent
Good day sir do you have any automatic washing machine any brand wiring diagram and full video demo ?thank you
ഈ മേഖലയിൽ എനിക്ക് പ്രവർത്തി പരിചയമില്ല
Very good video. Sir good day can you give the exact voltage of transformer from control circuit of microwave oven samsung brand they have six wire secondary two black, two yellow and two white. I dont know those voltage at secondary.
Don't try to measure the voltage transformer ( Transformer output is high voltage )
First you check Transformer primary voltage 220 volt is ok, after close the power discharge the capacitor check all all component
One easy method, check the working amp's. good condition working micro oven taking 6 A, Magnetron not working taking 3 or4 amp's
samsung microwave . problem -

Thanks sir
Thank you ji
I found one oven board once we switching on display will be off few second then come back 000
Ifb. Oven roof heating fan & pcb fan does not work,,please advice
Can you help me with the FA and F wiring diagram? I am getting so many conflicting answers and diagrams on where they are supposed to go. does it matter?
Okay
What is your doubt ask me I will try to explain
What you want explain I will give you the answer
Low voltage transformer output voltage, how much??
Means PCB different model different voltage. 5 v, 12 v
good

Men PCB maybe some printed damage. Or door switch
Thinks Dosto.
The display power of my microwave oven does not come.When the oven door is opened, then the lights come on and the tray motor is driven.
I have no idea what the problem is.Please advice me or help me.
Main PCB maybe print fire/ broke. open main PCB and check
Please give circuit diagram complete of micro oven
Microwave oven diagram almost 99 % same
