Microwave comes on when i open door? When we close it shuts off then it will run as normal when you put cooking time as it should .
For model number SMH1622S
Hello Sam, Thank you for your inquiry. We have researched the model number you have provided and would recommend checking the door switches. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, we have videos available to assist you. For safety reasons, since the microwave capacitor can still store electricity even when the microwave is unplugged, it is usually advised that you discharge the capacitor before any attempt at repair.
We hope this helps and if you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!

UNPLUG THE MICROWAVE FROM THE WALL. Start taking it apart. I use my phone to take a picture of any thing I remove, unscrew or disconnect, especially wires, BEFORE I disconnect them. Thee pictures serve as a reference when I go to reconnect and reassemble. If I am uncertain then I check the picture. Good luck!
I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.
Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those w

Now the Microwave works just like new! Cost me less than $100 for all parts.
