Why does my microwave turn on when the door is opened?
It is supposed to. The light comes on and the fan comes on in readiness for food to be placed inside and the microwave energy source to be energised. Then the cooking starts.

Emmerson turns on and counts down but no cooking happens.
If your Emerson microwave is turning on and counting down but not actually cooking or heating the food, there could be a few potential causes for this issue. Here are some steps you can take to troubleshoot the problem:
- Check Power Levels: Make sure the microwave's power level is set to the desired level for cooking. Some microwaves have adjustable power settings, and if it's set too low, it may appear that the microwave is running but not cooking properly.
- Door Interlock Switches: Microwaves are equipped with safety interlock switches that prevent the microwave from operating when the door is open. If any of these switches are malfunctioning or not engaging properly, it could prevent the microwave from cooking. Ensure that the door is fully closed and the switches are working as intended.
- Turntable and Support: If your microwave has a turntable, make sure it's properly seated on its support and able to rotate freely. If the turntable is not turning, it could result in uneven cooking or no cooking at all.
- Magnetron Malfunction: The magnetron is the component responsible for generating microwave energy for cooking. If the magnetron is faulty or not functioning properly, the microwave may appear to operate but won't actually heat the food. A malfunctioning magnetron usually requires professional repair or replacement.
- High Voltage Diode or Capacitor: The high voltage diode and capacitor work together to convert the high voltage output from the transformer into microwave energy. If either of these components is defective, it can prevent the microwave from cooking. Again, professional repair may be necessary.
- Control Board or Circuitry Issues: A malfunctioning control board or other electronic components could also lead to a situation where the microwave appears to operate normally but doesn't actually cook. If you suspect control board issues, it's best to contact a professional technician.
- User Manual: Double-check the user manual for any specific instructions or troubleshooting steps related to cooking issues. The manual may provide guidance on common problems and their solutions.
If you've checked these common issues and the microwave still isn't cooking, it's advisable to stop using it and contact Emerson customer support or a professional appliance technician for further diagnosis and repair. Microwaves contain high-voltage components that can be dangerous to work with, so it's important to prioritize safety and seek professional assistance if needed.

A malfunctioning control panel or membrane can cause erratic behavior in your microwave oven. If the control panel is not registering the start command correctly, it may interrupt the cooking cycle. Try cleaning your membrane and control panel with a soft and damp cloth to remove the dust.
If cleaning doesn't resolve this issue, try resetting the microwave oven by unplugging it from the power source for a few minutes, and then plugging it back in.
The microwave may not generate the required heat to cook the food properly if the magnetron or high voltage capacitor is defective. This could lead to the timer counting down without any heating action.

The transformer that supplies the magnatron is fed from the same part of the machine that feeds the turntable motor.
The turntable motor is fed through one of the door safety switches.
Check the door switches and feed fuse. If a diode pack has failed, that will blow the fuse or even damage the switch as well.
