The diode in your Roper microwave has an important job it converts the electrical power from the transformer, changing it from one form (AC) to another (DC), and doubles the voltage to about 5,000 volts. This high voltage is what gives the magnetron, the part that heats your food, the power it needs. If the diode gets damaged or burns out, it can't provide the necessary voltage to the magnetron, which means your Roper microwave won't be able to heat your food. Sometimes, you can see that the diode is visibly burnt. To check if the diode is the problem, you can inspect it. If it looks burnt, it's time for a replacement. But if you can't tell just by looking, you can test it with a multimeter or a 9-volt battery to see if it's working as it should. Remember, Roper microwaves can store dangerous amounts of electricity, so it's best to let a licensed technician handle diode replacements for your safety.
