Modern Maid Microwave producing a burning smell

Common solutions for: Modern Maid Microwave producing a burning smell

01 - Modern Maid Microwave Waveguide Cover
The waveguide cover might be damaged and arcing or burning. If this is the case or if the cover will not stay in place, replace it with a new one.

02 - Modern Maid Microwave High Voltage Capacitor
The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. If the capacitor shorts out, the line fuse or circuit breaker may trip. To determine if the high voltage capacitor is defective, test it using a VOM meter with a capacitance testing capability. (“Warning: The microwave oven can store a lethal amount of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due ...to the high running voltage and the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the high voltage capacitor.)

03 - Interior Cavity not Clean
To avoid food splatter inside the microwave cavity, food should always be covered when cooking. Food that is left on the interior of the microwave can continue to cook each time the microwave is used. This can eventually cause a burning smell. Wipe up any spills or splatters after each use.
04 - Modern Maid Microwave Door Switch
Most microwaves have three or four door switches. When the microwave door closes, the door switches actuate in sequence to ensure that the door is closed properly. If the door switch has burnt contacts or the terminal connections are loose it will produce a burning smell. Inspect the door switches. if the switch smells burnt or has burnt connectors replace the door switch. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the micro...wave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace a door switch.)

Common Solution
05 - Modern Maid Microwave Diode
The diode converts the AC power output of the transformer to DC, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron to heat the food. If the diode burns out, the magnetron won’t receive enough voltage to operate, preventing the microwave from heating. When the diode fails, it is often visibly burned out. Inspect the diode and if the diode is burned out, replace it. If inspecting the diode proves inconclusive, test it with a multimeter that uses a 9-volt battery or... put a 9-volt battery in series with the diode. When the leads are reversed, the diode should only have continuity in one direction. (Warning: The microwave oven can store a lethal amount of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the high running voltage and the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the diode.)

06 - Modern Maid Microwave High Voltage Transformer
Microwave ovens produce a very high voltage in order to power the magnetron antenna, which emits the energy that cooks the food. When a high voltage transformer fails, it will usually arc and have a burning smell.
