Why are microwave fuses ceramic?
Like most appliances that produce heat, your microwave comes equipped with a ceramic fuse. When the appliance overheats or suffers a dangerous power fluctuation, this fuse will blow to prevent fire or excess damage to the microwave by cutting the power.
Where is the ceramic fuse in a microwave?
The ceramic fuse is located inside of the cabinet near the entry point of the power cord. Remember to unplug the cord before attempting any repairs. You can check the fuse for continuity with a multi-meter.
What kind of fuse does a microwave use?
Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron. This is a 20-amp fuse, and is used to power your microwave.
Do you need a special fuse for a microwave?
Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.
Are microwave fuses fast or slow?
Answer:Microwave fuse should use slow-blow type because its loading will increase much when microwave starts. It needs a little overload when machine starts(only a short time). So some people replace it with fast-acting fuse and cause burnt frequently.
Can you replace a 20a 125V fuse with a 20a 250V fuse?
For example, a 125V fuse can be replaced with a 250V fuse of equal amplitude while the voltage of the application is 250V or lower, but a a 250V fuse can’t be replaced with a 125V fuse of equal amplitude if the voltage of the application exceeds 125V.
Why do fuses have voltage ratings?
The voltage rating of a fuse is a function of its capability to open a circuit under an overcurrent condition. Specifically, the voltage rating determines the ability of the fuse to suppress the internal arcing that occurs after a fuse link melts and an arc is produced.
What is a 250V fuse?
Semiconductor Fuse – 250 Volts The 250 volt semiconductor fuse is a current limiting very fast-acting fuse rated to 250 volts AC and up to 250 volts DC. Current ratings range from 1 to 2,500 amps. The maximum interrupting rating is 200,000 amps AC and 100,000 DC. These High Speed Fuses are UL Recognized.
