Microwave Oven High-Voltage Fuse – 5kV 0.9A
The 5kV 0.9A Microwave Oven High-Voltage Fuse is a replacement protection component designed for selected microwave ovens with matching electrical specifications. It is installed in the high-voltage circuit and helps protect the transformer, capacitor, diode and magnetron from excessive current or electrical faults.
If an abnormal current condition occurs, the fuse opens the circuit to help prevent further damage to the microwave’s high-voltage components. This listing includes the replacement fuse only and does not include a fuse holder or wiring assembly.
Product Features
- Part type: Microwave oven high-voltage fuse
- Voltage rating: 5kV
- Current rating: 0.9A
- Designed for selected microwave oven high-voltage circuits
- Helps protect the transformer, capacitor, diode and magnetron
- Interrupts the circuit during excessive current or electrical faults
- Suitable as a replacement where the electrical ratings and physical dimensions match
- Replacement for blown, damaged or open-circuit high-voltage fuses
- Supplied as the fuse only
- Fuse holder and connecting wires are not included
Common Symptoms This Part May Fix
- Microwave operating but not heating
- High-voltage circuit not receiving power
- Microwave stopping shortly after a cooking cycle begins
- High-voltage fuse testing open circuit
- Fuse visibly burnt or damaged
- Microwave making a loud hum without heating
- Magnetron not operating despite the control panel functioning
- Microwave light, fan and turntable operating but no heat being produced
Important Diagnostic Note
A blown high-voltage fuse is often caused by another electrical fault and should not automatically be replaced without further testing. The magnetron, high-voltage capacitor, diode, transformer and associated wiring should be checked before installing a new fuse.
Important Fitment Note
This fuse is only suitable for microwave ovens requiring a 5kV 0.9A high-voltage fuse. Before ordering, compare the voltage rating, current rating, fuse length, fuse diameter, terminal design and holder compatibility with the original component.
Never replace the fuse with one that has a higher current rating or bypass the fuse. Doing so may remove essential protection and create a serious fire or electrical hazard.
Microwave ovens contain high-voltage components that may retain a potentially lethal electrical charge after the appliance has been unplugged. Testing and replacement should only be carried out by a qualified appliance technician using the correct high-voltage safety procedures.
