A high voltage fuse HVFuse WD900 microwave oven Galanz put blown, was burned after replacement boot, check the high voltage circuit seems to be no damage to the components.5Tcservice manual download site

This failure is mainly caused by high voltage circuit overloaded, a common cause of severe leakage or short circuit in the presence of high-voltage circuit, generally high-voltage capacitors and high voltage diodes damage is the most common enemy in the maintenance check should first focus on capacitors and diodes doing so can often have a multiplier effect. If the fault is not in the high-voltage capacitors and diodes, and then check the other high voltage circuit components and circuits, focusing on high-voltage transformer parts, transformer damage is usually more common.5Tcservice manual download site
