Question about Sharp R-520LW Microwave Oven
Please be very careful when troubleshooting your microwave it can shock you even when it is unplugged from a power source. Take your digital multimeter and check your fuse. If ot is blown check diodes if it reads both ways it is bad. If you arent sure how to discharge the main cap please have a tech troubleshoot your microwave. Most likely it will be the diode if the fuse is blown. If not it is the big electrolytic capaitor shaped like an oval tin can please be careful with this component make sure you discharge it first before relaceing
