When it comes to microwave diodes, the valve voltage often exceeds 3 VDC. This is where many digital multifunction meters fall short. These meters, equipped with only a 3 VDC battery, cannot accurately assess the condition of the diode. To overcome this limitation, we recommend the use of a traditional analog meter. Its 9 VDC battery allows for a more precise and reliable test. To further clarify, our production photos offer a detailed guide on how to perform this test. Rest assured, we provide you with Generic Microwave High Voltage Diodes, a pack of 2 PCS, designed to meet your needs. Now, let's tackle some frequently asked questions: Question 1: Is this diode compatible with most microwave high voltage diodes? Answer: Absolutely. Most home microwaves have a high voltage diode with a withstand voltage of 12kv and a rated current of 350mA (0.35 amp). Some models may have a higher rated current of 450mA, but typically, they use the CL04-12 diode. Question 2: What happens when a microwave diode fails? Answer: When the diode breaks down, the microwave will no longer heat food. Additionally, the high voltage fuse located after the transformer is likely to burn out. Question 3: How can I determine if the HV diode is broken? Answer: First, inspect the fuse on the low voltage side (power input side) for any signs of burning. Then, check the high voltage fuse located after the transformer. If either fuse is burned, it's a strong indication that the HV diode has failed. Finally, you can use an electrical meter to confirm the condition of the diode. Before proceeding with any tests or repairs, remember: Safety is paramount. Always ensure that the power is off and that the high voltage capacitor has fully discharged. It's crucial to check the terminal size of your original diode. Some newer microwaves use a 3/16-inch female spade terminal, whereas this model employs a 1/4-inch standard. Offers diodes with a 3/16-inch female spade terminal to cater to your specific needs. We pride ourselves on providing top-notch products and services. Rest assured, with Ohmmonburged, you're in good hands.
