Quasar Microwave Capacitor Replacement

はじめに

If the microwave does not power on correctly, the capacitor may be at fault. Always use caution when working with electrical devices.

    • Old electronics collect dust, no matter if they are in active use or being stored. It is recommended to clear out some of the dust prior to affecting any complicated repairs. Use compressed air, and wear a dust mask and goggles. Always use precaution when working with old electronics.

    • The capacitor stores a small amount of electrical energy. Discharge capacitor by placing a screw driver across the terminals. Use a screwdriver with a non-metallic handle and a shaft that is longer than 4” (10.75mm) Touch the metal shaft of the screwdriver simultaneously to both metal terminals of the capacitor. There should be a spark.

    • If the capacitor sparks, you can stop reading here. The spark indicates that the capacitor is working properly. If the capacitor does not spark, read on to Step 6.

    • Place the multimeter on resistance mode and test the resistance of the capacitor.

    • If the resistance increases/decreases, the capacitor is working fine. If the resistance of the capacitor reads 0 or over several kilo ohms, the capacitor needs to be replaced.

    • Locate the transformer. The capacitor cannot be removed without removing the transformer first.

    • Locate and unhook all wires connecting the transformer to the rest of the microwave.

    • Take note of where each wire connects before disconnecting. Wiring a microwave incorrectly can cause serious damage.
