How To Check Microwave Capacitor. Again, you should receive a reading of infinity. The orientation doesn't matter, because resistance isn't polarized.
Once this short circuit is done, it is now as safe to work on your microwave as any other appliance so long as you keep it disconnected from the power. Turn the knob on your multimeter to “capacitance” mode. Micron through passage capacitors in the microwave are also tested by a tester.
Gently Slide The Screwdriver Forward Until It Reaches The Other Terminal, Holding It There For A Few Seconds.
On information on how to safely discharge the high voltage capacitor, please visit the link below: When the scoreboard is 1, the capacitors are operational. Micron through passage capacitors in the microwave are also tested by a tester.
Even With These Multimeters, We Can Test A Capacitor.
It is necessary to touch the conclusions of the device output of the magnetron and its body. To do this test, we take the ohmmeter and place the probes across the leads of the capacitor. This capacitor is charged to a high voltage.
If We Read A Very Low Resistance (Near 0Ω) Across The Capacitor, We Know The Capacitor Is Defective.
With your microwave unit unplugged, touch the blade of a well insulated screwdriver to one terminal. The rubber handles will insulate your hands from the metal. Before you start testing the microwave capacitor, make sure to star by unplugging the microwave from the power outlet on the wall.
A Phillips Head Screwdriver With A Rubberized Handle, A Multimeter (Preferably Digital), Rubber Work Gloves
Once this short circuit is done, it is now as safe to work on your microwave as any other appliance so long as you keep it disconnected from the power. They need to be replaced with new parts. Place an insulated screwdriver against the capacitor’s terminals to discharge it.
Unplug Microwave And Discharge High Voltage Capacitor.
In polarization, connect the positive terminal to a red multimeter probe and the negative terminal to a black probe. Method 2 checking a capacitor using multimeter without capacitance setting. If it is successful, you will hear a pop when the short circuit is completed.
