In this article, Repair Clinic will address how the microwave’s high voltage circuit works and two different ways you can test a microwave capacitor to determine if the part is malfunctioning. However, replacing any part of the microwave heating apparatus comes with a uniquely dangerous task that you absolutely must do first: discharging the microwave capacitor.

Quote from: james_s on January 24, 2019, 02:05:48 am There aren't many consumer devices with a bigger HV capacitor than a microwave oven.
We aim to answer you quickly, normally during the week the longest you will weait for a response is an hour at most but, often we're answering you in minutes.
So, if your capacitor is faulty, and the motor is struggling to work, then this replacement microwave high voltage spare is for you. The microwave’s capacitor works with a diode to convert the alternating current power output of the transformer to direct current (DC), increasing the voltage to nearly 5,000 volts. Gently slide the screwdriver forward until it reaches the other terminal, holding it there for a few seconds. MOS caps are different from MIM caps in that the base "metal" in MOS is a semiconductor (silicon), which provides electrical contact through the backside. Microwaves are made up of 4 primary parts: The power transformer, the magnetron, the capacitor and the one-way diode.Ces avis vous aideront à trouver le meilleur microwave capacitor dans une large gamme, quel que soit votre budget, qu'il s'agisse de marques de qualité ou d'articles à prix abordable. In some videos where I saw guys tearing down things like microwave ovens, they say that the big caps inside can kill and therefore should be shorted carefully before you touch anything around them.
If the capacitor is unable to hold a charge or the charge is too weak, the microwave may still “turn on” and the turntable may still rotate, but the alternating current sent to the transformer will not be converted to direct current, so no high voltage will reach the magnetron which will be unable to send out the electromagnetic waves to heat up the food.Whilst we have tried our best to cover the most common questions here, there are some product and location-specific exceptions that may also result in additional charges. Warning: The voltage in a microwave can cause injury or death, only attempt if you have previous experience or training. Please do not arrange to have a tradesman on site until after your goods have arrived and you have checked them (We will not pay your tradesman's costs in the event that the item is damaged in transit or not suitable for any reason).
Linear regulators always need at least two electrolytic caps, one on the input and one on the output, to remain stable. With Smeg you will quite often find many of the same spare parts used by other manufacturers or brands and, using their part which is exactly the same, can offer a considerable saving on the cost or a replacement part.If necessary, calibrate the analog-style ohm meter by contacting the ends of the meter leads together while adjusting the needle to read “zero”, then rotate the meter’s range selection dial to a setting of 1,000 ohms or higher. A capacitor is discharged by creating a short circuit between each of the two capacitor terminals, and between each terminal and the chassis. If you replace the capacitor without replacing the centrifugal switch, you will be replacing the capacitor again in no time. This is absolutely necessary once you have the case off the microwave to make sure you are at no risk of being electrocuted. Place one meter lead on a terminal and the other lead against the capacitor’s casing, then move the first lead to the other terminal, keeping the second on the casing.
