Here is the video on youtube. You must watch it if you are a Urdu to Hindi viewer: Here is the video on youtube. You must watch it if you are an English viewer: The microwave oven is a useful machine to preheat or cook food. The microwave oven is working reliably but now a days Chinese microwave oven have big front panel keypad failure. The keypad is breaking down in one year of less time. The repair is not easy and sometimes the replacement parts are not readily available then it becomes another problem. The solution to such a problem is a modification with existing easily available parts and some wire connections to the main board. The modification is a very robust an reliable work so that will never break down or if breaks down, the repair would be way easy and low cost. Here is a little detail with images is included for such a modification work. Most of the images are from the video associated with this blog post. Anyhow it will further explain the important
Here is a youtube video covering all these details in video: Sandwich maker or sandwich grill is a common house hold electrical appliance used in every house and every facility. They are daily use electrical appliances. They are of different make and model. One thing is common in all of them is the heating element and a sort of temperature controlling switch operated on some preset or selectable temperature range. The heating element are heated by line power and are switched off when the desired temperature is reached. By that way the grill or heating plate is heated and the toast put there is also grilled or heated by that temperature. Sandwich makers or sandwich grill are reliable equipment but some times they develop troubles. The result is no heating grill or heating plates. Normally there are electrical connection problem or temperature controlling switch problem. The heating element failure is also possible but that is a rare fault. So if a grill or sandwich
Test smd resistor using a multimeter Digit code for smd resistors Here is the video on this topic you can watch for further details: Surface mount resistors or SMD resistors are very commonly used in electrical and electronics circuits. They are found everywhere in all electronics equipment today. They have certain value in resistance or Ohms which is mentioned on them in the form of a digital code. Here the following image is showing a surface mounted resistors circuit where you can see the SMD resistors and the rest of soldering on the PCB. Her in this image you can see the surface mounted or SMD resistances with a digital code on them. The resistors have a specific value code on them. This code is easy to learn and off course easy to print on the small and tiny body of an SMD resistor. This code consists of three digits or three value alfa numeric code is also used. Sometimes this could be a four digit code also in case of very high precision resistors. We will only dis
