Microwave does not heat
So, your Samsung M1712NR microwave oven has broken. Do-it-yourself repairs begin with a disassembly. Unscrew the back cover of the furnace. We call the fuses and the winding of thermostats with a multimeter. If an open circuit is detected, the fuses must be replaced. Check the magnetron chain and the filament. We call the capacitor and its fuse. We find that the latter burned out, which indicates a short circuit, and the capacitor resistance is 2 ohms.
Thus, we found out that the fault lies in the capacitor on which the short circuit occurred. We remove it. We select a new capacitor at a rating similar to the old one, and replace or restore the capacitor fuse. Check the oven.
Tip: To protect yourself from microwave radiation, do not turn it on without a lid. Earned? So the repair is over.
Microwave sparks inside
If your Samsung ME713KR / BWT equipment has broken down , then before you repair your Samsung microwave oven yourself , do not forget to unplug it. The first thing you need to pay attention to in case of such a breakdown is the magnetron screen. It is in most cases made of sheet mica. The magnetron screen is located on the side wall inside the microwave. It is made in the form of a lining and is fastened either with latches or with self-tapping screws.
Under the screen is a hole through which rays from the magnetron enter the microwave. Having removed the plate, we find traces of burnt mica on it. It is for this reason that the furnace sparks. The easiest way to troubleshoot a problem is to make a new screen from sheet mica and replace it.
In addition, you need to pay attention to the condition of the metal in the place that was covered by the screen. If the microwave oven worked for a long time with burnt mica, then both the metal and the magnetron cap could burn in the place of damage to the screen. Then you have to remove the protective cover of the microwave, get to the magnetron cap and determine if it needs to be replaced or not.
The plate does not spin
There is another old model of the microwave - Samsung MW 87 GPR-G. It happens that a plate does not spin in it. This is one of the most common technical malfunctions, which, if desired, can be eliminated by repairing the Samsung microwave oven with your own hands. Most likely, in the furnace, the rotation motor of the pan broke, which must be replaced.
Put the microwave upside down. Remove the cover that closes the engine. Disconnect the connection contacts. We turn off its fastenings and remove the engine. Having picked up a new engine, open the door of the microwave oven and look at the position of the drive sleeve. On the motor shaft there is a cut-slot. The sleeve is fixed in it. When installing the engine, it is necessary that the slot on the sleeve coincides with the slot on the shaft. Turn the sleeve by hand until it is put on the shaft. We fix the engine, put in place the terminals and the cover. DIY repair of a Samsung microwave oven with such a malfunction is quite easy to carry out.
Touch keyboard does not work
How to repair a Samsung microwave oven with your own hands if the Start button does not work? In this case, the touch panel is most likely out of order . This is due to moisture, the contacts are oxidized, and some of the buttons stop working. In addition, the touch panel wears out over time and requires replacement.
Remove the top cover and control unit. Disconnect the board. We unstick the touch panel under warm air. We wipe the contacts, replace the new board. We return to the place the control panel.
The microwave does not turn on
You can repair your Samsung GE83KRW-1 / BW microwave oven yourself . Remove the cover, check the integrity of the network cable with a multimeter. Next, with his help, we check the integrity of the fuses in the continuity mode. If we do not detect an open circuit, continue to test. We call the resistors and the control panel. Next, check the switches on the panel. We find a broken switch element. When the door was closed, this element did not press the button, respectively, the contact did not close, and therefore the microwave did not work. We repair a broken switch, if it allows the quality of plastic and glue, or we replace a failed element. Putting the stove together.
Faced with poor or unscrupulous service in a repair shop, some consumers are wondering how to repair a Samsung microwave oven with their own hands. To fix the breakdown is quite realistic in most cases. To do this, get acquainted with the device of the microwave oven and the principle of its operation.
