...if you have a amp probe you can check the amps at the wires powering the transformer. if you have less than 12 amps, and 110 volts at primary side of transformer change the magnetron and ...
Question about LG Microwave Ovens
check transformer resistance. it is working normally. why it always blows fuse if i install this transfo Change Bridge Rectifier Diode And Capacitor Without Test by Meter,Some Time it will licks,Check
...problems. I found that no power to the the control board usually meant a transformer issue. I checked the leads on the transformer (with a meeter) and found that it was shot. Now I need a ...
transformer, put your digital meter on ohms and put the test leads across the capacitor remembering to unhook the one side to prevent misleading readings, If cap reads .2 ohms or less it is defective,
...transformer can be tested. All transformers are a/c. Try this first: Unplug the unit. Using a multimeter set on ohms, low scale, check across the plug. You should get resistance. If op4en (no needle ...
...transformer is partially shorted. If this is the case it will burn out fairly soon. To check use the ohmmeter again to get a good reading on the secondary and filament windings, compare these to the ...
...check out if the 220V (Europe) volts feeds the transformer. You must remove the cover, put a glass of water inside the oven, turn on for 3 minutes and measure the tension that come to ...
check the transformer is receiving a good supply before you spend more money. Beware of the transformer secondary that, if it is working, produces a dangerously high voltage (typically 2 - 3000 volts)
Check diode forward and reverse. Test output voltage from power control board to transformer. Test transformer coils. Best of luck and play safe; dont test voltage output from the transformer, voltage
