I have a GEJVM1640WB002 microwave that was manufactured in October of 1999. I have had it since November of 2001. Last night while trying to warm a very late night sack, the microwave produced some very intense crackling sounds and gave off a very foul odor. After tearing into the microwave, I found one side of the transformer was burnt crispy. Obvioiusly the transformer needs to be replaced. Any idea what the cause may be? After looking on the GE website I found the GE P#WB27X10254 transformer to be an outrageous $146.35. The transformer itself is a Samsung SHV-1640UC. It has the words Dong Yang Power Systems INC., LLC on it as well and another part number J1012HP. Does any body know where I can but this transformer with out shelling out all that money to pad GE's spare parts departments profits? I know large companies make bank off of spare parts orders.
