Report "I own a subway store, we use a turbochef tornado i believe, there are a few parts that need to be replaced (i had to buy them myself, and try to replace them myself, because i cant afford to pay for service, its extremly expencive). i replaced a few parts before including waveguides. parts that i need alittle help with are ngc 3017 and ngc 3016. they seem like they go under the wave guides, from the bottom of the overn. so am i supposed to take off the side, and top covers, would i be able to get to it that way. how hard is it to replace these parts anyway?"
