    Microwave System The i5 oven employs two independent microwave systems (left and right). In the case of an over- current situation relative to the left system, the F3 fuse will blow. In the case of an over-current situation relative to the right system, the F4 fuse will blow.
  • Page 46 OVEN SYSTEMS NOTE: The terminals with the orange dot or the orange wire always go to Terminal 3 on US models. To verify correct wiring (International), measure the voltage between the taps on FT1 and FT2. The voltage must be 220 VAC (Latin America), 200 VAC (Japan), or 230 VAC (International).
