Fault Codes[...]

11 The NGC (Tornado) oven has the ability to continually monitor and log various fault conditions. Some fault conditions will terminate cook cycles, while others will not. Please refer to the fault code table on page 12 for more detailed information. When a fault is detected, the Fault Log will incre- ment. However, if the fault is subsequently cle[...]

FAULT CODES 12 NOTE : Door interlock switches are in parallel. See OVEN SCHEMATICS , pages 55-63. The fault is moni- tored during a cook cycle, or in SELF TEST when the microwave is on. F5: Magnetron Over Temperature Fault is displayed when either magnetron thermo- stat is “open.” The fault is cleared from the display at the onset of a cook cyc[...]
