Directions for System Diagnosis Flow Chart
A test set-up is described at the beginning of each test sequence. Directly below the test set-up is a description of
the normal oven operation(s) (identified by a question mark).
If oven operation is normal, follow the YES sequence down the left side of the page.
If oven operation is abnormal, follow the NO sequence to the right side of the page.
To effectively use this flow chart, the directions below must be followed:
• Always start at test sequence 1, perform each test set-up, do not skip test sequences.
• Verify normal operation(s) following each test set-up before going on to the next test sequence or set-up.
• When abnormal operation is identified, disconnect power to the oven, DISCHARGE CAPACITOR(S), determine
cause starting with the first possible cause, correct the failure, then start over at test sequence one to verify
normal operation.
NOTE: Always check for failed or improper wiring before servicing.
