3.2 Noisy Operation
Symptom:
Noisy operation.
Cause:
The convection fan impeller was incorrectly installed, which is causing it to
rotate unevenly and therefore grate against the inner rear panel.
Remedy:
1. A bushing is now in use, as well as a spacer on the fan axle. Refer to the
parts CD for current part numbers.
2. Install the new bushing and spacer. Refer to Steps 8 and 9 in Section
035-4.5 for disassembling the fan.
3.3 Rust on Top Heat/Broil Element
Symptom:
Rust on top heat/broil element.
Cause:
Heater element was made out of an unsuitable material.
Remedy:
Install a new top heat/broil element. See Section 030-4.2.
3.4 Convection Fan Too Loud
Symptom:
Convection fan is too loud. This noise is different than an audible imbalance
(grating sound) caused by the impeller.
Cause:
The impeller is screwed crookedly onto the fan axle.
Remedy:
Replace the impeller, since the opening for the axle feed-through has been
bent. Refer to Steps 8 and 9 in Section 035-4.5 for disassembling the fan.
Note:
Fan replacement is not necessary, because the axle itself is not bent.
