Vent tube in the roof of this self-cleaning wall oven has dropped its ceramic catalyst. The vent tube, Whirlpool pn 3186684, is no longer available. We do not use the self-clean feature. Is it safe to use the oven without the ceramic catalyst?

Thanks.

Here is your part.

If oven is very dirty I would wipe it out first just to reduce the smoke creation.

Got it, thank you.
