Product review (2 stars): Kitchen Aid Wall oven cannot use self clean
We had an expensive small self cleaning wall oven installed in 2008.  First time we used the self clean feature the oven failed.  Repair man of many years experience told us he has spoken with the engineers about the problem and there is no solution that allows the user to use the self clean feature. The fuse blows damaging the inner workings.  Repair man replaced some parts and the oven is usable but we are back to the old days re cleaning.  A GE model in the same location lasted with one major repair nearly 20 years.  I suspect that wall ovens are especially likely to overheat when as in our case the oven is against a brick wall.  Too bad I didn't check first because the Kitchen Aid wall oven seems particularly prone to the problems described here.
