KitchenAid KEBC278K Oven Service

The KEBC278K is a 27-inch double electric wall oven with True Convection in both the upper and lower ovens, sold in stainless as the KEBC278KSS. That is two convection fans, two sensors and two sets of elements behind one control, so a repair visit starts with identifying which cavity is acting up.
The self-clean cycle is the hardest test for this oven. It runs hot enough that a door lock motor can stick, and an oven that stays latched afterward is usually a lock problem and not a broken door. Fans are the other wear point, since convection baking keeps them spinning for long periods.
We confirm the issue in the affected cavity only, then test the fan, element and sensor in order. A written price comes first, and a 30-day workmanship warranty covers the repair.
Possibly. Both ovens have True Convection, so we listen for the lower fan and check that the blades turn freely. If the fan spins, the sensor or the element may be the cause.
Please do not force it. The lock motor or its switch may be stuck, and pulling can bend the latch. We free the mechanism and test the lock so it releases normally.
The parts differ in size, but the service steps are the same. We can usually reach the fans, sensors and elements without moving the unit, which keeps the visit short.
