Two oven cavities in one 30″ opening is the whole appeal of the HBLP651LUC, and it suits households that cook for gatherings and want to run two temperatures at once. Each cavity keeps its own temperature setting, yet both are managed by one control module in the middle of the unit.
That shared layout shapes how the oven ages. Wear usually appears on one side first, so you may notice the lower oven behaving while the upper one does not, or the reverse. Door locks after a self-clean, sensors and the link between the cavities and the control module are the usual suspects.
On a visit, the first thing we do is find out whether the trouble stays in one cavity. If the other oven runs normally, that narrows the search to parts belonging to that cavity. If both misbehave, we turn to the shared module.
Usually not, because heating elements and sensors are separate for each cavity. The exception is a problem with the shared control module, which can occasionally reach both cavities at once.
A sensor or door lock repair costs about the same per cavity as it would on a single oven. Replacing the shared control board is one repair that covers both cavities. You get a written price before any work.
It tells us whether to look at one cavity's parts or at the shared module, and that decides what we test first. It also helps us bring the right parts to the visit.
