JennAir JGD8348CDP Modular 48-inch Downdraft Rangetop Repair

The JGD8348CDP is a 48-inch Pro-Style gas rangetop assembled from separate modules. A pair of two-burner modules and a grill assembly sit side by side, and a single downdraft vent in the middle draws smoke away from every one of them, so the unit works well in an island where no hood can hang.
Since the modules depend on common venting and control wiring, our first job is to learn whether the trouble belongs to one module or to something they all use. We light each pair of burners alone, bring the grill assembly up to heat, then trace the downdraft path from filter to blower. When one module stops responding while the others run, we follow its connection back to the control. You get a written price before any part is ordered, and the repair carries a 30-day workmanship warranty.
Generally no. The grill assembly has its own heating and ignition parts, so we test it by itself first. The burner modules are only opened if they misbehave too.
Yes, the one blower and duct serve the whole rangetop, so weak pull is felt at every module. The burners and grill still heat independently, but we advise fixing the blower so smoke clears.
That points to the connection or control path serving that single module. We check the wiring and connector, test the module's control part, and quote the repair before we start.
