JennAir JGD3536BS Gas Downdraft Service for the JX3 Cooktop

The JGD3536BS spreads five sealed burners across 36 inches and adds a downdraft, with a 17,000 BTU ultra-high output burner as its top flame. As a JX3 model, it typically serves in an island setup, where the room is open and exhaust has to leave through the floor of the cabinet instead of a hood.
More burners and a longer downdraft slot mean more places for grease to settle. During a visit, we look at the burner caps and ports, then pull out the filter and examine the blower wheel. If the draw is weak even after cleaning, the duct and the blower motor are next in line.
Gas odor means you should leave the house and call the gas utility from outside. We give a written price before we start, and repairs are covered by a 30-day workmanship warranty.
No. Use the low speed for gentle cooking and high for searing or boiling. Running at a speed that matches the burners keeps the blower from wearing out sooner.
It should sit flat without rocking, centered on the burner base. A crooked cap produces an uneven flame and sometimes poor lighting. Lift and reseat it, then test.
Heavy grease buildup in any vent is undesirable. Keeping the filter clean and having the duct checked when airflow drops are sensible steps, and we can inspect it during a visit.
