JennAir JIC4730H Lustre Flex Induction Cooktop – 30-Inch Service
Thirty inches of Lustre induction with flex zones, the JIC4730H, also sold as the JIC4730HB and JIC4730HS, fits the standard cooktop cutout and handles pots of different sizes. In black with stainless trim, it is part of the Oblivion / Lustre family and usually sits above a base cabinet or a drawer stack.
This kind of cooktop depends on its cooling system. We start by checking that the unit gets stable power and that the fan spins freely and the vents under the cabinet are clear. Then each zone is tested with a flat magnetic pan, and the flex area gets a check of coils and sensors.
We quote the price in writing before beginning, and you get a 30-day workmanship warranty on the finished repair.
Usually that the cooktop is protecting itself from heat. We look at airflow, the fan and sensors. Packed storage underneath is a frequent contributor. A dusty fan is one of the first things we clean.
The glass is strong but can chip if hit or if a heavy pot is dropped. Hairline cracks should be looked at right away, since liquid can reach the electronics.
Light humming can come from the pan base vibrating in the magnetic field, especially at high power. Constant loud noise is different and may mean a fan problem.
