JennAir G102 Gas Cartridge Cooktop Repair and Service
The G102 is a 30-inch gas drop-in with swappable burner cartridges and a self-ventilated downdraft. It is the gas partner of the electric cartridge cooktops, so you find it set into the same kind of counter cutout, usually with the duct running to an outside wall.
On a gas cartridge cooktop the burner and the vent are unrelated, and almost every call is one or the other. A burner that clicks but does not catch points to a dirty igniter or clogged ports; a flame that burns unevenly points to buildup on the ports. A sluggish vent points to a clogged grease trap or a tired blower.
If you smell gas at any point, leave the house and call the gas utility from outside. We check the ignition and ports first, then the flame, then the downdraft. You receive a written price before any work, and the repair carries a 30-day workmanship warranty.
Yes, each burner cartridge is treated as its own module. We test the igniter, clean the ports and check the gas path to it, then quote any part separately before starting.
Residue on the igniter or ports weakens the spark and slows ignition. We clean both, then test the spark. A worn igniter or spark module is replaced only if cleaning does not fix it.
No, the vent runs on electric power, apart from the gas. We check the grease trap, duct and blower motor. A gas smell is a different matter, and means leave and call the utility.
