KitchenAid KCGC500H Gas Rangetop Repair

The KCGC500H is a 30-inch commercial gas rangetop, also sold as the KCGC500HSS. A rangetop sits in the countertop with a cabinet or oven beneath, and heavy use means the igniters and caps take the most punishment.
We check each igniter and cap, test the valves at low settings, and examine the spark module if several burners fail together. On a rangetop used hard, grease and boil-overs reach the igniters and ports fastest, so we clean those before testing. Afterward we light every burner at high, medium and low, and confirm the flame holds without lifting or going out when turned down.
A gas smell means everyone leaves and the gas utility is called from outside. You get a written price first and a 30-day workmanship warranty.
Often, but a blocked port or a displaced cap can do the same. We clean and reseat first, then test the igniter and its wire.
That points to the spark module or its supply rather than a single igniter. We test the module and replace it if needed. Replacing it restores every burner at once.
Leave the house immediately and call the gas utility from outside. Do not use switches or phones inside. Do not turn on switches or use a phone inside the home. Stay outside until the utility says it is safe.
Book in about a minute, or call the desk. Same-day windows inside the Loop on most days, next-day across the rest of Houston.
