JennAir JGRP548H NOIR Griddle Range repair, 48-inch
The JGRP548H is a 48-inch NOIR gas professional range with six burners and a griddle, and its sibling numbers are JGRP548HL and JGRP548HM. At that width it is typically installed in a large kitchen with a dedicated hood and gas line sized for it.
With six burners and a griddle, there are more places for heat and grease to cause trouble. We test each igniter, clean the ports where spillover has hardened, and then run the griddle to see whether the heat is even across the plate. The oven gets its own check: ignition, sensor and door seal. Any gas odor means leaving the home and calling the gas utility from outside. We quote the price in writing before beginning, and the repair has a 30-day workmanship warranty.
Uneven griddle heat points to a partly clogged burner under the plate or a failing valve. We clean the burner, check the flame pattern and test the valve before recommending any replacement.
No. Each burner has its own igniter and port, so we diagnose the one that fails. If several fail together, we look at the spark module that feeds them.
Usually yes, since the oven has its own ignition. If any burner or the oven smells of gas, stop and leave the house first. We service the range after the utility has cleared it.
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.
