A gas regulator for a cooktop decreases or increases the pressure of gas in a line before it reaches the cooktop. A regulator has three components that are used to reduce or increase pressure. When the regulator knob is turned to decrease pressure, it compresses a spring, which serves as the loading mechanism. The sensing element and control element sense this pressure and adjust the pressure of the gas flowing through the line. If the gas regulator on the cooktop is not functioning properly, the pressure buildup can result in a gas leak.
Turn off the gas shutoff valve near the cooktop by turning it clockwise.
Take off the cap on the regulator by removing the screw on top with a screwdriver. The gas regulator is generally located beneath the cooktop near the gas inlet.
Press the “On/Off” button on a manometer to turn it on. Check the display to ensure the current reading is “0.” If the reading is not “0,” pull off the two hoses and press the “Zero/Store” button.
Connect the hose on the positive line on the manometer to the regulator inlet located beneath the removed cap. Turn the gas shutoff valve counterclockwise to turn the gas on, and check the display on the manometer. A reading of “0” indicates that the gas cooktop regulator is not functioning properly and requires replacement. If a number is displayed, the regulator is working correctly.
Turn the shutoff valve on the gas line clockwise to turn the gas off, and remove the hose on the manometer. Place the cap on the regulator, replace the screw and tighten it to secure the cap. Turn the shutoff valve on the gas line counterclockwise to turn on the gas.
