Troubleshooting The Gas Valve
To determine the cause of your furnace malfunction, check the gas valve to see if your furnace has stopped producing heat or has shut down. Here are some steps you can take to determine if you have a faulty gas valve:
Check if the motor is running.
Check all the wires leading to the gas valve. They need to be replaced if broken, frayed, or burnt. Wires are usually damaged in older furnaces.
Check the resistance of the coil at the gas valve using a multimeter. If the reading shows OL, then it means the coil is broken.
Check if the gas valve is correctly adjusted according to your furnace. At times, the technician performing the installation leaves the valve at the default setting, which can cause the ignition chamber to receive too much or too little gas, causing your system to malfunction.
Check the burners and make sure that they are not clogged.
Check if the flame sensors are working correctly.
Using a multimeter, check if the pressure drops across the inlet and outlet.
Check the evaporator coil and the blower motor. The system will shut down if they do not work correctly due to a safe trip.
Inspect the ductwork thoroughly and ensure it is not clogged, especially the return duct.
Although all the above components work correctly, a faulty gas valve may still be the issue. Replacing the gas valve on your own is possible but not recommended, as it could result in unintentional harm to the furnace or yourself. If the gas valve is defective, it is best to seek assistance from a reliable professional for heating replacement in Houston, TX.
