To turn on a gas furnace, ensure it’s connected to gas and electricity, then set the thermostat to “Heat” and the desired temperature. If the pilot light is out, relight it using a lighter or matches. If it doesn’t stay lit, check for gas flow, a faulty thermocouple, or a clogged pilot assembly. Troubleshoot common issues like a malfunctioning thermostat, gas valve, clogged filters, or noisy components. Always prioritize safety by using a gas leak detector, carbon monoxide detector, and protective gear. If you encounter persistent problems or suspect a gas leak, call a qualified technician immediately.
