Replace Pilot Light On Gas Fireplace. Typically it is a spider. My husband replaced the thermonucouple and the gas valve we can light the pilot and it will fire but as soon as its satisfied and turns off the pilot light goes off can you please give me some input.

Pilot light systems are the most common reason gas fireplaces fail to light, according to justin worthen, outside coordinator of alpine fireplaces.

Please remove all fireplace glass before igniting your pilot light. Propane gas fireplaces burn fuel supplied by propane tanks. They use a safety pilot control valve to start or ignite a pilot light. The pilot light in my fireplace is working but when i turn the switch on (new switch) it wouldn't fire up.
