What Causes Pilot Light Keeps Going Out
A pilot light that repeatedly extinguishes is usually caused by a faulty thermocouple (the safety sensor that detects the flame), a dirty pilot orifice, drafts near the water heater, or a failing gas control valve. The thermocouple is the culprit in roughly 80% of cases.
Boise-specific factor: Boise's windy conditions — especially during spring Chinook winds and fall storms — can create drafts in garages and utility rooms that blow out pilot lights. Homes in the Boise Foothills and exposed areas of Eagle are particularly affected.
Signs You Have Pilot Light Keeps Going Out
Watch for these warning signs in your home:
- ✓ Pilot light goes out repeatedly within hours or days of relighting
- ✓ You can see the pilot flame but it's weak or yellow instead of blue
- ✓ Gas smell near the water heater when pilot is out
- ✓ Water heater won't stay lit even after holding the pilot button for 60 seconds
Can You Fix This Yourself?
Try relighting the pilot following the instructions on the water heater label. Hold the pilot button for a full 60 seconds before releasing. If it goes out again within 24 hours, the thermocouple likely needs replacement — this is a professional repair due to gas line safety.
If the problem persists or you're unsure, call a licensed plumber. Attempting complex repairs without proper tools can cause further damage and void warranties.
