Burner Won't Ignite — FAQs

Why won't my water heater burner ignite?

When the burner won't fire, you lose hot water entirely. Causes range from a tripped thermal switch and blocked combustion air to a failed igniter or gas valve. We diagnose the ignition system and get the flame back safely.

Can I fix this myself?

Some basic checks (like resetting a breaker) are safe, but most water heater repairs involve gas, electricity, or water under pressure and should be handled by a licensed pro for safety and code compliance.

How much will the repair cost?

It depends on the part and labor involved. We provide a flat, upfront price after diagnosis—and free estimates.

Should I repair or replace?

If your unit is under 8–10 years old, repair usually makes sense. If it's older or the tank itself is failing, replacement may be smarter. We give honest advice.
