Picture this: You’re all set for a hot shower, but your water heater’s pilot light has gone out, leaving you with nothing but cold water. Definitely not the start to your day you wanted!
That small flame plays a crucial role in keeping your hot water flowing, so when it keeps going out, it signals that something needs your attention.
Arizona’s desert climate throws curveballs: dust storms, big temperature swings, and hard water can all wear down your water heater faster than you’d expect. Understanding what’s causing the issue can help you decide whether it’s a simple fix or if it’s time to call in a professional.
Your pilot light can go out for many reasons: a faulty thermocouple, airflow issues, gas supply hiccups, or dirty parts.
Arizona’s dust and extreme temperature swings make pilot-light problems more common here than elsewhere.
A healthy pilot light burns steady blue- no flickering and no yellow flames.
You can try relighting it yourself, but if it keeps going out, it’s time to call in the pros.
Smell gas or notice repeated outages? Don’t wait! Get professional help immediately.
Think of your pilot light as the spark that ignites your water heater. It’s a small flame that stays lit all the time, ready to ignite the big burner when you need hot water. When you turn on the tap, gas flows to the burner, and the pilot light ignites instantly.
This flame also keeps a safety sensor, the thermocouple, warm. The thermocouple detects the heat and signals the gas valve to remain open. If the flame goes out, it shuts off the gas supply, preventing dangerous leaks and keeping your home safe.
Your pilot light should glow a steady blue and reach the thermocouple tip without flickering. If it doesn’t, something’s up.
Some newer heaters skip the pilot light and use electronic ignition, but most Arizona homes still rely on this trusty little flame.
Arizona’s harsh climate can cause pilot light problems to occur more frequently. Here’s the lowdown on the usual suspects:
This little sensor needs to be comfortably enveloped by the pilot light's flame to function correctly. Dust in Arizona loves to settle on it, messing with its heat-sensing.
If your pilot lights when you hold the button but dies when you let go, the thermocouple might be the culprit. Sometimes cleaning helps, but often it’s time for a replacement.
Strong desert winds and drafts can blow out your pilot light. If your water heater is in a tight spot without enough fresh air, the flame can struggle to stay lit.
Check for drafts, blocked vents, or tight spaces around your heater.
Low or inconsistent gas pressure means a weak, flickering flame that won’t keep your thermocouple warm.
If your pilot flame looks yellow or splits, or if other gas appliances are acting up, call your gas company.
When hot exhaust meets cold air, water droplets can form and drip onto the pilot light, snuffing it out. This is common in high-efficiency heaters and during chilly Arizona nights.
Dust, spider webs, or rust can clog the pilot tube or burner, starving your flame of gas and air.
Regular cleaning keeps everything flowing smoothly.
This valve controls gas flow to your pilot and burner. Heat and dust can gum it up, causing the pilot to flicker or die.
If your pilot flame weakens over time or the valve feels loose, it might need replacing, which is best left to the pros.
Older heaters wear out. Corroded tubes, mineral buildup from hard water, and worn parts all make it harder to maintain a steady flame.
Trying to relight your pilot light is okay, but if it keeps going out repeatedly, it’s best not to take chances.

How often should I check my water heater pilot light in Arizona?
You should visually inspect your water heater pilot light monthly, especially during monsoon season and winter months when pilot outages occur more frequently. Arizona’s dusty conditions and temperature extremes make regular monitoring more critical than in other climates. If you notice the pilot has gone out more than once in six months, schedule a professional inspection to identify the underlying causes.
Can Arizona’s hard water affect pilot light performance?
Yes, Arizona’s mineral-rich water accelerates buildup in pilot assemblies and gas control components. Calcium and magnesium deposits can restrict gas flow through pilot tubes and affect thermocouple operation. Hard water also accelerates the corrosion of metal components, potentially shortening the lifespan of pilot assemblies and requiring more frequent maintenance.
Is it normal for pilot lights to go out more frequently during the monsoon season?
Pilot outages do increase during Arizona’s monsoon season due to sudden pressure changes, high winds, and increased humidity. However, a properly functioning pilot light should withstand normal weather variations. If your pilot goes out every time there’s a storm, this indicates ventilation problems or component issues that need professional attention.
How much does it cost to replace a thermocouple in Arizona?
Thermocouple replacement typically costs $75-$150 for professional service in the Phoenix area, including parts and labor. The thermocouple itself costs $10-$20, but professional installation ensures proper positioning and safety testing. This relatively low-cost repair often solves persistent pilot light problems and provides years of reliable operation.
When should I consider replacing my water heater instead of repairing the pilot light?
Consider replacing your water heater if it's over 10 years old and experiencing multiple problems beyond pilot light issues, such as slow recovery, rust in hot water, or tank leaks. When repair costs approach 50% of replacement cost, or if you’re calling for service more than twice per year, replacement often provides better long-term value and improved energy efficiency.
