What should you do if you suspect a gas leak?
If you smell gas or hear a suspected gas leak, get everyone outside. Do not use electrical switches, appliances, or phones inside. From a safe place, contact the gas utility or 911. A repair service is not the first step for a suspected gas leak.
A carbon monoxide alarm also needs an immediate emergency response. Carbon monoxide has no smell; a lack of gas odor does not establish that a heater is safe. Do not stay inside to inspect a vent or try to restart the appliance.
Why does a gas water heater stop producing hot water?
Possible causes include ignition failure, a flame-sensing problem, a control fault, interrupted fuel supply, or an operating condition that triggers a safety shutdown. Not every gas model has a standing pilot. Some use electronic ignition and a display, so advice intended for an older heater may not fit your unit.
A burner that starts and then stops can leave the tank partially warm. A household that uses hot water faster than the heater recovers can produce a similar complaint. Record the pattern rather than buying a part based on the symptom alone.
What can you check without opening the heater?
From a safe, dry position, read the model label and any visible status message. Note whether every hot-water fixture is affected and whether the problem followed a power outage or other change. Look for water on the floor without reaching into the appliance or touching the vent.
Use the instructions for your exact model to understand the display. Do not follow a relighting video for a different heater. Repeated pilot failure or a recurring shutdown deserves assessment; bypassing a safety device or keeping the heater running against a fault can make the situation worse.
What does a professional assessment involve?
The technician needs to identify the appliance and establish a safe working condition first. Depending on the model and fault, assessment may include ignition controls, flame sensing, fuel delivery, combustion air, vent connections, and water-side components. The provider decides which tests and repairs are appropriate.
Ask for an explanation of the failed component and the checks that support that conclusion. Replacing a pilot component does not address an unrelated venting or supply issue. If a repair is proposed, ask how the provider will verify safe operation afterward.
When does replacement enter the discussion?
Tank condition, repeat faults, parts availability, and the suitability of the existing installation all matter. A serviceable ignition component is a different situation from a leaking tank body. You can read the repair-or-replacement guide before discussing options.
A change to another gas unit or to a different heater type requires an installation assessment. Do not assume the same size or fuel type eliminates every installation requirement. Our installation guide explains the questions to ask.
What should you have ready for a service conversation?
- Your ZIP code and whether you own or rent the property.
- The make, model, and any visible status code.
- Whether the water is cold everywhere or only at one fixture.
- When the burner problem began and whether it repeats.
- Any safely observed water leak or unusual condition.

Frequently asked questions
Should I keep relighting a pilot that goes out?
No. Repeated failure needs an explanation. Follow the exact appliance manual and stop if you suspect gas leakage, unsafe venting, or another hazard.
Do all gas water heaters have a pilot light?
No. Some use electronic ignition. Identify the model before applying pilot-light troubleshooting advice.
Can a gas heater need electricity?
Yes. Some models use powered controls, ignition, or venting. A gas supply alone does not prove that all required power is available.
Does a gas smell mean I should call a repair line first?
Leave immediately and call the gas utility or 911 from a safe place. Do not wait for a routine repair connection.
Can I replace a thermocouple myself?
This website does not provide gas-control repair instructions. Ask a qualified professional to identify the cause and follow the model requirements.
Can this website guarantee a gas repair appointment?
Call us directly to discuss your equipment and request. We confirm availability and appointments by phone. Emergency water heater service is available 24/7; a website click alone does not book a visit.
