Homeowner decision guide
Reviewed and updated September 22, 2026
A repeatedly extinguished water-heater pilot needs qualified diagnosis rather than repeated relighting. Rheem's standing-pilot troubleshooting includes flame-sensing, pilot, gas-supply and draft or venting issues as possible causes. A failed thermocouple is therefore one possibility, not a diagnosis that follows from the symptom alone.
Identify the heater model and describe when the pilot goes out: immediately after an attempted start, during burner operation or at another time. Keep the access covers in place. A gas-water-heater repair must consider safe combustion and venting as well as the part that appears to stop the burner.
Use the sections that match what you can safely observe. They add context without diagnosing the property from a distance.
Why does a gas water-heater pilot keep going out?
If you smell gas, hear a suspected leak or have an alarm indicating danger, leave immediately. Contact emergency services and the serving gas utility from a safe place; do not operate switches, light a flame or use a phone beside the suspected leak.
Why does a gas water-heater pilot keep going out?
Stop further attempts and report exactly what happened. Ask the technician to verify the ignition and flame-safety system according to the heater's instructions. Do not hold a control down longer, defeat a safety device or buy a universal part without identification.
Why does a gas water-heater pilot keep going out?
Make the operating sequence part of the appointment request. Ask for evaluation of the gas and combustion-air or venting conditions as applicable. A replacement control should not be accepted as the complete explanation unless the findings support it.
Why does a gas water-heater pilot keep going out?
Record the coincidence but do not recreate it. Tell the technician about other fuel-burning equipment and recent building changes. Leave roof, vent and enclosed-space inspection to appropriately equipped professionals.
Why does a gas water-heater pilot keep going out?
Save the heater model and installation records.
Record the sequence before the pilot went out.
Note weather or appliance operation already observed at the time.
Report any error display, alarm or odor without returning to an unsafe area.
Why does a gas water-heater pilot keep going out?
A qualified gas-water-heater technician can evaluate ignition, controls and combustion conditions.
Emergency services and the serving gas utility handle suspected leaks or immediate danger before routine repair.
Why does a gas water-heater pilot keep going out?
What finding identifies the cause of pilot loss?
Were venting and combustion conditions considered rather than only the pilot part?
What safety and operational checks are required before return to service?

This page applies to the reported standing-pilot symptom, not every ignition design.
No gas-pressure adjustment or relighting procedure is provided.
A pilot symptom cannot establish safe combustion or diagnose an unseen heater.

Use safe, visible observations and existing records only.
