Gas Water Heater Repair for Snellville area homes

When a gas water heater stops making hot water, the cause is often a small part in the burner assembly. A pilot that will not stay lit, a burner that lights weakly, or a control that does not respond can all leave you with cold water.

Gas water heater repair in Snellville focuses on those components while keeping safety at the center. Gas appliances need correct combustion and venting, so a repair always includes checking that exhaust is leaving the home as it should.

Common gas heater problems

Pilot will not stay lit

A worn thermocouple or flame sensor is a frequent cause on standard gas tanks.

Weak or yellow flame

Dirt, lint or a restricted air intake can affect the burner. A yellow flame should be checked promptly.

Gas smell near the heater

Leave the area and contact your gas utility from a safe place before anything else.

Not enough hot water

Thermostat settings, a broken dip tube or sediment can all reduce supply.

When a gas repair stops making sense

A failed gas control on an older tank can cost enough to make replacement worth considering, especially if there is visible rust in the combustion chamber or at the base.

If the tank is past ten years or shows corrosion, the gas water heater replacement page describes what a full replacement involves, including venting and gas connection checks.
