None Water Heater: not getting gas

Professional Repair Guide

What is this symptom?

Is your gas water heater not receiving gas, causing ignition failures and lack of hot water? This issue can stem from a gas supply interruption, blockages in the gas line, or triggered safety shutoffs. Identifying the cause is crucial for restoring hot water efficiently.

Urgency: High

Possible Causes

Gas supply interruption or shutdown

How to Identify: No gas flow to unit; gas meter safety shutoff engaged (e.g., after earthquake; gas inlet valve closed; other gas appliances also not working.

Part: Gas supply line / gas meter / shutoff valves

Blockage or restriction in gas line

How to Identify: Gas reaches meter but not heater; sluggish burner ignition; technician-required pressure test.

Part: Gas line / gas valve

Thermal or safety shutoff triggered

How to Identify: Gas flow stops after overheating or prolonged operation; reset needed.

Part: Thermal switch / safety cutoff / gas valve safety mechanism
