Pilot Light Diagnostics & Safety Guide
Diagnose common flame failures, understand mechanical root causes, and follow critical gas safety protocols before requesting on-site technician service.
If you smell gas (rotten eggs/sulfur), hear a hissing pipe, or suspect a gas buildup, do not attempt to light the pilot. Evacuate everyone from the home immediately and call local emergency services or Riverdale gas utility lines from outside.
Fouled or bent thermocouple, loose gas valve connection, or weak gas supply.
Air shutter blockage, lint/dirt in the pilot orifice, or incorrect fuel mixture.
Worn spark igniter electrode, moisture on contacts, or faulty control module.
Downdrafts from unsealed vents, tripping thermal cutoff switch, or failing gas valve.

Diagnostic Checkpoints
Follow these essential checks before scheduling repair.
Verify that the main gas shutoff valve to your water heater is fully open and parallel to the gas line.
A loose, dirty, or bent thermocouple sensor prevents the pilot from registering heat and shuts off gas flow.
Carbon deposits, lint, or insect debris can choke the tiny orifice, leading to a weak, flickering yellow flame.
Electronic or newer gas systems use millivolt thermopiles. If voltage output drops below spec, the valve resets.
