Gas Appliance Not Working service helps identify why a furnace, water heater, range, dryer, fireplace, or boiler will not ignite, stay lit, or heat correctly. Seattle Plumbers checks the fuel supply and customer-owned gas connections, repairs confirmed piping defects, and directs appliance-specific work to the proper qualified technician when needed.
Check for an Immediate Gas Hazard
Check for an immediate gas hazard before treating the problem as a routine appliance failure. If you smell sulfur-like gas or hear hissing near the appliance, leave the building without using switches, phones, flames, or anything that could create a spark. Call Puget Sound Energy or 911 from a safe location.
Do not repeatedly try to ignite an appliance when gas may be present. Wait for the gas utility or emergency responders to declare the site safe.
How the Appliance Failure Appears
Appliance failure may appear as no ignition, delayed ignition, weak flame, repeated shutdown, an error code, or no heat. Note whether one appliance is affected or every gas appliance has stopped working. Also note any recent outage, gas shutoff, remodel, appliance installation, or movement of the equipment.
Common service calls involve:
- A gas water heater that does not heat
- A furnace or boiler that starts and then shuts down
- A range burner that will not light correctly
- A gas dryer that runs without heating
- A fireplace that does not ignite or stay lit
Gas Supply and Connection Inspection
Gas supply and connection inspection separates a piping problem from an internal appliance fault. We inspect the accessible gas line, shutoff valve, flexible connector, appliance regulator, and connection condition. When appropriate, we measure supply pressure with a manometer and assess whether the pipe can carry the required BTU load.
The burner, igniter, pilot assembly, thermocouple, flame sensor, vent, power supply, or electronic controls may also affect operation. We explain whether the confirmed issue falls within plumbing and gas-piping service or requires an appliance technician trained for that equipment.
Gas Appliance Connection Repair
Gas appliance connection repair may include replacing a damaged connector, repairing a leaking joint, installing a working shutoff valve, correcting an undersized gas line, or supporting and sealing customer-owned piping. We use approved components suited to the fuel type, appliance input rating, and installation.
After gas-piping work, Seattle Plumbers tests the completed connection and verifies safe fuel delivery. Appliance relighting or startup follows the manufacturer's procedure and the limits of the authorized service scope.
Schedule Gas Appliance Diagnosis in Seattle
Schedule gas appliance diagnosis in Seattle when equipment stops operating and there is no active leak emergency. Tell us which appliance is affected, how it behaves, and whether other gas equipment still works. Those details help us bring the right diagnostic approach and provide a clear next step.
