Pilot Light and Ignition Repair in Saint Louis, MO

Older boilers run a standing pilot with a thermocouple, which makes the small voltage the gas valve needs to stay open. A pilot that lights and then goes out when you let go of the knob is usually a weak thermocouple.

Newer boilers use a hot surface igniter or spark ignition, followed by a flame sensor that proves the burner lit. A sensor coated in oxide reads too low and the control shuts the gas off after a few seconds. You see the burner light, then die, then try again until the boiler locks out.

Reliable Boiler Service connects Saint Louis, MO homeowners with technicians who test these parts with a meter rather than swapping them at random: thermocouple millivolts, flame signal microamps, igniter resistance, gas pressure at the valve.

Smell gas? Leave the house and call your gas utility from outside first.

Pilot Light And Ignition Repair FAQs

Frequently asked questions about Pilot Light and Ignition Repair

Questions we hear most often about Pilot Light and Ignition Repair in Saint Louis, MO.

Talk to a real person
Why is the relief valve on my boiler dripping?
A relief valve that drips or opens near 30 psi usually means a waterlogged expansion tank or a fill valve letting too much water in. Replacing the valve alone rarely fixes it.
Is a combi boiler a good fit for my home in Saint Louis, MO?
A combi suits homes with one or two bathrooms and a gas line big enough for its hot water demand. Larger households often do better with a heat-only boiler and an indirect tank.
Why does my steam heat bang and hammer?
Banging usually comes from condensate trapped in a pipe that lost its pitch or a radiator tilted the wrong way. A pressuretrol set too high makes it worse.
Are there rebates for high-efficiency boilers?
Many gas utilities and state energy programs offer rebates on qualifying condensing boilers. Terms change often, so check your utility's current program before you buy.
How do I know if my boiler is the right size?
A room-by-room heat loss calculation is the only real answer. Boilers that short cycle on mild days are often oversized for the house.
