My boiler has no visible pilot. Is something missing?

Not necessarily. Many boilers ignite only when needed and do not have a standing pilot. Do not open the appliance to search for one. Identify the model from an accessible label or documentation and ask the provider which ignition arrangement it uses.

Can I replace a flame sensor myself?

This page does not recommend internal ignition work by homeowners. Access may expose electrical and combustion hazards, and diagnosis requires more than recognizing a part. A suitable provider should verify the fault, install the correct component if needed, and complete the required operating checks.

Why does a reset sometimes make the boiler work?

A reset can clear a recorded shutdown without removing its cause. The apparent recovery may depend on conditions that have temporarily changed. Tell the provider how often this happens and what code appears. Recurring lockouts need investigation even if heat occasionally returns.

Is this service relevant to an oil burner?

Oil burners also require ignition and flame supervision, but their fuel and control arrangements differ. Use the oil and steam service guide to describe that system. For gas equipment, include the model and sequence in Request Service; an independent provider will confirm suitability and availability.
