Boiler Thermocouple Repair in Berwyn, IL

Service Pro Titans responded to a boiler service call after a client reported a pilot light issue. The pilot light would not ignite, which prevented the boiler from producing heat. Our technician arrived promptly and began a full system inspection to identify the root cause.

First, we checked the thermostat settings and verified the call for heat. Next, we inspected the gas supply and confirmed proper pressure to the unit. We then examined the ignition components, including the pilot assembly and safety controls. During testing, we identified a faulty thermocouple as the source of the problem. The thermocouple failed to detect the pilot flame, which shut off the gas supply for safety.

After explaining the issue, we received approval to proceed with the repair. Our technician carefully removed the defective thermocouple and installed a new, manufacturer-approved replacement. We secured all connections and ensured proper positioning near the pilot flame. Next, we relit the pilot and tested the boiler through a complete heating cycle.

The boiler started and operated as designed. The pilot light remained stable, and the system produced consistent heat. We monitored the unit to confirm safe and efficient performance before completing the service call.

We recommend scheduling regular boiler maintenance to prevent similar issues in the future. Routine inspections help identify worn components early and improve overall system reliability. Proper maintenance also extends equipment life and supports safe operation throughout the heating season.
