Pilot Light and Ignition Repair in Forestburgh, NY
A weak thermocouple fails to keep the gas valve open after the pilot flame is lit. Melvin's Water Heater Service measures millivolt output from the thermocouple under flame. Readings below thirty millivolts require replacement. Technicians clean the pilot orifice of spider webs that restrict gas flow. One paragraph describes the piezo igniter button and its spark gap.
After reassembly the flame sensor is positioned in the hottest part of the pilot. Call (833) 774-1697.
