Without a functioning electrode, the furnace would be unable to produce heat, leaving the system idle and cold. They also check and adjust the electrode gap to the manufacturer's specifications.
Essential Maintenance Practices for Oil Furnace Electrodes
The body is usually made of ceramic, which acts as an insulator to prevent the electrical current from escaping into the furnace housing. Because of the inherent dangers and the complexity of modern furnace controls, electrode replacement and diagnosis should be performed by qualified HVAC professionals.
Common Failure Symptoms and Diagnosis When an electrode begins to fail, homeowners might notice specific warning signs. The tip features a specific configuration, often featuring a needle-like point or a specific geometry, to focus the electrical field and facilitate the spark jump.
