Utica-Dunkirk 28687 Flame Sensor
The Utica-Dunkirk 28687 Flame Sensor is a critical safety component engineered for precise flame rectification in high-efficiency residential and commercial gas-fired boilers and furnaces. Designed for compatibility with various Utica and Dunkirk heating systems, this OEM replacement flame sensor monitors the burner assembly's combustion process by converting AC voltage into a measurable DC microamp signal. A veteran tech knows that a reliable signal—typically between 1.5 and 10 microamps—is essential for the ignition control board to maintain the gas valve’s open position. Constructed with high-grade stainless steel and a durable ceramic insulator, the 28687 prevents common system failures such as short-cycling and safety lockouts caused by carbon buildup or cracked porcelain. When troubleshooting an HVAC flame sensor, ensuring a clean ground connection is as vital as the probe's alignment within the flame. Replacing a fouled or degraded sensor with this authentic Utica-Dunkirk part ensures optimal equipment longevity and consistent heating performance under high-temperature operating conditions.
Key Benefits:
- Precise Flame Detection: Accurately monitors flame ionization to ensure safe gas valve operation and prevent unburned gas release.
- OEM Compatibility: Designed specifically for Utica and Dunkirk heating systems, ensuring a perfect fit and consistent voltage response.
- Heavy-Duty Construction: Features a robust stainless steel rod and high-temp ceramic insulation to withstand harsh combustion environments.
- Reduced System Downtime: Eliminates intermittent ignition failures and furnace lockouts associated with aged or oxidized sensors.
Common Questions:
- How do I test the Utica-Dunkirk 28687 for failure? Use a multimeter set to microamps (µA) in series with the sensor wire. A reading below 1.0 µA usually indicates a dirty or failing rod.
- Can I clean the 28687 flame sensor instead of replacing it? While light oxidation can be removed with a non-abrasive material, any cracks in the porcelain or significant pitting on the rod require an immediate replacement to ensure system safety.
- Why is my furnace shutting off after only a few seconds of flame? This is a classic symptom of a dirty flame sensor or a poor ground. If the board doesn't receive the rectification signal within the timing window, it will kill the power to the gas valve.
