• TOP QUALITY REPLACEMENT: Our Furnace Flame Sensor is made of high-quality, wear-resistant metal and ceramics. The manufacturer has rigorously tested all the materials and redesigned them to improve durability and stability. It ensures durability and resilience against temperature changes, maintaining consistent performance.
• EASY TO INSTALL: Installing a new Furnace Flame Sensor is simple for any DIY handyman. Remember to shut off your furnace before making any repairs and wear work gloves to protect your hands. Then, find the sensor - it’s typically mounted by a 1/4” hex head screw. Carefully remove the screw and the sensor will slide out. Finally, replace the faulty sensor with a new one, turn the power back on, and check your result.
