Cleaning a Furnace Flame Sensor | DIY Repair Clinic

Nothing’s worse than your furnace going out in the middle of fall and winter. Most problems aren’t catastrophic—many are easy to fix or prevent with simple maintenance. Here are the top 5 culprits: 1️⃣ Dirty Flame Sensor – Stops your furnace from running safely if coated in dust or soot. Cleaning it often restores normal function. 2️⃣ Worn Igniter – Turns on your furnace every time. Over time, heat and power surges can cause failure. 3️⃣ Inducer Motor Issues – Draws air through your system. Bloc
