Is your furnace struggling to start, humming but not kicking on, or simply not blowing hot air? Before you panic about a costly motor replacement, the issue might be a small, inexpensive part: the furnace capacitor.
Think of a capacitor as your furnace's "jump starter." It stores energy to give the blower motor or compressor the powerful jolt they need to start spinning. When it fails, your system can't begin its cycle.
Common Signs of a Bad Furnace Capacitor:
-
Furnace not blowing hot air, but you hear a humming sound.
-
Weak airflow from vents.
-
Hard starting furnace that clicks or struggles to turn on.
-
AC compressor not starting during warmer spells (many systems share a capacitor).
-
Visible capacitor damage, like bulging, leaking, or corrosion.
A failed capacitor is a leading cause of HVAC system failure to start. The good news? Replacing it is often a quick fix.
