What does W mean on a fuse?
Type W: These fuses react fast to the amperage if it exceeds the rating. These fuses ae used for general purpose circuits and lights. They are not recommended for circuits with motors.
What does it mean when fuse is open?
A fuse is essentially a short piece of wire of a selected diameter and composition so that it conducts current up to a certain level, but melts or ‘fuses’ if the current rises above that level. It becomes an open circuit when it blows, interrupting the flow of current and preventing damage.

Why does the fuse keep blowing in my air handler?

Breakers and fuses are designed to trip or blow when too much voltage is sent through the line.
Why does my fuse keep blowing in my furnace?
Short Circuits, Wiring One likely culprit for a furnace blowing a lot of fuses is because of damaged wiring, or because of a short circuit.
