Hardie HR62000 Blowing 2-Amp Fuses

Hardie HR62000 timer repeatedly blows 2-amp fuses.

First Step: Clean Circuit Board

Dust, spiders, or insects on the board can create conductive paths causing shorts. Use canned air (electronics duster) to thoroughly clean the board—both sides if accessible.

If Cleaning Fails

Short in field wiring (valve solenoid or wire).
Failed component on controller board.
Disconnect field wires one zone at a time to isolate.

Provide more details (when it blows, which zones active) for deeper diagnosis.
