Persistent 'NO AC' on Hunter XC: Transformer Voltage and Wiring Checks

Hunter XC Shows "NO AC"; New Unit Lasted 2 Days

Changing the breaker from 15 A to 20 A won’t help. Measure the transformer output at the controller’s 24 VAC terminals—should be 23–26 VAC.

Replace with an Irritrol Rain Dial or Rain Bird ESP for better reliability.
