Hunter XC Controller No Display After Power Outage: Reset and Power Checks

A Hunter XC with no display after a power outage—breaker reset didn't help—usually just needs a controller reset or has a power supply issue.

Step-by-Step

1. Press the reset button in the lower wiring compartment (small recessed button). Hold 5 seconds.
2. Verify 110VAC at controller: Use multimeter on the line voltage wires (black/white) inside the cabinet. No power = tripped GFCI, bad breaker, or damaged transformer.
3. Check transformer output: If 110VAC is present, measure 24VAC at the two yellow transformer wires. No 24V = bad transformer (replace, ~$20).
4. Still no display? Controller main board failed. Hunter XC is under warranty for 1 year—contact Hunter for replacement.

Common Cause

Power surges during grid restoration often damage the controller's input protection. A surge protector on the 110V supply (or a whole-house suppressor) prevents this.

Start with the reset button—it fixes 50% of post-outage blank displays.
