Key takeaways
- Check the outlet, timer and photocell first
- Walk the run and check connections
- Look for recent digging that may have cut wire
- Call a professional for damage or anything on line voltage
Start at the power
Check that the transformer has power: look at the outlet, the GFCI and any breaker. Make sure the timer or photocell is set correctly and that the photocell is not covered or shaded. Many outages are simply a tripped outlet or a timer that lost its time.
Switch the transformer to manual on to see whether the lights come on.
Walk the run
If one zone is out, follow the wire from the transformer. Look for recent digging, edging or aeration that may have cut the cable. Check connections at the first few fixtures, because corroded or loose connectors are common.
If only one fixture is out, try a new lamp, then check its connection.
Know when to call
If you find damaged wire, water inside fixtures, burned connectors or a transformer that hums or smells hot, turn the system off and call a professional. Line-voltage wiring should only be handled by an electrician.
A technician with a meter finds faults far faster than swapping parts.

Quick answers
Why did my whole zone go out at once?
Usually a break in the main run, a bad connection near the transformer or a tripped breaker. Following the wire from the transformer finds it.
Is it safe to work on low-voltage lighting?
Low-voltage wiring is safer than line voltage, but the transformer plugs into line voltage. Always switch off power before handling connections, and call an electrician for anything on the line side.
