Top Reasons for Sprinkler Controller & Timer Issues

Local environmental factors and seasonal cycles play a massive role in the health of your property. Here are the most common triggers we see right now.

Common Technical Causes

Voltage Output

Terminals should show 24VAC-28VAC when a zone is active.

Transformer Health

Input voltage must be a steady 120V; anything less will cause "ghost" reboots.

Memory Retention

Failed backup batteries result in lost programs during brief power blips.

What To Do Next

Choose your path to a healthier property. Try these simple diagnostic steps yourself, or skip the hassle and call a verified pro.

Quick Checks You Can Do

Before calling anyone, try these zero-cost steps to see if it's a simple fix.

1

Restart the controller by unplugging it for 60 seconds

2

Check the rain sensor to ensure it isn't stuck in "off" mode

3

Inspect the wire terminals for loose or corroded connections

4

Test for 120V power at the outlet using a different device

When to Call a Specialist

If you notice any of these signs, the problem will likely spread without professional repair.

Power surges from lightning or grid fluctuation
Blown internal fuses or tripped circuit breakers
Dead CMOS/Backup batteries in older units
Wi-Fi interference or outdated firmware in smart controllers
