Teardown And Repair Of A Insoma Water Timer

A water timer with three solenoid-controlled outlets stopped working entirely, prompting a teardown rather than a warranty claim. Testing showed the solenoids, rated for 6VDC, worked fine on battery power, but the control board only output about 2V, insufficient to trigger them. After scraping through potting compound, the culprit turned out to be a failed electrolytic capacitor in the power boost circuit, leaking near its base after just four months of use. Replacing the capacitor fixed the device.
