If your Goodtimer won’t light up and/or is making a loud, repetitive, chiming noise when you plug it in to charge, it typically is not getting enough power through the ac adapter to actually charge the device. Each Goodtimer comes with a UL certified AC adapter that requires a certain amount of electrical flow to be able to safely and effectively charge the Goodtimer’s battery. If the adapter is plugged into a power strip or surge protector and this is happening, please try plugging the adapter directly into the wall outlet and see if that corrects the issue. If it does, then the power strip is restricting the flow enough that Goodtimer is not able to recharge.
Under normal circumstances, a little LED by the charging port on your Goodtimer will light up red when the battery is getting low. When you plug it in, a charging chime will sound and the little LED will turn green to indicate it is charging. Once charging is complete, the LED will turn off.
But sometimes, if your Goodtimer’s battery has drained completely, it may chime over and over when plugged back in until it has gotten enough power to fully start up. If you are able to adjust the volume down to silence the chime, leave it plugged in until the LED goes out. Then we recommend resetting it, by holding down the Reset button on the bottom of the device for a full five seconds, to make sure that the device and software are properly restarted.
