What you are describing is almost always a power supply failure.
- If you have a power supply where the prongs slide out, check to make sure that it is seated properly. Slide it out and make sure there is no water or debris in between the contacts.
If there is water, it is likely that the source could be from the outlet. Sometimes the hole where the wires come through on the back of the outlet box can be a point where warm, moisture laden air sneaks in. Take off the outlet cover to check and if there is moisture in there, dry it out and then put silicone around where the wires come in in the back.
If your power supply has a blue light, you could open it up and see if it is wet and dry it off (you don't need to do ANYTHING with the CoolBot). Even if works, you should proceed with the next 2 steps:
- You can buy a replacement power supply from us online at www.storeitcold.com/techsupport (lower right hand side of the page). The new power supplies we have are outstanding. Way more waterproof
- You can buy something locally at Radio Shack or Best Buy or WalMart (any store with an electronics department) or you can use a phone charger for an android smartphone that's newer and then you just buy a cable with a mini USB plug.
Our CoolBot runs on a standard MINI-USB phone charger (MINI, not micro or lightning) All Mini-USB power supplies (all USB power supplies of ANY type) put out 5 volts, so that's easy but some only put out a small number of amps. The CoolBot runs on 1 Amp (or 1000 mA or milliamps... same thing). You can have more than that, but you can't have less... so something that says "350 mA" won't work... something that says "2.1 Amps" would work fine! [like the Samsung Galaxy chargers]
Check the outlet and try plugging the CoolBot into a different outlet. Be sure your circuit breaker is on.
