During the past few days, we have received a handful of customers complaint about the same issue. After strict and repeating test checking, we have identified there is a production defect in a small minority of Sonoff TH16 and POW that were produced from Dec 2016 to Jan 2017. In order to protect the legal rights and interests of consumers, we are conducting a worldwide recall of the affected Sonoff series of produces.
What are the defects?
The Sonoff TH16 and POW are designed to work with 16A max current, which has a strict requirement on the impendences of the wires. We required the factory to add sufficient tin to the wires to ensure low enough impendences. But the word "sufficient" was not well quantized during manufacturing and QC workflow.
What are the potential hazards?
Under heavy load situation, the defect TH16 and POW get hot slowly. When the PCB is getting too hot, the enclosure may be distorted and the inner circuit may be damaged.
What should consumers do?
If you have an affected Sonoff TH16 or POW, you're entitled to require a refund or replacement. Just feel free to open a support ticket on from here and send us a photo or video of your affected Sonoff product, as well as the order number. We'll definitely provide you with a refund or replacement at your election.
