September 11, 2026 — A Makevivi thermostatic switch, intended for residential exhaust fans, has been identified with multiple severe wiring and design flaws that present a significant risk of electric shock and fire. A competent electrician discovered an open ground, reversed hot and neutral wires, and a relay that switches the neutral line instead of the hot, making the product’s outlet continuously live and disabling crucial safety mechanisms.
Product Details
Product: Makevivi none shown
Incident Overview
On August 20, 2026, an individual preparing to install a Makevivi thermostatic switch for a residential exhaust fan performed a routine pre-installation safety check. Using a plug-in GFCI tester (Intertek 3080912), the installer immediately identified an open ground at the product’s outlet.
Being an experienced electrician, the individual proceeded to open the device to repair the detected fault. Upon internal examination, several deeply concerning design and wiring errors were uncovered. Firstly, the hot and neutral wires were found to be reversed at the product’s outlet. Even more critically, the internal relay—designed to control the power flow—was switching the neutral wire instead of the hot wire. This fundamental wiring error means that the “neutral” side of the product’s receptacle remains continuously hot, regardless of the relay’s state.
This sequence of flaws effectively renders the device extremely dangerous and negates standard electrical safety protocols.
Safety Concerns
The identified defects in the Makevivi thermostatic switch pose immediate and severe safety risks:
- Immediate Dangers: Severe Electric Shock and Electrocution Hazard: Because the “neutral” of the receptacle is continuously hot, any user mistakenly believing the power is off (due to the relay being open) could be exposed to live current. Furthermore, any ground fault in a device plugged into this switch will not trip a standard circuit breaker or GFCI as intended. Instead, the frame of the connected device and any metal it contacts will become electrically live, presenting a direct and potent shock hazard, potentially leading to electrocution.
- Fire Hazard: The uncontrolled flow of electricity through unintended paths, especially in the event of a ground fault that does not trip protective devices, can generate excessive heat. This uncontrolled heat can ignite nearby flammable materials, leading to electrical fires within the home.
- Compromised Electrical Safety Systems: The product’s design undermines the fundamental principles of electrical safety. It defeats the protective function of safety grounds and prevents overcurrent protection devices (like breakers and GFCIs) from operating correctly, leaving users and property vulnerable to electrical mishaps.
- Who Might Be Affected: Anyone who has purchased or installed this Makevivi thermostatic switch, as well as anyone using an appliance or exhaust fan plugged into or wired through this device, is at risk. Occupants of residential properties where these switches are installed are particularly vulnerable.
- Property Damage Potential: The fire hazard created by the faulty wiring could lead to extensive property damage, beyond personal injury.
What Consumers Should Do
If you own a Makevivi thermostatic switch, take the following immediate actions:
- Immediately Cease Use: Unplug any devices connected to this switch and, if possible, safely disconnect the switch from your home’s electrical system by turning off the corresponding circuit breaker.
- Do Not Attempt to Repair: Given the complexity and severity of the wiring defects, do not attempt to repair the product yourself unless you are a qualified and licensed electrician. Even then, repair is not recommended due to inherent design flaws.
- Identify the Product: Check if your thermostatic switch is a Makevivi brand. If there is any doubt, or if you have a similar, unbranded thermostatic switch from Amazon.com, exercise extreme caution.
- Contact a Qualified Electrician: If the device is already installed, contact a licensed electrician to safely remove the product and inspect your wiring for any potential impacts.
- Report the Incident: If you own this product, report your experience to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Providing details helps authorities monitor product safety and initiate potential recalls.
