97-110°C Thermostat Overheat Protector For Haier Water Heaters – V13967 0040400191 Reset Switch Temp Limiter

About This Product

This little thermostat is a direct replacement for Haier water heaters – it's the one that keeps things from getting too hot and tripping out when the temp hits between 97 and 110 degrees Celsius.

The part number is V13967 or 0040400191 depending on how you look it up.

It's got a pin width of 6mm and a hole spacing of 20mm, so make sure your setup matches before you order.

Installation is pretty straightforward – just swap out the old one if it's acting up or if your water heater keeps shutting off unexpectedly.
It works as a manual reset switch, meaning you'll have to press the button to get things going again after it trips – that's by design for safety.
Not a huge job, but definitely beats calling a plumber for something you can do yourself.

Just double-check the measurements and you're good to go.
