Repairing the Pressure Switch of a Gas Water Heater or Boiler
This isn't just a repair, but a mini-laboratory project using a grammeter, weights, and a multimeter.
In this video, I demonstrate why the switch can't be replaced, how it works, how to clean it, and its technical documentation and complete repair manual.
If there were a test bench for such devices, I would show how to configure it, but I've described it briefly and clearly, explaining the process.
