I have a simple coffee machine that has a little "controller" that control the ON/OFF of the heater. Suddenly, the machine stop heating the water (and the recipient). I have open the base and test with a continuity tester the thermostat and the heater. The two parts pass the test.
I thought that the problem is from the electronic part.
The question is: Can I connect the thermostat-heater directly to power and adding a switch on the AC cable?
