If you are talking about a wall switch for the heater, check to see if the heater has its own internal thermostat or switch as this might be in the off position and not allow the heater to turn on. If you are talking about a switch on the heater itself, then yes in all probability the switch is not working.
shut off the power to the box, switch out the breaker and resture the power
IT turns the heater on and off!
There are two types of thermostats. One is a line voltage stat. This is in effect a switch and when turned to the off position the voltage is interrupted and the heater will not operate. The other type of stat is low voltage. There will be a relay in the baseboard heater that the thermostat is connected to. With this type if installation to turn the power completely off you will have to turn the breaker off that feeds the circuit.
No, and this is a very good energy saving practice.
It could be the high speed heater motor relay is stuck on or the switch itself is broken.
There is no Logical reason to do this. There is an off switch too btw
Turn the switch off.
the power switch on a camera turns on or off the camera.
It's not a bad idea to turn off the water heater especially if it is electric. It will consume power the whole time you are gone to keep the water hot and wastes a lot of electricity.
Well do you get hot water? If not, then it doesnt work.
Maybe a bad switch
no power on the power windows switch
