A Thermal Cut out switch (also known as a TCO) is an important safety component of an Electric shower. The function of this part is to cut the power to the heater tank if the temperature inside the unit gets too high. This is to protect the unit from overheating and the user from a sudden scalding.
How do you test a thermal cut out?
Place the thermal cutoff switch on an electric skillet or griddle. Make sure the two prongs face up toward the ceiling. Set the thermostat on the griddle or skillet 25 degrees higher than the cutoff temperature of the switch. Touch both test probes from the multimeter to the prongs on the thermal cutoff switch.

What does a thermal switch do on a water heater?
A thermal switch is installed in newer gas water heaters as a safety device. Blocked vents at the top and bottom of the water heater can cause excessive heat buildup inside the chamber and trip the thermal switch, shutting off the gas supply to the burner assembly.
How does a thermal cutoff switch work?
What is a Thermal Cutoff Switch? A thermal switch is an electromechanical device which opens and closes contacts to control the flow of electrical current in response to temperature change.It cuts off the current to critical machinery when a temperature limit is exceeded preventing potential burn out or failure.
What is a cut out thermostat?
Thermostats are used when a media (e.g. water or air) should be heated to a predefined temperature.They control/regulate the power supply for an immersion heater or a-duct heater, for exampe.

Why does my thermal cutoff keeps blowing?
Dryer Hose or Vent Line Clogged
When dryer hoses or vent lines become clogged it prevents proper air circulation, which will eventually cause your dryer to overheat. This is the most common reason a thermal cutoff fuse keeps tripping. You need to remove the vent line from the back of your dryer and clean it out.

Will dryer light work if thermal fuse is blown?
The dryer thermal fuse is a safety mechanism that detects the temperature of air flowing to the outside vent. If the air too hot, the fuse blows, stopping an electric dryer (a gas dryer keeps running but won’t heat). Unfortunately, if the thermal fuse trips, it must be replaced before the dryer will work again.
Will the dryer run if the thermal fuse is blown?
Will the dryer run if the thermal fuse is blown? Unlike a thermostat that can reset itself, once a dryer thermal fuse blows, it will need to be replaced with a new one before the dryer will run.

How do you trick a thermocouple?
The thermocouple always thinks the pilot is not lit, even if it is. To get hot water, I have to light the pilot, then hold the match on the thermocouple to trick it into thinking the pilot light is touching it. Once it’s warm enough, I pull the match out and turn the knob from “Pilot” to “On”.
