What does TCO mean on a water heater?
The TCO or thermal cut off is located on front of combustion chamber. If temperature inside combustion chamber exceeds 180°F (160°-200° depending on model), the TCO trips and causes gas control valve to shut off gas to burner.
What does a thermal cutoff switch do?
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.
How do you reset the thermal switch on a water heater?

So right here is what's called a thermal reset switch and it's kind of right in between these two it's a little button that can pop out sometimes.
Why does the thermal switch on my water heater keep tripping?
When a water heater starts tripping the ECO repeatedly, it's time to call a plumber for service. There's a good chance that the water in the tank is dangerously hot, and since the problem is usually caused by a failed component, it won't get better until the bad part is identified and replaced.
How do I know if my thermal switch is working?
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.
How do I know if my thermal fuse is blown?
How to tell if a thermal fuse has blown? To test if your thermal fuse has blown, touch the right side of your multimeter lead to the right side of the fuse, and repeat with the left multimeter lead. If the multimeter needle fails to move, this indicates the thermal fuse has blown.
Can you bypass a thermal switch?
The thermal fuse will look like a thin strip of white plastic with a wire coming out of each end. In order to bypass the thermal fuse, use electrical tape to tape the two ends together. The thermal fuse will then be bypassed. Turn the dryer on to a heat cycle for no more than 90 seconds.

Why does my water heater keep needing to be reset?
In some cases, the water heater reset button will repeatedly trip. This is a warning sign of a larger issue such as a faulty thermostat, loose wiring, corroded parts, a grounding problem, or a malfunctioning high limit switch.
How long do you hold the reset button on a hot water heater?
Some heaters may not click when you press on the reset button. If you don't hear the click even after pressing on the button for about five seconds, reassemble the heater anyway. It will probably still restore hot water.
Why does my furnace keep tripping the reset button?
If your furnace reset button keeps tripping, it's most likely that your heater is overheating. This may indicate a need for heating system repair work that needs to be addressed.
What does a thermal cut out do on a shower?
A TCO is an important safety component in an Electric shower. The function of this part is to cut the power to the heater element(s) 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 does a thermal switch protect the circuit?
The Purpose of a Thermal Protector The thermal protection is present to turn the motor off when excessive heat is generated within the motor circuitry. This safety feature halts the temperature climb before it can burn up the motor.
What is thermal cut?
Thermal cutting primarily means the use of energy in various forms to cut virtually any shape from iron and nonferrous materials out of sheets or large slabs. These are the grades of the material which are usually referred as “Flats” in the metal processing industries.

Pumps and thermal cut outs - Pump engineering - Eng-Tips
Hi i have a well pump about 23m down a well. It's under a quarter ton manhole cover ... at certain times of year the pump cuts out, needing a manual reset. the reset is on the low pressure head at the top of the well - but under the manhole cover.
What is a PTC switch?
Another type of thermal switch is a PTC (Positive Temperature Coefficient) thermistor; these thermistors have a "switch" temperature at which the resistance suddenly rises rapidly, limiting the current through the circuit. When used in conjunction with a thermistor relay, the PTC will switch off an electrical system at a desired temperature. Typical use is for motor overheat protection. These devices are not a true “switch” as they do not disengage completely and there is always some resistance across the switch. Devices also apply PTC tech as a PTC thermistor sensor, this is different from a cutout and can confuse amateur electronic technicians.
Why do microprocessors have thermal switches?
Thermal switches on microprocessors often stop only the fetching of instructions to execute, reducing the clock rate to zero until a lower temperature is reached , while maintaining power to the cache to prevent data loss (although a second switch, with a higher triggering temperature, usually turns off even the cache and forces the computer to reboot). This mitigates the impact of programs resembling power viruses on the processor's longevity, while still accommodating their possible legitimate uses; it can also make overclocking possible with less risk.
What is thermal cutoff?
A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).
Do recessed lights have thermal switches?
Thermal switches are included in some light fixtures, particularly with recessed lights, where excessive heat is most likely to occur. This may lead to "cycling", where a light turns off and back on every few minutes. Flashing incandescent Christmas lights take advantage of this effect.
What is TCO (total cost of ownership)?
Total cost of ownership (TCO) is an estimation of the expenses associated with purchasing, deploying, using and retiring a product or piece of equipment.
What factors determine TCO?
The overall TCO includes direct and indirect expenses, as well as some intangible ones that may be assigned a monetary value.
The challenges with calculating TCO
There are several methodologies and software tools to calculate the total cost of ownership, but the process is not perfect. Many enterprises fail to define a singular methodology. This is bad because they cannot base purchasing decisions on uniform information.
Best practices to optimize TCO calculations
Enterprise managers and purchasing decision-makers complete cost analysis for multiple options, then compare TCOs to determine overall costs and, ultimately, the lowest long-term cost.
