No. The pilot valve is closed when no flame is sensed by the thermocouple.
The output of the thermocouple is linear.
You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.
Usually you should replace spare parts for your boiler every 3-5 years. Maintenance should be done every six months to see if anything needs replacing.
The thermocouple which measured the car's coolant temperature failed and so the car overheated.

No. The pilot valve is closed when no flame is sensed by the thermocouple.
To replace a thermocouple on a gas fireplace, first turn off the gas supply and wait for the fireplace to cool down. Locate the thermocouple near the pilot light and unscrew the old one from the gas line, then install the new thermocouple by screwing it in place and reassemble the gas line. Finally, relight the pilot light and test the fireplace to ensure the new thermocouple is working properly.
To replace the thermocouple on a gas water heater, first turn off the gas supply and water heater. Locate the thermocouple near the pilot light and unscrew it from the control valve. Install the new thermocouple by screwing it into place and reassemble the water heater. Finally, turn the gas supply and water heater back on to test the new thermocouple.
You do NOT clean a thermocouple. They are really inexpensive and when they are giving problems have a LMP / or Gas fitter replace it
To replace the thermocouple in your furnace, first turn off the gas supply and power to the furnace. Locate the thermocouple near the pilot light and unscrew it from the gas valve. Install the new thermocouple by screwing it into place and reassemble any parts that were removed. Finally, turn the gas supply and power back on and test the furnace to ensure it is working properly.
A system or combi boiler is a great replacement for a Baxi back boiler. Boiler Hut can help with selection and installation.
To replace a Honeywell thermocouple effectively, follow these steps: Turn off the gas supply to the appliance. Remove the old thermocouple by unscrewing it from the gas valve. Install the new thermocouple by screwing it into the gas valve. Ensure it is securely attached and reassemble any parts that were removed. Turn on the gas supply and test the appliance to ensure it is working properly.
There are many pictures of this on Google.
A Thermocouple is simply a temperature-sensor consisting of a junction between two metals, where the tiny voltage between them varies with temperature. This change in voltage can be detected and acted upon by the electronics controlling such things as boilers.
To troubleshoot and replace a faulty thermocouple in a State Select water heater, follow these steps: Turn off the gas supply to the water heater. Locate the thermocouple near the pilot light assembly. Disconnect the thermocouple from the control valve. Remove the old thermocouple from the pilot assembly. Install the new thermocouple in the same position. Reconnect the thermocouple to the control valve. Turn on the gas supply and relight the pilot light. Test the water heater to ensure it is functioning properly. If you encounter any difficulties or are unsure about any step, consult a professional plumber for assistance.
