What is the function of the water heater micro switch?

Many people ask what is the function of the micro switch installed in the water heater? First of all, the micro switch is to use the water pressure to push the micro switch to turn on when you turn on the water heater to control the water heater control panel to work: high pressure ignition and solenoid valve open. (When there is water pressure, the circuit is automatically opened. When there is no water pressure, the circuit is automatically closed)

Good article recommendation: How to install the micro switch, please refer to the answer?

If the micro switch is short-circuited, the water heater will not be controlled, and your water heater will keep working (the high pressure keeps on fire and the solenoid valve keeps on).

To control the water heater, you must use a micro switch. Can not be used in short circuit. In this way, the solenoid valve is always open when you are not using the water heater, and the natural gas will be released and cause danger.

Where is the micro switch located?

The micro switch of gas water heater is generally on the power cord. There will be a square connector on the power cord, and then you will see a red and yellow button, which represents one on and one off; the general gas water heater switch Just below the middle of the water heater, you disassemble the shell of the water heater, and then turn on the water inlet switch of the water heater, you can see that the puller inside will move the micro switch.

The micro switch plays a pivotal role in the water heater, because the water heater ignition, solenoid valve activation, etc. are all controlled by the micro switch, which is equivalent to the micro switch not being closed and all will not work.
