Water heater is one of the essential home appliances in our daily life, but if it is not used properly, some malfunctions will occur, and one of the most common is the failure of the wind pressure switch. Wind pressure switch is one of the important parts of the water heater, its role is to detect the gas combustion of the water heater, if the combustion is not normal, it will automatically shut off the gas valve, so as to ensure the safety of users. Therefore, it is very important to correctly adjust the air pressure switch of the water heater, this article will provide you with a detailed introduction to the adjustment of the air pressure switch of the water heater to help you avoid failure.
Water heater air pressure switch adjustment (how to correctly adjust to avoid failure).
First, what is the wind pressure switch?
The wind pressure switch is a safety device in the water heater, which ensures the safety of the user by detecting the gas combustion. When the gas combustion is not normal, the wind pressure switch will automatically close the gas valve, thus avoiding gas leakage and ensuring the safety of users.
Second, why adjust the wind pressure switch?
Wind pressure switch is one of the important parts of the water heater, if the wind pressure switch fails, it will lead to the water heater can not work properly, and even cause safety accidents. Therefore, it is very important to adjust the wind pressure switch correctly to ensure the normal operation of the water heater and avoid failure.
Third, how to adjust the wind pressure switch?
1. Prepare tools
Adjusting the air pressure switch requires some tools, including wrenches, screwdrivers, batteries and so on.
2. Determine the location of the air pressure switch
The air pressure switch is usually located inside the combustion chamber of the water heater, and you need to open the water heater shell to see it. Before opening the water heater shell, you need to turn off the water heater’s power and gas valve to avoid electric shock and gas leakage.
3. Adjust the air pressure switch
Adjusting the wind pressure switch needs to be divided into two steps: first, adjust the position of the wind pressure switch, and then adjust the sensitivity of the wind pressure switch.
(1) Adjusting the position of the air pressure switch
The position of the air pressure switch needs to be determined according to the model and brand of the water heater, and usually needs to refer to the instruction manual of the water heater. After determining the position of the air pressure switch, you need to use a wrench to loosen the fixing screws of the air pressure switch, then adjust the air pressure switch to the correct position, and finally tighten the screws.
(2) Adjusting the sensitivity of the wind pressure switch
Adjusting the sensitivity of the wind pressure switch requires the use of batteries to test. First of all, you need to connect the battery to the two pins of the wind pressure switch, and then open the power supply and gas valve of the water heater, so that the water heater enters the ignition state. When the water heater ignites, the wind pressure switch should be able to sense a change in airflow, which will close the gas valve. If the air pressure switch is unable to sense the change in airflow, the sensitivity of the air pressure switch will need to be adjusted. This is done by using a screwdriver to adjust the adjustment screw on the air pressure switch so that its sensitivity is appropriate for the environment in which the water heater is used.

Fourth, precautions
1. Before adjusting the wind pressure switch, you need to turn off the power supply of the water heater and the gas valve to avoid electric shock and gas leakage.
2. Adjusting the air pressure switch requires the use of some tools, including wrenches, screwdrivers, batteries, etc., need to pay attention to safety.
3. To adjust the air pressure switch, you need to refer to the instruction manual of the water heater and determine the position and sensitivity of the air pressure switch according to the model and brand of the water heater.
In short, the adjustment of the air pressure switch of the water heater is very important to ensure the normal operation of the water heater, to avoid malfunction and safety accidents. When adjusting the air pressure switch, you need to pay attention to safety, refer to the instruction manual of the water heater, and determine the position and sensitivity of the air pressure switch according to the model and brand of the water heater. If you are not sure how to adjust the air pressure switch, it is recommended to call a professional for repair.
