Excuse me, how to short-circuit the wind pressure switch of the forced exhaust water heater? The control panel protection can't start after my fire king is short-circuited.

One thing must be remembered, even if there is no fault, the maintenance interval of gas water heaters should not exceed two years. But in my investigation, I found that most users simply don't pay attention to the maintenance of high-power products such as gas water heaters, and even want to simplify the handling when problems arise.

Generally speaking, the wind pressure switch detects the air pressure in the volute. Under normal working conditions, the air pressure here is slightly lower than the surrounding air pressure. With the increase of carbon deposition in heat exchanger, turbine efficiency decreases and air pressure moves to positive pressure. Until it approaches the threshold value of the wind pressure switch, the wind pressure switch will automatically cut off and indirectly cut off the main power supply, so that the whole water heater will stop working.

Other factors should also be considered, such as motor failure, power failure, solenoid valve failure, etc.

Gas water heater is a high-power product, and its internal control system is a big project.

Best wishes.
