What should I do if the water heater ignites and does not burn in wet weather?

The basic working principle of gas water heater is that cold water enters the water heater and flows through the water-gas linkage valve body to push the water-gas linkage valve under a certain water pressure difference. At the same time, press the micro switch of DC power supply, turn on the power supply and start the pulse igniter. At the same time, open the gas transmission solenoid valve, and continue to automatically re-ignite through the pulse igniter until the ignition successfully enters the normal working state. This process lasts about 5~ 10 second. When the gas water heater cannot meet the requirements of water shortage, water pressure shortage, electricity shortage, gas shortage, high hot water temperature, accidental flameout, etc. The pulse igniter will automatically cut off the power supply by detecting the signal fed back by the induction needle during working or ignition, and immediately return to the original normally closed valve state when the gas transmission solenoid valve is powered off, that is to say, the gas path has been cut off at this time, and the gas water heater is in the closed state for safety protection.

Maybe your water heater is out of power because of poor circuit contact caused by humid air. Lack of electricity and insufficient water pressure are the main reasons for ignition failure.
