    Troubleshooting Flashing Pilot Light Issues

    Identifying the root cause of a flashing pilot light is crucial for effective troubleshooting. Start by checking the water pressure gauge. If the pressure is below the recommended level, the boiler will not function properly. Next, inspect the thermocouple, which is responsible for detecting the pilot flame. A faulty thermocouple will prevent the pilot light from staying lit. Lastly, ensure that the gas supply is uninterrupted and that vents are clear.
