The relay monitors the current sensing loop

then turn four full rotations clockwise to engage the spring before fine-tuning

This usually indicates the control board is not "seeing" the flame through the sensor

Soft Ignition Profile: The slow-open feature reduces mechanical stress on the heat exchanger during the ignition cycle

Amana-Goodman B1809913S HSI Board Els PW 17895 The relay monitors the currentThe Amana Goodman B1809913S HSI Board is a critical OEM replacement control board engineered for precision timing in hot surface ignition sequences. Designed to interface via a specialized 9 pin connector, this integrated module manages the inducer fan motor, gas valve, and blower motor cycles within Amana and Goodman furnace models. This microprocessor based board stabilizes the ignitor output and monitors flame sensor inputs to ensure safe,
