What is the consequence of failing to wire a replacement low voltage transformer in an electronic ignition furnace correctly?

Wiring a replacement low voltage transformer improperly in an electronic ignition furnace can lead to a short circuit of the printed circuit (PC) board. The low voltage transformer is responsible for providing the necessary voltage to the control components of the furnace. If the transformer is wired incorrectly, it can create an electrical fault that sends an incorrect voltage to the PC board.

This can damage sensitive components on the board, potentially leading to failure of the ignition control module or other critical circuits. A short circuit not only compromises the functionality of the furnace but can also create safety hazards, as it may result in sparks or an electrical fire if not addressed. Proper installation of a transformer is crucial to ensure safe and efficient operation of the furnace and to protect its electronic components.
