A homeowner in Allen, TX reached out after noticing their brand-new furnace was randomly cycling on and off. Understandably concerned, the homeowner suspected the control board might be the culprit.
Our technician arrived and performed a thorough diagnostic. What we found was simpler than expected — a blown low-voltage fuse. This small component can cause the furnace to behave erratically, even on a brand-new unit.
We replaced the fuse, and the furnace returned to normal operation right away. No board replacement was needed, which saved the homeowner both time and money.
