What causes furnace circuit board failure?
Failed transistors: The transistors in the control board are susceptible to damage due to power surges, static electricity, and age. Transistors are often the first part of a control board to fail. Loose wiring: The vibrations of the furnace over the years can cause wiring in the control board to shake loose.
Why do control boards go bad?
Transistors are typically the first part to fail in a control board. Once again, the damaging heat and energy that hits those transistors due to voltage spikes, or even a little bit of static electricity, can wear out a board prematurely. This is going to change the composition of the materials they’re made of.
How can you tell if a circuit board is bad?
Examine the circuit board and search for signs such as crushed components, bulges, damaged wires, cracks, misplaced or extra solder, burn marks and scratches that indicate that the board is either bad or requires replacement and professional assistance.
