Just as your brain makes you tick, your furnace control board is in charge of keeping your furnace going. So when your heating and cooling system tells you it has a headache, you’ll want to get to the bottom of the problem quickly.
To keep your system functioning, you’ll need to diagnose the cause and fix your furnace’s circuit board burn out. It could be the key to getting your whole system back online.
When your furnace decides to short circuit, faulty wiring could be to blame. Your control board receives the signals from your thermostat that tells your furnace what to do. So if your wires are connected improperly, it’s like a phone that’s off the hook — there’s no way to receive the message.
Water and electrical are two things that just don’t mix. If condensation or water is dripping onto your furnace, your circuit board is also at stake. Water dripping onto the circuit board is a sure-fire way to burn out the board.
Dust and Dirt
Keeping your furnace healthy and clean is important. Built-up dirt usually leads to some kind of furnace trouble down the road. Dirty wiring connections stop working, clogged air filters put excessive loads on the blower motor, possibly causing your control board to short circuit.
