Valid Signs that Your Furnace Control Board Needs Replacement
Today with the advance in technology, you must admit that the field of power fitting has become a hard nut to crack.
The modern furnace as compared to its previous counterparts which were basically huge ovens with attached pipes hooked on them is a complete marvel of technology, in an efficient way though.
The control board in a furnace is the core of how everything works out and runs a series of functions including firing up the electronic ignition, checking burner unit, shutting off the gas, activating the blower, opening gas valves and venting the heat exchanger.
However, the control board just like any other merchandize is not superficial and can malfunction at the least desirable moment leaving your furnace’s operation in ruins. The moment this happens, it makes better sense to get in touch with your heating contractor who can solve the issue in the most effective and efficient way.
What to look out for?
Well it so happens that some occurrences might just be a false alarm, but not always. While you are not the exact expert to make a sound judgment, here are signs that your furnace control board is malfunctioning:-
- Un-even temperatures
Say your furnace suddenly feels too cold or too hot with the thermostat setting all fine, then this might be due to a control board turning off components too soon or releasing them too long. Although there may be many reasons as to this defect, the control board is often the main cause.
- Diagnostic indications
While most control boards have LED lights that indicate the onset of a fault in operation, you should open up the control board access panel to check for any red alert lights if your furnace starts acting up. The manufacturer must have already fitted a diagnostic chart on the inside of the board which helps interpret the warning lights.
- Interruption of regular events sequence
This means you will need to master your furnace’s operation sequence. You will only need to stay near it and listen to how it functions, this will help you detect when normal functioning is interrupted. May be the blower stops suddenly or gas jets stops activation, blower continues to run after everything shuts off or igniter is not coming on, all these irregularities in the normal running of the furnace could pose major indications of control board malfunction.
