Circuit boards serve as “brains” for any electronic device. They control all actions and procedures, which take place within a particular working mechanism. The board represents one or more dielectric layers, on which a conductive pattern is applied. There can be two conductive patterns within one piece. They also can be arranged in a network.
The product is the basis for securing particular elements of radio electronics in order to connect them together. Solder or solder paste is used to connect separate parts with a conductive pattern.
A furnace circuit board is a piece that is designed to control the whole heating system. Within a working unit, it performs the following tasks:
- Start the device;
- Initiate the heating process;
- End the duty circle;
- Activate the blower;
- Control the optimal temperature in a room;
- Vent the exchanger;
- Monitor the temperature of all working part of the system to prevent overheating;
- Open the gas valve;
- Alert to malfunctions in the system.
It comes out that it is the circuit board that is responsible for the whole operating circle of the device. One small part runs a big mechanism to deliver heat to you.
How to Understand that Something is Wrong with the Circuit Board?
There are indicators that may signal the necessity to call service technicians. These include:
- Too cold or too warm air in a premise. If you feel uncomfortable in a room due to the wrong temperature, pay attention to the device. If the thermostat functions well, then malfunction with the furnace control board can be the reason.
- Trace the regular sequence of operating steps. Note that in this case do not open the working mechanism. Just listen to it and identify possible problems with ignition and heating.
- If any problem occurs during operation, an alert signal lights on the panel. In this case, it is necessary to call technicians.
In order to prevent serious problems, it is necessary to conduct diagnosis timely. During an examination, one can identify hidden problems. Thus, do not neglect maintenance and check all the systems of the device for proper functioning.
