Transformers
HVAC transformers are used in air conditioning systems, furnaces, air handlers, and heat pumps. They convert high-voltage electricity into low-voltage that is suitable for control systems and thermostats. Transformers support the connection between thermostats and HVAC equipment by providing power to circuit boards, contactors, and relays. They are a necessity for control parts because they provide the low voltage needed for these devices to function safely....Read more
It’s important for transformers to supply steady power. Without that, thermostats and other controls can’t receive or send signals. The result would mean HVAC systems wouldn’t be able to adjust and maintain temperature or manage zones.
Transformers can malfunction or stop working because of power surges, overheating, or short circuits. Blank thermostats can be a red flag that there is an issue with transformers along with thermostats that aren’t responding. Other indicators that transformers aren’t working properly are tripped breakers or blown fuses.
Transformers should be part of the preventative maintenance procedure. Looking over transformers can bring awareness to melted insulation, burn marks, or corrosion. Also, looking for loose terminals or frayed wires should be done during scheduled maintenance. It is also a good idea to use a multimeter to verify the transformer’s voltage output is correct.
