Electronic Control Failures
By Brian Lucas
Springtime is a good time to service your HVAC unit, preventative
maintenance can help keep your air conditioning system running correctly.
We often overlook the electronic components when preforming DIY HVAC
maintenance. Common whole home heating and cooling system electrical
component failures can start with a resistor or capacitor and end with compressor
or fan motors. Let’s look at some of the most common electrical component
failures and what can be done to detect them early.
Capacitors are used to improve the operating characteristics of a single phase
motor such as fans and compressors. They draw a large voltage to get the HVAC
system running and up to the desired output. Basically, the capacitor stores
electricity ready to feed it to the solenoid. The more the capacitor is used, the
quicker it will fail. As it ages, it holds fewer volts and eventually will fail all
together. Replacement of the capacitor will get the HVAC system back up and
running.
Solenoids are responsible for converting the electrical energy into mechanical
energy in the ac system. It helps control the flow of liquid or gas within the
system. It can fail in three ways, the valve may not open, may only party close,
or may make erratic sounds. These may be caused by power failures, improper
maintenance, and loss of pressure, missing components, condensation, or coil
failures. It’s important to narrow down the cause as simply replacing the solenoid
may not fix the
problem.

The compressor and fan or blower controls are other electrical components that
experience common failure within HVAC systems. These components are outside
and use the outdoor air to transfer the heat off of the compressor coils. Some of
the common electrical failures you may encounter are: short cycling, the fan can
stop working or make loud noises, the blower motor seizes, and the compressor
can freeze up or stop working, moisture in the compressor, overcharged or dirty
compressor. None of these are easy to repair; you should consult with your local
air conditioner service company before attempting these repairs. To prevent these
types of electrical component failures, we recommend removing debris and dirt
from the outdoor unit and preforming preventative maintenance seasonally.
The contactor in a HVAC system connects to main system to the power supply.
It is controlled when the thermostat engages, as it ages, the contacts can become
pitted, burned, or even welded together causing the air conditioning unit not to
turn on, to freeze up or elicit the systems’ emergency shut off. Inspection of this
should be part of the preventative maintenance. Replacement of the contactor
should be performed by your professional HVAC service technician.
Circuit boards essentially run the whole home HVAC system and can be hard
to diagnose as electrical component faults. Their wires can become loose, short
circuit, or the circuits stop working due to other system faults. Troubleshooting
these failures takes specialized equipment and knowledge of the specific HVAC
system.
It’s always best to keep up with the preventative maintenance on your HVAC
system to ensure long life and the most efficient function possible. Call the HVAC
professionals at Rainbow Lakes Heating and AC to schedule your consultation
