HVAC provides us with much-needed relief from scratching heat or frigid outdoor temperatures. Thus, for this amazing machinery to keep working without unexpected breakdowns, we opt for regular maintenance. While maintenance may incorporate repair, replacement, and cleaning, fixing the electric connections and debugging electronics problems is an integral part of it as well. Something that goes haywire in the electric work may lead to bigger problems in your HVAC unit. Let’s discuss a few common HVAC electric problems

Problem With Circuit Breaker Or Fuse:

Has your HVAC unit suddenly stopped working? Most probably, it has tripped a breaker. Moreover, a blown-out fuse can lead to sudden power cutoff. Both circuit breaker and fuse are protective circuitry against high currents. The difference is that you need to replace the fuse, but a breaker is reusable; all you need to do is turn on the tripped breaker.

An Occasional tripped breaker or a blown-out fuse is nothing much to worry about. It may occur because of a power surge. However, if this problem occurs often, there is more than what meets the eyes. For example, a dirty furnace filter can lead to this problem. Dirt and debris from this filter may blow into the blower motor. This causes the motor to overheat, demanding more energy and then blowing the fuse.

Capacitor Problems:

Motors used in HVAC units have a starting and a running capacitor. Starting capacitor helps by providing the necessary starting charge and current. On the other hand, the running capacitor comes in handy during motor operation through equal charge distribution. Nonetheless, if any of these capacitors stop working, you will experience motor problems. Either the motor will refuse to start or shudder during operation, eventually coming to a halt. Hence, it would be best to ring a technician in case of capacitor problems.

Some Lose Connections:

Some loose wirings here, and there is nothing to fret about. A technician can easily resolve this issue by tightening them, and your HVAC unit will be up and running in no time. However, loose connections may indicate a larger wiring problem; it’s like the surface of an iceberg. Hence, schedule a maintenance checkup from your HVAC technician to resolve any wiring issues.

Damaged Connection:

Frayed connection, corrosion, and loose ends will interrupt the flow of electricity in the unit. This will lead to some undesirable consequences, such as overheating. The aftermath of damaged connections is easy to understand; when electricity cannot flow in the circuit smoothly, parts of your HVAC system will not get enough energy to operate. This can lead to all kinds of problems such as overheating, breakdowns, and high utility bills.


HVAC electric problems are hard to solve on your own, so you will need aid from professional technicians to help you resolve your issues. However, an inexperienced technician may cause more trouble than relief. Hence, always opt for experienced and well-trained professionals like those at Crump A/C and Heating.
