Why Equipment and Technology Fail: The Most Common Reasons

If you’ve ever disassembled an appliance that stopped working or pulled your hair out trying to troubleshoot a frozen computer screen, you may be one of the many people who call equipment and technology unreliable. It can seem as though for every piece of dependable equipment, there’s one that just won’t function properly. However, most technology and machines don’t just fail for one reason. It can be a combination of human, technical, and environmental factors:

Poor Maintenance

If you can’t remember the last time you maintained the machine that is now performing poorly, a lack of maintenance may be to blame. For example, many people troubleshooting food x-ray machines haven’t followed the manufacturer’s maintenance recommendations, such as regularly cleaning the cooling system to prevent debris from compromising the fan. As a result, you may experience problems such as system jams, deterioration of electrical components, and false rejections.

In any technology or equipment, something as simple as a lack of lubrication, dust buildup, or outdated software can prevent it from working at its best and shorten its lifespan.

Wear and Tear

Even if you choose the most highly regarded and top-performing machine on the market, such as an air fryer for your kitchen or a computer system for your business, it won’t last forever. Eventually, most things succumb to wear and tear.

In technology, hardware degrades over time, and moving parts and solid-state components eventually fail due to repeated use, thermal cycling, and material fatigue. However, maintenance activities like lubrication, cleaning, and calibration can often go a long way toward extending their lifespan.

Human Error

Just as machines and equipment can have faults, so can humans. In fact, they can play a leading role in equipment failure. Immediate or long-term damage can occur due to incorrect installation, failure to follow manufacturer procedures, or improper operation.

For example, if an operator were to use a machine beyond its rated capacity, with incorrect settings, or in a way it’s not intended to be used, internal components can become stressed, leading to premature failure. An example would be trying to cook a steak in a toaster. While it’s designed for heating, it’s intended for bread products, not meat. Repeatedly using the toaster in this way could lead to its premature failure.

Overheating

Overheating can occur due to an excessive workload, too much dust in the cooling fans that blocks airflow, and poor environmental conditions. When a machine overheats, its materials can warp, expand, or lose strength. In some cases, they can then damage sensitive electronic systems.

Environmental Conditions

If an environment is harsh for humans to work in, it can be equally harsh for machines.

Dust can clog moving parts and reduce cooling efficiency, while moisture can cause corrosion. Even vibration can be damaging in industrial environments, causing parts to work their way loose or suffer fatigue damage.

Proper environmental controls, such as sealing, insulation, and protective enclosures, may prevent or limit such damage.

Even the most high-quality equipment doesn’t last forever. Equipment fails for a range of reasons, some of which are preventable, such as poor maintenance, human error, and wear and tear.
