All commercial equipment, from a deep fryer in a commercial kitchen to a conveyor belt in a manufacturing facility, will eventually fail. When unexpected breakdowns happen, they stall production, distract technicians from routine preventive maintenance tasks, and cost your organization serious money.
As a first step to managing unplanned downtime, operation & maintenance (O&M) managers need to understand why equipment fails.
This article covers the five most common causes of equipment failure and how to prevent them. You won't be able to eliminate failure entirely, but you can learn how to reduce its impact on operations.
What is equipment failure?
Equipment failure occurs when industrial machinery, assets, or systems stop functioning, resulting in unplanned downtime and production losses.
Equipment failure is more costly than you think
While lost production time is the most obvious issue, the consequences of equipment failure are far-reaching:
- The cost of unplanned overtime for technicians
- Stand-down costs for machine operators
- The increased cost of urgently shipping spare parts from suppliers
- Wasted raw materials, such as perished food production ingredients
- Defective products or a sharp increase in quality assurance failures
- Reduction in customer satisfaction levels and quality perception
- Lost business due to not meeting delivery targets or promised dates
- Opportunity cost due to focusing excess resources on repairing the asset
79% of teams saw the amount of unplanned downtime stay the same or increase over the past year, and 39% say the cost of downtime is rising.
The 5 common causes of equipment failure
There are a few major reasons equipment failure happens.
1. Aging equipment
According to aPlant Engineering Maintenance study, aging equipment is the leading cause of equipment failure, accounting for 40 percent of unplanned downtime in plants.
Assets that consistently run year after year require more frequent repairs over time. This deterioration translates to more money spent on parts, inventory shipping fees, and production interruptions.
The aging process also requires technicians to switch from preventive maintenance (PM) to reactive maintenance more often. And the more outdated an asset becomes, the harder it is to procure replacement parts.
For these reasons, plants should consider allowing assets that have passed their useful life to run to failure.
Though purchasing new machinery is expensive, most organizations save money in the long run through less frequent repair expenses, increased production, and more efficient parts management.
2. Operator error
Another common cause of equipment failure is operator error. Sometimes machine operators make mistakes due to fatigue, forgetfulness, inexperience, or lack of training. According to the State of Industrial Maintenance 2026 report, operator error is among the top reasons unplanned downtime has increased over the past year.
Most plants prepare machine operators to properly run complex equipment with adequate training, accessible standard operating procedures (SOPs), and clear safety guidelines. But it's not unheard of for workers to occasionally work on unfamiliar machines.
An untrained operator may not have the specialized knowledge to confidently run the machine. This can cause an equipment breakdown or a workplace accident.
3. Lack of preventive maintenance
World-class equipment maintenance programs practice preventive maintenance because it decreases costly equipment failure and downtime.
Reactive maintenance has its place. But organizations using primarily run-to-failure maintenance miss opportunities to solve minor issues before they become expensive problems. Delayed maintenance tasks reduce asset lifespans and increase capital replacement needs.

4. Environmental factors
The environment where your equipment operates directly impacts its longevity and performance. External conditions accelerate wear and tear, leading to premature equipment failure.
Common environmental threats to industrial equipment include:
- Extreme temperatures: Affect lubricants, seals, and electronic components
- High humidity: Causes rust on unprotected metal surfaces and electrical issues
- Dust and debris: Clogs filters and moving parts, causing overheating
- Corrosive chemicals: Accelerates component degradation in processing environments
- Chemical exposure in food processing: Cleaning agents and food acids corrode stainless steel equipment
- Dust in manufacturing: Metal shavings and particulates damage precision machinery
Your maintenance team should assess these risks and implement protective controls, such as climate systems or enclosures, to mitigate environmental damage.
5. Incorrect installation
An asset's reliability starts with proper installation. Mistakes during commissioning create chronic performance issues that can lead to early equipment failure.
Common installation errors include component misalignment, incorrect wiring, and failure to follow manufacturer specifications. These issues create stress on equipment from day one.
While installation problems may not appear immediately, they cause vibrations, excessive wear, and electrical faults over time. Training technicians properly and including detailed installation procedures in your computerized maintenance management system (CMMS) software can help prevent these costly mistakes.
4 ways to prevent equipment failure
You can trace every equipment failure to a root cause. Uncovering that original "falling domino" should be your primary goal for increasing operational reliability.
Effective root cause analysis techniques for maintenance teams include:
- The 5 Whys: Systematic questioning to identify underlying causes
- Fishbone diagrams: Visual mapping of potential failure contributors
- Failure mode analysis: Comprehensive review of asset breakdown patterns
Finding the root cause is only the starting point. Here are proven strategies to prevent equipment failure and minimize its operational impact.
1. Provide thorough operator training and maintain compliance
Ensuring equipment operators receive adequate training minimizes failures that stem from human error. According to the 2026 State of Industrial Maintenance report, “poor knowledge transfer or training” was one of the top three reasons companies experienced more downtime.
Managers should also build redundancy into their operations by training workers how to use machines they don't normally operate. That way, someone who has been properly trained according to Occupational Safety and Health Administration (OSHA) standards will always be available.
2. Monitor and analyze equipment digitally
Connected IoT systems make monitoring asset health and preventing failures simpler. By capturing equipment meter readings and sensor data in your CMMS, you can automate asset tracking and get a high-level view of all your assets.
Remote condition monitoring delivers real time and cost savings by catching unusual operating conditions before equipment breaks down.
3. Attach standard operating procedures to work orders
SOPs ensure that technicians properly maintain and service equipment the same way every time. By attaching approved SOPs to work orders, maintenance managers ensure that technicians carry out repairs, parts replacement, and other maintenance tasks effectively and consistently.
4. Run routine maintenance inspections
Regular inspections prevent minor issues from escalating into costly equipment failures. MaintainX checklists help technicians easily conduct these routine inspections. They also create a "paper trail" for maintenance managers to analyze asset health.

Equipment failure FAQs
What is the most common cause of equipment failure in manufacturing facilities?
Industry research consistently cites aging equipment as a leading cause of unplanned downtime in manufacturing. Natural wear and tear on mechanical components, outdated technology, and difficulty sourcing replacement parts all contribute to a higher failure rate as assets age.
How do maintenance teams measure equipment failure prevention success in manufacturing facilities?
Track key performance indicators that demonstrate prevention effectiveness: Mean Time Between Failures (MTBF) should increase while Mean Time to Repair (MTTR) decreases. Also monitor your planned versus unplanned maintenance ratio.
When should industrial facilities replace equipment versus continuing repairs?
The decision to replace versus repair depends on a cost-benefit analysis. You should consider replacing an asset when the total cost of ownership—including rising repair costs, frequent downtime, and inefficient operation—exceeds the cost of a new, more reliable unit.
What environmental factors most commonly cause equipment failure in manufacturing?
In manufacturing, common environmental factors include extreme temperatures, which affect lubricants and electronics; high levels of dust or particulates, which clog filters and moving parts; and moisture or humidity, which lead to corrosion and electrical shorts. Exposure to corrosive chemicals that production processes use also accelerates equipment degradation.
How do maintenance management systems help prevent equipment failures?
A CMMS helps prevent failures by automating PM schedules, tracking asset history to identify failure patterns, and enabling condition-based monitoring. By centralizing all maintenance data, a CMMS provides the insights your team needs to shift from a reactive to a proactive maintenance strategy.
