How Component-Level Repairs Extend the Life of Your Automation System
When a drive, PLC, or HMI fails, many repair shops reach for board-level swaps—replacing entire circuit boards or assemblies. While that can get equipment back online, it often ignores deeper issues, limits long-term reliability, and can even shorten the lifespan of your automation system.
At Delta Automation, we specialize in component-level repairs, going beyond surface fixes to restore performance at the root cause. Here’s why this method matters, how it saves you money, and real examples of how it keeps factories running.
Board-Level Swaps: A Quick Fix With Hidden Risks
Many repair shops operate like part-swapping warehouses. Instead of diagnosing the true failure, they pull an entire circuit board and replace it with another pulled from stock.
- Masked issues: The root cause—like a faulty capacitor or overheated power transistor—often remains unaddressed.
- Shortened lifespan: A swapped board may carry its own wear and tear, leading to another breakdown months later.
- Higher costs over time: Repeat failures, extra downtime, and premature replacements add up.
It’s the industrial equivalent of replacing the whole engine because of a spark plug issue.
Component-Level Repairs: Precision That Pays Off
Our technicians take a different path. Using advanced test benches, schematics, and decades of experience, we repair down to the individual component—ICs, resistors, capacitors, power modules, connectors, and more.
Benefits
- True root-cause elimination: We fix the exact failing part and reinforce weak points.
- Extended equipment life: Drives and PLCs often run for years longer after component-level repair.
- Lower total cost of ownership: One thorough repair prevents repeated downtime and avoids the cost of new equipment.
- OEM-level standards: As a factory-authorized repair center, Delta maintains exact tolerances and uses high-quality replacement components.
Board Swaps vs. Component Repairs at a Glance
| Factor | Board-Level Swap | Component-Level Repair |
|---|---|---|
| Root Cause Addressed | Often ignored | Fully diagnosed & corrected |
| Reliability | Short-term | Long-term |
| Cost | Lower upfront, higher lifetime | Fair upfront, lower lifetime |
| Downtime Risk | Repeat failures likely | Extended uptime |
| Sustainability | Wasteful (discard boards) | Efficient (reuse, less e-waste) |
| Fit for Legacy Systems | Limited | Excellent |
Case Study #1: Servo Drive Saved from Repeat Failures
A manufacturer arrived after their servo drive failed twice in less than a year despite service by another shop. The previous repairer swapped a control board but left degraded capacitors untouched.
- Delta diagnostics identified multiple failing capacitors and a weak power transistor.
- After precise replacement and testing, the drive has run without failure for over three years.
- Result: ~$18,000 saved in avoided replacements and downtime.

Case Study #2: PLC Brought Back from “Obsolete” Status
An OEM told a customer their discontinued Allen-Bradley PLC could no longer be repaired or supported. A third-party shop attempted a board swap that failed within weeks.
- Delta performed component-level analysis and replaced a series of corroded IC sockets.
- The unit was fully restored and returned to production.
- Result: Legacy system extended another five years, avoiding a costly migration project.
Why This Approach Matters in 2025
With tariffs and supply chain disruptions pushing up the cost and lead times of replacement parts, keeping legacy equipment alive is more valuable than ever. Board-level swaps may buy time, but component-level repair maximizes every dollar: less waste, longer uptime, and more budget flexibility.
Frequently Asked Questions
Isn’t a board swap faster than component-level repair?
Not always. Our diagnostic process is streamlined, and a proper component-level repair often prevents future failures that would create more downtime overall.
Will my warranty be affected?
Delta provides a 1-year repair warranty, giving you confidence the issue won’t return.
Can you repair parts marked “obsolete” by the OEM?
Yes—component-level repairs are one of the best ways to keep discontinued equipment running reliably.
How do I know if component-level repair is right for my equipment?
If you’re experiencing repeat failures or replacement parts are scarce or costly, component-level repair is likely the smarter option.
