Diagnostic Mastery: How To Inspect Equipment And Troubleshoot Faults

Inspections and fault-finding are where technicians prove their value. Use a simple, repeatable method.

A practical 8-step troubleshooting approach

Define the problem

Get the symptom from the operator or BMS alarm. Ask: What changed? Since when? Any pattern?

Verify the symptom

Reproduce if safe. Check indicators, HMI alarms, and physical evidence (noise, smell, temperature).

Make it safe

Apply LOTO as needed. Discharge stored energies. Put barriers/signage.

Break the system into modules

Input (supply), control, actuation, output. Check each in order.

Use the right instruments

Multimeter, clamp meter, insulation tester, thermal camera, vibration pen, pressure gauge.

Change one variable at a time

Swap a suspected sensor; bypass under procedure; reset parameters carefully.

Fix, then verify

After replacement or adjustment, run under load. Monitor for at least one full cycle.

Document and learn

Log cause codes, photos, part numbers, and lessons learned; update PM frequencies if needed.

Visual inspection checklist (Look-Listen-Feel-Smell)

Look: loose wiring, frayed belts, oil leaks, rust, misalignment, unusual wear patterns.
Listen: grinding, whistling, arcing snaps, relay chatter, cavitation.
Feel: overheating housings, vibration, air drafts where none should exist.
Smell: burnt insulation, refrigerant, oil, acetylene, or ozone.

Electrical fault-finding quick tips

Nuisance tripping: measure inrush current, check cable sizing and protective devices.
VFD trips: note fault code, check motor bearings for drag, inspect cable shielding and grounding.
Sensor failures: verify supply voltage, test signal output with a meter, confirm PLC input status.
Intermittent faults: look for loose terminals, thermal expansion issues, and water ingress.

Mechanical fault-finding quick tips

Overheating bearings: check lubrication schedule and grease type; verify alignment.
Belt squeal: tension, pulley wear, and belt profile compatibility.
Cavitating pumps: blocked strainers, suction head issues, or air leaks in suction line.
Air leaks: use ultrasonic leak detector or soapy water for pneumatics.

HVAC troubleshooting patterns

Poor cooling: clogged strainers or coils, low refrigerant, fouled cooling tower, incorrect setpoints.
Short cycling compressors: faulty pressure switches, incorrect superheat, or control logic issues.
High energy use: stuck dampers, simultaneous heating and cooling, fouled filters.

Frequently Asked Questions

1) Do I need ANRE authorization to work as a maintenance technician in Romania?

Not for every role, but if you will perform electrical work on installations, many employers require appropriate ANRE authorization levels. It strengthens your profile and may boost your salary. Non-electrical roles (mechanical/HVAC-only) may not require it, but cross-skilled techs are in higher demand.

2) What CMMS should I learn?

Focus on concepts rather than a single tool: asset hierarchies, work orders, PM scheduling, cause/action coding, and KPI dashboards. If you can, gain exposure to SAP PM or IBM Maximo since they are widespread in larger companies. For FM, tools like Infor EAM or CAFM systems are common.

3) Which city offers the best opportunities for technicians?

It depends on your specialty. Bucharest has broad FM and critical facility roles; Timisoara is strong in automotive and electronics; Cluj-Napoca mixes electronics and logistics with rising data center work; Iasi has pharma, healthcare, and public sector opportunities. All four cities have steady demand.

4) What salary can I expect as a junior technician?

Entry-level roles typically pay around 3,500 - 5,500 RON net per month (about 700 - 1,100 EUR), depending on shift work, city, and sector. Overtime and night shifts can raise total pay.

5) How can I prove troubleshooting ability during interviews?

Bring a short portfolio: a before/after repair story with photos, a 5 Whys analysis, and a sample PM checklist you improved. Be ready to walk through your step-by-step diagnostic method and explain a real incident with measurable results (e.g., downtime reduced by X minutes).

6) Are HVAC and refrigeration certifications mandatory?

If you handle refrigerants, EU F-Gas certification is required. For general HVAC maintenance without refrigerant handling, employers may not require it, but basic HVAC training plus BMS familiarity is valuable and often rewarded.

7) What is the difference between preventive and predictive maintenance?

Preventive maintenance is time or usage-based (e.g., quarterly inspections). Predictive maintenance relies on condition monitoring data (vibration, temperature, oil analysis) to service equipment only when indicators suggest degradation. Many sites use a hybrid approach for best results.
