TROUBLESHOOTING & REPAIRS

Find the fault. Restore performance.

A structured approach to cooling problems, electrical faults, leaks and mechanical wear.

01 / UNDERSTAND THE SYSTEM

Troubleshooting & repairs in context.

Weak cooling, water leaks, abnormal sound or repeated alarms can have several causes. Diagnosis helps establish what needs repair before parts are replaced.

Start with the symptom, check the possible causes and confirm the repair scope before replacing parts.

Cooling faults

Weak cooling can involve airflow, controls, refrigerant conditions or the actual room load.

Water leakage

Drain blockage, insulation defects, pump failure and abnormal coil conditions require different remedies.

Mechanical & electrical faults

Abnormal vibration, fan problems and control alarms need equipment-specific investigation.

02 / SCOPE & CONDITION

What we look at.

Area	What matters	Why it matters
An alarm code	Controller display and when the fault occurs	Record the exact code before a reset or power interruption.
Intermittent performance	Time, operating conditions and affected areas	Describe the pattern rather than only saying “not cold”.
Previous repairs	Replaced components and recurring symptoms	Provide available history to support diagnosis.

Work that can be included

Cooling and airflow problems
Drainage faults and water leakage
Motors, controls and electrical components
Refrigerant leakage investigation

Define the scope before work starts.

Parts, quantities, access, shutdowns and reinstatement are confirmed against your site and equipment. Additional defects or specialist works are discussed separately.

03 / HOW THE WORK PROGRESSES

A clear route from enquiry to completion.

01
Record the symptoms
Collect model information, photographs and operating history.
02
Diagnose the fault
Carry out checks appropriate to the installed equipment.
03
Agree the repair
Explain the proposed correction and any further uncertainty.
04
Test the outcome
Check operation after the agreed work and record observations.

04 / COMMON QUESTIONS

A little more clarity.

What information should I send?

Include the unit type, model, location, symptoms and any alarm code. Photos of the nameplate and affected area help us prepare for the assessment.

Does weak cooling mean the refrigerant needs topping up?

No. Several faults can produce similar symptoms. A refrigerant issue should be diagnosed, and any leak investigated, rather than assuming topping up is the answer.

Can you quote from a photograph?

Photos help us understand the equipment, but some faults require site testing before the scope can be confirmed.
