Abstract :
The refurbishment and restoration of an 80-liter water cooler is a practical approach to extend the lifespan of
existing equipment while reducing cost and material waste. This study focuses on identifying faults, repairing damaged
components. and restoring the system to efficient working condition. The initial stage involved a detailed inspection to assess
the physical and functional condition of the water cooler, during which key issues such as a faulty fan motor, damaged relay,
compressor overload problems, rusted base sheet, low refrigerant levels, and a malfunctioning thermostat were identified.
Following the inspection, defective components were carefully dismantled and either repaired or replaced with standard
parts. Gas charging was carried out to restore proper cooling performance, and all electrical and mechanical connections
were tested to ensure safety and reliability. The work was done in a way that reduces cost, uses old parts when possible, and
follows proper basic maintenance. The results demonstrated a significant improvement in cooling efficiency and overall
performance of the water cooler after restoration. The project also provides practial insights into common faults and repair
techniques applicable to similar cooling systems.
