Haier Appliances India Interview Questions, Process, and Tips

AC fridge models can have various problems, but most common ones include refrigerant leaks, faulty compressors, and thermostat issues.

• Refrigerant leaks can cause the AC fridge to not cool properly

• Faulty compressors can lead to loud noises or no cooling at all

• Thermostat issues can result in inconsistent temperature control

The salt problem is common in all models of A C fridge, causing issues with functionality.

• Salt buildup can lead to decreased cooling efficiency

• Regular cleaning and maintenance can help prevent salt buildup

• Using distilled water instead of tap water can reduce salt accumulation

Refrigerant is a substance used in a heat pump or refrigeration cycle to transfer heat between the indoors and outdoors.

• Refrigerant absorbs heat from the indoor air and releases it outside

• It changes from a liquid to a gas and back again in the refrigeration cycle

• Common refrigerants include R-410A, R-134a, and R-22

• Refrigerants should be handled carefully due to their potential environmental impact

PLC stands for Programmable Logic Controller, used in industrial automation to control machinery and processes.

• PLC is a digital computer used to automate electromechanical processes.

• It uses a programmable memory to store instructions and execute specific functions.

• PLCs are commonly used in manufacturing plants, assembly lines, and other industrial settings.

• They can be programmed using ladder logic, function block diagr...read more

MTTR stands for Mean Time To Repair and MTBF stands for Mean Time Between Failures.

• MTTR is the average time taken to repair a failed component or system.

• MTBF is the average time between failures of a component or system.

• MTTR is usually measured in hours or days, while MTBF is also measured in hours or days.

• MTTR is an important metric for assessing maintenance efficiency, while MTBF is used to predict the reliability of...read more
