In general, most modern refrigerators with built-in ice makers should start producing ice within the first 24 to 48 hours after being connected to a water supply. However, there are some factors to consider when assessing the situation:
Water supply: Ensure that the fridge is connected to a water supply with proper water pressure. Low water pressure can hinder the ice-making process.
Ice maker activation: Make sure the ice maker is turned on. Some refrigerators have a switch or button to activate the ice maker, and it's possible it was not enabled during installation.
Temperature settings: Check that the freezer temperature is set to an appropriate level. The temperature should be low enough to freeze the water but not too cold that it hinders the ice-making process.
Initial ice production: If the refrigerator is brand new, it may take some time to produce the first batch of ice. The ice maker needs to cycle and fill with water before it can start producing ice cubes.
Air in the water line: If the refrigerator has a water dispenser, it's possible that air may be trapped in the water line, initially preventing the ice maker from working. Running the water dispenser for a few minutes can help purge any air from the line.
If you've checked all the above factors, and your refrigerator still isn't producing ice after 48 hours, there might be an issue with the ice maker itself or the water supply to the fridge. In such cases, it's best to consult the refrigerator's user manual or contact the manufacturer's customer support for troubleshooting assistance or potential repairs under warranty.
