What should be done after servicing an appliance that contains refrigerant?

After servicing an appliance that contains refrigerant, it is essential to check for leaks and document the service. This is critical for several reasons. First, ensuring that the system does not have leaks is vital for safety and environmental reasons, as refrigerants can be harmful to both the environment and human health. Leaks can lead to refrigerant loss, which diminishes the efficiency of the appliance and may impair its functionality.

Documenting the service performed is also important because it creates a record of the maintenance for future reference, which can be beneficial in tracking the appliance's service history and identifying any recurring issues. This documentation can also help in compliance with regulations that require record-keeping of refrigerant management.

The other options, while potentially beneficial in certain contexts, do not directly address the immediate post-servicing requirements for appliances containing refrigerants. For example, disconnecting the power supply is a precaution taken during repair, but it does not relate to ensuring the integrity of the refrigerant system after service. Similarly, sealing and storing the appliance might be necessary in specific situations but does not engage with the essential need for leak checks and documentation. Cleaning the appliance, while important for maintenance, does not address the crucial post-servicing steps necessary for ensuring safety and performance
