Can the cooktop of an electric range be slightly lower than countertop or does this pose a problem?

It is not recommended to have the cooktop of an electric range lower than the countertop. This can create several issues, including:

1. Safety hazard: A cooktop that is lower than the countertop presents a safety hazard. When hot pots or pans are placed on the cooktop, they may come into contact with the countertop and cause burns or other injuries, especially to children.

2. Countertop damage: The heat from the cooktop can damage the countertop material, especially if it's made of heat-sensitive materials such as laminate or wood.

3. Difficulty in cleaning: It can be challenging to clean the area between the cooktop and the countertop, which may lead to grease and food buildup.

To ensure safety and practicality, it's best to have the cooktop installed at the same level as the countertop or slightly above it.
