No, you should not plug a 3-prong stove into a 4-prong outlet without proper modifications.
The reason for this is that a 4-prong outlet is designed to provide an additional grounding connection for safety purposes. The fourth prong on the outlet is a dedicated grounding wire, which helps protect against electrical shocks and provides a path for excess electrical current in the event of a fault.
On the other hand, a 3-prong stove typically uses two hot wires and a neutral wire but lacks a dedicated grounding wire. Connecting a 3-prong stove to a 4-prong outlet without modifications would leave the stove without a proper grounding connection, which can be unsafe and increase the risk of electrical hazards.
To ensure safety and compliance with electrical codes, it is recommended to either replace the 3-prong cord on the stove with a 4-prong cord or use a properly installed and grounded adapter. It is best to consult with a licensed electrician to assess the situation and make any necessary modifications or installations to ensure the safe operation of your stove.
