No, it is not recommended to keep or place a stabilizer on top of the refrigerator body. The top of the refrigerator is not designed or intended to support additional weight, and placing a stabilizer or any other heavy object on top of it can potentially damage the refrigerator or pose a safety risk.
Stabilizers are generally used to provide support and stability to appliances by being placed under them. They are designed to distribute the weight evenly and prevent appliances from tipping or vibrating excessively. Placing a stabilizer on top of the refrigerator can cause an uneven distribution of weight and potentially disrupt the refrigerator's balance.
If you require additional stability for your refrigerator, it is best to use a stabilizer or leveling feet specifically designed for that purpose. These should be installed according to the manufacturer's instructions and placed underneath the refrigerator, not on top of it.
