Can you stack a convection oven on a microwave oven?

It is possible to stack appliances as suggested, but there is a caution. Here it is. Both units generate heat, and the microwave actually has air moving through it and exiting at an elevated temperature. The installation instructions for both machines must be reviewed and sufficient space made betweenand around both machines (including behind them) for the appliances to operate without inordinate heating. If the instructions are not clear and/or your have doubts, you will be wise to consult an appliance technical professional. Note that all these machines have definitive installation instructions. Should you ignore warnings and "wing it" with the installation, you risk (at minimum) damaging the unit or units. Additionally, a fire can result, and property damage could be considerable. Lastly, people die ever year from the affects of smoke inhalation because they are trapped (or sleeping) inside a burning structure. You may kill yourself and/or a family member, or a friend or relative who is staying over.
