If they came with the house, then no. You didn't pay for them, or there was a clause in your contract that said you are buying the house for the selling price, and you are buying the contents for $1. (This is typical.). If you didn't pay for the appliances, you can't depreciate them.
[Edit, since starting to write my answer, I see there is another answer that you can depreciate the appliances if they "came with the house" but you must reduce your basis in the house. I think that both my answer and that answer are acceptable alternatives.]
If you bought them separately, you can list them as separate assets for depreciation, so you recover their costs faster. BUT, the basis for depreciation is either the price you paid, or the fair market value when placed in service as a rental. So you need to list them at their present (used) value.
Lastly, I am not a rental expert, but @Carl is, and he will tell you that (for various reasons) you should want to minimize your depreciation, not maximize it. So it might be better to just include the appliances as part of the overall value of the house.
