power went out while furnace was running on our Stylecrest Revolv furnace and now the limit switch error code is on. Where exactly are the limit switches on furnace

Here is the corporate link. You didn't give us much to go on so maybe you can find it under your model. There are many, gas and electric. They would have different limit switches.
