Hi,

It's fuse 17 in the central junction box. See pic 1 below. If you look at pic 2, it shows the fuse you are looking for. When you check the fuse, also confirm there is power to and from it.

Here is a link you may find helpful:

Let me know if this helps or if you have other questions.

Take care,
