Heavy duty AC fuse difficult to remove

[BSdetect]

Our AC has a huge looking fuse up in the attic for the air handler device. Seems bigger than the fuse outside on the compressor.

I could not remove it by pulling - its also in a slightly awkward position so is hard to grab with leverage.

I'm reluctant to put too much pressure by pulling but wonder if this is normally required or is there some tool for this.

There is a smaller looking fuse outside the house for the compressor and that comes out easily.

The company that installed the system has not called back and we need to get some heat going here.

There might be a small 5 amp fuse inside the air handler and I will try to see if that has blown.

I read that if I replace that and it blows again then it may be the transformer that is faulty.
