Heavy duty AC fuse difficult to remove

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.

I don't know anything about air conditioners or fuses for them, but my husband is an electrician and he says to make sure all the power is disconnected before you try to pull that fuse. A friend of ours, who is also an electrician and should have known better, did that very thing a few months ago and it flashed. He lost almost all the skin on his hands and is lucky that's all that happened.

The breaker is off until I get the fuse out.

So no danger from that.

Check with a voltmeter before grabbing stuff.

all the numbers for that matter ,than call a local ac supply company and get the information you need to proceed. You can type into search the name/make and model number of your unit .Than refine your search to the problem area. Most likely you will end up viewing a youtube how to video . Also you can call or contact the manufacturer on that problem, they have a web page and no doubt have chat service during work hours to assist in costumer support. Customer service,by phone will no doubt put you in contact with a specialist . The specialist can in-turn run you through the trouble shooting process. There is plenty of good information to come your way by contacting the right people in the right places. My rec. ,contact the manufacturer because they are all about customer satisfaction. And you need to know what you are doing in what ever you are going to do and if you don't, you may do better by staying out of there.

Turns out that the fuse had melted partly and that made it really hard to pull out.
