Start first with fixing the melted fuse and make sure the connection is tight or it will melt on you again. Check your pressure as well and post back and we can work from there.
From looking at you reading your pressure are to high, inmost cases this usually means the system is either overcharged or the compressor is failing. I would start first with evacuating the system and recovering the Freon and then recharge it with the correct amount (30 ounces) . Normal pressures need to be right at 35 to 40 PSI on the low side and right at 200 to 225 PSI on the high side.
The cycling switch works off of low pressure to shut the compressor off when the system is low. If you replace these parts , be sure to do a system flush at the same time. Please take a moment to rate my service so I can get credit for my time, the question remains open for follow up even after doing so, all you need to do is return to this question if need be.Thank you again.
You pressure are reading a bit on the high side, has the system been over charged?
Well I think I would start with doing a system recovery and evacuate and recharge making sure to get the proper amount and see if that solves the problem.
Well form you pressure reading the only thing im seeing is they are on the high side and that can and does affect compressor and AC performance. Under normal circumstances that the procedure any shop would take to get this diagnosed .
Its possible you may have a bad low pressure cycling switch . It may be worth a shot at replacing it.
If the low side is going into a vacuum then yes that indicates you have a restriction and in most cases that would be a failing expansion valve. If you end up replacing it, I would flush the system as well.
It would not hurt to change the dryer but I would stay away from the Sub Zero refrigerant, it has a very bad track record. Stay with R 134 for the best results.
I would have to agree as long as it has the proper charge.
You may but if the valve is bad and has debris in it then a flush would be the correct thing to do. If there is nothing in the old valve you may be okay
It a 50/50 chance its okay, If it where me, I would replace it just so I did not have to do it over again, its your call.
