Bare with me on the long story; the question is at the end if you want to skip through it, lol
Yesterday our AC stopped working. So we called up a friend of ours that does AC work, he looked at the unit ouside, and found a fried wire attached to one of the leads on the capacitor. It was a super thin wire to begin with, so once he saw it he wasn't all surprised.
So he replace the one wire with a new thicker wire, and viola, AC works again!
for about 2 hours...
then it stopped completely again
Well, lucky for us, our buddy that helped us had plans to go out of town for father's day, and within that two hours, he was on the road and headed to south Florida... so he couldn't make it back out, and isn't returning until Monday afternoon...
So we dealt with the heat Saturday night, and most of Sunday morning, then I got adventurous (and sick of the heat) and decided to peek inside the unit that's outside, and see if maybe another wire fried... I mean comon, I can replace a stupid wire if that's all that it is...
So I killed the power to it, pulled the panel off, and low and behold, one of the terminals on the capcitor is pretty much melted off, lol. The plastic around it was barely hanging on. The wires looked fine, but the cap definately looked shot.
So we searched around locally (there's not a hole lot of stores that sales these open on Father's Day... go figure), and no body carried them... Lowe's, Home Depot, Ace hardware, etc...
So, I'm going to pick one up tomorrow, probably from Grainger, and I'm having a hard time locating a round dual capacitor with the exact same specs as this one
I know the 370 is the volt rating, and it's perfectly acceptable to replace it with one of a higher rated voltage.
But it's the MFD ratings that I'm having a hard time matching. Although I am finding them with the first number of 50, it's the second number of 3 that I cannot find ANY of...
I guess in the end, my question really is:
Can I replace a 50/3/370 dual cap with say, a 50/7.5/370(or 440) dual cap? Or maybe even with both numbers being higher, like a 55/5 or 60/5? Would that cause harm to the system? Would it actually make it more "robust" so to speak (would it more or less be an upgrade).
I know when it comes to electrical, it's NEVER a good idea to replace something with a LOWER rated number that what's already there, so I know I can't stick in a 25/5 or something, lol.
