The capacitor went out. Cost me $100.
That is a hell of a deal. You could have saved about $75 doing it yourself but $100 for an A/C guy is a great price.

How do you replace it?
they store an electrical charge just like a taser
they zap you good like grabbing a sparkplug wire but it doesnt have enough amps in it to hurt you
turn off power to unit at disconnect by the unit
just about everything on an a/c unit is put on and removed with a 1/4" or 5/16" nut driver so these are good to keep in your tool box
carefully remove the cover for electrical box of unit ------ WATCH OUT FOR A NEST OF WASPS ATTACKING YOU
use a screwdriver to touch across the terminal connections to discharge the stored voltage and then its safe. just do both sides because both sides will store energy.
then its use needle nose to unplug the wires after taking a picture so you put them back on the same way.
the capacitor is usually held in place with just a metal strap holding it.

Mine has two capacitors. One is the 70 microfarad and one is 7.5 uf. The 70 went out on mine early this year and I got lucky at a warehouse in town and found the one I needed. Came home and ordered another set for when they go out again.

How can you tell if the capacitor is the issue?

Happened to me a week or two ago and my wife said it’s just hot out and the AC can’t keep up. It was 99 in my fricking office Called the AC company and they fixed it in a couple days once the part came in.
What’s crazy is when my daughter came in from school I warned it was super hot upstairs so she might want to stay downstairs. She went up anyway! When my AC guy got here, he had me go upstairs and turn the unit back on at the thermostat. I looked and it was reading 86 degrees up there by then. After I turned it back on I knocked on her door to check on her, she’s laying on her bed with her pug doing homework… and she’s wearing a freaking SWEATSHIRT! Yeah, she had her ceiling fan on, but a sweatshirt when the AC is out?!?
I’ll never understand the female side of our species.

That’s good info. Tells me I’ll still call my AC guy next time.

This may be the most impressive thread yet on Tiger Droppings. Thank you all.

Hell…we still can’t figure out what’s going on with mine. Froze up last Friday night…service guy came Sat morning and we replaced the main filter (that was pretty dirty). Checked everything…fine. Set it for 75 and it ran well.
Ran through the weekend and froze again yesterday afternoon. After it thawed I turned it back in to 75 and it started freezing again….bumped it to 79 and it ran fine through today. Service guy came out again…refrigerant, air flow, coils, all good. He said they can’t find anything wrong with it and to not set it for more than 20 degrees from outside temp.
So when it’s 102 this weekend I’m supposed to set my AC to 82? WTF?

Freezing up is generally a sign of low freon. Get a different tech to check it and make sure he validates the pressure readings against a temperature vs pressure chart.

Do the capacitor numbers really have to match or will anything close work?
Posted on 8/22/23 at 5:04 pm to MorbidTheClown
I got no air when my capacitor went out so I’m thinking something froze up as well

We’ve had two now that both confirmed the refrigerant is good. The owner of the company is a long time family friend of my FIL and we’ve worked with them for 15+ yrs. They do a ton of residential and commercial so surely to God they know how to check it.
If it craps out again we’re calling the owner.

I have a reminder on my Outlook calendar to replace my filters monthly. I also have a reminder to call my AC guy every spring to service my units. These damned things cost too much to not keep them maintained.

Good for you.

I know nothing about AC but I’m guessing maybe the compressor froze up as well? With my issue today on the capacitor, it still blew air. It was just hot air.

We change ours religiously but not every month. We also have a service agreement so they’re out twice a year checking on things. The unit is only 2 years old too and we never had any problems.

just from memmory i think its within 5-6% is all it can be
so "maybe" a 65uf will work in place of a 70uf but i wouldnt risk it.
if its not right, even if it works, the motor may go bad after a few months
