Yearly Reminder - Get Your Spare A/C Capacitor
Posted on 3/7/23 at 8:57 am

Just a reminder, if you do not have a spare A/C capacitor, you may want to pick one up. CrawDude recommends AmRad capacitors as they are American made.
I would also suggest having a spare relay/contactor for your unit.

Got mine back in October. Now, where I put them is another challenge.

What are the symptoms when either of these go bad?

A record hot summer day at the most inconvenient time.

Either the fan won’t be turning or the compressor won’t be running. Without a functional capacitor, a single phase motor is not able to run (except with some specific electronics).

I need to go ahead and do that. Is there any way to get specs off the old capacitor without disassembling the unit? Would it be in the literature that came with the unit?

I zoomed in on my capacitor and took several pictures. This made it easy to see what size capacitor I needed. I ordered mind from Amazon.
I put the capacitor in the utility room where I keep other spare parts.

And here's my yearly reminder:
CAPACITORS HOLD A CHARGE.
Learn how to discharge those suckers or potentially ride the lightning.

If you're like me, when you need it, you'll never be able to find it. :)

Guide me on how I figure out where to buy and what type?
Wife's uncle is a commercial HVAC guy so we usually call him up, orders the parts directly from an store off Coursey that only deals with commercial purchases, and he replaces while I pay cost and offer a nice bottle of bourbon for doing the work.
Would be nice to know what to buy so I can do the job on my own, especially so I don't have to worry about waiting extra days for the part to come in and I can have one on hand.

I would suggest it’s easier to be friends with a guy that owns an AC Business, but that’s just me.

This is EXTREMELY good advice! Same goes for an auto mechanic.

I go to church with one. He's helped me out several times. On the same day.

you'd be miserably hot in fricking february/march nowadays in louisiana if the capacitor failed on you

Ok let’s see if I can do the pictures right.
1. Have a multimeter with capacitance reading ability on it.
2. Discharge your capacitor. To do that turn the disconnect off on your condenser or air handler. Take a screwdriver and touch the prongs together.
3. Take a picture of how the wires are hooked up on it. Then take them off of the capacitor.
4. Touch the leads on your meter to the common prong and the fan prong then to common and herm prongs. Note the readings for each.
Notice the numbers on this capacitor is 45/5. The larger number is the microfarads for the compressor or HERM and the smaller number is the fan. It also has +5%. So take the numbers off of your reading from the meter and do the math and figure out if you’re outside that 5% tolerance. If so change the capacitor out.

You can use Titan HD, which are cheaper than Amrad and are also American made

Most experienced HVAC guys keep a few of those in their truck. Bad capacitors are that common of a problem.

I do commercial AC also. You don’t carry many parts at all and you run across very few capacitors because in commercial most units are 3 phase electrical

The company that I do business with always has a few in the truck.
ETA: They do a lot of residential in a rural area.
