If it is dead, it wont discharge. but yes try shorting it to be sure.Is it necessary to discharge the old capacitor in performing the change?
I seem to remember some danger of a "shock" if that step was not taken.
Yep. I learned to keep spares for the well pump and the AC.$30 cap, gonna buy 2 so I have a spare.
Will keep an eye on the fan motor.

Last night, I noticed warm air blowing from our system.
I went outside, and the fan on the main unit was not on, and things were getting pretty hot to the touch.
I turned the system off, waited about 30 minutes, then powered it back on again.
The fan didn’t move, so I prodded it with a twig. I felt some resistance, but it quickly ramped up to speed and things seem to be working normally.
I’ve gone to check on it several times, and the fan is activating.
I figure the fan motor may be on its way out.
Google-fu suggests I should replace the motor and the starting capacitor, but before I start replacing parts, I was hoping y’all may have some insight?

It's easier than automotive repairs.Well, new cap, and about 30 mins ago the unit did the same thing.
When the unit cycled on, I could see the fan try to move, but it wouldn’t.
Got it going again by poking it with another twig.
Looks like I’m replacing a fan tomorrow.

You might try squirting some WD-40 down the spindle of the fan motor to see if you can get something to lube the bearings. You don't want to do that to a motor that is working, but since you're looking to replace it any way, try it out.Well, new cap, and about 30 mins ago the unit did the same thing.

pronstar,
OFF TOPIC but you may be interested in knowing that I'm likely about to SELF-import a one owner/low mileage/rust-FREE "black market" 1985 Mercedes W123 gas sedan with manual 5-speed from Europe.
Straight six engine, maroon/maroon, manual sun-roof, manual windows, fabric interior & manual "everything else", too.
(That 4-dr sedan will likely outlast me, too, as the manual/manual/Euro-spec W123 sedans are TANKS.)
yours, satx
You’re right...I’m interested!
The W123 and subsequent W124 models are considered by many to be “peak automobiles” and a great tribute to the engineering and reliability MB used to put into their cars.
The base Euro-spec cars were definitely the best.
She sounds like a real winner

pronstar,
ALL that I plan to do to the W123 saloon when it arrives, other than routine maintenance, is replace the "somewhat worn" (IF they really ARE "showing wear") fabric seats with maroon LEATHER seats out of a low mileage/"totaled" 300D, that I found by accident near Austin.
I also will likely replace the original Am/FM radio with a NICE (maybe SONY) AM/FM/CD stereo.
(When I was stationed in BRD, I had a "manual everything" W123 saloon.)
yours, satx
Are those seats leather or MB Tex (vinyl)?
Most MB’s from that era had MB Tex, which I actually prefer. It lasts and looks great decades later

Back on topic.
Back in the old days, fan motors had oil ports. A little oil every spring and they fan bearings lasted a long time.
Don't think any today come with that. Most of the motors are coming out of China now and are complete junk.
Ten years is not bad.Yeah this one looks sealed.
Based on the numbers I was told it’s likely original to the unit, so it’s probably 10-ish years old.
