Workshop compressor capacitor

[DeeJay]

My compressor needs a "hand spin" to get going. Apparently, there are start & run capacitors & I need to replace the start one.
Which one would it be? Google is no help.

Pretty sure it's the bottom one with the higher Microfarad number, but at around $50 each ( last time I did one ) why not do both? I got it from a motor place in the Gully, but I suppose Dandy would be closer for you.

^^^ What he said. And if the start cap is duff, the run probably isn't far behind.

Very easy to test them for anyone with the right meter , literally a 1 min job .
Could also be the centrifugal switch or the start winding .
Quite often when they go they split & smell bad .

G'day All,

"Rockby Electronic Components" Melbourne has motor start/ run capacitors for a few dollars. This is the link to the page:

They do mail order as well and if your value not listed give them a call to check stock or where to buy at good price.

Both Capacitors can be purchased from Wiltronics Melbourne:

Wow. Another reason for me to like that mine is 3 phase.

There was a house burned to the ground last week in Melbourne somewhere where the fire started in the evap cooler on the roof.

Not the first time either.

I didn’t think it had been hot enough yet for AC this year in Melbourne - I installed new AC in the house 2 years ago along with really good insulation - I could count on one hand how often we’ve used it since, but I am glad it’s there for when it’s needed.

I think Saturday may be a day it gets a run based on the current forecast.

Never had it. Admittedly, living up here amongst the trees helps.

Reason I have 3 phase to the house is that there was a dead a/c system here when we bought, but neither of us wanted to replace it. Of course, new builds are designed with a/c as standard. I can't imagine my son's house in summer without it.

It's predicted to reach 37° here on Sat, which is really just quite warm. Probably a bit higher out your way, Gav.

Plenty hot enough and anything over 25 it goes on as my wife thinks its unbearable, our house is quite hot though.
Previous owners had no insulation for the 20 years before we bought it, i put some in but once the AC ducting went in it will take a contortionist to get any more in.
