All,
On the work Bench today are two Compressors from my past that have been sitting in corner of the Pole Barn for years.
The Craftsman one turned out to be a Pressure Switch Replacement.
The other one, a Harbor Freight stand up Oil Filled unit, from the Mid to late 2000's(prior to 2010).
Anyways, from memory this unit was having issue starting up. I replaced the oil in the unit back and I also confirmed the pressure switch was ok but I was getting to the point of turning it on and off to get it start/run. Finally it just stopped starting. I threw it in the corner of garage until we moved to consider just utilizing the 30 Gallon Tank for other endeavors. The Oil Filler motor easily turns by hand and still does even today.
So I started digging in to the unit today to find the below (see attached image)
Believe it or not there is no burnt smell in the windings or even coming from the capacitor. There is a slight smell to the white capacitor but its not a burnt smell. I am going to do a ohm reading across the Windings (seen a couple you tube videos describing the process to confirm something else is not awry.
Looks like the white one (70uF) may have been the Starting Capacitor one based on the issue experienced and the mess it is now? The Black (80uF) the running one? But I always thought Running Capacitors were always smaller Farad-wise?
My questions are around the replacement approach. Both will be replaced. The black one actually has a popped plastic top (hard to see). It appears that many of the possible replacements (Farad-wise) are 370 or 440 Volts and the originals were 250 Volts.
I have been told in the past (smaller capacitors) that you can increase a voltage on a Capacitor without much harm assuming the Farads are the same. Is this true on these larger Capacitors?
Are there any brands that are better than others for these larger Capacitors? The originals were AOLEI.
I have looked at EBay, Amazon, and Grainger are there any other suggested locations?
Thanks for the help,
Chris
