Arcing on connection to cap on Trane A/C compressor

Mine is an old Canadian Westinghouse unit. from 1974. Other than having the gas checked about 18 years ago and having half a pound added, the only problem we've had was a bad thermostat connection (which was the real problem when I had the gas checked).

You're responding to the wrong poster but that's cool(no pun). ^_^

So, Mr. Knows the Answer. How many amps flow throuch such a cap?

That's a pretty big compressor. Back in 90, were scrolls available? Or maybe rotary? Or did you have to put in a newer piston unit?

I bet the energy bill went down.

Around 1990, I came across an very old Westinghouse condensing unit with a pancake compressor in it which appeared to be 1950's and it was still cooling alright ; they wanted me to replace it to avoid a sudden breakdown and to save on electricity . It was a 3 ton capacity but the physical dimensions were approx. 5' wide x 5' long x 5.5' high . It was so heavy i had to cut it up into 3 pieces .

Compared to the compressor being served?

There's a difference between selfish tech versus a customer service oriented tech. You are the finer of the two. The quality shows.

a two speed condenser fan. The only thing wrong with it was the fan quit working. Another tech told him he needed a new unit and wanted to install a cheap builders/contractor grade replacement condensing unit. I replaced the fan motor with a (not cheap) two speed motor and the old Carrier with the insulation blanket around the compressor hardly made a sound when the fan was running at low speed at night when the ambient temperature was low enough. The darn thing should run another 20 years without a problem. Yes, I know the new stuff is more efficient but the old guy didn't have thousands of dollars to shell out.

It will depend on the type of cap, and the voltage rating.... 35mfd caps come in voltage ratings from .5v to 50,000v.....

As far as the current handling capabilities of spade terminals, they are sufficient to run a 5 ton scroll compressor. They just need to be clean and tight. If the system is grossly over charged, it will cause the compressor shell to sweat... moisture gets into the terminals, that causes corrosion, that causes resistance, that causes heat, that causes the terminals to burn.

But......... these are things that you just haven't figured out yet, because its part of a complete system assesment, as opposed to just washing out the condenser coils.

I'm looking for a number, in amperes, please. Didn't think you knew.

what voltage??

How many voltages are provided for the outdoor unit of a residential Trane?

Still didn't think you knew.
