Hello.
I have a question about my 5HP Sullair 2 stage compressor. I have owned it since about 1980 and it has performed flawlessly until recently. The last few times I turned it on it started slowly. Once it came up to speed it ran like it always did but the next time I started it up it started even slower. I don't want to burn up the motor, which is a Baldor 5HP, 1725rpm brute of a motor.
I suspect it is a bad starter capacitor. I pulled the cover with the capacitors in it off and the caps look fine, no leakage or anything. It has 3 capacitors on it.
Is there a simple way to check them with an ohm meter? I recall checking some other smaller condensers with a meter by reversing the leads and seeing if the meter slowly drops.
Any ideas would be much appreciated.
Thanks,
Brian
