B&G Series 60

Specifically, the 613S.

I had a service call at a large apartment building today for no heat. Both pumps were missing their start capacitors and nobody knew where they went.

I called around and apparently there isn't even a part number for the caps? No chance that anyone knew the specs of the caps. They're saying the complete motor and/or pump must be replaced? Does anyone have any information on Series 60 start capacitors?

I took a somewhat educated, WAG as to the cap size and did a 2 second run on each pump and they worked. I did that only to verify that there's a decent chance the pump and bearing assembly are good.

Anyone?

    What HP? You may be able to reference a compressor.

    Most start caps are taken out of the circuit by a potential relay, this one taken out by a centrifugal switch although that shouldn't matter. The maintenance men said they had no idea what happened to the capacitors. Really? My guess is someone robbed Peter to pay Paul.

    Part number is M75065 and it looks to be 40mfd. I would call a rep to confirm, though.

    Joe - I appreciate the help. I did call the local rep. They said no part number and no specs. I will follow up based on what you shared. If you have a parts list that includes the capacitor, please email it to me. Thanks again.

    Here in the DC area we have a Co. called Southern Utilities and I bet they know.

    Stephen, looked thru some of my stuff and found a parts list for the series 60 b&g it shows the start cap part number Joe mentioned.

    I have 2 series 60's in use they are 120 vac 1/2 HP though. I can look tomorrow what start cap they use. As long as it starts and the centrifugal switch disconnects it from the windings. It is only in use for less than a second. If it stays energized sometimes they explode, ( Just ask how I know).

    Call a shop that rewinds motors. They will be able to tell you.

    @Joe and Abracadabra - I forwarded that part# to my guy at my supply house last night and he's thinking that it's still a valid number. And, it is a run capacitor on that motor. The last few Series 60's (617S) I worked on used start caps. This one is actually a PSC motor.
    A huge thanks for the assist.
