Looks like someone added a ground strap to the controller aluminum case? Not original equipment (obviously). Not sure why - pehaps they were using an ungrounded AC outlet and wanted to add a ground wire?

Hi @TonyP - yes the motor turns by hand quite smoothly. I don't think these motors have a start cap, as per my previous comment. My guess is that it is a Split Phase Induction motor. This looks like a good description: https://mrelectrician.tv/electric-motor-diagrams/ My motor coil DC resistances are 1 ohm for the main coil (Blue to yellow wires) and 5 ohms for the starting coil (black to yellow wires). No idea what these are supposed to be on a good motor. Yuri

I found a parts catalogue online in an inconvenient "page image" format, so downloaded the pages and put them in a Word file. Here is a PDF of it. Hope it works easier for some... Yuri Softub_parts_catalog_2010-07-15.pdf

Hi all. I have a "new" used softub that has motor issues (the price was right!). It just buzzes and doesn't turn - so i suspected starting capacitor issues. I have the back off the motor, and the centrifugal switch seems OK. The wiring from the switch goes directly to the starting winding, and I don't see a capacitor anywhere in that area. There is Klixon CEJ18EM motor protection device mounted on the back inside of the motor, but nothing else. The motor is a 1HP model S55CXNPH-7249. I also don't see what I would recognize as a starting cap in the photos above by Samos12. So my question is: has anyone found it's location in this style of motor? The alternative is that is doesn't have one. I found this reference online: https://www.quora.com/Does-every-single-phase-AC-motor-require-a-capacitor-to-run?share=1 Most small AC motors do not have a capacitor. Small induction motors do have a starting winding, But the phase shift is produced by using a smaller size wire with fewer turns. So the main winding has mainly an inductive impedance while the starting winding is mainly resistive. It has less starting torque than a capacitor start motor, but it is adequate for washing machines, dryers, and power tools. Any ideas? Thanks Yuri

I need one. Where are you located? I'm near Ottawa Canada. Let me know!
