If it's making noise, and is on the exterior of the AC unit, it is likely not the condenser motor itself, but a separate fan motor and/or its bearings making that noise, as shown in the circuit diagram. This makes it much easier to fix, since a condenser compressor motor is part of a sealed system that requires specialized high-vacuum equipment to service. ...

if you have a clamp meter you can check the current draw of the compressor. A too high current indicates either a stalled compressor or the compressor spinning freely not doing any compressing. It is also possible that an internal part of the compressor failed which would also need replacement of the compressor. Replacing a compressor requires both ...

I tried to find a 1" totalizer flow meter for $40 - no luck. (I could buy one for around $115.) I tried to find an analog clock in the house - no luck. I ended up buying an inexpensive 250V AC hour meter and small plastic project box. Both for about $21. I forced the well pump on and heard the gizmo "whirring". It had incremented about 0.05 ...

As for design, for example, could I use a 120v meter (perhaps they are cheaper?) and just go across a hot and neutral? Also, it would be great to find an inductive meter because this would increase the safety factor and installation ease. Not if you want the meter to stop when the pump stops! (assuming a single pole switch) do you even have a neutral at ...
