Hey friends!

Here is the deal.

I am troubleshooting my A/C system. I have gone through the work flow and I am down to the last item, the FIELD COIL.

The resistance is out of range (4.2Ohms), but I tested it at higher than 68 degrees. Is that relevant?

2ndly, if I turn everything on and lightly touch the pulley end of the compressor, it will engage, get cold, and run fine, until it cycles off and then I would have to do it again.

Does this sound like a problem adjusting the plate would fix, or is it because the magnetic coil is not working properly?

Thank you in advance!

 

Do this:

 

Done. The armature plate is bent. It's within spec on one side, but the gap grows larger as it goes around.

I guess replacement is in order. Do I need to do the whole clutch kit, or will I be OK just replacing the armature plate?

Thank you

 

My recommendation is to buy the clutch set (pulley, shim, snap ring, armature plate).
