[C320-list] Air-conditioning problem

[Jane & Ken]

I agree with the previous answers----if the pump was //has been working fine, then the likely problem is some blockage.  If after trying the blockage removal without success, I would remove the pump and check the bearings for some foreign matter in them or at least clean them with WD-40 and then lubricate them with a good (I use slick 50) lubricant and reinstall.
  Basically, if the pump runs, then it should not heat up and cause a system shutdown.

  I'll bet the fish just love the Drano. I used bleach and let it set 
in the system for a little bit the turned it back on and watched the 
crud fly out the output. If you have a March pump it should not 
overheat in any location so you probably have a restriction on the 
inlet. Have you noticed a reduced out flow?
