Armstrong TR25-10 help needed

[ventport]

The compressor on my Armstrong AC worked for a while and it blew cold. Now The compressor just hums. From what I have read, I may need new start and/or run capacitors. Does anyone know the MFD values of the 2 capacitors so I can buy them?

You would be better off checking the values of your existing capacitors. Both the compressor and fan motor have been replaced in my Armstrong, and each required a different value capacitor than the original equipment.

Your unit may not be able to use the capacitors mentioned by others.
