I have a package unit outside. The ac stopped working. TStat seems to be working fine.
In the past, I replaced the control board 2 years ago, compressor fan motor 3 years ago along with all 3 capacitors.
There is no fan in fan or auto modes. The squirrel cage spins nicely by hand and checked power, it is there at the motor with the tstat in fan mode, but no spin. Power not flowing through the contactor ( not plunged in).
I replaced the transformer, because that is often the problem with no fan? Replaced the contactor because the resistance was less than 10 ohms between the low voltage sides? No change
The control board has a 5amp fuse which I reseated and checked.
There is no power between R and C. Am I looking at a board change again? Thanks in advance.
