No 24V from T2(Defrost board) so contactor won't engage

So Contactor is working fine. I checked it bypassing 24V.

T1 and T2 is not getting 24V. What could be the problem?

and also if I manually engage Contactor by pushing it, the Fan does not work.. Is it because of bad capacitor?

If you have 24vac on Y but 0 on T1 then the pressure switch is open. You need to call a HVAC tech.

The contactor is for the compressor, not the fan as the board controls that.
