Exclamation A/C Blower Issue

I have split system (2 years old). I noticed that the a/c was turning on , but the vents had no air coming out. I check system out side and condenser blower was running fine, but lines are frezzing up. I check inside blower and the blower is trying to move, seems to be jerking forward and stopping and then trying again. I check to see if anything blocking, nothing. When system is off blower manually moves freely.

When Ipurchased this house from the builder, I told him the a/c unit and pad was sinking. It is to the point that the you cant even see the pad anymore and when it rains hard the unit does flood. Not sure if that has cause my current issue

Any help would be great

Most air handler blowers are permanent split-capacitor motors.

That run capacitor could be bad.
By the way, capacitors can hold a powerful shock after power is off.

Put a screw driver across the terminals before touching them.

Check all the wiring for poor connections.

The motor could be going out.

There are many checks a Tech can do that you shouldn't take chances getting shocked messing with.

If the motor rocks it sounds as if you have a variable speed motor with a bad motor module.
