Sounds like we have a blower issue causing the error. What is complete model on unit?
I believe the 9c has a variable speed blower.If so it will have two seperate groups of wires going to motor as it I high voltage powered but low or dc voltage controlled.These require a special diagnostic tool to troubleshoot. Can you look and tell me if it is a variable speed or just a standard psc motor?
The problem is going to be one of two things. One could be the control board is not sending signal to motor and the other which is most common is a defective controller on the motor.
The tool for testing costs about 100 bucks. You can see it at link below:
If you have the tool or wish to obtain it, I will be happy to assist you in detemining if issue is with control board or motor.
If this is something you want to troubleshoot and have or can obtain the test tool,let me know.Otherwise you will need an onsite tech to troubleshoot to determine if issue is motor controller or board.

The most common cause is the bell control on the end of the motor .They are known to fail on these units.
Hopefully this will be cobvered by warranty as the motor with bell is about 800 bucks wholesale.If you can give me serial number I will be glad t check on warranty status for you.
The limit is not going to be the culprit but rather the result of the motor failure.
You most likely have 120v to motor as that is constant. Issue will most likely be controller on motor or the board, but usually the controller on motor.
