Trane ac error code ec

 

Error code EC on a Trane air conditioning unit typically indicates a communication problem between the indoor and outdoor units. This can be caused by various issues, such as faulty wiring, a failed control board, or a problem with the communication protocol itself.

To troubleshoot this error, you should check the wiring between the indoor and outdoor units to ensure that all connections are tight and secure. You should also check the control board on both units to ensure that it is functioning properly and that there are no visible signs of damage or corrosion.

If these basic checks do not resolve the issue, it may be necessary to call a professional HVAC technician to diagnose and repair the problem. They will have the tools and expertise needed to identify the root cause of the communication issue and take the necessary steps to resolve it.
