I just had a new coil placed with a factory installed txv. I was wondering what signs a homeowner might notice if the txv was not functioning properly. I saw on another post that when brazing the lines in, that the sensing bulb should be protected. I do not know if the sensing bulb was near the brazed joint but the installer did not put a wet rag or shield between the txv and his torch.
The new coil is a Amer Std TXCO65S3HPCO. The condensor is Allegiance 12 2A7A2048A1000AA. Is the sensing bulb or any other component that is heat sensitive near where the lines are brazed?
