Details for ST-007-11 York Affinity Packaged Defrost

Property Value
Name: ST-007-11 York Affinity Packaged Defrost
Description:

We had a few reports this past winter of the units listed above with noise issues entering and exiting defrost mode.  A change had previously been made to pin # 4 of the defrost control listed above which allowed to initiate at 26 degrees and terminate at 55 degrees, which resolved issues with the coil not completely defrosting.  At that time, the logic in the board was updated to cycle the compressor off 30 seconds upon an initiation of defrost, and 30 seconds upon a completion of the defrost period, eliminating the possibility of noise issues.  The compressor shutdown function is only active on pin #4.
