    Smile Has any one else had freeze up issues with GE Zoneline PTACS

    We service a hotel that has 136 GE Zoneline M/N AZ38H12EACM1
    the units are heat pumps

    They constantly freeze up. The coils are not that dirty, we see no signs of oil indictating a leak. I wanted to see if some one else has run into this?
    Thank you for your help
