Why doesn't my Ameristar Air conditioning unit run?
- SSamantha ChenAug 8, 2025
There are a couple of reasons why your Ameristar air conditioning unit might not be running. First, the overload protection switch may be delaying the unit start-up for three minutes. If you detect a malfunction, immediately turn off the main power switch. Second, the unit may be in standby for one minute. In this case, contact your servicing or installing dealer.
