Your chiller is working fine. your thermostat may not me working or it might not get warm enough to kick it on. it doesnt run all the time.
However how do you know its not working? it only comes on when the spindle gets to a certain temp. you may have a cool running spindle, or you havent run it at high rpms.
one way to check is put a mark on the fan blade thats cools the condencer(its on the top) then check it at the end of the day to see if it moved. |
