In auto mode, at correct program time, a single click is heard, filter pump light at outdoor and indoor panels turn on and stay lighted, but filter pump does not turn on. In service mode, filter pump can be turned on manually at pump and will then remain on when returned to auto mode. In auto mode, filter pump does not turn off at end of program, but can be turned off manually at pump. Please advise if this indicates the power center requires repair, and if so, the cost and turn-around time. Thank you.
