I have a Pentair heat pump, Sta-Rite pool pump and air blower on the spa for inground pool. The spa air blower is hot, but no electricity to heat pump or pool pump. The timer is a 24 hour Intermatic Mechanical Timer. One day ago everything worked OK today nothing came on. Pool and spa lights are OK- they are on a different circuit. Any suggestions on what to look for would be appreciated. Thanks.:confused:
