Your right GreenPants someone put 20amp motor fuses (Dual Element)and some coils did burn. The correct fuses for this controller is (3)5amp one-time, as per manufacturer specs, without retiring cam motor in control circuit. At 5 amps the fuses also provide overload protection (125% of rated load) and overcurrent protection. I have experienced the overload protection working properly. Correct fuses protect equipment and save time and money.
