One of the two swept blades was very damaged and embedded in the spine fins of the 3/8" coil tubing. Fan stopped after an hour, and it's really hot to the touch. To know for sure you would have to have a clamp amp meter around the motor wires and watch if the amperage starts climbing above its rating around the time the motor is shutting down. Our central A.C. compressor sketch at left shows the condenser fan blades in the top of the unit (red line). There will also be a few wires connected to the top of the capacitor. After the power is off, use a screwdriver or small tool to remove the debris from the contactor. Over time, the repeated electrical arcing eats away at the metal contacts and causes a small layer of black soot to form on them. My guess is no low speed, but we need to know all circumstances in which that speed is used to assure dropping it is ok. Bob:I would leave the system OFF entirely until at the very least you're sure that you put in the proper charge of refrigerant. Fan Only Switch.
