Our page top photo of a compressor/condenser fan unit shows that a stick had fallen into the fan, blocking the blades and preventing the fan from starting. The brand of the Unit is Heil with a GE motor. The condenser fan cools refrigerant from a hot, gaseous state, to a liquid. Other compressor units such as those used. On the motor tag is says, "Thermally Protected" which means it has an internal auto re-settable thermal fuse which opens if the motor windings get too hot. Fan belts are components that wear down over time. I think it is a 13k but unit. The radiator and condenser are BRAND NEW. Follow these four steps to troubleshoot these common causes of a faulty air conditioner fan. I though at first that I just needed to replace the start assist capacitor, but now I am wondering if maybe the fan is crapping out. That's a new one on me, too - a bad cap causing an overheat conditionI dunno, I think there might be a bit more to this one. Its hot. The fan motor and capacitor have been replaced. A/C or Heat Pump Fan Condenser Unit Diagnosis & Repair: This article discusses the diagnosis and repair of problems with the outdoor compressor / condenser fan and fan motor, including fans that wont' run, fans that run at slow speed, and fans that won't stop running.

Clean the dirty condenser coils. The capacitator losing its charge. Fan is still intact. Freedom Air and Heat, Inc. Most air handlers and furnaces have a small flashing light on them. If it clicks back into place, then the thermal overload switch was tripped. A malfunctioning thermostat. Complete the wiring, taking care the connection is correct. Not enough space clearance. I ohmed the 3 motor windings and they add up correctly. If either of these conditions exists, then the fan motor is bad. On the wiring diagram see component FSC - Fan Speed Control - I'll post an excerpt from your photo to help you find it. 12 - Sub Zero Refrigerator Condenser Fan Motor. Replaced capacitor because it was cheap and could get next day. I don't mind paying for both the capacitor and the fan motor, but of course do not want to spend more than necessary. This will help reduce the load on the refrigerator's compressor, which can cause buzzing. This is speculative. The AC is OFF. Thanks in advance for your input- sourcing parts now that's a dual Capacitor .. two sections .. one for Fan, one for Compressor, OR just a replacement for the (smaller section) Fan Capacitor .. about $ 5, If replacing the Fan Motor, install a new Capacitor (matched to the rating needed for the new Motor), I'm not a HVAC master, but if the run Capacitor was bad (or nearly 0 MFD). Many contactor contacts get dirty after a few years of use. A capacitor may be used to start the fan and keep it runningas in a start/run capacitor. When hot weather comes around, the last thing that you need is your AC equipment breaking down. If its tripped, flip the breaker to off then back to on. If the issue persists, contact a professional. Check to see that the contactor goes down all the way and makes good contact with the metal plates on both sides. What are the risks accociated with running the inside and outside A/C units to the same electrical line in the inside breaker panel? You may detect this by noticing that you can wobble the fan motor shaft (when power is OFF) or you may notice that you can pull the shaft in and out of the motor (loose end-play).

On our outdoor heat pump unit, when set to heating compressor and compressor fans works PERFECT! If you don't have a meter they aren't all that expensive. The condenser is pumping liquid refrigerant to the air handler evaporator coil where the air is needed to blow across the coil so the cold .
