The fan would run for a while then stop. That aids the defrost process and helps melt the frost on the unit faster. This is speculative. Maintaining the condenser fan motor can help to prolong the life of the AC compressor. When the compressor cycles on, it also feeds a line to the condenser fan relay, running the fan. The next possible problem that can occur with the condenser fan motor not turning is a bad run capacitor. Heat Pump AC Condenser Fan Motor Not Turning - Both heat pumps and air conditioners use the process of refrigeration to provide heating and cooling. The problem still came back in the mid day heat. Heat Pump Condenser Fan Motor Not Running. Any idea what this could be? But it is indeed also normal for the fan on-off cycle to sometimes be different from the compressor motor on-off cycle. What Your HVAC Technician Will Do Conduct a Visual Inspection. If the fan motor does not turn on while you hold the switch, the motor is probably bad. I notice the red on the unit is coming off of a small circuit board that says low. Finally, there are times when the condenser fan motor will fail making a repair necessary. A/C or Heat Pump Fan Condenser Unit Fan diagnostic questions & answers - FAQs: Questions & answers help diagnose problems with the air conditioner or heat pump condenser unit fan: fans that won't start running, won't stop running, hum, click, buzz, or run intermittently utlimately lead to loss of heating or cooling. If it does, your job isn’t complete yet. You begin checking everything, including the breakers — eventually, the units themselves. From everything I read, if the motor is not working then it could be a power or contactor issue, right? Again, I advise you to call a professional to take care of this problem as we are dealing with high voltage and capacitors. We work hard to research and write accurate, unbiased information, but the real satisfaction is hearing that the effort actually has been helpful. Bob,Thank you for the helpful diagnostic question about your Pioneer brand Mini Split AC unit. The brand of the Unit is Heil with a GE motor. If the run capacitor is defective, the fan motor might be noisy, overheat, or not run at all. Try the search box just below, or if you prefer, post a question or comment in the Comments box below and we will respond promptly. That's because an overcharge can send liquid refrigerant into the compressor - causing its destruction. Step 2: Remove the service panel on the A/C unit. These cookies will be stored in your browser only with your consent. The first thing you need to know about the system is the type of motor you have installed in the condenser. Furthermore, instructions will be provided below on how to proceed if you find this problem. The first thing you need to know... PSC Motor Solutions - Problem One. It is best to replace any capacitor with an exact replacement. Check the float switch. Your might ask for an explanation and let me know what you're told. Scenario B: You cannot hear the a/c compressor running and the fan motor is not turning. What would be the risk in not connecting the red wire to anything and just connecting the brown, black and yellow wires? I am not convinced the fan was fixed either the first or second visit. You will find further instructions on how to wire a run capacitor to a motor here. I'm not sure how refrigerant leak would make the fan run intermittently. - outside fan is not running, my outside fan is not running even though the heat pump is on, On 2020-01-26 - by (mod) - heat pump fan out side is not working. The four screws of the fan motor to support frame were still tight, as were the four bigger screws attaching the framing to chassis (minus spacers). How Do I fix it? The should be no plug on the downside of the motor. I get calls all the time about heat pumps and the condenser fan motor not turning when in heating mode.

If you continuously reset without fixing the problem, then you could cause further problems. A bent condenser fan causes stress on the blower fan motor shaft and can destroy the motor. See if you can find the wiring diagram for your condenser unit - often on a sticker in the unit, or always in the IO manual for the unit. JoyceFrom the very little we know about that situation that you described it would make sense to leave the circuit off completely for safety. Moral of the story: do it yourself and use the right capacitor. You can do this at the transformer, checking for a fuse in the low-voltage circuit. For mounting purposes. Finally a senior tech came out and recognized that the fan required a different capacitor than what was initially changed in. A dual capacitor powers both the compressor (HERM terminal) and the fan motor (FAN terminal). If you have this type of motor, the first thing I would do after killing the power is to go and get a long and thin screwdriver. Other compressor units such as those used.
