Nothing. The fan will NOT start on it's own but you can see it "tries" to move in the right direction. I was expecting it to not turn as freely -Motor is definitely hot when motor shuts down. Clogged air filter. Condenser fan motor runs backwards. Take a look at the circuit breaker associated with . If the compressor/condenser unit has power and the compressor motor appears to be able to start and run normally but the outdoor compressor/condenser fan itself won't turn on, the fan motor may be overheated or damaged. Is there fluid leaking out of the capacitor? Also, noticed the old fan wire actually has a quick connect coupler for all four wires to connect into a circuit board. The heavy fan motor is mounted on the panel, so have a helper hold it while you install the blanket. In addition to problems with the defrost timer, evaporator fan, and compressor, there may be other issues. The inside unit uses . Be sure that nothing is rubbing or hitting. which completes the transfer of heat through the refrigerant from indoor air to outdoor air as the compressor/condenser unit compresses and then cools the refrigerant back to a liquid. If the refrigerator runs constantly there might be something caught in the condenser fan motor blade, or the condenser fan motor might be defective. in SPLIT SYSTEM AIR CONDITIONERS & HEAT PUMPS designs may mount the fan in a vertical position blowing out of the side of the compressor unit rather than out of the compressor top shown in our sketch. Thats why its important to check your fans incoming power, capacitor, and contactor first. I then went online and bought a new fan for $22.00 and installed it. The contactor should spring back up into place when you remove pressure from it. Over time, the contactor switch gets worn, and will stop providing voltage to the condenser fan. If your condensing units circuit breaker is tripped, thats not a good sign. On 2020-06-17 - by (mod) - Humming fan motor. Fan control circuit board is brand new.

Cocoa, FL 32922 a really weak cap might start the motor and overheat it , but a bad cap will never be able to give the motor direction (the cap makes a phase shift in the delta type windings this gives the motor direction ), again i go back to the way the motor stops and a clue to the motors health , and it's not good. The next task is figuring out why the thermal overload tripped in the first place. Also. The compressor is depending on the fan to move air across the condensing coil to convert high pressure, high temperature gas back to a liquid refrigerant. Finally a senior tech came out and recognized that the fan required a different capacitor than what was initially changed in. Fan spun fine for a few minutes, the crapped out. Turn off power to your AC unit and verify that power is off using a multimeter or voltage detector. Broken Motor. A malfunctioning thermostat.

Now if the condenser fan runs in "heat" you may have a problem with the fan relay or the main controller. It had gotten down to 62 degrees. The air conditioner or heat pump condensing coil (shown at left) receives high pressure refrigerant gas from the compressor and cools this refrigerant gas back to a liquid state. Typically refrigerant leaves the compressor and enters the outdoor condensing coil at about 100 psi and about 95 degF. Step 4. Could this just be the run capacitor? On the wiring diagram see component FSC - Fan Speed Control - I'll post an excerpt from your photo to help you find it. The fan motor is located behind the fan itself.
