If it is an air conditioner check for an air conditioner breaker trip. Am I barking up the wrong tree and should I be looking elsewhere? The fan capacitor may also be labeled. Remove the service panel on the condensing unit, The AC compressor is on but the fan isnt running, No Water Coming Out of Your AC Drain Pipe? Over an extended period, that will cause the fan to stop working. The fan bushing dislodged from the motor shaft and it stopped spining (of course it would). Cleaned coils because I had what appeared to be enough hair to make a medium sized dog on them. My heat pump has a similar issue only in reverse. A blower fan may run for a brief while after the compressor motor has stopped but if the outdoor fan never stops check for a problem with the control board wiring or circuit. Figured I'd revamp all the cheap parts. Read on to find the best solution based on the cause of the problem. A capacitor may be used to start the fan and keep it runningas in a start/run capacitor. The dark blue fan shown at right in the sketch is the indoor air handler or blower compartment or cooling coil fan found inside the building. Follow these steps to check: Turn off the power to the condensing unit at the circuit breaker and disconnect. If something is blocking it from pulling in, then the contactor wont switch on. The condenser fan should always be running if the compressor is on. On 2020-06-17 - by (mod) - Humming fan motor. Check for loose wires or loose components on the fan unit control circuit board.

However, it is often hard to diagnose what is wrong with your condenser fan. 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 -. And the AC compressor stops prematurely. The problem still came back in the mid day heat. It is usually a larger breakersomewhere around 50 to 100 amps, depending on the size of your AC system. The outside unit doesn't turn-off when the thermostat turns-off the inside unit. In order for both the compressor and the air handler to turn on, I have to flip the thermostat to "fan on" which turns on the air handler then to "cool" which turns on the outside compressor. Proper and regular lubrication of the fan motor is necessary for the motor to run smoothly. One of the most common reasons fans stop spinning is because of a dead capacitor. Cocoa/Merritt Island/Rockledge 321-631-6886 Remove the access panel to the blower compartment. A faulty cooling fan relay can also negatively affect air conditioning (A/C) performance.The reason being, on most vehicles, is that the cooling fan doubles as a condenser fan.When the A/C is turned on, the fan moves air across the A/C condenser, thereby removing heat from the refrigerant, which changes from a vapor to a liquid state as it gives off heat it . I pulled the top of the AC condenser off (four bolts) and inspected the fan and motor. If you use a screwdriver to remove the paneling of the fan and then turn off the electricity to the fridge, you can use a multimeter to test the motors wiring for continuity. We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. If the fan itself is balanced and undamaged and secured to the shaft and the fan motor buzzes or hums the motor may be damaged, overheated, have an internal bearing failure, or the motor may be hard starting.

Im at a loss. yes, I am not familiar with the proper terms. Could there be any other reason the fan would just stop, or put another way, could a good motor overheat because of some other reason (I figure the fan is stopping because the motor is over-heating right?). Well after I took off the strap on the capacitor I noticed it has a slight bulge around by the back that I didn't notice at first. 2. Any suggestions? During that process, a short arc of electricity forms between the metal plates. Plug electronics into a power strip and turn it off when not in use. 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. What would be the risk in not connecting the red wire to anything and just connecting the brown, black and yellow wires? with power removed, try turning the Motor shaft by hand..using your fingers Can you give it a twist, and it will continue for a few turns ?
