PDo let me know what your service repair technician says. ugh, I mean I did those 2 tasks separately hehe. Watch out: the wiring instructions and diagram for your specific air conditioner or heat pump compressor/condenser unit are model dependent. 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. 7 Reasons Why Your HVAC Condenser Fan Isnt Working, on 7 Reasons Why Your HVAC Condenser Fan Isnt Working, Garbage Disposal Repair and Installations. Is there fluid leaking out of the capacitor? 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. Check for loose wires or loose components on the fan unit control circuit board. 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?). (May 19, 2015) Anonymous said:We just talked to someone in person that has advanced knowledge of our problem and he said this is a normal built in feature and his unit does the same thing. I can hear the coil from the tinny fan control circuit board turning the fan off and then back on during this problem. It may be the AC condensers compressor or fan. It had gotten down to 62 degrees. At worst, it could cause irreversible damage to the compressor. If the fan spins on the motor shaft and the motor shaft won't turn the motor may be seized and need replacement.

Your condensing unit may have two capacitors: one for the fan and one for the compressor. When the compressor cycles on, it also feeds a line to the condenser fan relay, running the fan. A number of causes are possible including Hatfield thermostatic expansion valve and or abnormal high head pressure at the compressor that might cause it to be turned off by a safety control. Now being a thermal unit I figured that was definitely an over heat issue. When the fan motor overheats, the thermal overload switch will trip. I check the uF on the cap with my meter first thing. Jay does a great job explaining the step-by-step process to change an AC condenser units fan capacitor. One of the most common reasons fans stop spinning is because of a dead capacitor. Fan is brand new. Thought that AC wasn't cooling 100%, and low and behold went outside and condenser fan was not turning and fan was hot as well as entire unit. 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. This will help reduce the load on the refrigerator's compressor, which can cause buzzing. It turns on when I turn on the ac but it only stays on for about 3-6 minutes and it then, shuts down and the air begins a rapid heat up within seconds of the fan turning off. Is the fan blade assembly secured to the fan motor shaft? A simple problem like this can also burn out a fan motor. This process converts hot refrigerant . Problems With Power An air conditioner (AC) can start and stop after a few seconds because of short cycling. Sorry Jedson but I don't understand the question. Still same issue. Now the compressor comes on (freon line gets cold) however; the condenser fan is not running but humming. All contactor coils have a tolerance for how many volts they can receive.

If the compressor/condenser unit is wired with 240V (or "220 volts") as most are, an overcurrent at compressor start-up may be tripping just one leg of a two-pole breaker or one of a pair of fuses, leaving the other circuit "live". Typically, there's an on-off . But it seems to me that that condition should not be for long. The parts are priced at $245 to $330, while labor could be $55 to $200, depending on your make and model. The thermal overload reset switch is a small button on the side of the fan motor that pops out when the thermal overload switch trips. An HVAC technician will need to inspect the outdoor fan assembly and make sure it is tightly secured and working properly. Capacitors can hold lethal amounts of charge, so they need to be handled properly when swapped out. The heavy fan motor is mounted on the panel, so have a helper hold it while you install the blanket. 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 am thinking of asking for a second opinion just to be sure before I sink money into a new coil. If the condenser fan doesn't when the compressor is on, then is due to one of the following reasons: Condenser fan capacitor is bad. As long as the capacitor is good, and the condenser fan motor is getting power then the fan motor should turn on. When the capacitor fails, the condenser fan will no longer rotate. Inside the house is warm and could have been blowing warm air. Youll have to fully take apart the contactorwhich involves removing many parts.

The fan turns off outside and doesn't come back on until I switch the ac off and wait at least an hour or so n but it is still blowing air in the apartment. In looking at the posts it seems like folks are being pointed in direction of capacitor or fan motor. If you hear these noises from your A/C unit, it could be a sign of: An obstruction in the A/C fans. Still same, fan on condenser stops after a few. Capacitor is brand new. 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. 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. I don't mind paying for both the capacitor and the fan motor, but of course do not want to spend more than necessary.
