Many contactor contacts get dirty after a few years of use. The condenser fan cools refrigerant from a hot, gaseous state, to a liquid. 3. This can leave the fan motor running. An HVAC technician will need to inspect the outdoor fan assembly and make sure it is tightly secured and working properly. Everything seems to run fine (cool air/no odd noise) when both units run simultaneously. 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. And the AC compressor stops prematurely. The motor was hotter than you know where! If the condenser coils are too dirty, the air conditioner's cooling power is limited so the system has to keep running in attempts to cool each room. Or more likely the fan motor? (May 20, 2015) Aubrey said:Correct. Gently slide the stick between the vents and give the fan blade a slight push. Background, been working fine for years. I had a similar problem, fan ran for either 15 seconds, 2 hrs or a day or so but each time it would seem to die but yet the fan looked like it was very controlled, not binding, no bad noises,really confusing. I notice the red on the unit is coming off of a small circuit board that says low. Its hot. Anything else make it shut down like that? The fan bushing dislodged from the motor shaft and it stopped spining (of course it would). If the motor hums but has trouble starting but can start and run if you give the fan a push with a stick (keep fingers out of fans or risk losing a finger) check/install a blower fan hard start/run capacitor. ", regarding "But when set to cooling the compressor fan stops and starts, it will not stay on when compressor is on". Dodge Master. Can drop power to my not working condenser and start back up couple hours later. Be sure that nothing is rubbing or hitting. Turn the air conditioner completely off, and call in a professional right away to diagnose the cause and prevent further damage to the system. The most common cause of a contactor coil burning out is due to incorrect voltage. Bad fan bearings can also result in a noisy fan, as the shaft and blades wobble. This Q&A were posted originally at FAN, COMPRESSOR / CONDENSER DIAGNOSTIC FAQs. Thermostat Issues. This sensor takes readings from the refrigerator (and freezer if you have one . Figured I'd revamp all the cheap parts. The condenser fan motor is located underneath the refrigerator near the back. Is there fluid leaking out of the capacitor? I think I'll try checking the ohm load on the motor. Read further to diagnose the issue. I replaced the motor and the capacitor and neither fixed the problem. 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. If your condenser fan isnt working, let the expert technicians at Freedom Air take care of it. Turn off the breaker or thermostat . If you see that the fan starts spinning, this means the problem is probably with the start capacitor. I check the uF on the cap with my meter first thing. Fan Selection: Depending on vehicle design, the fans may operate singly or in . Shut off your AC and check the fan capacitor, contactor, and motor if the condenser fan isn't running when the compressor is on. Guest horn4life The condenser fan motor draws air over the condenser coils to cool them. This is usually the case for air conditioners with rotary dial thermostats. Fan Only Switch.

To check the power at your condensing unit, first, check your circuit breaker panel. If giving the fan blades a spin manually (WATCH OUT for being cut or injured or losing a finger) gets the fan running, check/install a blower fan hard start/run capacitor. 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 ? 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. 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. When your system's air filter is full of . 2. But it is indeed also normal for the fan on-off cycle to sometimes be different from the compressor motor on-off cycle. I installed it following the install instructions to the letter. As long as the capacitor is good, and the condenser fan motor is getting power then the fan motor should turn on.

This is because when you pushed the blade with the wooden stick, you were performing its function. Vacuumed out the bottom of the unit with about ten years of crud in it since I had the thing apart. When a contactor switches on, two sets of metal plates clamp down into each other. Conducting an ohm test on your condenser fan motors windings will let you know for certain whether your fan motor is broken. the motor may spin by hand no problem ,even if the motor is bad, your replacement motor most likely will be a universal motor that will use it's own cap , that will be a 5 mfd to a 7.5 mfd . Remove the access panel to the blower compartment. Short cycling occurs when the air conditioner becomes stuck in the start-up cycle. AC ran fin all Summer of 2018. Check for a refrigerant leak. The AC ran for about 1.5 hours and then shut down the fan due to overheating. Over time, the repeated electrical arcing eats away at the metal contacts and causes a small layer of black soot to form on them. 7. So is there an easy way to test to see if the fan motor needs replacement? Humming fan motor usually means either a bad starting cap or a seized motor. Changed compressor starter capacitor but not the dual run capacitor.
