The controls on a unit like that cannot be set to extremes on one side. If you set the freezer to the wrong setting or the refrigerator to high then the balance is bad. The other thing is that the coils inside the unit might have ice on them and the ice is not defrosting. That means that no air is flowing through them.
You will need to remove the cover around the condenser fan motor then remove the screws holding it down to the base. Remove the wiring from the junction box and away you go. Do not run the unit without a working condenser fan motor, you run the chance of causing yourself many other problems. With a new fan motor the unit should run fine unless there is waxing in the cap tube from overheating.
An abrupt cycle of power can cause a motor to run backwards. If you turn the power off again and wait 10 seconds or so (enough for blade to stop spinning) it should run the right way. Put the capacitor back the other way and try again.
Yes, if you changed the three post capacitor that runs the fan and compressor, and the fan is still getting hot and shutting down until it cools off, you may have bushings out of the motor or an internal short. Sounds like you have a job ahead of you of changing your condenser motor. If you do this yourself just contact me I will step you through it . Mark
I had a unit do the same thing to me, everytime I would leave, it would stop working again. I had a bad fan motor that would spin fine and work for a little while, but would shut down. It was the motor windings that would overheat and shut off, as soon as they cooled, it would start back up. One way to check is to feel the top of the unit where the base of the fan mounts and see how hot it is, best to check while it's not working how it should, but try not to run it very long or you could damage the compressor. Hope this helps!
You have a direct short in the A/C unit probably at the compressor or your condenser fan motor. You can disconnect one component at a time to identify where it is shorting. turn power off unwire condenser fan motor secure wires so they dont touch anything plug unit in if it still pops breaker your compressor is probably bad.
Hi, the tech should have been able to figure the stat out with out a manual to see why the condenser is shutting off at 1:00 P.M. This is unusual for this to happen, unless it was winter and this is a heat-pump going into defrost, but just the fan would shut down. Does this unit have a box on it that was installed by your electric company that shuts the unit off during high peak conditions in the summer? This would cause it to shut down at the same time everyday. If not, it would have to be something in the thermostat that is set for it to shut off at that time. It still does not make since, as it would shut both the indoor and outdoor unit off, not just the condenser. Are you saying that just the condenser fan motor is shutting off, but the compressor continues to run until it shuts off on high head pressure when the fan stops, or does the complete outdoor unit shut down fan, compressor and all at that time??. It sounds to me like this outdoor unit has a time delay relay that has a fault in it may be shutting it off at this time daily? Please let me know if its just the condenser fan motor that shuts off, or if the complete unit is shutting off all together, this will help . Sincerely, Shastalaker7 A/C, Heating,
Hi, To give you an answer, no it doesn't take anything special to repair the condenser fan motor. This key stock you bought will work just fine as long as you can use it ok. Those outside studs tend to rust as they are in the weather year around, so I would cover it unless it is a heat-pump which runs year around. If not, you can cover it to keep the leaves and debris out of it. Just about any grade of threaded rod will be fine. Sincerely, Shastalaker7
Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.
version of adaptive defrost : Press
refrigerator light switch five times in six seconds to initiate defrost cycle.
Pressing five more times within six seconds will cancel defrost and go straight
into the run mode. Similar operation on both bottom mount and SxS refrigerators.
After the defrost terminator/thermostat opens, six minutes of dwell time occurs
before the compressor and condenser fan motor will operate. After defrost
terminator/thermostat open, 10 minutes of dwell time occurs before the
evaporator fan motor will operate.
