Question about Heating & Cooling

1 Answer

I have a 24000btu ramsond split system. running for a yr, had to change out fan condensor and capacitor. now the problem started when we noticed the outdoor unit was shaking like a washing machine. then it dosent blow cold anymore. i checked the capacitor for compressor, which showed no ohms. i swapped that out and it says that it has 3.8 ohms, but when i put the meter on the ohms symbol )))), it makes that constant ring, which my father in law say is straight shot to ground. so now i dont know what else to do? is the compressor bad? any input would be greatly appreciated!!

Hi, you can get a proper reading with a ohm meter when checking a run cap. All it will tell you is that the capacitor is not open internally inside if you have the ohm setting that sounds off. Its not ground or shorted to ground, but look on your meter to see if you have the symbol for capacitance, like uf's. It will look like this -). On this compressor the capacitor will be stamped with a number like 35, 40, 45, x 370 volts, or 440 volts uf. This is the microfarads. If the capacitor is not leaking oil, or is not swollen or deformed in any way, its probably good. You can have it checked at any a/c shop for nothing to see if its putting out the right amount of microfareds, the 35, or what the compressor calls for. If its good, your compressor from what you said was like a washing machine has probably locked its rotor up, and will need to be replaced. Its really to bad that you spent the $$$$ to replace the condenser fan motor and run cap, but this happens. Depending on the age of this unit, it may be cheaper or you may be better off installing a new 2 ton unit. 24,000 is 2 tons of cooling, as 12,000 btu's equal 1 ton of cooling. A 21/2 ton would be a 030 in the model number. Yours will have a 024. You can pull out the new motor and save or sell it. This would be your call. I can tell you how to check to see if the compressor is shorted to ground. Remove and mark the wiring at the compressor terminals. Set your meter to where it will beep. Now, touch each terminal with the red lead and the other to a clean piece of copper tubing on the unit. Do each one. If any one of them beep, that winding is shorted to ground and the compressor is dead. If not, and the run cap is good, the compressor is locked up internally. I see this everyday. I wish you the best of luck, and I know its frustrating as hell, but it happens. Please don't forget to rate me on this as I know you will be kind. I have all of your information I keep on file, and will be checking in to see how it is going for you. The compressor was trying to start when you saw it acting like a washer, but has locked up and either shorted to ground. Please keep me posted also.

Crosley CAE12ESR air conditioner turn on but not blowing air. Only making buzzing sound. Cool and fan not working.

You can try this. Remove the cover, spin the fan by hand and see if the motor runs well after this, if so, the capacitor or motor condensor is bad or has defective wiring. Replacing it should take care of the problem. Some capacitors are split capacitors, have two values and serve both a fan motor and the compressor. In this case, the unit can be rewired for individual capacitors or the split one replaced.

Fan not turning on ramsond split unit

If it is the outdoor unit it usually is the capacitor. This has always been the problem with mine however I never changed it myself. (Looks easy to change though.) Usually this visit turns into a basic check up for the system. Since the repair is by the hour get the most out of the time.

Condenssor fan moter not working

The condensor fan is usually a capacitor start capacitor run motor.To test i switch the unit on as normal then carefully flick the fan around in the direction of rotation (you may have to take the grill off) to do this,do not use your hand! If the motor starts to run it will be a faulty capacitor, do not leave it running for long as it will not run at full speed and will trip on thermal O/L or burn out.This is a common fault on AC split phase motors that use a capacitor for either starting or start and run.

The condensor is not cooling fast enough. Try cleaning the condensor coil. Also check that the fan goes on. At night the outside temperature is cooler and does not need much work to cool down the condensor.

Fedders 208/230 split system w/ dual cap , compresser runs but fan wont unless you give it a push , compresser won't restart if relay is hot

All kinds of stutt happens when you dont have a condensor fan motor. You need to change the run cap on the motor.

Hi there i have a delonghi one split system air con. unit cools good for a minute or so then starts to struggle blowing warmer air. i have noticed the condensor fan on the unit out side does not turn on....

Either the fan motor outside is bad or the run capacitor for it is bad. One quick way to tell, you just have to be really careful, when the compressor turns on get a long screwdriver and spin start the fan. If it starts turning then simply replace the start capacitor, which more than likely will look bloated. If it doesn't start then you need to replace the motor.
