Problem I turned on my air conditioner this spring. I turned the switch to cool on and the air conditioner fan not going. I took cover off and got new capacitator didn't work. I took fan motor into electric shop and checked out fine. When I turn switch on the contact switch engages and there is a humming noise. But the fan does not work. the compressor doesn't start up. The model is at least 10 years old. How do we tell what the SER rating is?

The fan or blower motor is not turning when I switch air conditioner on.


The model number as listed on the receipt is CKQ24. The Blower moter in the air-handler is not running. When the fan-only switch is turned on, the blower motor will attempt to spin by pulsing for about 2 seconds. It will repeat the pulsing cycle in about 2 second intervals. There is no smell of burning. When the unit is set to AC and auto, the evaparator coils do chill. The blower motor is a variable speed motor with an external ECM. How do I test the ECM and/or motor? What should I look for in

Personally I would get an exact replacement capacitor same voltage rating and microfarud rating. The capacitor will read something like 370v 5uf. I would be surprised if that's not the whole problem. If not it needs an exact evaporative fan replaceme ... Goodman CKL24AR24 Air Conditioner

Hi I have a CLT30-1A external air conditioner unit. Problem: both the fan and compressor do not turn. A low frequency hum sounds when power is applied. Trouble shooting steps I've tried; 1. contact switch works and supplies 220 VAC across contact to motors 2. removed each motor from the circuit at a time but neither motors function. I speculate the capacitor is not functioning and does not "start" either motors. What do you think?

Hi,If your contactor is engaged, as it sounds like it is and you have 220 volts going out of it. Then the capacitor would be the device to look at next. An ohm meter test on both sides of capacitor should show its condition. I ... Goodman Air Conditioners

Blower fan in the inside unit tries to turn on but wont. It can be turned manually and air conditioner comes on and runs fine. The " squirrel " cage spins completely freely and is not sticky or jammed. Is the motor bad or is it a run capacitor. Model number of inside unit is a49-15

The motor or blower wheel om my Goodman model GMP 100-4 unit whistles and sticks. How can I fix this? Can the motor or blower wheel be lubricated? Does the motor need to be replaced. If I manualy spin the blower wheel and get it turming some what and then start the unit by pressing the safty switch located behind the lower front panel the blower will start, the wheel fan will turn. If I turn the unit off and try to turn it on again before the wheel stops turning the blower will work. But, if

I have a Dometic 579 Series Brisk Air AC. The model Number is 57915.531. When I turn the fan on, nothing happens. If I reach up and turn the wheel blower the fan will start up and everything works. I replaced the fan motor and put on a new capacitor part # 3100248.412 was supplied. The fan still will not start on it's own. I still need to turn the wheel blower to get it started. Help!

I have a goodman Air conditioning unit CKL49-1. The fan motor connects to the top lid. Recently the metal cracked and broke and the fan fell down inside. I purchassed a new lid mounted the fan back on to the lid. It doesnt seem that any major damage was caused. I put everything back together the way it was. When I turn it on it will only go on for a sec then a switch inside turns it off. When i looked at the electrical on the ac i noticed when i turn it on a little spark on a switch and the swit

Sounds like it is overloading and tripping the circuit breaker (that thing that pops up). More than likely when the fan fell down it stopped the blade from turning which caused the motor to overheat, melting the windings insulation which caused them ... Goodman CKL49AR49 Air Conditioner

Air conditioner runs for a few hours and it works - it cools the house. Then it stops cooling - the fan still runs but it doesn't blow out cool air any more. It seems like it's overheating or something. It will blow out cool air if it has not been turned on in a while but once it's on too long it stops. I was told it could be the fan motor and the a/c guy changed the fan motor today but that didn't fix the problem. Now he says it might be the compressor or that I need a new system. I'm jus

I have a Carrier 5 ton Air Conditioner -five years old. I turn on the thermostat and the blower comes on in the house then the compressor engages, but the fan does start.

Is the fan on the outside unit supposed to turn when the heat is on or only for the air conditioner? Our unit is omitting a strange odor and the fan will not move even if we switch the unit to air conditioner.

The outside fan is used when ever the compresser needs to be cooled. So depending upon the outside temp as well as the temp of the refrigeration, it may not come on. When you say "our unit is ommiting a strange odor" are you refering to the outside c ... Ruud UAKA042 Air Conditioner

Blower motor stopped, there is a medium-loud ''electric buzz'' sound every minute or so as if trying to start the blower motor. Could be relay switch. Last week, I extracted the entire motor and fan assembly (the one in the bottom of the furnace that drives the air through the house duct system). The motor was pretty filthy, so I took the entire thing apart an blew out all the dust, cleaned up the motor, Zoom oiled the bearing assemblies at each end, put it all back together. Started up and ran
