Having problems with your Air Conditioners ?

My Ruud heat pump fan stops after running a minute. It is 10 degrees out now and defrost mode seems to work fine. It makes a humming sound when the fan gets stuck. Sometimes if I take a ruler to it, it will unstick and starts spinning but not other times. cover over the fan motor feels very warm, almost hot to the hand. I've shut it off totally for now.

The outside unit is no0t able to start the fan spinning on its own. I have been able to manually engage the outside fan by turning the unit off, turning it on, and then manually spinning the fan when it starts up. The unit will then engage the fan and runs fine until the next cycle when it cannot start the fan on its own again. Can you tell me what part needs to be replaced and about how much it will cost?

Hi!!\015\012\015\012The part you need is called STARTING CAPACITOR and it is located in the same compartment where the electrical connectors are in the outside unit. MAKE SURE THE POWER BREAKER IS OFF before opening the compartment. and befor ... Air Conditioners

When calling for cold air, the fan in the cooling unit hums, but does not spin. With a nudge, the fan does spin. Looks to be smooth and normal speed. However ambient outside air 80 degrees. the air through the register is 72 degrees. Is there a switch that will not allow the fan to start on its own if the coolant is too low? Do I have two problems, fan starting AND insufficient cooling? Unit worked well the last two days.

Our evaporative cooler fan does not start when we turn on our unit - it will run if I get up on the roof and start the fan blades spinning... We could smell a burnt motor smell when the problem started. Is it just a fuse? or is it a new fan motor? We just spent $600 to replace the circuit board and the solenoid - hoping to avoid another big bill...

Hi,It is just the circuit problem.Not fuse not motor.From the circuit board to the fan there is no start flow of current passing on to spin or to make it start.Check the flow of volts out of the board.Please do rate the solut ... Air Conditioners

The fan on the condensing unit isnt working it works for awhile and then shuts off,then the compressor starts to work by itself really hard and the whole condenser heats up really fast so I turn off the breaker and start it again but the fan makes and electric humm and I have to push start the blades to get it to spin and then it will work for awhile and then the fan will stop again after about an hour and then same thing happens

Does the fan turn freely or is it hard to turn by hand? If it is hard to turn the fan motor may need to be replaced. If it isn't hard to turn then check the fan capacitor. You can test it with a multimeter or take it to a heating and air supply and g ... Goodman CLT36AER36 Air Conditioner

My fan will not start, if I take a stick and spin it it starts. I have replaced the fan motor, capacitor and start relay. Even bypassed the start relay, all have same problem. I had 2 cousins that have been in the HVAC field for 20 plus years each and they dont know the problem.

Supply the fanmoter from a completely seperate source of power and confirm that it is working. If it works, look at your supply board and contactor relay if there is one. ... Air Conditioners

The compressor fan wouldn,t run even if I spun it! I replaced the run capacitor 15uF 370 volts(but is getting power) and now it runs if I spin the blades but will not start on it's own! Motor has been cleaned and lubed! It is smooth and no resistance. The large capasitor(compressor/(fan start??)) is bad also?? I have replaced all of the contactors and cleaned the coils, Etc..

Hi,\015\012It sounds like the motor is weak and that it still doesn't have enough torque to get it started.\015\012You can try a bigger Cap. as bigger will not hurt anything. Would go over 30uF though.\015\012If it was me, I would j ... Air Conditioners


Be careful.....! If it starts when you push it you can hurt yourself seriously from the spinning blade. Sounds like your motor has a bad capaictor. Turn off the power (circiut breaker). Remove the old capaictor. Find the ... Goodman CLJ30AR32 Air Conditioner

I have RUUD and just replaced the condensor fan motor with a 5 wire Protech....the old fan was wired with black connected to contactor, orange to one side of cap and brown to the other side of the cap.....The new motor is a five wire...I have black connected to the connector, orange to one side of cap and purple(to change direction of fan) instead of brown...now i have a yellow and brown wire left over....Now when I start the unit the fan will not spin unless i turn the fan blade manually....am

I installed my attic fan about 10 years ago. Now, it will not start without me giving the blades a push. It hadn't been lubricated since installation. So I applied some 3-in-one oil. Still wouldn't start on it's own. Then I tried some WD-40 and it would start better. But then, not running overnight, again it wouldn't start without giving the blades a spin. Any suggestions?

I have a 2002 year model trailer, it has a Duo Therm Quick Cool High Efficiency by Dometic. Because the fan motor would not start by itself, it popped the breaker after a couple minutes the first time I turned it on this year. I took the top off the unit and give the fan a little spin and it would then run. Once again after a few minutes the breaker popped. I changed the capacitor for the fan but it does the same thing. Could it be the armature in the motor causing the problem? Any sug

Nordyne AC Hello, Our Nordyne DT5QD-042K quit cooling the air. It sounded like the compressor was starting and heat was building up however the fan on top was not turning. It did spin freely and showed no sign of bogging down. Power was present at both leads from the capacitor. Ohmed lead to lead and had resistance, nothing going to grnd from either lead. Last September I had to install a booster capacitor and all worked OK (the fan was operating at that time). I am suspecting the fan mot

Condensor fan wont start on its own. have to give it a spin to get it going. is it the fan motor or whatever controls the fan ie...switch, sensor, circuit card ,thermostat?

Most Likely your Condensor Fan Motor is bad. Pull the motor and hook it to 110 to eliminate any other possible causes. I am sure that is where you will find your problem. ... Air Conditioners

The compressor works. The fan seems stuck. If I take the covers off and spin the fan, it works. If I put the setting on auto the fan won't start up. Any suggestions?

Sounds like the capacitor for your fan is shot. This is a very inexpensive part and will cause the fan to act just as you describe. You can check it with a multimeter that has the capacitor check function. Take the old one with you to get the new one ... Coleman Mach 15 Air Conditioner

Amana heat pump emergency heat comes on but blower will not start. The call for heat comes in and the heating element(s) glow red for a few seconds and then there is a "click" and the heating strips de-energize. The blower fan motor doesn't come on, however the squirrel cage fan spins freely. The heat pump stopped working several years ago, but I just used the emergency heat option for heating solution. The squirrel cage fan motor was replaced about 3-4 years ago.

Had "So Called" RV repairman work on Coleman 13.5 Roof AC! He said he fxed it first by lubrication then he replaced the "Hardsart" and told me if the fand stopped again to spin it to get it started and said I should just replace the AC. Another Mechanic PooPooed that Idea and ended up removing the "Hardstart" and wiring direct from the Diod! The sytem worked perfectly for a couple of days then the fan shut down again! Leter on I tried it again and after a "Clank" she started again and we turned

If the fan is not turning, but just humming, you need to replace the capacitor. If you were to spin the fan by hand (carefully) when it's doing this, it will speed up and run, until next time. The "hardstart" they refer to is for the compressor and i ... Coleman Mach III Air Conditioner

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.

My Goodman GMP100-4 blower fan runs slower than the second unit. The blower did not start when I turned the A/C or furnace on. However, if gave it a push (spin) from the side, it started turning, but at a slower speed. hardly any air blows from vent. Will capacitor replacement solve the problem? Is slow speed also due to capacitor?
