Having problems with your Air Conditioners ?
Fan will not start
Some things you could check first would be to make sure you got all the packing out of it. May just be something blocking the fan blades. Make sure you have the right power supplied to it. Probably 110v 60 cy with a ground which is the normal house plug in the USA. If that's not the problem, I would call the place you bought it from and tell them what's going on with it. If you don't get help there, call the manufacture. In most cases they will have you return the unit for a new one.

Furnace fan won't turn on sometimes. The fan will start and when house reach set temperature, fan turn off, and will not start again. On the control panel I move the switch from Auto to On and hear a loud noise for about 3 sec. fan will not start. I will wait for about two hours and the fan start right up. I have to do this each time.

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
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!
My sheet shows part # 3100248.420 as fan run capacitor.You may have an updated number. Check voltage outputs labeled on it are same as on old one, and double check wiring is correct, to and from capacitor. Be careful not to mistake compressor start c ... Dometic Rooftop RV Air Conditioner
My compressor unit outside runs and cools Freon but the inside blower has a problem running. the model # is 2TEE3F31A1000AA. The fan control, in fan run control mode, shows a bright green for the fan LED and the CFM selection LED varies with the rotational speed of the fan. The motor tries to start showing , initially, a jerky back & forth movement. It squeaks some and may, or may not, start rotating. If it starts the CFM LED goes bright/on no flicker and the motor runs briefly (5 seconds) then
Hi, from what you have told me, you are loosing the bearings in this blower motor along with windings. This motor is rubbing the blower housing, tight when you turn it, and when it jerks when it tries to start tells me that you have burned or very we ... Air Conditioners
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
Amana Portable AP125D mine is doing the same thing as another person said i noticed the exhaust fan would occasionally start to speed up to fast go into warp , then start banging around. i stopped using it, before the fan broke up, but unsure what the problem is. or what needs replaced. the blower fan or some circuit controller? and no nothing was dropped into the fan . its been it the same place and never moved.

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.

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. I can manuelly, start outside fan by using a long screw driver to turn the blades. Then the fan begins to turn slowly until it reach a faster speed. But I do not beleive that the fan is turning as fast as it use to. I go back into the house and after 15 to 20 minutes the temperture has not dropped. It apprears to stay a th

The AC unit turns on and I can cycle through the options in order to adjust the fan speed however the fan does not start in any of the three settings. The ac unit produces cold air, however the fan does not run. The unit sounds like it trys to get the fan to start however instead of blwing air it produces a funny smell. Any suggestions?

I have a goodman 2,5 ton outside unit, i cant get the compressor to start even with replacing the start capacitor and using a super start on the compressor side of the capacitor? normally i wouldnt have a problem with this kind of repair but im getting power feed back through the cooling fan motor even with it unhooked from the start/run capacitor enough to start the fan slowly. i havent seen this before
Check to make sure you have 220 on both sides of contactors, double check wiring at capacitor. you can also check continuity between all three post at compressor , make sure power is off and wires are disconected, if you do not get continuity between ... Goodman CLQ36AR49 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
Turn the unit on, the fan runs, and when the compressor tries to start the fan slows down and the compressor will not run. After a few seconds the fan speeds back up. I put an amp meter on the compressor lead and when it tried to start I registeres 41 amps. Is this a compressor or capacitor problem?
Sounds like you have a bad capacitor, if it's not tripping the breaker it doesn't sound like the compressor is drawing LRA unless the breaker is oversized for the condenser. ... Air Conditioners

The condenser fan does not come on when the compressor starts. When the system calls for cool air the compressor starts but the condensor fan does not. I replaced both circuit boards and the condensor fan motor.

Fan will not start. Sounds like it is coming on, I see the relay pulling in for the unit, hear it start up, but the fan will not start.
You will need to check to see if fan leads(black and white) are getting there voltage at the top of the contactor. it should have a 5mfd capacitor to the left of the contactor make sure both leads are hooked to it. More then likely the motor needs to ... Air Conditioners
I have a Coleman Evcon gas furnace model# DGAT095ADA last year I replaced the T-O-D #60T82 - 313675 fan switch and works fine. This year the unit started fine, but slowly started taking longer & longer to heat up, then finally not heating up enough to trip fan switch. Manually tripping fan switch resulted in some warm air through system, but not enough to heat a house. Gas comes on and is blue what would be my next course of action ?

Coleman mach fan runs fine but A/C hums intermittently like it wants to start but won't. I'm running it with a Honda 2000 generator. Generator ran out of gas, when I restarted the generator the A/C would not run - stalls out the generator. I replaced the start and run capacitors on the A/C, hook up the generator and it ran fine until the generator ran out of gas. The A/C would not start up only hum intermittently - same problem as before replacing capacitors. Waited several hours with the fan on
The issue with the generator that gets low and high when it start running out of gas that effect the A/C and result of high voltage getting to the unit and burn the capacitors and it should by saved by the fuse make sure that the gen not run out of g ... Coleman Mach III Air Conditioner
