Having problems with your Air Conditioners ?
Condencer unit fan wont run
Turn OFF the power. Check to see it the condenser fan will spin freely. You should feel no resistance if you spin the blade manually. If it is tight change the motor. To check the power to the motor remember 220 volts CAN KILL YOU if you do not know what you are doing. If you are safe for this use an amp probe or a volt meter to see if you have power going to the motor. You can check this at the contactor. If there is power to the motor and the motor doesn't start its either the motor or the capacitor. If you do not have power to the motor it could be your contactor, your disconnect box or your line voltage.
If you have power to the fan and the fan won't come on, then its bad. You don't have to do another check. You will know if the capacitor is bad by turning the power on to the unit and taking a stick to start the fan. If the fan starts running after manually spinning, then the cap is bad. If not, the motor is bad.

Im working on a old Rheem pac unit with a faded model and serial number! When I arrived the condencer fan was running real slow and nothing else! One fuse was burned out in the pull box! The contactor was in very bad condition so I changed it! Now the fan runs still runs slow and its running with out the contactor engaged and when I ingage the contactor it blows the fuse!
Fan motor is going out or the capacitor to the fan is bad I suggest replacement of both the fan motor and the capacitor which should always be done any time you replace the motor. Also check your wiring again you have a wire connected to the fan tha ... Air Conditioners
I get heat, but its now time fr a little A/C and the "condencer nits inside the outside fan unit are completlet covered in ice. I turned the units off and the ICE/FROST cleared out in about 1hr...I tried running it cool again and it only took 10-14min for the lines and the condencer nits to freeze up..n air came out of the vents?? had the unit 5 years with NO isssues at all...any thoughts or idea?
A system restriction can cause freeze ups. This usually either happens at one of the driers (looks like a cannister) or on a capillary tube if you unit has one. The capillary tube is a 1/8th inch line. What you can try..is tapping on cannister of ... 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
\011Sound more like the cap, but if the motor is raging hot, it could be the motor, another thing it could is improper voltage although less likely. But Goodmans/ do have this weird fan relay issue were they just bite it some times. I wo ... Goodman Air Conditioners

Trailer sat in a monsooon storm last night. next morning compressor kicks on just fine and motor hums but fan wont spin unless i jiggle the wires? did somethning just get wet and needs to dry out or did it short out my run capicitor? Help?
If you have to jiggle the wires going into the compressor motor to get it going, I would submit that you may very well have a broken wire or otherwise loose connection that is making contact when you jiggle the wires. If all appropriate connections w ... Dometic Rooftop RV Air Conditioner

Help... My problem seems to be my furnace works fine if i manually cold start it but once my unit gets hot it wont restart the jets wont stay lite and the fan will not come on but if it hasnt been running and is cold its starts fine ???
If you were experiencing a failure just after a heating cycle but not on a cold start, I would suspect an electrical component failure. As the component cools, it makes contact and allows the furnace to operate. This will change and not for the ... Air Conditioners

I have a Sanyo Split System the indoor unit is a KHS0921 and the outdoor unit is a CH0921. When i first turn the indoor unit ON the fan will run for a few minutes and then go off. The outdoor unit never comes ON when there is a cll for cooling. The only way to get the fan to come ON again is to turn the breaker OFF and then back ON. The Operation loght will come ON when the fan is running but it will start flashing when the fan goes OFF. What should i look for?

Friedrich YM18 230 volt heat pump. The unit has heated and cooled well for about 5 years. Just started heating mode recently and the unit no longer heats. Fan runs OK. Was able to get the heat strip to run for a few minutes (smelled the dust accumulated over the summer burning off). Now, no heating whatsoever. When in the "Money Saver" mode, nothing happens. Fan will not come on and unit will not heat. With "Money Saver" mode off, the fan runs.

My AC unit is not blowing cold. I have two. One small and one big . I just noticed that My upstairs was not cooling off. So I turned both units on and went out sid to check them. The small one is running fine fan blowing cold freon running through. The big was not running at all. I sprayed them off and while doing that the fan on the big unit began to turn. Now it is running but every now and then it keep making a noise like a motor is trying to turn on. and the freon line is not as cold as the
The start capacitor is in question and the fan appears to be overheating, That is where the water camre into it. You may need a HVAC tech to make your repairs. Good Luck _Ned_ ... Air Conditioners
This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.
You have a bad board or bad switch. I would say board. You can have service tech check this out. There is only so far you can go without knowledge of Controls ad electricity. Russ ... Air Conditioners
