Why won't the compressor run

This can be for a variety of reasons. It ranges from something as simple as no supply power (blown fuse, open breaker, faulty contactor, or run capacitor) or it could be more serious as a grounded or open winding in the compressor motor. My suggestion to any novice and or person without proper tools and knowledge; First check the low voltage (24 volt control voltage) by turning on the "Fan on" switch located on the thermostat to on, not "Auto" The blower fan should come on, indicating there's 120 volt and 24 volt available. Fan doesn't come on is an indication that there's no control power. The next step would be to check for power at the transformer and fuse located in the air handler. There should be 240 volts feeding the transformer, and 24 volts coming out. The control voltage is needed to operate the thermostat (which is the switch that sends the 24 volt signal to the compressor contactor to turn the compressor on/off. This 24 volt also powers other relays and switches in the system. knowing that 24 volt is available also tells you that the problem is most likely in the condensing unit (outside, where the compressor is located). At the condensing unit you should check for 240 volt supply power. Upon finding 240 volt supply power the question now becomes whether or not the thermostat is calling for anything (cool or heat if the unit is a heat pump). There should be 24-30 volt available at the small gauge wires feeding the contactor coil. While having the thermostat set at a temperature lower than the current room temperature (in the cooling mode) the thermostat should send a 24 volt signal to close the compressor contactor and turn it on. The non-metallic end of a screwdriver can be used to depress the moveable part of the contactor. After pushing in the contactor, should the compressor start then you may only need a new contactor. It may just hum because of a faulty run capacitor or grounded or shorted internal motor windings (grounded or shorted windings are usually indicated by tripped circuit breaker and/or blown fuse). It's a good idea to have a good multi-meter and knowledge of use before attempting any repairs or diagnosis on your own. I recommend some basic knowledge of electricity before even thinking about attempting any repairs or diagnosis.

My fan on my trane a/c unit is not coming on outside

Is it just the fan or the compressor as well? Check the breakers at the main panel. If the compressor is running but not the fan...It's a bad fan motor, but I doubt it.

If you have a volt meter, check to see if you have voltage at the contactor, If you do, take a screw driver and push the contactor in, see if the compressor and fan runs. ( they run together)

The outdoor unit doesnt work for ac panasonic cs c9mkp,i have following the instruction on manual book.

After switching the indoor unit to cool, the indoor fan starts and the light flashes, lower the temperature setting to 16 degree centigrade. When the light stops flashing the outdoor fan and the compressor start, if not check the wiring connection going to the compressor contactor. Check if there is power supplying the holding coil of the contactor. If the contactor works, check the power on both contact points by using a volt meter. If the outdoor fan only works, you need to check line working pressure. If the standing pressure is low, compressor will not start.

No heat, no ac. Power apparently not getting where it needs to be. Checked the fuse in the unit (5amp) still good. I have non-fusable boxes located next to furnance inside (crawlspace) and outside unit....

Hi, you do have a power problem, that's for sure.If the indoor unit has a non-fused box, and condenser also, it would have to be at the main breaker. That's the only power source you have that supplies power to everything is the main breaker. If you are sure you have power to the main unit, 120 volts to the furnace, you should have a led light that's is on, and its either red or green. This will tell you there is power there. The 5 amp fuse is for the secondary control voltage, 24 volts.If you could unplug your furnace in the craw space and plug something else in to check for power, you would know for sure. You may just have a faulty thermostat. If you turn the switch, fan switch to on, it should come on. If not, you have lost power. If you have a volt meter, this would be very helpful. You could have a bad transformer, but normally the 5 amp fuse will blow to keep the transformer from blowing out. I would check the fan switch, turn it to on and see if it runs, if not, you have lost power at your indoor unit. Make sure the panel on the indoor unit is put on right, as most of them have a panel switch on the perimeter that closes when you put it on to restore power. If its not on just right, it will keep the switch open, and you will have no power, so double check that panel. Check the led light, door switch, power to the indoor unit, and let me know what you find. It should be pretty easy to find where the problem is, if you are in the heat mode. This eliminates the outdoor unit, so you will know it is the indoor unit. Please let me know and keep me posted. You will find it, its a easy fix.

Unit will not start up evaperator fan runs

Hi, if your indoor unit is running and you have high voltage to the outdoor unit as the compressor runs, I would check the control wires at the indoor unit, coming from the outdoor unit, and from the thermostat terminals to see if the condenser is wired correctly. I'm not sure what relay you are jumping out to get the compressor to run, and no fan, but if you look at the contactor where your high voltage leads connect, you can energize the contactor by pushing down on the plastic part of the contacts and the outdoor unit fan and all will start. Carefully, use a insulated screwdriver, or I have pushed them down with my finger to see, but be careful! You do have high voltage there or the compressor wouldn't have come on. If all runs when you do this, the thermostat control wires to the contactor have no 24 volt control voltage to it. Check your red and yellow wire connections. If you have a meter, check across the 2- for 24 volts. If you have no low voltage, this is your problem. Go to your indoor control section. If this unit has a circuit control board, look for a plug in type fuse like you would find in your car, a 3 to 5 amp fuse. Make sure its not blown. If the led light is on, it will be good. You have lost the low 24 volt power to run the outdoor unit. Check the wiring there, Red and Yellow. Make sure they are terminated. If none of this helps you or your not at ease doing these checks, call out the contractor and tell them that the outdoor unit will not run if it is new and just installed. They should have done a start up on it. Check the contactor first by pushing it down, it will spark but don't jump as it may scare you some. If all runs, check everything I have told you and you should find the problem. If you have any questions, contact me through this site by my user name, shastalaker7. Keep me posted.

I have a samsung silver nano...the indoor unit & the outdoor unit fans are running...but there is absolutely no cooling. Any idea why?

  • Ensure Air Filter is clean - clean as necessary
  • Ensure Evaporator coil is clean - clean as necessary
  • Ensure Condensor coil is clean - clean as necessary
  • Inspect all wiring inside the unit for any loose or damaged connections - correct as necessary
There could be a failed compressor relay, run capacitor, or compressor motor/valves. Of course, it could also have lost it's refrigerant charge.

Without being onsite with toolbox in hand, I hope you find this information to be very helpful moving forward. :-)

Fan doesn't turn

Check to see if the fan motor has a separate fuse, if not then check to see if it has power (120 volts ac) with a DMM or volt meter. If it does then the fan motor needs replaced, if it dosen't then the fuse needs replaced or if it doesn't have a fuse, check to see if the switch is working correctly.

If you don't have a DMM or volt meter, or you do and don't feel comfortable testing it, then you'll need to have n a/c repair technician come out or take it into them if its portable.

Goodman ac unit is not cooling

If your uniy is not producing water then check if the compressor is running. Whether you have a central or a wall unit you will hear the compressor come on. There is a way to check the compressor by removing the compressor cover and wires then ohming out the compressor terminals. REMEMBER THE ORDER THAT YOU TOOK OFF THE WIRES. You,ll have run [R], start [S], and common [C] you should a reading across all three. If one or more do not show a reading then the compressor has an open winding. If all have readings then the compressor motor is ok. Check for burnt or broken wire which might have saw when you opened it. If the compressor is running then you are low on refrigerant.
