I pulled the wire to the thermostat (inside house) out of the compressor unit outside with the weed earer. It is not obvious where to re-connect it. Where do I connect the wires (white & red)? Amana (Goodwin Co.) Model#:ASXC160361BA Serial#:1005063215

    I was expecting to find this relay. It's not there. There is a rather complicated looking circuit board instead. The circuit board seems to have been made by Emerson Climate Tech. The words "Climate Talk" and the number "4672H" are printed along the top edge. There is also a Bar Code sticker affixed to the circuit board that bears the number 11014630400034. Again, where do I connect the thermostat wires (red & white).

Air conditioning condensor will not run from thermostat have to go outside remve covers and jump thermostat connection . Then runs fine and cycles problem is intermitant


If it was me I would make sure the weed wacker hadnt attacked those wires as they leave the area leaving the house making their way to your condensing unit. Next, follow those wires back to your furnace control terminal area. Blower vibration can cause those little wires to break over time. Take care not to cause a break. Next, pull the thermostat off its base wall mount and jumper the red and the yellow wire, sometimes there is a blue color wire instead of yellow. If the unit outside comes on after this trick, make sure rc and rh are jumpered together on the thermostat terminal base and if they are then its your thermostat. One last thing, if someone has changed that thermostat since last cooling season, the thermostat wiring should be red to r terminal, white to w, green to g, blue or yellow to y terminal. Again rc and rh are usually jumpered. There are exceptions and at the very least see that the red wire is under the rc terminal.

Furnice air blows, but my ac unit outside want cut on


if the inside unit is running but the outside unit isn't - I would check the fuses or breaker. I suspect you have a blown fuse or a tripped breaker.
What is also possible is that the 'low voltage' thermostat wire (coming from the thermostat inside the house) has been cut - possibly by a lawn mower or weed eater - or chewed into by a dog.
If this is the case - you easily splice (with all power off) the wires back together using the color of the individual wires.

Make sure none of the thermostat wires from the inside unit to the outside unit have come loose or have be cut by a weed eater or such. These units are a little more complex than your average heat pump.

Outdoor unit fan is running when turned of inside? is this normal?


No. The thermostat (located in the house) controls both the inside and outside units.

A common problem for the situation you're describing (and the one I will explain here) is that the contactor (located in the outside unit) which is controlled by 24 Volts coming from the 'inside' thermostat - has 'stuck' in the 'made' position (causing line voltage to remain to the condenser 'and' possibly to the compressor).

To 'determine' this - 'turn off the line voltage to the outside unit.'

You do that by locating the 'breaker/fuse box' which is located near the outside unit. It will be a gray box about the size of large cigar box - and will be attached to the side of the house usually - although it can be on the AC unit itself.


The lid can be lifted which will expose a 'breaker switch' which resembles a light switch (sometimes a little larger) which can be flipped in the OFF position.

If it's a 'fuse block' - then you will have to grip it and pull it out. Usually there will be a metal ring that you can grip and pull. Once the 'block' is out - you will notice that it contains two fuses.

Either way - once you flip the switch down or pull the fuse block - the line voltage is disconnected to the AC.

NOTE: some 'older' breaker boxes contain 'knife connectors,' which are designed to 'disconnect line voltage' by the action of 'pulling a handle (on the side of the box) ... down. When this handle is pulled down the 'knife connectors' will 'disengage - thus disconnecting the line voltage to the AC unit. "It is not uncommon" - for 'one' of these 'knife connections' to remain in the "connected" position - which will still leave partial line voltage to the outside unit - a potentially dangerous situation.

Point being - it is always wise to check the voltage coming in (with a voltmeter) before sticking your hands into a electrical device like a AC.

That being said - sometimes after turning off the breaker switch (or pulling the fuse box) you can hear a 'buzzing noise' coming from the outside unit. If you hear this noise - it means you are still getting 24 Volts from the inside thermostat. However, in this case, assuming the thermostat is indeed OFF - then you shouldn't hear any buzzing noise.

Either way - when you turn the breaker off the unit will shut off. NOTE: be sure the inside thermostat is in the OFF position.

Then you can open the electrical panal of the AC unit and take a look at the electrical components. NOTE: as stated above it's always 'wise' to use a voltmeter and "make sure" there is no voltage to the unit. You are looking for 24, 110 or 220 volts.

The component (contactor) you are looking for is usually easily identified because the unit's main electrical wires (typically 3) are coming into the contactor from the breaker box.

This component usually has a small plastic front plate that can be removed by taking out a couple of screws. (Note: it wouldn't be unsual for this cover to be missing already)

Once the cover is removed you can see that this device is designed to 'connect' the wires coming in from the breaker box to another set of matching wires that sends line voltage to the fan and compressor among other things.

It is a 'spring loaded' device that is usually 'pulled together by 24 Volts coming from the inside thermostat - but by depressing it (manually with a screwdriver) will cause the copper contacts to "make" - thus - connecting the wires from the breaker to the wires sending voltage to the fan and compressor.

This is accomplished with 'spring loaded action.' Normally - you should be able to take a screwdriver (as stated above) and manually depress the contacts - but in this case - it - may already be - "made" - and you will not be able to this.

Usually if this is the case the copper contacts have 'burnt' together - and the connection is permantely engaged - which is what causing the AC to run (outside) even though OFF on the thermostat inside the house.

If the contacts have burnt and are permantely engaged - then the 'fix' is to replace the contactor - which can be accomplished by removing all the wires (from the contactor) - clearly labeling them so you can replace them on the new one.

Once you've removed all the wires - you need to remove the contactor from the unit. It will usually be 'screwed' into the unit with screws.

Once you have the contactor out you can take it to a Air Conditioning Supply house and buy a replacement part. I would try to get an identical contactor - to make it as easy as possible re-installing it and putting the wires back on it.

NOTE: I would not attempt this unless you are -very - "mechanically inclined." Changing out a contactor can be very complicated/difficult.

Also - 'paying a Service Tech to do this for you - shouldn't cost much - probably less than $100 (if you already have the replacement part).

Good luck!

Will not cool off house but fan outside is blowing


If the outside fan is running, (assuming the inside fan is too) then you can bet you have a compressor 'not' running. You know the fuses/breaker are good, otherwise, the outside fan wouldn't be running.

If you're lucky you have a wire burnt off the compressor and a honest tech will fix that for you - fairly cheap - probably around $150.

Or, you could do it yourself.

1) shut off all electricity to the unit, i.e. turn the breaker off or pull the fuse block. You'll find the breaker and or fuse block in the little gray electrical box mounted usually on the side of the house, but in any event somewhere close to the outside unit. If you're not sure - just follow the electrical conduit from the outside unit to the gray electrical box.

2) go to the compressor and pull the little plastic cap from where the wires all are. Usually this little plastic cap has a metal snap of some sort holding it in. But once you get the cap off - if you're lucky you'll have a wire burnt off one of the compressor terminals. If that's the case - all you have to do is get a new connection back on the wire and slide it on the vacant terminal.

Note: it's possible to have 'two' wires burnt off - in which case it might be a little more difficult - because then you will have 'two' vacant terminals. At this point it might be wise to get a service tech to help you out - to make sure you get the wires back on correctly.

3) once you have the formerly burnt wire back on the compressor terminal - you just need to be sure the new connection is 'tight.' Remember when it comes to electrical connections - 'make them tight,' otherwise you'll have problems.

4) put the breaker back in the up position or insert the fuse block back in - and turn the AC back on using the inside thermostat.

5) if it's not a burnt (off) wire - then my guess is you're looking at compressor problems and it's time to call a service tech.

good luck!

Ac unit will not come on


pull the fuse/breaker disconnect panel outside by unit and main breaker inside,remove compressor access panel,re-power unit trace your thermostat wires to the terminals by compressor and short the two term together and see if unit starts,sounds as though you broke wire in more than one place.good luck be careful doing this,its 240 volts at most compressors on a central A/C

House HVAC Not Blowing


If the outside unit is running and the inside unit is not, probably a problem with the fan motor itself or its capacitor. If you have to have someone repair or replace the fan $200-$250 with parts, a capacitor for a service call and part $100 or so. Check it yourself first to see if there is anything obvious broken wire, hot connection, etc if you feel safe doing that. Turn the power off first. There is also a chance the thermostat could be the problem. Have you tried running the fan on the thermostat "fan on" setting?

The fan is working but the air conditioner unit is not working


Lets take a moment to see what exactly is inside the condenser (that's an outside unit) You have a compressor, a fan, a contactor, a coil, and a capacitor. How does it work? The condenser is connected to the house via an electrical box called a yank out. It is a quick way to kill power to the unit. Note: this is not the breaker to the unit. That would be in the main panel by the meter. People always assume this is the only safety. It is put there by law to kill the power to the unit for service personel. Pull out the connection to kill the power before checking the unit. The first thing to look for is a swolen capacitor failed%20cap.jpg. If it swells it fails and the unit don't function too well. The next thing to look for is contactor problems. Their are small wires coming from the inside control panel that power up the 24 volt coil that yanks down the contactor. That coil might be bad. If it has no continuity(open) it is in need of replacement. A critter could get between the contacts and fry them as well. Look on the compressor for burnt wires and loose connections (very common). The fan motor should be very easy to turn so if it is stiff then it probably is in need of lubrication. The standard oil in the HVAC world is Zoomoil. It is hi temp resistant, will not lose viscosity and is non flammable. If a weed eater should kill the thermstat wires going outside noting will work because the contactor won't pull down. if the contactor coil is open then it won't pull down and engage the compressor and fan. if a critter crawled under the contacts nothing will happen. of course if the compressor pins are shorted to the copper piping or there is a hole in it or it has an open winding between pins it is shot.

AC breaker trips after 10 minutes


Whats the amp breaker? Is this for the inside unit or the outside condenser? If the inside and gas heat you have a bad fan motor, If its an electric furnace , the same, but if its the outside unit, the fan could be going bad, locking up and the compressor still runs and pulls high ampsand tripps breaker or the compressor is just pulling too many amps due to plugged coils with dirt , grass or weeds blocking airflow.(koolbreezes74401@yahoo.com)
