Having problems with your Air Conditioners ?

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!

Answers :

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 that is feeding voltege straight through to the motor. Your motor should have 1 black wire that goes to on side of the contactor 2nd wire should be white and it should go to the common side of the contactor (oppisite of the black) there should be 2 brown wires both of these should go to the capacitor. One of the brown wires may have a stripe on it if so it goes to the side of the capacitor that is marked if no stripe then it does't matter which side of the capacitor it connects to. Also check the contactor to see that the following hook up is proper. First the contactor has L-1 L-2 marking These are the voltage leads into the system from the power supply. Each side L-1 and L-2 should have 110 to 120 volts on each. Second on the top of the contactor there should be T-1 T-2 these are your terminal feeds the should feed the power to the unit and should have 110 to 120 volts respectivly. There should be 2 terminals at either side of the contactor that are your 24 volt feed from your transformer one connects to the left side of the contactor and one connects to the right side. This is the feed from the thermostat that signal the unit to come on. Good Luck on your repairs hope this helped you in some way

Goodman a/c j41 fan not running, turned off and on at fuse box, took a look at the box next to a/c unit and opened the box on the wall and pulled the plug and pulled the plastic panel off, there is no fuses. So i put back together and turned the a/c unit on, now at thermostat the snowflake is no longer flashing, some cold air coming out of vents, but outside a/c unit fan still does not run.

First you need to disconnect all power. Try spinning the fan blade, if it spins freely, then try moving the shaft from side to side to see if there's any side play. If not then the bearings are OK. If there seems to be some drag when your spinning th ... Goodman CKL42AR42 Air Conditioner

Air handler fan running but AC unit is not. Reset ckt breaker off and then back on with no results. Went outside and checked fuse box near the AC unit. Inside box has two red lights with wording Line 1 fuse bad when lit and line 2 fuse bad when lit. In this case the Line 2 light is illuminated. Can you tell me what this is an indication of problem?

The compresser will not turn on, it is not geting any fire to it. checked the ac fuse and it is good and it has power, pull the relay out and the fan quits running so i take that as it is working.

Check your start capacitor and look for charded wiring. If you have just one capacitor it will have 3 wires on top of it and capacitors are either grey or silver can type or oval can type. turn off the power and remove the capacitor pay attention whe ... Air Conditioners

I have a 19yr old Ruud Achieva 9.I have no AC at all. I have checked large barrel fuses - they are ok. Contactor clicks and you can see a spark at the contacts. Fan works. I don't hear a spin up of compressor. compressor is really warm though... seems higher than ambiant temp. I don't see any bulging or leaking of the start capacitor.

The outside compressor and fan will not shut off. I have turned the thermostat system to Off and even to heat, but it will not stop. I went on a trip, increased the room temp to 80 on the thermostat and left. When we returned 2 1/2 days later, the coils were frozen and no air was comiing through the vents, even with the blower motor working. So I turned the unit to furnace and melted the ice on the coils, but had to pull the fuses on the outside box to get the compressor to shut off. Is there a

A/C not coming on. The thermostat is set properly to cool, the temp to 67. However, on the interior fan runs and it does blow cool air but seem weak. I went outside to the A/C unit, and nothing is moving. I checked the circuit breaker and the exterior fuse box, but nether are tripped. The A/C unit is a Goodman SSX 16 series.

When the thermostat turns off, the condensing unit continues to run. The old contactor was sticking. I could go out and tap on the side of the electrical box beside the compressor, and the contactor would drop out, allowing the unit to shut down. I have replaced the run contactor, but the problem has not gone away. In fact tapping on the electrical box won't even make it shut down now.

You most likely have a short. Start by removing the wire on the terminal marked y in the t- stat then see if it shuts down. Look in the air handler for wires touching together. I have also eound wires touching in the wall from the t-stat. ... Carrier 38CKC042 Air Conditioner

Our inside unit Coleman EB20B (outside unit Goodman GKL 49-1) keeps blowing the in-line 3 amp thermostat fuse. We've rewired the wires in the wall, rewired the contactor wires, and the contactor was broken so we replaced it. We're still blowing the fuse. Could we have reversed the thermostat wires at the contactor? Or could the short be in the Blend Air box-this box is coupled to the thermostat wires? Thanks Ken Rohm

Swamp cooler keeps blowing on low speed. Amp it out at the switch and it's only pulling 3.8 even with a lload also amp it at the cooler side and it's only pulling below 9 amps. No reason why, I do have an old disconnect box with two 15 amp fuses and I'm suspecting it. Icould the connections be bad in that box. When low fuse blows hight continues to work.

I have a comfortmaker unit with heat strips. The blower fan comes in and blows cool air. I have checked voltage at the transformer, and it is producing 24 vac. The contactor for the fan and condenser never pull in so I replaced the defrost control circuit board. Still only blows cool air and the defrost cycle never comes on. I jump 24vac to the coil on contactor and the defrost fan came on and the condenser came on so the fan motor and start/run capacitor are good. Any suggestions.

Have 3.5 ton scroll compressor, single phase, that will not run. Checked start, run, common windings all ohmed ok. Checked for case ground/short, none detected. Replaced contactor and capacitor with new. Still will not run. Force contactor closed to energize leads to comp and voltage is there, but comp will not kick off. Checked amp draw on incoming line is 4.5 due to only condenser fan running. If comp was locked amps would be very high and if internal wiring were shorted it would show open

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
