Question about Heating & Cooling

1 Answer

The Dual capacitor went out and I replaced it with the same numbers listed on the side. I went to set the temperature and turn it on and it will not even turn on. The thermostat has power, but the A/C unit will not turn on. Do I need to wait awhile for it to work?

Check the power to the outdoor unit it may be off...

Also the t-stat will have a five minute time out...

How to wire Dayton capacitor E136401

It appears this is a 7.5 microfarad (mfd) capacitor like the ones installed on fans. If your fan motor has two brown wires, in addition to the black and white power wire, just fasten the two brown wire to the leads on the capacitor and insulate the connection with electrical tape and mount the capacitor in some dry convenient location inside the controls section of your unit. Be carefull to mount the capacitor in a location where it does not short an electrical connection.

If the capacitor is replacing the low side of a dual capacitor, for example a 35/7.5 capacitor, extend another lead from the common side of the dual capacitor to one side of the 7.5 capacitor and place the one brown lead from the fan motor to the other lead on the capacitor. If trying to replace the lower side, it is better to just replace the dual capacitor.

Just blows straight air

First thing I think of it the capacitor that operates the Fan and Compressor is just working on the fan side. These Capacitors are dual type. Locate the capacitor and after you shut down the electricity remove the wires and mark them so you know which ones go where. Take to parts house and they can fix you up with a new one of right size and style (either round or oval) make sure they test the capacitor there is one more thing it could be but taking a guess the unit is relatively new. if not the problem get back with me Ken

The outdoor fan is turning slow. it sounds like the compressor wants to kick on but it wont. the motor is really hot. what could this be

Sounds like a bad capacitor for your fan motor. You can test that by following the procedure listed below.

***CAUTION*** Anytimeyou are working on or around electricity you run the risk of shock and ordeath. Please consider consulting an expert before you open an electrical panelor appliance. ***CAUTION*** Capacitorshold a large electrical charge and will discharge upon contact with your skin.This is enough to stop your heart and cause death. If you are not confident ofyour abilities around these devices then please leave any testing or repairs toa professional. The capacitor is inside the unitand you have to remove the cover to see the inside of the electricalcompartment. You will need to discharge the capacitor before you start workingaround it. To do this take a screwdriver or other long metal tool with aninsulated handle and cross the three terminals on the capacitor to ground. Youthen remove the wires to the capacitor terminals, taking note of which wiregoes to which terminal. Capacitors are rated in MicroFarads (marked by a µF symbol) and a dual capacitor, shown in the image below,will have two ratings listed like this "35/5µF" or something verysimilar. You must have a multimeter thatreads micro farads to check a capacitor. You do that by placing one probeon the C or COM terminal and the other probe on the FAN terminal and it shouldread the small number of the rating, for example if your capacitor is ratedlike this: 30/7.5µF then the fan rating will be the smaller of the two numbers.In this case the 7.5µF (seven and a halfMicro Farads). The HERM terminal is the one for the compressor and will berated the higher of the two numbers, I.E. the 30µF on the capacitor. Check themboth and of they are more than 6% lower than they are supposed to be then thecapacitor is weak and needs replaced. If you read 0 (zero) then the cap is badand needs replaced.
Typical dual run capacitor C terminal is common, HERM terminal is compressor and FAN terminal is for fan motor.

P291-3554RS dual cap is the Carrier part that is called for.

Are you talking about a start capacitor or a run capacitor?
Usually a dual capacitor is a metal can type capacitor with 3 terminals.
C - which is run for compressor and fan.
Herm - is start for the compressor.
Fan - is start for fan.
A start capacitor is a black plastic capacitor
It is in series in the run wire to the potential relay, one side goes to run on the run capacitor and the other side goes to #1 on start or potential relay.

Fan isn't turning

turn the power off, take the cover off the top and try to spin it. If it spins hard then it was the motor. If it spins easy the the capacitor is probably bad which
would cause the fan to go bad.

Usually this can be a dual capacitor which also controls the compressor. Sometimes just replacing
the capcitor can do the trick, if not then the worst
is that you will have to replace the motor and still use the new capacitor

My VP930B monitor screen is so distorted that you can barely see what is there. Once in a great while the picture will suddenly be perfect! The monitor and tower both have a DVI-i dual connectors , but my...

Could be. You can try using the VGA port just for a test. Connect it to a friends computer or a laptop. also, there is the following solution for unusual problems on the VP930B:

It is caused by bad capacitors in the power supply circuit.

Open the monitor, and look at the power board. There are six capacitors. Replace the 220uF @ 25V and the 1000uF @ 16V capacitors. I would recommend replacing them with 35V and 25V capacitors respectively.

If the serial number on your monitor starts with Q8H you could also have a bad IC on the main board. Q8 on the main board is an FET in an IC package. If this problem persists solder a wire from the right side to the left side. There is one pin that turns the IC on and off. All the other pins (per side) are soldered together. Do not solder the pin on the left side that is by itself. Just leave it. Solder ALL the other pins on the left to ALL the other pins on the right.

Remember, do this ONLY if the problem persists after replacing the capacitors AND if your serial number starts with Q8H.

Replacement of air conditioner's compacitor

I am assuming this is a split system with the condensor outside and the air handler inside. What is the model of your unit? Is the capacitor a dual run capacitor? Is the compressor running? If the compressor is running and your condensor fan is not you need to immediately shut power off to the compressor or you will probably ruin your compressor. If the power went off due to a storm and you don't have power to the condensor fan did you check to see if the circuit breaker to the condensor was tripped. I would check that first. Even if the circuit breaker doesn't look like it tripped go ahead and flip it off and back on again. Even you suspect it is the capacitor you need to determine if it is a dual run (controls the compressor and the fan) or does it just run the fan? If it is a dual run capacitor you will have to get the numbers off the capacitor and try and find a match at the local hvac supplier. If you have a Grainger's in your city they probably will have a match. When working on your unit don't forget you are working with high voltage that can KILL you, If you don't know what you are doing call in a professional. If you decide to tackle it yourself make sure you turn off the power to both the inside unit and the condenser. I always pull the disconnects inside and outside, flip the circuit breakers and turn off the thermostat just to be safe. Then I double check by using my digital multi-meter to ensure the power is totally off. The capacitor stores power so you will have to discharge it by using an INSULATED screw driver and touching the blade across the terminals. Discharge the capacitor AFTER THE POWER IS SHUTOFF. Before you pull the wires off the capacitor terminals I suggest you make a drawing of where the wires are connected. You should have markings with a "C", "F" and "Herm". Even better, I like to take several digital pictures from different angles of the connections. After you remove the capacitor, I would suggest you take it with you to your hvac parts supplier so they can match it. Once you get the right replacement capacitor it is just a matter of connecting the wires back to the original configuration. Then restore the power by flipping the breakers, plugging the disconnects back in and turning the thermostat back on. Most units will not start up right away. They have a 5 minute delay built in to protect the compressor. Good luck and post back and let us know how it goes.

2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

I have a ruud model number upne 060 jbz the compressor is not coming on .could it be the capacitor?

It could be, could also be lots of other things. Is the indoor fan comming on? do you have 240 volts at the contactor? both sides of the contactor? Is the contactor pulling in? Is there 24 volts on the low voltage side of the contactor? is there voltage at the compresser? Did you ohm out the windings?
