Alot thing there...
* Outdoor condensing fan motor has stopped running. This problem could be caused by a bad motor run capacitor. Please see our Run Capacitor Page to purchase a new capacitor. Here is a link to our capacitor page: Motor Run Capacitors. If your motor capacitor is not the problem, then more than likely you need a new motor. Is the fan blade tight, stiff or hard to turn? If the fan blade is hard to turn then you probably need a new motor.

* Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run. The compressor is locked and will not start. What is happening is the compressor is trying to start, but because the compressor motor is locked it tries to start for a few seconds and then because of the high amperage being drawn goes off on internal overload. The internal overload protects the compressor windings from overheating and burning up. I see this many times during the start of the air conditioning season. Some compressors just have a hard time starting after sitting all winter long. Some compressors are locked up so bad that I can not start them and must tell my customer that they need a new compressor or new air conditioning system. Many times I can get the compressor started again without having to buy a new compressor or new air conditioning system by using the device that I sell below. It is called, "Super-Boost." I keep two or three of these on the truck. They have saved many of my customers from having to buy new air conditioning systems. The Super-Boost could save you from having to purchase a new air conditioning compressor or system!

* This problem is probably the second most common problem that I see every summer. The problem is a bad compressor or fan run capacitor. The Air conditioner outdoor unit will not come on. Either the outdoor fan does not run, the compressor does not run, or both the fan and the compressor do not run. You checked and reset your breaker and the outdoor unit still does not come on. You can hear a little humming sound, sometimes a "Uggg" inside the unit when power is applied. The "Uggg" is the compressor trying to start. You might hear the low voltage contactor humming. You pull the disconnect and disconnect the power to your outdoor air conditioning unit. Please make sure your electrical power is off before working on any air conditioning equipment. You take the door or cover off your outdoor unit's control box and find a bad, swollen run capacitor. EPA stopped allowing manufacturers to produce capacitors with cancer causing PCB's. Since they stopped allowing the use of PCB's the capacitors now have a shelf life. Many times I see capacitor problems that will not allow the compressor or the fan to come on. Many times you can clearly see that the capacitor is bad because it is swollen or even blown apart with capacitor oil everywhere! Sometimes you need a special meter to test the microfarad (MFD) rating. Most of the time you can tell the capacitor is bad because it is swollen up.

* Air Conditioning outdoor condensing unit or heat pump unit will not shut off. It continues to run no matter what you do. The only way you can get the outdoor unit to shut off is turn off the breaker or pull the outdoor disconnect. Also, sometimes when the contactor fails the outdoor condensing unit will not come on at all. Dirt or insects (I see ants many times) can get in between the contact points while the contactor is off, and cause the air conditioner not to come on at all. When the contactor is stuck in the "On" position (contacts welded together), Ice will form on the indoor evaporator coil and all the way out to the outdoor unit. I have seen 1 or 2 inches of ice form on the line set and outdoor unit compressor. You will not get hardly any air flow through your duct work when this happens because the evaporator has become a complete block of ice. If this is your problem then your contactor points could be stuck, welded together causing the outdoor unit to run continuously. Many times when ants or insects get between the contactor points the outdoor unit will run (burns the insect out), but because of the uneven wear (arcing) in the contact points the contactor will soon fail. Arcing causes a tremendous heat build up and pitting of the contact points. If you are in an area of the country where insects are prominent in and around air conditions, then I would suggest you blow your contactor out with compressed air or check and make sure you do not have any insects in between the contactor points at the beginning of each cooling season.

* Compressor will not run. First, you turn off the power to the air conditioning system. Second you remove the compressor terminal cover and find that one or two of the compressor terminals have burned completely off. Yes! that is why the compressor is not running!
SOLUTION: Remove the old burnt terminal/terminals, and use the "Term-Lok" compressor terminal repair kit to replace the burnt terminals and wires.
The "Term-Lok" compressor terminal repair kit is one of my favorite items to have on the truck during the summer time. The "Term-Lok" compressor terminal repair kit has saved many of my customers from having to purchase new compressors or air conditioning systems. I see many, many burnt compressor terminals during the course of the summer. Many contractors will tell their customers, "You need a new compressor or new air conditioning unit." Most of the time this is not true! All you need to do is use the "Term-Lok" kit to repair the compressor terminals and you are back in business for a long, long time. Before I found out about the "Term Lok" compressor terminal repair kit I would try to solder the terminals on using a soldering gun. I found out the hard way that the solder would not hold but for a short period of time. Before long, I would get a call again, "My air conditioner is not working." I would go look at the compressor terminals, and there again, one of the terminals or terminal was burnt completely off again. I could not believe it! Since I have started using the "Term-Lok" repair kit, I have not had one call back for burnt compressor terminals! This new Term-Lok compressor terminal repair kit is not cheap, but it is much better than having to get a new compressor or air conditioning system. This compressor terminal kit costs $40.00. I figure the kit is so expensive because of the brass terminal connectors and the way they have permanently connected the #10 gauge wires. What I really like about this kit is that it lasts!

* Nothing works on your heating & air conditioning system. The fan will not blow in the fan "ON" position. The gas burners will not light, the outdoor air conditioning unit will not come on.
SOLUTION: Use a Volt Ohm meter, set the meter to "Volts AC," to check and see if you are getting between 24-28 volts between your "C" and "R" terminals on your low voltage board, or between "R" the red low voltage thermostat wire and ground. You might have to tape the blower door safety switch, to keep the voltage on so you can perform this test. Turn your power back OFF after completing this test using the Volt meter. Check for fuses on the furnace control board to see if the furnace has a low voltage protection fuse. If the furnace has a fuse pull the fuse out and see if it is blown. If the fuse is blown check all your low voltage wiring to make sure it is not grounding out anywhere. I have seen pinched wires that are stuck between furnace doors, animals that have chewed through wires and just weathered low voltage wiring that has lost its insulation due to the hot sun over the years. Any wires that are touching together can cause the low voltage fuse to blow. The fuse protects the expensive furnace control board from getting burned up because of a short to ground. If the fuse is blown then I would go to the local hardware and purchase 5 to 6 new fuses. If you do not find the problem that is causing the fuse to blow right away then you will need more than one fuse for testing. If your fuse is OK or your furnace does not have a fuse, and you are not getting low voltage between the "C" and "R" terminals then you might need a low voltage transformer. I have seen some of the transformers just go bad.

    * You might consider purchasing and installing the following device if:
    1. You have to reset your air conditioning circuit breaker often.
    2. If you have electrical storms where the power is going off and on. Please always turn your air conditioner off during a storm.
    3. If the power goes off and on often in your home. If the power goes off and on often in your home then this can ruin a compressor. When your air conditioner is turned off you should wait at least 3 to 5 minutes before you turn it back on. If you do not wait the 3 to 5 minutes then this causes a tremendous strain on the compressor motor because the motor is trying to start without the pressures being equalized. Please give your compressor and air conditioning system time for the pressures to equalize before starting your air conditioner again.
    4. If you have children living in your home, renters, or other people who do not understand that you should wait 3 to 5 minutes before cycling and air conditioner off and on.
    SOLUTION: Purchase a delay on make timer pictured below. You can set this timer to the length of time you want to wait for the air conditioner to come back on from .03 of a second to 10 minutes. What this timer does is delay the amount of time you want your air conditioner to come on when low voltage power is applied to the timer. This low voltage timer is simple to install. *Some of the new thermostats have this delay feature built into them. If you have a thermostat that has this delay feature, then you do not need to purchase the Delay On Make Timer pictured below. If you want to protect your air conditioning system from short cycling and possible compressor damage, then the Delay on Make timer is for you! Please remember to turn off all power when working on air conditioning equipment.

    * Air conditioner is freezing up. You see frost or ice on the suction line (black insulated line) Any areas that are not insulated are covered with ice. You are not getting hardly any air flow out of your registers. Your evaporator coil is iced up completely. Most of the time this is caused by being low on refrigerant charge. There are other causes such as:
    1. Dirty air filter or some air flow restriction.
    2. Dirty blower
    3. Slow or dragging blower motor (might need a new capacitor).
    4. Dirty stopped up Evaporator coil (Need to have HVAC tech clean coil)
    5. Long Air conditioning run times. Setting thermostat below 72 degrees with cool outside conditions.
    6. A stuck contactor that keeps the outdoor unit running even when the indoor blower is not running or when the thermostat is calling for cooling. We sell contactors above.

    Most of the time a freeze up condition is caused by a low refrigerant charge. Since the air conditioning system is supposed to be a leak free, sealed system this means you have a leak somewhere.

    Hope helps.

No power to my wii. outlet is good.


Try the Wii in another working outlet just to see if it turns on. If it doesn't then try another AC Adapter in the Wii. If it still doesn't turn on with a new AC Adapter then that means the mainboad is bad inside of the Wii. If the Wii turns on then that means your old AC Adapter is bad.

Wii won't turn on


Hello :


Most power problems with the Wii can be fixed by resetting the [AC] adapter. You can easily reset the [AC] adapter by following these steps:
 
Unplug the Wii AC adapter at both ends (from the back of the Wii system and from the wall outlet or power strip).
The AC adapter must remain unplugged at both ends for a full 2 minutes.
It's also recommended you unplug anything connected to the USB ports and the Nintendo GameCube Controller ports (such as LAN Adapters, keyboards, Nintendo GameCube controllers, etc.).
While you're waiting, check the AC Adapter for the following:
1:Make sure that the word "Wii" and the model number "RVL-002 (USA)" molded into the AC adapter. Unlicensed products are not fully compatible and may not work correctly.
2:Check the AC Adapter for physical damage. Physical damage, such as frayed wiring or a cracked housing can cause the system to shut down. If your AC Adapter shows signs of physical damage and needs to be replaced, you can purchase one from Nintendo's online store.
After you've waited 2 minutes, plug the AC adapter into the Wii system and directly into a wall outlet, not a surge protector or power strip. If the power light comes on and stays on, then it appears resetting the AC Adapter worked.
If resetting the AC Adapter did not fix your power problems, please continue reading:
3:Avoid the use of unlicensed products such as memory cards, controllers, and cheat devices. Some of these products are poorly manufactured and may result in damage to your system. If one of these products is attached to your system, remove it and try resetting the AC Adapter again (see above)
4:Check any accessories that connect to the Nintendo GameCube Controller ports or the USB ports of the Wii -- whether licensed or not -- for physical damage. Physical damage, such as frayed wiring or a cracked housing can cause the system to shut down. Remove any damaged products and try resetting the AC Adapter again (see above).
5:Make sure the Wii has good ventilation. Avoid operating the Wii while it's on carpeting or inside an enclosed space. If you have the Wii placed in a vertical position , make sure the vent on the bottom is lined up properly with the hole in the plastic stand and no foreign material is obstructing that hole.
6:Check the vents on the back and side of the Wii for dust build up. The system will shut down if it cannot vent properly to prevent overheating. If there is a build-up, remove it using a vacuum cleaner with a soft brush attachment.
7:Make sure that your wall outlet works. To check it, try plugging a lamp into the same outlet where your system was plugged in. Turn the lamp on to verify the outlet works. Also, make sure you are not using an outlet that is operated from a wall switch. If you do, make sure the wall switch is in the ON position.
8:Make sure the AC adapter is attached properly. Firmly plug your AC adapter into the back of the Wii (the port is labeled 12V IN) and into a working wall outlet (not a power strip or surge protector).
9:Once plugged in, check the power light on the Power button to see if the system is receiving power
good luck .

Can not start my computer


Plug the unit directly to the ac outlet if it is plug into a surge protector. See if it boots. Did you shut it down yesterday or was it left running? Any bad weather last night? You could try another computer memory and see it is the memory. Not sure what it could be at this point. What type of system is it?
It could possibly be a bad power supply.

I hope this helps.

Computer shut down


The sparking has probably caused your circuit protection inside the AC adapter to turn off the current.
Also, when you are plugging an adapter in,,do not have it plugged into the wall power outlet when plugging into the laptop,,,plug into the laptop first and then plug into the wall.
