I need to replace a buzzing "connector switch" in my air unit

It is the automatic switch that makes the second 120 line engage when triggered by the thermostat. It is in the out side unit. An electromagnet pulls down the contact to complete the curcuit when required but the magnet does not seem strong enough so it buzzes and did not used to.
What is it called and where can I buy one?

It is called a contactor and you can buy one at however the buzzing is often more related electrical frequency rather then if it is weak or not...
Replaceing this is a good idea though because the contacts wear out and can weld together if they get too hot...

The one you would want is on page 272 in want a 1 pole 24 volt coil...probably 1V598

1995 chevy silverado c1500 air conditioning unit blowing hot air - what to do

There are 2 pressure switches on the refrigerant lines. Pull off a connector and short the wires on the connector. If the clutch engages then the pressure switch is bad.

Air conditioner not working on 1993 bonnevile, compressor not engaging, charge good, power at low pressure switch, switch is closed, need to know what turns a/c relay for compressor clutch on, clutch...

the ECM supplies the ground circuit for the a/c clutch. the high pressure switch also needs to be closed to engage the clutch. when the low pressure switch and the high pressure switch are closed that completes the power circuit to trigger the relay.then the power on the #30 terminal can connect to the #87 terminal to send power to the a/c clutch.

My control unit wont switch on ac

It may not be a control unit issue. Be sure to check all fuses. You may have a pressure switch issue. There are at least 2 pressure switches located in the engine compartment. One is usually located on the back of the ac pump and there is usually one on the passenger side near the firewall on one of the aluminum ac lines. You can simply unplug the one by the firewall and take a paper clip and unfold it and use it for a jumper on the connector. Put one end of the clip in one side of the connector (the end of the connector that plugs into the switch) and the other end of the clip into the other side of the connector. Start your Tahoe and turn the ac on and if the ac pump is turning with the ac clutch engaged that means that you either have a bad switch or your are low on refrigerant. Feel the aluminum ac lines and see if they are getting cold. If so I would suspect a bad pressure switch. You can remove the paper clip while the vehicle is running and put it back in if you are not sure if the ac clutch is engaged. It should make a clicking noise when it engages and disengages. It is very simple to replace that switch. Simply unscrew it and screw the new one in and plug it in. It will hiss just a little when you remove and install so be quick. It will stop when you remove the old one and will hiss again a little when installing the new one. The switch on the back of the pump is not so easy. The refrigerant needs to be evacuated from the system before it can be replaced.

My Makita AT1150A stapler does not shoot any staples. Air comes out around the trigger when pressed but does not do anything else. What do I do to fix this problem?

Check to see if there is any foreign object jamming the striker bar. These units also have a diaphragm that sometimes needs to be replaced. If you do not have an automatic oiler on the line the diaphragm could have cracked allowing air to pass through. The Stapler can not build up the necessary pressure to fire the striker driving in the stapler. Damaged or cracked this will need to be replaced. Not difficult and easy to DIY job. Do NOT hook up to air when doing this service. Dirt and grim can also jam the unit. Clean lightly oil, work the unit and see if it frees up. I typically put a few drops of oil made for pneumatic tools directly into the unit. Each time I pull the pneumatic tools out to use. I do not have an inline oiler. :)
Typically at the Male nipple connection where the brass female connector hooks too. 2-3 drops only!
Hope this helps!

I need help replacing a bostitch framing air nailer trigger model 28ww it's leaking air and won't work.

follow closely, do you have a new trigger assembly because the problem is with one o ring commonly referred as the purple o ring in the kits? either way the procedure to remove the trigger is first knock out the roll pin for the trigger latch and then the 2 roll pins for the trigger assembly. next get a shop rag or equivelant and place under the now exposed trigger assembly and then while holding the collar on the air chuck plug into tool and hold rag tight and trigger will "pop" out pull the chuck away and remove the 2 pins to disassemble the assembly or install in reverse order lubricating the o rings first. Let me know if you have any questions or problems.

No air pressure at the hose

It sounds like you have trouble with your pressure regulator. Make sure that the knob for the regulator is turned clockwise to increase pressure. If this doesn't work, you may need to replace the regulator.
