The unit could have trash in the valve not allowing it to seat. Relief air and clean. If the unit blows air out for a couple of seconds after the unit shuts down that is normal. That is how the pneumatic valve works.

Husky air compressor

Your compressor shouldn't run more than ten to fifteen minutes before shutting off. The pressure should be posted on the machine somewhere ( a decal usually says xxxpsi). You evidently have an air leak somewhere. On the bottom of the air tank there is a valve for draining the tank of air and any moisture. Make sure to close that valve by hand only (Screw it in all the way by hand and remember, you are working upside down, so don't get confused as to which way to turn it). If the valve will not unscrew to drain the tank, you can use a pliers to loosen the valve to let the air out, but be sure you are turning it in the correct direction or you'll break the drain valve!! Now that you have the drain valve closed, turn the compressor on and watch the pressure gauge. When the pressure gauge reads the pressure on the decal, the machine should turn off. If the pressure gauge stops climbing before it reaches the specified pressure, you have an air leak somewhere. You can either feel for the leak at the air line connectors by hand or mix a dish soap and water solution the pour on the air line connectors to look for the leak. Keep the soap solution away from the motor!! When you find the leak, drain the tank using the drain valve at the bottom of the tank, disconnect the hose coupling that is leaking and wrap Teflon tape around the threaded portion of the male end of the fitting (3 wraps should do it) and reconnect the coupling ( tighten it well). Close the drain valve and start the compressor again. and check all fittings for leaks again.

Yamaha 1978 750 Special Fuel Leaking Problem

These type of fuel shut offs do not have a manual off position. They are automatically operated by engine vaccuum when working properly. They have malfunctioned and allowed fuel to overflow into the airfilter box(the black box) untill repair time use a long piece of hose to connect the large outlet of each shutoff to eachother or plug the end of two short pieces. The carbs have a drain screw on the very bottom of each facing left , right or straight down. you could also drain the carbs however once the fuel supply is cut to them they should not leak any further. Leave the carb fuel hoses from the tank disconnected. You should drain the tank by siphon and the residual gas that is already in the air box can be drained from the hose on the bottom of the box. This is a mess but once you get all this drained it should stop leaking

I have a 2 gallon compressor , no air comes out?

Check if air intake is clogged.
Check if drain valve on tank bottom is open or closed.
Look at pressure gauge and see if pressure is zero.
Adjust pressure so tank will hold 80-120 psi.
Check air lines between compressor and tank to see if they are leaking. Listen for leaking air while motor is running.

Turn on frecuntly

If it is restarting that frequently you have an air leak somewhere. First check the drain valve on the bottom of the tank. If that's closed do the following to find the leak: You should remove the cover on the manifold where the guages are and get a spray bottle with soapy water in it. Let the compressor run until it shuts off then unplug it so it won't keep restarting while your working. Spray the soapy water on things like the copper line from the pump to the tank, the pressure regulator, guages and around the tank drain valve. You are looking for bubbling from an air leak. Make sure it's from a leak and not just boiling the solution off as parts of the compressor will get quite hot while it's filling the tank. Whatever is leaking has to be tightened or replaced.

My mastercraft aircompressor kit runs good but does not hold air

Check for leak through any of the sources in the tank , if so there will be no collection, you must observe for air noise hiss to identify the place of leak.Plug all the leaks and try, check on drain taps, pressure cut off switches or any leak on the tank.

We've had two of thee units for a couple weeks now. Then suddenly they started leaking a LOT of water. How do we fix this problem asap?!

If you haven't been draining the water collection tanks regularly, that could be the problem. With that said, the units should shut down automatically, when the tanks are full. If they are not doing that, the water tank full sensors are faulty. The drain plug is on the rear of the unit, just above floor level. To drain it, place a low sided pan or bowl capable of holding 1 quart water, under the drain plug. Unscrew the plug and allow it to drain in the pan. Or disconnect the unit and roll it to a floor drain or outdoors and drain it/them.

In addition, check the exhaust hose(s) for obstruction r drooping to much. Either will trap moisture that should be exhausting out the window.

Hope this helped you to troubleshoot and solve the problem. Thanks for choosing FixYa.

Hotpoint MAC-130 air conditioner dripping water

You need to blow out the drain line where it hooks up to the pan and clean out the drip pan. It doesn't matter how clean you keep the filter, that's just to keep the evaporator coils clean, which is important in itself. But algae will grow in the drip pan if it is not tilted to drain correctly and will clog up the drain line. If you put a level on the top of the unit, the bubble should JUST BARELY break the line on the OPPOSITE side from the drain outlet on the pan. Hope this helps.
