Won't build top pressure an shut off

Wont build top pressure an blow off replaced start up switch cause was broken an also replaced psi valve to see if that was bad? Won't blow off cause cant reach top pressure an keeps running till belts seizes up at slower speed. This compressor has No time on it an is New even though it's a 2010 compressor less then 1 hours on this compressor.

It sounds like your pressure switch is not set correctly. It is possible it is set too high for the compressor you have.

SOURCE: air leaks from pressure switch after compressor

if its leaking steady from the unloading valve on the pressure switch after the compressor stops you have a bad check valve!replace it and youl be fine,dont forget to depressurize your tank before!!!!! and use teflon tape on the treads to avoid air leaks when you replace it!

My ingersoll rand compressor won't get up to set pressure


Hi bryon


Here are a few things to check, you may have already checked some of these.


Electricity...Compressors will run best with full 115Vot 15AMP/Or 220V electrical supply from a circuit, over the shortest electrical cord as possible.


Air Leaks..Place your ear close to the compressor and listen for air leaking, if you hear air that is not normal and means you have to locate and repair whatever it is that is leaking.
Check the air unloader valve... The air unloader valve will blown out air when you turned off the compressor, that is normal.
But it should not have air leaking out of it all of the time. If so then it is faulty and in need of repair/replacement.


Valves...If either the intake or exaust valves fail, breaks, or fails to seat, then your compressor will run 24 hours a day and never build up to the correct pressure for shut-off.


Gaskets...Check to see if your gaskets have failed.
You could have a gasket failure between the pistons and you will never know it because it shows no external air leak.
If this situation happens then the air will only cycle between cylinders and never build up the correct air pressure.
One way to check the gasket is remove the air filter, then put your hand over the intake.
Please take time to rate me

If correct then it will suck you hand against the intake.
If the valve or valves have failed then you will feel the air sucking in and blowing out.


Piston Rings and Cylinder...The piston rings could be stuck,broken, or worn and not allowing the correct pressure to build up in your tank.
A worn cylinder will also contribute to the problem of pressure build-up.



Pressure Switch...Check for air leaks at the pressure switch, it has a rubber diaphram that can fail and leak air out of the system.

Air compressor not unloading


Check the pressure switch. The unloader valve is actually in the pressure switch where the small air line from the tank check valve attaches to it. When the pressure switch turns the motor off it then lets the head pressure bleed off so the motor can restart the next time pressure drops in the tank. If it's not working and bleeding off the head pressure the cold start valve (the one with the pin in it) also won't open so the motor can restart and warn up properly.

Craftsman air compressor model 191.135131 wont build pressure


I can not find a Craftsman compressor with that model number anywhere so here are a couple things to look into. If the compressor fills to 70psi and keeps on running check the valve plate and piston/cylinder assemblies. Check that the valve reeds on the valve plate are not bent, broken or warped from heat. Then check that the wiper (oil less) or pistion rings (oil splash) are not damaged and that the cylinder wall is not scarred up. Any of these will let the compressor fill up to the point where the air pressure leaks past the valves or piston and won't fill any further. If the compressor fills to 70psi then shuts off the problem is in the pressure switch. Some have an adjustment screw or bolt to control when it turns on and shuts off. If you had a drop from 100 to 70 the springs may be weak or broke and you'll have to replace the switch.

Hi
your pressure switch is bad. so it isnt cutting off the compressor. the part number is N003306SV and can be obtained from Dewalt on Servicenet.

Starts then dies & won't restart


check fuel pressure, should be 40 psi.
try 2 things

spray starting fluid in air intake to see if it will stay running. It's fue then.

Try turning key to on nd wait 5 seconds for system to build pressure and pump to shut off. Turn key off, wait for relay clcik noise or 10 seconds. then turn key to ON again and wait 5 seconds to build pressure again. Then start engine. If it starts better, you have a bad check valve in the fuel pump or a bad pressure regulator on the fuel rail (unlikely).

My washer wont fill with water what seems to be the problem


Hi

If the washer won't fill you'll need to check for the water inlet hose, the water inlet valve and the pressure/water level switch assembly. Inspect the inlet hose coming to the washer for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the pressure/water level switch assembly should be replaced. Hope this helps... Please post back if you need more information.

I have a Clarke 150 ltr compressor and the original pressure switch broke so I replaced it with another one. When I start it, it builds pressure fine upto 150 psi (is this right) and then cuts out. Then...


no, Its sounds like you have a receiver tank check valve bad. This valve is designed to hold pressure in the tank . there should be a line on the side of the check valve that goes to the pressure switch. This allows air trapped from the top of the check valve to the compressor to escape so when the compressor starts it does not have to start against pressure in the system. Loosen the line at the check valve or the pressure switch. if it blows until the unit starts or drains the receiver tank if not powered up replace the receiver tank check valve.

My jet pump has a 20 - 40 pressure switch but won't give any more than 30 psi. Whats wrong?


There are several causes for this to occur.
1. If it is a 20-40 switch right out of the box it may not be set correctly. I have had this happen. If it builds to 30psi and shuts right off without straining to build to 40psi adjust the Cut-Out pressure up to 40psi. There are two different adjustments on a well switch. One for Cut In / Cut Out psi and one for Cut Out psi.
2. Lack of head pressure being built by the pump can be the cause. This can be attributed to the wrong Jetting in the pump. IE: A shallow well jet/venturi on a deep well.
3. The pump may have a bad impeller, but the pump will generally really strain to build pressure and a bad impeller will be loud, like grinding at times.
4. Double check the pre-set pressure in bladder tank also.

I can't shut off the air coming out the valve on the bottom of the compressor. Is there something that blew out?


Sounds like a saftey valve has gone bad?????? These valves are used to prevent excessive pressure from building up in the tank. They are usually spring loaded by the manufacturer to a specific pressure. Sometimes however.... condensation builds up inside the tank due to the changing ambient temp. Compressors get REAL hot when they build up air pressure...... the higher the psi.... the higher/hotter they get! When a compressor reaches the its proper shut off point it stops, as it cools condinsation has a tendency to form inside the tank...... eventually dripping down into the bottom of the tank, forming a puddle...... which then sits there..... sometimes for a LONG time! This water/puddle is unfortunatelly right where the safty valve is mounted............. in THE BOTTOM OF THE COMPRESSOR! (exactlly where you indicated its leaking air?) in the bottom........???? The saftey valve has probably corroded due to moister inside the tank. Unfortunatelly this is a VERY IMPORTANT SAFTY DEVICE...... & SHOULD BE REPLACED WITH THE PROPER MANUFACTER RECOMMENDED PSI VALUE WHEN IT BEGINS TO HAVE ISSUES. Sometimes...... when lucky...... it can be removed, cleaned, & lubricated..... caution should be observed however..... should any pitting of the metal caused by excessive corrosion be observed during or after cleaning........ it should IMMEDIATELLY be replaced!!!!!!!!!! REMEMBER, THIS DEVICE IS THERE FOR SAFTEY REASONS!!!! DO NOT REMOVE IT FROM THE BOTTOM OF COMPRESSOR AND INSTALL A PLUG INSTEAD..... DOING THIS COULD CAUSE EXCESSIVE PRESSURE TO BUILD UP TO A POINT OF EXPLOSION!!!!!!!!!!!!!!!!!!! ONLY REPLACE VALVE WITH IDENTICAL PSI VALUE!!!!!!!!!!!!!!!!!!! Hope this helps & GOOD LUCK!
