Question about Clarke Air Tools & Compressors

Open Question

Clarke SE45C270 We have had to re-wire the star/delta starter control unit and need to know when the solenoid valve on the delivery pipe should switch. Presumably on start up it should vent when it is running in star and close when in delta??? Is the valve normally open or normally closed?

SOURCE: starter valve dont close hatachi ec119sa (air compressor)

The start valve gives your motor a running start before the motor begins to load as the pressure increases from an empty tank. The motor strain is more profound when there is pressure in the tank. If you plug the valve, the motor will instantly encounter a heavy load because it has to force air into a partially filled tank. This extra load without the valve will shorten the life of the capacitors and motor windings. There could be two problems with your unit that can revealed by test. What actually closes the valve is a certain volume of air produced by the compressor. If the compressor is not pumping to full efficiency or there are leaks in the discharge hose the valve will not close. Or the valve is faulty. With an empty tank, plug the valve and run compressor and test airline for leaks with soapy water. If no leaks, empty tank of air and restart compressor and take note of the amount of time it takes to fill the tanks to shut off. If it takes an unusually long time to fill, then the compressor probably has valve problems causing low air volume. If the compressor fills to shut off in a short time frame as compared to a similar model then replace the valve. Leaking valves in the head will also cause the pump and discharge tube to run very hot. Parts are available at Good luck with your repair.

SOURCE: APC Solenoid Valve Knocking

The APC valve regulates boost pressure (via the wastegate) to avoid over-pressurising the engine. It ensures that a safe boost pressure isn't exceeded. Don't run with it disconnected or you risk blowing the engine!

Problem areas can include: knock sensor on the engine block (also poor quality fuel, dirty engine causing knock); engine ECU.

You need to provide more information about when this happens:

hard accelerating? (likely poor quality fuel, dirty plugs/engine causing knock) and general driving similar.

idling? possibly a knock sensor or ECU related problem

What rpm? what boost gauge pressure?

as an outside chance, maybe a sticky wastegate

SOURCE: VW Polo 2001 - Electric Windows wont open from Drivers side..

I removed all 3 switches from driver and passenger door, which is really easy with a flat head screw driver. took them completely apart, very carefully, with a small screwdriver out of a christmas cracker. put them back together again and 2 switches started working, so I put 1 in the drivers side and 1 in the passengers side so now my drivers door window opens and I lean over to open the passenger door. cool, no money spent...yet ;o)

SOURCE: how do i connect he differenial pressure switch

Your question is a bit unclear, but I assume you are asking how to wire the pressure switch in a piston compressor.

See the diagram, below.

You should have a wire from the L1 (first incoming main voltage) terminal to the pressure switch, and from the other pressure switch terminal back to the starter coil. You will also have a wire from L2 (second main voltage terminal) to the overload, and from the other overload terminal to the other side of the coil. In this arrangement, the motor starter coil must be rated at the SAME VOLTAGE as your incoming power.

This diagram works the same for single phase machines (they just don't have the third wire coming from the supply through the starter and overload to the motor.

If your machine has other safety controls (like a low oil switch), It can be wired in series with either the pressure switch or the overload.

When doing a load and selecting Cold/Cold temps, I am only getting HOT water. All the temp settings are only allowing HOT water to flow. I have a Whirlpool GHW9150PW0 model. Anyone know why this is?

The cold part of the water inlet/mixing valve assembly (part #8181694) is not working. Disconnect power to the machine then remove the three screws at the back of the top panel securing it to the cabinet. Once the screws are removed, slide the top panel to the back of the machine then lift it off.

Check the valve solenoids using an ohmmeter. Disconnect a wire from each of the solenoids then measure the resistance between the terminals of each solenoid with the ohmmeter set to X100. The resistance of the solenoids must be almost identical at about 800 ohms.

Check the continuity of the solenoid wiring harness to the central control unit. Make sure the connector at the central control unit is properly seated to ensure good connection. The 4-wire valve solenoid connector is the fourth connector from the left (facing the front of the washer) of the central control unit.

Disconnect the solenoid wires from its terminals if the resistances of the solenoids found above are the same and there's a good connection between the solenoids and the central control unit. Cleaning the terminals will help. Reconnect the solenoid wires in place of the other solenoid wires, and then start a new cycle to check if the temperature of the water coming into the washer changes.

Replace the water inlet/mixing valve if one of the following is observed:
  1. The resistances of the valve solenoids are not the same; one solenoid is open, and the connection between the solenoids and the central control unit is okay.
  2. The water temperature does not change after the hot and cold solenoid wires are interchanged.
Remove the fill hoses then remove the valve assembly mounting screws. Disconnect the valve assembly outlet hose then remove the valve assembly from the cabinet. Connect the outlet hose to the new valve assembly then mount it into position in the cabinet with the mounting screws.

Slide the top panel into position then secure it the three screws to the back of the machine.

Please let us know how this guide helped you or not so that we may know how it worked and how to improve it, if necessary.

I want to use one condener unit to cool a freezer and a cooler at two different temperatures, how do I do that? with a head master?

You need to split the delivery and return tubing, then install a solenoid in each delivery tube. The solenoid valve will be controlled or powered by a thermostat in each compartment. You then install a low pressure switch on the suction or return side near the compressor. This will switch the compressor off when both solenoid valves are closed. Hope this makes sense.
