What happens if there is no orifice tube?

Faulty orifice tubes can also result in too little refrigerant flow through the evaporator. If this is the case, the flow of refrigerant will not be enough to absorb the heat that is coming from the condenser. When this occurs, the A/C simply will not be performing well enough to allow the system to cool.

How do you know if your AC expansion valve is bad?

The most recognizable symptom of a bad A/C expansion valve is when you turn on your air conditioner and warm air starts blowing out of the vents. This would obviously mean that not enough refrigerant is making its way to the core of the evaporator.

Are all orifice tubes the same size?

it all depends on the car, type, model, original O tube size, factory refrigerant or retrofit..

What causes an orifice tube to fail in an AC system?

Most orifice tubes fail due to contamination in the AC system due to sealer, oil degradation or mechanical deterioration. Replacing a plugged orifice tube without solving the root problem will result in another plugged orifice tube.

Do you need to replace orifice tube, now problem?

Your compressor is going. You not only need to replace the orifice tube, but the compressor, condenser, accumulator and flush all the lines. If you don’t, the problem will just return and if you only replace the compressor, the shavings will make their way back to the new compressor and take it out.

Where is the orifice tube located in an auto?

The orifice tube may be located: In the inlet tube to the evaporator. Built into the high pressure liquid line. Inserted into the high pressure line near the condenser. The 5 different types of Auto AC orifice and expansion valves.

How do you remove the orifice tube in an evaporator?

Remove the orifice tube using needle nose pliers or removal tool. Note the orientation of the orifice tube. It must go back in the same way. Lubricate the O-rings on the new orifice tube with AC oil. Insert the new orifice tube into the evaporator or LLOT or SLOT.

Where is the orifice tube located in an air conditioning system?

If your system uses an orifice tube instead of an expansion valve, most of the procedures are nearly the same, the difference is that the orifice tube is located Inside the line going to the evaporator. Step 1: Locate the orifice tube.

Why is my orifice tube not working properly?

If either the evaporator or the refrigerant hose coming from the evaporator are warm or hot to the touch, this could indicate that the orifice tube isn’t doing its job. However, there could be many other causes for this problem, as well.

Where is the orifice tube located in Ricks free auto?

Lubricate the O-rings on the new orifice tube with AC oil. Insert the new orifice tube into the evaporator or LLOT or SLOT. Reconnect the liquid line to the evaporator or condenser and follow factory specs for tightening (if required).
