Question and Answers

Q:

After being stored 15 months do i need to do anything to start it up 919152930 Craftsman Air compressor

A:

Thanks for the inquiry about your air compressor model 919152930, I will be glad to assist you. After a long storage there are a few things you should do before starting up the unit.  First you should drain the tank, there could still be some condensation left for before.  Next inspect all the wiring for condition, breaks, worn insulation on wires and any abnormal wear around terminals and controls including the service cord.    Check the fan blade for any debris that may have collected on and around the fan and housing. Also be sure it is tightly connected to the shaft.  When you start it up listen for any unusual sounds and prepare to disconnect quickly if needed. I hope this helps you. If you should need any service here is a link to Sears Home Services and for parts here is a link to Sears Parts Direct. Ron H.

Q:

6 HP 33 gal Air compressor won't shut off at 120 psi

A:

I can understand your concern and I appreciate the efforts you've made to remedy this problem of your air compressor not shutting off. It's disappointing when parts you need are no longer manufactured. I'm wondering if it could it be a wiring issue with the pressure switch. I've located a link that follows this line of thought in thinking that there may be two contacts within the switch that might be stuck together. Click on the link below to view the page. Though this link discusses a different model number, the mechanics are likely going to be very similar. Keep in mind that an expert will be responding within the next two business days if not sooner and will likely offer you more information and instruction. I hope this information will be helpful and have a nice day.

Thank you for your question.

 

I am sorry you are having a problem with the Craftsman air compressor 919.152930. If the motor will not turn off when it should there is a problem with the pressure switch. I checked and we no longer offer a replacement switch for that model. I recommend checking on line. The best way to find a universal switch is to type "air compressor pressure switch control valve 95-125 psi" in Google. This should pull up many different pressure switches. Just look for the switch closest to yours. You many need to move the small tube from one side to the other to get the switch to fit. Other than that, the switch should be close to a direct replacement.

 

I hope this is helpful. If you need further assistance, please reply below with more details.

 

Thank you for using Mange my life.

Thank you for using ManageMyLife.com. I'm sorry to hear of the issue you are experiencing with the compressor not building pressure past 60-70 psi, I know how frustrating that can be.

Assuming the compressor doesn't have any leaks eminating from the lower manifold or the outlet tube, I would recommend pulling head and visually inspect the valve plate for any damaged reed valves. If a reed valve broke off, it can cause damage to the top of the connecting rod and/or cylinder sleeve, which would explain why only 1 cylinder is working properly. I have attached step-by-step instructions below to help guide you through the diagnosis of the valve:

  1. Disconnect electrical power to the compressor and bleed off all air pressure before proceeding with repair.
  2. Remove compressor shroud.
  3. Remove the Head & Valve Plate.
  4. Verify that the Exhaust Valve has broken.
  5. Inspect the Connecting Rod & Cylinder Sleeve for damage.
  6. If the Rod & Sleeve are damaged, replace as necessary.
  7. Place a new Valve Plate assembly on the unit and re-install the Head & Seal.
  8. Tighten the 4 Head bolts to 7-10 Ft./Lbs.
  9. Reinstall compressor shroud.
  10. Start the compressor and allow to run up to pressure.

I would suspect that we have a damaged Valve Plate and/or Connecting Rod/Cylinder. This verification will let you know what will need to be replaced to get the compressor operational again.

If you would feel more confident have a Sears Home Service technician help assist with the diagnosis/repair, click here to be directed to the page to set up service.
