Guide :Air Tools & Compressors : Air Tools & Compressors
Compressor is building up pressure very slow.
I have a 2 year old craftsman air compressor, model 919.167782
The compressor is not pumping up fast. It ran 1 hour and only pumped up to 30 lbs (and I wasn't using any air)
- I replaced the entire pressure switch assemply and regulator.
- I disconnected the tube from the compressor head to the check valve to see if air was being discharged from the head and it is.
- It is an oilless compressor. The two pistons are working properly.
- Normally the tube from the compressor head to the check valve gets hot very quickly. The tube on this compressor is only getting warm, even after 1 hour
