Why is the discharge gas temperature high in my GE H302 Air Compressor?
- S
  Shannon MitchellAug 9, 2025
  High discharge gas temperature in your GE Air Compressor can stem from several causes. It could be due to excessive compression ratio because of leaking suction valves or piston rings. Other potential causes include high cylinder suction gas temperature, reduced cylinder suction pressure, leaking discharge valves or piston rings, fouled intercooler piping, improper lube oil, or a change in cylinder mode of operation. To resolve this, inspect and repair any leaking suction valves or piston rings, reduce the cylinder suction gas temperature, remove any restrictions affecting cylinder suction pressure, replace leaking discharge valves or piston rings, clean the intercooler piping, select appropriate lube oil and adjust the rate, and adjust the operation mode as required.

What to do if there is excessive packing leakage in my GE Air Compressor?

  Jason BallAug 15, 2025
  If your GE Air Compressor has excessive packing leakage, it could be due to several reasons: worn packing rings, loose packing case bolts, incorrectly assembled/installed packing rings, improper lube oil selection, contaminants affecting packing rings, the packing not being properly seated, new packing installed on a worn rod or damaged packing case, improper packing ring clearance, or oil dilution from liquid carryover. You should replace worn packing rings, tighten packing case bolts, reassemble or reinstall packing rings correctly, select appropriate lube oil and adjust the lube rate, remove contaminants, ensure packing is properly seated, replace the worn rod or damaged packing case, adjust packing ring clearance and rectify liquid carryover issues.

Why is there low oil supply pressure in my GE Air Compressor?
- P
  problesAug 27, 2025
  A low oil supply pressure in your GE Air Compressor can arise from several causes. These include a low oil level, oil pump failure, oil pulsations from excessively cold oil, an improperly adjusted oil pressure regulating valve, a dirty or collapsed oil filter element, a defective pressure gauge, oil foaming due to a high oil level, internal running gear leakage, or mechanical defects in the compressor frame. To resolve this, fill the oil to the correct level, repair or replace the oil pump, allow the oil to warm up to operating temperature, adjust the oil pressure regulating valve, replace the oil filter element, replace the defective pressure gauge, reduce the oil level, inspect and repair internal running gear, and inspect and repair any mechanical defects.

What to do if my GE Air Compressor compressor will not rotate?

  Brian BrownSep 2, 2025
  If the compressor on your GE Air Compressor will not rotate, it could be due to cylinders gas pressure load, improper piston end clearance, foreign material in the cylinder, or a mechanical seizure in the running gear. To resolve this, remove excess gas pressure from cylinders, adjust piston end clearance, remove any foreign materials from the cylinder, and inspect and repair mechanical components.

How to fix cylinder noise or knock in GE Air Compressor?
- W
  William GonzalezNov 20, 2025
  If your GE Air Compressor exhibits cylinder noise or knock, several factors could be responsible. These include a piston loose on the rod, improper piston end clearance, a loose crosshead balance weight, a damaged crosshead or excessive clearance, loose crosshead pin or pin caps, a loose packing case or false head, broken or leaking valves, worn or damaged piston rings, a valve improperly seated or a damaged seat gasket, a loose VVCP Jam Nut, or a loose or broken VVCP piston. To address this, tighten the piston on the rod, adjust the piston end clearance, tighten the crosshead balance weight, replace or repair the crosshead, tighten the crosshead pin or pin caps, tighten the packing case or false head, replace or repair broken or leaking valves, replace worn or damaged piston rings, reseat...
