Why Champion r-15 Air Compressor motor will not start?
- M
  mariarodriguezAug 19, 2025
  The Champion Air Compressor motor might fail to start due to several reasons. It could be due to open main switch and fuses, which requires checking all fuses and switches, and inspecting for loose or faulty wires. Another cause may be open starter magnetic coils, suggesting a check of the overload relay in the starter and resetting it. A tripped thermal overload also prevents starting, so reset the starter. If it repeatedly trips, have the electrical system inspected by an electrician. A defective pressure switch with contacts that won't close or low voltage could also be the cause; repair or replace the pressure switch, and check the voltage with a voltmeter to ensure it matches the unit's specifications.

What to do if Champion r-15 Air Compressor starter trips repeatedly?
- A
  Amanda PhillipsAug 21, 2025
  If the starter on your Champion Air Compressor trips repeatedly, several factors could be responsible. Start by checking the pressure switch, as it may be improperly adjusted and need adjustment or replacement. A faulty check valve can also cause this issue, requiring cleaning or replacement. Ensure that the fuse size or magnetic starter coil is correctly rated. Low voltage could be a factor, so use a voltmeter to verify that the voltage matches the unit's specifications. In some cases, a defective motor may be the cause, necessitating replacement.

Why Champion r-15 Air Compressor runs hot?
- B
  Brenda SchultzAug 23, 2025
  If your Champion Air Compressor is running hot, several factors could be the cause. Ensure the flywheel rotation is correct (counter-clockwise when viewed from the drive side). Defective compressor valves can also lead to overheating, requiring installation of a new valve plate assembly. A dirty air filter restricts airflow, so clean or replace it. Lastly, a dirty cylinder or intercooler can impede heat dissipation, so clean the cylinder fins and/or intercooler.

What causes excessive oil consumption in Champion r-15 Air Compressor?
- L
  Laura McintyreAug 26, 2025
  Excessive oil consumption in your Champion Air Compressor can stem from several issues: * A dirty air filter * Wrong oil viscosity * Oil leaks * Worn piston rings * Scored cylinder Clean or replace the air filter. Refill with proper viscosity oil. Tighten bolts and replace gaskets to address oil leaks. Replace worn piston rings or a scored cylinder.

Why Champion r-15 tank pressure builds up slowly?
- B
  barajassandraAug 28, 2025
  Slow tank pressure buildup in your Champion Air Compressor can be attributed to a few common issues. Start by checking for air leaks and tighten any loose fittings. A dirty air filter can restrict airflow, so clean or replace it. Finally, defective compressor valves can impede pressure buildup, requiring the installation of new valves.

What causes Champion r-15 tank pressure to build up quickly?
- J
  Jordan HendersonSep 1, 2025
  If the tank pressure in your Champion Air Compressor builds up too quickly, it's likely due to excessive water in the tank. Drain the tank to resolve this issue.

What to do if Champion r-15 discharge pressure relief valve pops off while compressor is running?
- C
  Calvin WarrenSep 4, 2025
  If the discharge pressure relief valve on your Champion Air Compressor pops off while the compressor is running, it could be due to a wrong pressure switch setting or a defective ASME relief valve. Adjust to the correct setting or replace the valve.

What causes Champion r-15 not to unload (Units with head unloaders)?
- J
  Justin ChoiSep 6, 2025
  If your Champion Air Compressor fails to unload (for units with head unloaders), the issue might stem from a wrong pilot valve setting, a defective pilot valve, or a lack of air to the pilot valve. Try adjusting to the correct setting, replacing the pilot valve, or opening the ball valve to the pilot valve.

What causes Interstage pressure relief valve to pop off on Champion Air Compressor?
- Z
  Zachary WilliamsSep 8, 2025
  If the interstage pressure relief valve pops off on your Champion Air Compressor, it's likely due to defective compressor valves or improper valve installation. Install new valves or verify proper valve placement.
