What to do if my Doosan P185WJD Air Compressor won’t start/run?
- TTroy BirdAug 4, 2025
If your Doosan Air Compressor won’t start or run, start by adding clean diesel fuel if you are out of fuel. If the fuel filters are clogged, service them. If the compressor oil level is too low, add the correct oil. Check for loose wire connections and repair or replace them. Also, check the battery voltage and electrolyte level, ensuring good connections. If the voltage at the shutdown solenoid is less than 10 volts, charge the battery and alternator, making necessary repairs. Other potential issues include a defective alternator (replace or repair), a malfunctioning start switch, or a defective D2 diode, each requiring replacement. Finally, check for blown fuses and replace them, looking for any shorts.
