What to do if Doosan C185WKU-T4I unit fails to shutdown?
- MMelissa CarterAug 26, 2025
If your Doosan Air Compressor unit fails to shutdown, it could be due to several reasons. A defective discharge air temperature switch, separator temperature switch, engine temperature switch, or engine oil pressure switch could be the cause; in any of these cases, replace the switch. Alternatively, a defective shutdown solenoid might be the issue; carefully block the air inlet to stop the engine. A malfunctioning relay can also cause this problem, so replace the relay. If the start switch is defective, pull the wire off the shutdown solenoid and replace the defective item. Lastly, a wire shorted hot can prevent shutdown; repair the short.
