If the Craftsman air compressor motor won't start, first ensure the power cord is properly plugged in and the switch is turned on. Check your circuit box for the correct fuse size. If the fuse has tripped, reset it and attempt to restart the unit. If the fuse repeatedly trips, it may be necessary to replace the check valve or contact a service technician.
Why is my Craftsman 921.153120 Air Compressor safety valve leaking air?
If you notice air leaking from the safety valve of your Craftsman air compressor, try manually operating the safety valve by pulling its ring. If the valve continues to leak while in the closed position, it needs to be replaced.
What to do if my Craftsman 921.153120 Air Compressor has excessive tank pressure?
If your Craftsman air compressor shows excessive tank pressure, immediately move the Auto-On/Off lever to the Off position. If the unit fails to shut off, unplug it from the power source and then contact a service technician.
How to fix air leaks at the check valve of a Craftsman 921.153120 Air Compressor?
If your Craftsman air compressor has air leaks at the check valve or pressure relief valve, it could be due to a defective check valve causing a constant air leak at the pressure relief valve when the compressor is off but the tank is pressurized. To fix this, drain the tank, then remove and either clean or replace the check valve.
Why is my Craftsman Air Compressor leaking air between head and cylinder?
If your Craftsman air compressor has air leaks between the head and cylinder, ensure that the head bolts are properly torqued. If the leak persists, it is recommended to contact a service technician.
How to reduce moisture in Craftsman 921.153120 discharge?
To address excessive moisture in the discharge air of your Craftsman air compressor, drain the tank after each use to remove accumulated water. Remember that high humidity can increase condensation. Consider using water filters on your air line. Note that water condensation is not a sign of compressor malfunction. Ensure the compressor's air output exceeds your tool's air consumption rate.
What to do if Craftsman 921.153120 Air Compressor pressure drops when using an accessory?
If the pressure reading on the regulated pressure gauge of your Craftsman air compressor drops when an accessory is being used, and the pressure drop is excessive, replace the regulator. Remember to adjust the regulated pressure while the accessory is in use. A minimal pressure loss during initial tool use is normal.
What to do if my Craftsman 921.153120 Air Compressor is leaking from the tank welds?
Never attempt to repair air leaks from the tank body or tank welds on your Craftsman air compressor by drilling, welding, or modifying the tank. This will weaken the tank and create a risk of rupture or explosion. The compressor cannot be repaired; discontinue its use immediately.
