Craftsman 919167280 air compressor Parts

Air compressor parts are not universally interchangeable. On a Craftsman air compressor model 919167280, we recommend replacing parts with the exact part number listed for your model because pressure-control and tank-related components are factory-matched for safe operating pressures (for example, the pressure switch, regulator, gauges, safety valve, and check valve). See the owner's manual for the correct parts list and safety guidance, and use Sears PartsDirect to search by model number when ordering.

What you can usually interchange (and what you should not)

Some fittings and accessories can match by thread size and pressure rating, but core compressor components should match the model-specific parts list.

• Sometimes interchangeable (verify specs): quick-connect couplers, some NPT nipples/bushings, air hoses, external pressure regulators (if properly rated)
• Not interchangeable (use model-listed parts): pressure switch, safety valve, tank pressure gauge, regulator, check valve, drain valve, pump valves
• Never substitute to change pressures: any part that could alter cut-in/cut-out or maximum tank pressure

Why exact-match parts matter on model 919167280

Your manual warns against adjustments or substitutions that alter factory-set operating pressures. Parts that control pressure and airflow are selected to work together so the unit cycles correctly and the tank stays within its designed limits.

High-impact parts called out in the parts list

Part type	What it does	Why interchange is risky
Pressure switch	Starts/stops the motor at set pressures	Wrong settings can cause improper cycling or unsafe pressure behavior
Safety valve	Opens to relieve excess pressure	Wrong rating can vent too early or too late
Check valve	Prevents backflow into the pump	Wrong style can cause hard starting or leaking
Regulator and gauges	Controls and displays outlet/tank pressure	Mismatch can cause inaccurate readings or poor control

How we recommend confirming compatibility

Use these checks before buying or installing any substitute part:

• Match the model number 919167280 on the parts list
• Match the part number and description in the model’s repair parts diagram
• Confirm thread type/size (for example, NPT) and orientation
• Confirm pressure rating meets or exceeds the compressor’s operating range
• After installation, test for leaks and verify normal cut-in/cut-out operation

Why it matters

Interchanging the wrong part can create air leaks, hard starting, inaccurate pressure control, or unsafe pressure behavior. Using the model-correct parts keeps performance consistent and supports safe operation.

The most common air compressor problems are air leaks, the compressor not building or holding tank pressure, and start or shutoff issues caused by the pressure switch, check valve, or fittings. For Craftsman model 919167280, these show up as leaking at fittings, leaking at the check valve, or the safety valve popping from excessive tank pressure (see the troubleshooting section in the owner's manual).

Common problems we see (and what they usually point to)

• Air leaks at fittings: loose tube fittings or worn seals
• Air leaks at or inside the check valve: damaged check valve seat or debris in the valve
• Safety valve pops open: pressure switch not shutting off at cut-out pressure, or cut-out set too high
• Not enough air for tools: air leaks, restricted intake filter, restricted check valve, or demand exceeds compressor capacity
• Pressure drops when using an accessory: some drop is normal; regulator may need adjustment under flow

Quick checks you can do safely

Always shut the unit off, unplug it, and bleed the tank and hose before working around pressurized parts.

• Listen for hissing around fittings, regulator, and pressure switch area
• Spray soapy water on suspected joints; bubbles confirm a leak
• Verify the compressor has 12 inches of clearance for ventilation and cooling
• Check that the outlet is properly grounded and matches the plug (no adapter)
• If the safety valve leaks, test it by pulling the ring; replace the valve if it still leaks

Symptom-to-cause cheat sheet

Symptom	Most common cause	What to do next
Safety valve pops	Pressure switch not shutting off	Turn OFF; troubleshoot pressure switch settings and operation
Leaks at fittings	Fittings not tight	Tighten fittings; recheck with soapy water
Leaks at check valve	Damaged/dirty check valve	Clean or replace check valve
Not enough air	Leaks or restricted intake	Find leaks; clean/replace intake filter

Why it matters

Air leaks and pressure-control problems waste air, overwork the pump, and can trigger unsafe overpressure conditions. The manual also warns not to modify or repair a leaking tank; a damaged tank must be replaced.

Yes, we can often fix a broken Craftsman air compressor model 919167280 by diagnosing the symptom (won’t start, won’t build pressure, leaks, or gauge issues) and then servicing common wear items like the air filter, check valve, regulator, or pressure switch. Use the owner's manual for model-specific safety and troubleshooting steps, and use Sears PartsDirect to find replacement parts by model number.

What “fixable” usually means

Most “broken” compressor complaints come down to a few serviceable problems:

• Won’t start: power supply, pressure switch, motor overload, or unloader/check valve issues
• Won’t build tank pressure: intake filter restriction, pump valve issues, or air leaks
• Air leaks: fittings, check valve, regulator, pressure switch release valve
• Pressure gauge or regulation problems: regulator adjustment or a failing gauge/regulator

Safe troubleshooting steps we recommend first

Before any inspection or repair, follow the manual’s safety guidance:

• Move the On/Auto/Off control to OFF
• Unplug the compressor (or disconnect electrical supply)
• Bleed the tank pressure completely
• Let the pump/head cool down before touching components
• Never operate with guards/covers removed

Quick symptom-to-likely-cause table

Symptom	Common cause	Typical next step
Safety valve pops	Pressure switch not cutting out	Stop use; test switch operation
Leaks at fittings	Loose fittings	Tighten; check with soapy water (do not overtighten)
Leaks at check valve	Damaged check valve seat	Clean or replace check valve
Drops under tool use	Normal some drop; regulator set low	Adjust regulator under flow

Why it matters

Compressed air, moving parts, and heat make “quick fixes” risky. Correct diagnosis prevents repeat failures, protects the tank and pump, and helps your compressor reach proper cut-in and cut-out operation without constant leaking or short cycling.

For a Craftsman 919167280 air compressor, repair is worth it when the problem is a common service item (pressure switch, check valve, fittings, or leaks) and the tank is sound. If the air tank is leaking at the tank or welds, replacement is the practical choice because the tank is the pressure vessel.

Quick decision checklist

• Repair it if it:
  • Won’t start but has power and a normal cord/plug
  • Leaks at fittings, the check valve, or the pressure switch release valve
  • Won’t build pressure due to a valve, gasket, or pump issue
  • Has a control problem (pressure switch not shutting off at cut-out)
• Replace it if it:
  • Leaks in the air tank or at tank welds
  • Has severe corrosion, dents, or damage on the tank
  • Has repeated safety valve popping caused by unsafe overpressure conditions

Typical repair costs vs. value (what we see most often)

Issue type	Common symptoms	Typical fix	Usually worth repairing?
Air leak (fittings/lines)	Hissing, slow refill	Tighten, reseal, replace fitting	Yes
Check valve leak	Air leaks at/inside check valve	Clean/replace check valve	Yes
Pressure switch problem	Won’t shut off, won’t restart	Replace pressure switch	Yes
Pump wear	Low output, slow build	Rebuild pump	Sometimes
Tank leak/weld leak	Won’t hold air, visible rust	Replace compressor	No

Why the tank condition matters most

The tank stores compressed air under high pressure. The troubleshooting chart for this model calls out “air leaks in air tank or at air tank welds” as a defective air tank condition. In real-world terms, that means the safest, most cost-effective path is replacing the unit rather than trying to patch the pressure vessel.

Safety steps before you decide or start any repair

Follow these basics from the owner's manual:

• Turn the compressor OFF.
• Unplug or disconnect electrical supply.
• Bleed the tank and hose pressure completely.
• Let the pump/head cool down before touching metal parts.
• Keep guards/covers in place; moving parts can cause injury.
