How to find air compressor model number?
On a Craftsman air compressor, the model number is stamped or printed on the unit’s identification label (often a metal or foil placard). For model 10217224, use that exact model number when looking up parts and diagrams in our air compressor common questions guide.
Where to look on the compressor
Check these common label locations first (wipe dust and oil off the surface so the print is readable):
- On the air tank near the handle, feet, or wheel bracket
- On the pump or motor mounting plate area
- Near the pressure switch cover (where the power cord enters)
- On the rear of the tank opposite the regulator and gauges
- Under a shroud or cover (if your unit has one)
What the label usually shows
Most Craftsman compressor ID labels include several fields. The one you want for parts lookup is the model number.
| Label field | What it’s used for | Use it to order parts? |
|---|---|---|
| Model number | Identifies the exact compressor design | Yes (primary) |
| Serial number | Tracks production run | Sometimes helpful |
| Voltage/amps/HP | Electrical requirements | No |
| Max PSI | Tank pressure rating | No |
Tips to avoid mix-ups
Model numbers can be confused with other numbers printed on the tank or motor. Use these checks:
- Match the full model number exactly (for example, 10217224)
- Ignore patent numbers and casting numbers
- Don’t use the motor model number to search compressor parts
- If the label is worn, try a flashlight at an angle to read stamped characters
Why it matters
Air compressors often share similar tanks, gauges, regulators, and pressure switches across multiple versions. Using the correct model number helps us show the right parts breakdown so you get compatible fittings, valves, and electrical components.

Can I run an air compressor on a 15 amp breaker?
Yes, you can run a Craftsman air compressor model 10217224 on a 15 amp breaker if the compressor’s running amps and startup (inrush) current stay within what that circuit can supply; in practice, many portable compressors run more reliably on a dedicated 20 amp circuit, especially during cold starts or when the tank refills from empty.
What determines whether 15 amps will work
A breaker size alone does not guarantee success; the real limits are motor starting load, voltage drop, and what else is on the circuit.
- Motor startup (inrush) current is much higher than running amps and can trip a 15A breaker.
- Tank pressure at restart increases starting load; a compressor restarting against pressure is harder to spin.
- Extension cords add resistance and cause voltage drop, which increases amperage draw.
- Shared circuits (lights, heaters, shop vacs) reduce available current.
- Ambient temperature affects starting; cold oil-lubricated pumps and stiff seals can raise load.
Quick guidance we use in the shop
If you want the most dependable setup, we treat 20A as the standard for frequent compressor use.
| Setup | Typical result | Best for |
|---|---|---|
| 15A circuit, no extension cord | Often OK for small loads | Occasional use, short run times |
| 15A circuit with extension cord | Common nuisance trips | Not recommended |
| Dedicated 20A circuit | Most reliable starts and refills | Regular use, higher demand tools |
If you must use a 15A breaker
Use these steps to reduce nuisance trips and hard starts:
- Plug directly into the wall whenever possible (avoid power strips).
- Use a short, heavy-gauge extension cord only if necessary (long, light cords cause voltage drop).
- Keep the circuit dedicated while the compressor runs.
- Start with the tank partially drained if it struggles to restart at higher pressure.
- If it hums but will not start, shut it off immediately and investigate the start circuit and pressure switch.
Why it matters
Running on an undersupplied circuit can cause repeated breaker trips, slow starts, overheating, and premature wear on the motor, pressure switch, and start components. For troubleshooting hard-start issues, we use the steps in air compressor won't start.

What are the 4 types of compressors?
The four common compressor types are reciprocating (piston), rotary screw, centrifugal, and axial. For a Craftsman air compressor like model 10217224, you will most often see a reciprocating (piston) design because it fits typical home and light shop air tool use.
Quick breakdown of the 4 types
- Reciprocating (piston): A piston moves up and down in a cylinder to compress air; common in portable and garage compressors.
- Rotary screw: Two intermeshing screws compress air continuously; common in commercial shops needing steady airflow.
- Centrifugal: A high-speed impeller accelerates air and converts velocity to pressure; used for large industrial volumes.
- Axial: Multiple rotating and stationary blade rows compress air along the shaft; used in very high-flow applications.
How they compare (at a glance)
| Type | How it compresses air | Typical use case | What you notice most |
|---|---|---|---|
| Reciprocating (piston) | Piston and valves | DIY, home garage, intermittent use | Louder, cycles on and off |
| Rotary screw | Twin screws | Continuous shop air | Smoother, steady output |
| Centrifugal | Impeller stages | Plant air systems | High flow, complex system |
| Axial | Blade stages | Turbines, specialized industrial | Very high flow, specialized |
Why it matters when troubleshooting or buying parts
Compressor type affects what fails and what you check first. For example, piston units commonly involve valve, piston seal, and pressure switch issues, while screw and centrifugal systems have different service needs.
- If it won’t start, focus on power, pressure switch, and unloader behavior: air compressor won't start
- If it won’t build tank pressure, focus on leaks, check valve, and pump condition: air compressor won't build tank pressure
- If you’re doing deeper pump work, use a rebuild workflow: how to rebuild an air compressor pump

How to read compressor model number?
For a Craftsman air compressor, the most reliable “model number” is the one on the unit’s data label; for this model it’s 10217224. That model number identifies the exact compressor version so you can match the correct parts list and repair information, even if the pump or motor has separate numbers.
Where to find the model number on a Craftsman air compressor
Look for a sticker or metal tag on the compressor; common locations include:
- The air tank near the handle or wheel bracket
- The shroud or frame near the motor/pump
- Near the pressure switch or regulator area
- On the rear of the tank (opposite the gauges)
- Close to the power cord entry point
How to “read” what the numbers mean (what to look for)
Air compressor model numbers are primarily an identifier, not a spec sheet. Still, you can pull useful clues from the label and nearby markings:
- Model number (example: 10217224) identifies the unit family/version
- Serial number helps date and track production runs
- Electrical rating (volts, amps, Hz, phase) confirms power requirements
- Max tank pressure (PSI) and sometimes cut-in/cut-out ranges
- Tank size (gallons) and air delivery (SCFM at a PSI) on some labels
Model number vs. pump/motor numbers (quick comparison)
| What you’re reading | Where it’s found | What it’s used for |
|---|---|---|
| Compressor model number (10217224) | Tank label/tag | Matching the correct parts breakdown and diagrams |
| Serial number | Tank label/tag | Identifying production run and unit history |
| Motor or pump number | On motor plate or pump casting | Motor/pump-specific service info and compatibility checks |
Why it matters
Using the correct model number prevents ordering the wrong pressure switch, regulator, check valve, or gauge style. Small design changes between versions can affect fittings, wiring terminals, and pressure settings.
If you’re trying to decode specs for troubleshooting
Use symptom-based checks tied to what the compressor is doing:
- Won’t start or trips breaker: air compressor won't start
- Won’t build pressure: air compressor won't build tank pressure
- Leaks air: air compressor air leaks
- Pressure won’t adjust: air compressor can't adjust the output air pressure

What is the most common cause of air compressor failure?
The most common cause of failure in a Craftsman air compressor like model 10217224 is poor maintenance that leads to overheating and accelerated wear (dirty intake filter, restricted cooling airflow, moisture left in the tank, and worn seals or valves). These issues typically show up as hard starting, low pressure, or frequent cycling.
Most common failure drivers (and what they damage)
- Restricted airflow and overheating: breaks down internal components and can damage the pump.
- Dirty or clogged intake filter: reduces air volume, increases run time, and raises operating temperature.
- Moisture and corrosion in the tank: weakens fittings, promotes leaks, and shortens tank life.
- Air leaks at fittings/hoses/regulator: forces longer run times and overheats the unit.
- Pressure switch or check valve problems: causes no-start, short cycling, or hard restart.
Quick checks we recommend before assuming “the compressor is bad”
- Listen and look: does it hum, trip the breaker, or run but never build pressure?
- Check for leaks: spray soapy water on fittings, drain valve, regulator, and hose connections.
- Confirm cooling airflow: clear dust from shrouds/vents; keep the unit away from walls.
- Drain the tank: release moisture after use; water left inside speeds corrosion.
- Watch the gauges: a bad gauge can mislead troubleshooting.
Symptom-to-cause cheat sheet
| What you notice | Most likely cause | What to do next |
|---|---|---|
| Won’t start | Pressure switch, check valve, motor/capacitor, low voltage | Follow air compressor won't start |
| Runs but won’t build pressure | Leaks, reed/valves, worn pump seals | Follow air compressor won't build tank pressure |
| Tank loses pressure sitting | Leak at drain valve/fittings, tank issue | Follow air compressor tank won't hold air |
| Safety valve pops | Overpressure control issue, regulator/switch problem | Follow air compressor safety valve keeps popping open |
Why it matters
Most “failures” start as small efficiency problems (leaks, dirty filter, restricted cooling). Fixing those early prevents long run times and overheating, which is what turns a minor repair into a pump or motor replacement.
