What is the typical lifespan of a gas snowblower?
A gas snowblower typically lasts 10 to 15 years. For your Craftsman snow thrower model 944528117, consistent seasonal maintenance (oil care, cleaning, correct storage, and timely belt or shear bolt replacement) is what keeps it reliable year after year; see the 944528117 owner's manual.
Most gas snowblowers land in the 10 to 15 year range; heavy, wet snow use and poor off-season storage shorten life, while routine upkeep extends it.
- Longer lifespan: regular oil changes, clean storage, correct skid shoe height, and prompt repairs
- Shorter lifespan: running low on oil, water intrusion during cleaning, storing with fuel indoors, and repeated auger jams
- Highest-wear items: belts, shear bolts, friction drive components, and chute/auger hardware
The manual for this model calls out several practices that directly protect engine and drive life.
- Run the machine a few minutes after throwing snow to help prevent freeze-up
- Clean the housing after each use; avoid spraying water into the engine area
- Use the correct oil viscosity for temperature (commonly SAE 5W-30 or 10W-30; synthetic 5W-30 is also common)
- Check spark plug condition and gap during tune-ups
- Store in a clean, dry area; follow the manual’s extended-storage steps
Use this as a practical decision tool when you are weighing repairs on an older unit.
| What you’re seeing | Most common cause | Typical fix |
|---|---|---|
| Auger stops under load | Worn or stretched belt | Replace the snowblower auger drive belt 532408007 |
| Auger jams and then will not turn | Shear bolt broken (designed to fail) | Replace the snowblower shear bolt 588077502 |
| Poor snow intake, scraping issues | Skid shoes set wrong or worn | Adjust or replace skid components |
| Drive feels inconsistent | Friction drive wear or contamination | Inspect drive system; keep friction surfaces dry |
A snowblower’s “lifespan” is mostly about preventing engine wear (oil level and correct oil type) and avoiding drive damage (belt condition, no water intrusion, and proper storage). Those basics cost little and prevent the expensive failures.

Where can I find my snowblower model number?
On your Craftsman snow thrower, the model number is printed on the product identification label. For model 944528117, you will typically find that label on the rear of the unit between the wheels, or on the side of the frame near the auger housing. For diagrams that match the label location and parts breakdown, use the owner's manual.
Check these spots first (wipe off snow, salt, and grime so the label is readable):
- Rear of the snowblower between the wheels (most common)
- Side of the frame near the auger housing
- Near the handle support area or console panel
- On the chassis close to the drive system
We recommend recording the full identification information exactly as shown:
- Model number (example: 944528117)
- Product number or serial number (if listed)
- Any revision or type code on the same label
The model number ties your snowblower to the correct parts diagrams and repair parts list. Even small differences can change which auger belt, shear bolt, or gearbox assembly fits.

What is the most common reason snowblower won't start?
The most common reason a Craftsman snow thrower like model 944528117 will not start is a fuel-related issue, especially stale gas or water-contaminated fuel. We also frequently see no-start problems caused by the safety ignition key not being fully inserted, the ON/OFF switch being OFF, or a spark plug issue (wire off or plug worn).
- Insert the safety ignition key fully until it clicks (do not turn the key).
- Set the ON/OFF switch to ON and make sure the throttle is not in STOP.
- For a cold start, set the choke to FULL.
- Confirm you have fresh fuel in the tank (do not use last-season gasoline).
- Check the spark plug wire; it must be firmly connected.
| Symptom | Most likely cause | What to do next |
|---|---|---|
| Engine will not fire at all | Safety key out, switch OFF, spark plug wire off | Re-seat key, switch ON, push wire onto plug |
| Starts then dies or runs rough | Stale fuel or water in fuel | Drain old fuel, refill with fresh fuel |
| Strong gas smell, won’t start | Flooded engine | Choke OFF, do not prime, pull recoil several times |
| Hard starting in cold | Incorrect starting steps | Follow the start procedure in the 944528117 owner's manual |
Stale fuel is the number one repeat offender because gasoline breaks down and leaves varnish that can gum up the carburetor.
- Do not store gasoline from one season to the next.
- Use clean, fresh fuel from a non-rusting gas can.
- If you use fuel stabilizer, run the engine long enough for treated fuel to reach the carburetor.
- Before storage, remove the safety ignition key and store it in a safe place.
A no-start condition is usually a simple setup or fuel problem, but repeated starting attempts with bad fuel can quickly lead to carburetor fouling and longer repair time. Following the correct choke and priming steps from the 944528117 owner's manual prevents flooding and reduces wear on the recoil starter.
If you need replacement parts for common no-start repairs (for example, drive system service after a long storage period), you can order parts for model 944528117 from the parts list for this model, or search by model number on Sears PartsDirect.

How to tell year of CRAFTSMAN snowblower by serial number?
For a Craftsman snow thrower like model 944528117, the year is determined by the serial-number format used on your unit. We match the format on your ID tag to the correct decoding method, then read the year digit(s) in that pattern; the 944528117 owner's manual helps you confirm where the model/serial label is located.
Look for the model/serial label on the frame or rear of the unit (location varies by build). Once you have the serial number, check which pattern it matches:
- Format A (5th character = year in the decade): a mixed letter/number string where the 5th character is a single digit for the year within a decade.
- Format B (MTD-style date code): the first 5 characters encode the build date; the letter indicates the month, followed by digits for day and year-in-decade.
- Engine code (engine date, not the snowblower date): the engine has its own code that can indicate engine manufacture date; use it only as a supporting clue.
If your serial number matches this style, read:
- 1st character: product type
- next characters: month/day (varies by tag)
- 5th character: year in the decade
Example: If the 5th character is “1”, the unit was built in a year ending in 1 (for example 2001 or 2011). Use the machine’s features and purchase timeframe to choose the correct decade.
If the first character is a month letter, use:
- Month letter: A = Jan through L = Dec
- Next digits: day of month
- Final digit in that group: year in the decade
| What you see on the tag | What it usually means | What year you get |
|---|---|---|
| 5th character is a single digit | Year within a decade | Year ends in that digit |
| First character is A through L | Month code (A=Jan, L=Dec) | Year ends in the last digit of the date code |
| Separate engine code on engine | Engine build date | Use as a cross-check only |
Knowing the correct year helps us match the right OEM parts and diagrams for your Craftsman 944528117, especially wear items like the snowblower shear bolt 588077502 and snowblower auger drive belt 532408007.

Is it worth fixing a snowblower?
Yes, fixing a snowblower is worth it when the repair restores safe, reliable operation for less than about half the cost of replacing the machine. For a Craftsman snow thrower model 944528117, routine wear items (belts, shear bolts, skid shoes) are normal maintenance and usually make sense to repair.
- Compare total repair cost (parts plus labor) to replacement cost; repairs under ~50% are the better value.
- Fix it if the engine runs well and the auger and drive systems are otherwise solid.
- Replace it if the frame, auger housing, or major drivetrain components are badly damaged.
- Repair immediately if you have abnormal vibration; it is a warning sign and the unit should be inspected before further use.
- Prioritize repairs that restore safety features and proper belt engagement.
These are typical, high-impact fixes that often bring performance back quickly:
- Replace a worn auger belt (loss of throwing power); see snowblower auger drive belt 532408007.
- Replace broken shear bolts after hitting a foreign object; see snowblower shear bolt 588077502.
- Adjust or service chute controls if the chute will not aim correctly.
- Lubricate drive and auger components as part of seasonal maintenance.
| Repair type | What it fixes | Typical value | When to reconsider |
|---|---|---|---|
| Belt replacement | Auger or drive not engaging | High | Multiple pulleys or shafts are damaged |
| Shear bolt replacement | Auger stops after impact | Very high | Auger/gearbox is seized or bent |
| Skid shoe/shave plate service | Scraping, poor clearing | Medium | Auger housing is cracked or warped |
| Gearbox replacement | Grinding, no auger drive | High but costly | If combined with major engine issues |
A snowblower that is slipping belts, missing shear bolts, or vibrating abnormally can be unsafe and can cause additional damage. The manual also calls out stopping the engine and disconnecting the spark plug wire before inspections or repairs, especially after striking a foreign object.
- Review the maintenance schedule and seasonal checks in the owner's manual.
- Inspect belts for wear at least once each season; replacing a worn belt is often the most cost-effective fix.
- Price out the specific parts you need from the parts list for model 944528117, or search by model on Sears PartsDirect.
