Kenmore Elite 11631150311 vacuum cleaner Parts

To change the belt on your Kenmore Elite upright vacuum model 11631150311, we remove the power nozzle base plate, slip the old belt off the motor shaft and brush roll, install the new belt, then reassemble and confirm the brush roll spins freely. Use the 11631150311 owner’s manual for the exact screw and cover locations.

Safety first

• Unplug the vacuum before starting (never service it while plugged in).
• Let the motor cool if you were just vacuuming.
• Work on a flat surface with good lighting.
• Keep screws and clips in a small cup so nothing gets lost.

Belt change steps (typical Kenmore upright procedure)

1. Unplug the vacuum and lay it back to access the underside.
2. Remove the bottom plate (usually several screws or quarter-turn fasteners).
3. Lift out the brush roll (agitator) and slide the belt off.
4. Loop the new belt around the motor shaft first, then around the brush roll.
5. Reinstall the brush roll; rotate it by hand to make sure it turns smoothly and the belt tracks straight.
6. Reinstall the bottom plate and tighten fasteners evenly.
7. Stand the vacuum up, plug in, and test on carpet for normal brush action.

Quick checks if the new belt breaks or slips

• Brush roll is jammed with hair or thread.
• Bottom plate is not seated correctly and rubs the brush.
• Belt is twisted during installation.
• Something is blocking airflow; check the hose for clogs (a damaged hose can also reduce pickup). If needed, replace the vacuum hose KC84PDWFZV07.

What you’ll typically need

Item	Purpose
Phillips screwdriver	Removes base plate screws (common on uprights)
Scissors or seam ripper	Cuts hair/thread off the brush roll
New belt (correct fit)	Restores brush roll drive

Why it matters

A worn or stretched belt reduces brush roll speed, which lowers carpet cleaning performance and can make the vacuum sound different. Replacing the belt restores agitation and helps prevent overheating from a stalled brush roll.

Your Kenmore vacuum’s model is printed on the model and serial number plate on the machine; for this Kenmore Elite upright vacuum, the model number format looks like 116.31150311 (often shown without the dot as 11631150311). Use the exact model number from that plate when ordering parts or requesting service details.

Where to find the model number on the vacuum

Look for the Model and Serial Number Plate on the vacuum body (not on attachments). Common places to check:

• Back of the main vacuum housing near the power cord wrap
• Lower rear area near the base/nozzle
• Inside the dust compartment or behind a cover panel
• On the underside of the vacuum (tip it back safely and look underneath)

If you have the paperwork, the model number is also recorded in the 11631150311 owner’s manual.

How to record it correctly (so parts match)

Kenmore model numbers are easy to misread. Use these tips:

• Copy the full number exactly as printed (include all digits)
• If you see a dot (example: 116.31150311), record it both ways; parts lookup typically uses 11631150311
• Write down the serial number too; it helps confirm production details
• Take a clear photo of the plate before the label wears

Quick check table

What you see	What to enter for parts lookup	Why
116.31150311	11631150311	Dots are often omitted in online lookup
11631150311	11631150311	Exact match for this model page

Why it matters

The model number determines the correct fit for key items like the hose, filters, and electrical components. Even small model-number differences can change which vacuum hose or vacuum exhaust filter fits.

If you are replacing a damaged hose on this model, match it to the correct part listing such as the vacuum hose KC84PDWFZV07.

The Kenmore Elite upright vacuum model 11631150311 does not list a specific suction-power rating (watts, kPa, or air watts) in the available Use & Care information; we focus on restoring full airflow performance through proper assembly, filters, and clog removal. For model-specific operating details, use the 11631150311 use & care guide.

What you can use instead of a suction “number”

Because upright vacuums are often not rated the same way across brands, the most reliable way to judge suction on the Kenmore Elite 11631150311 is airflow performance at the hose and floor nozzle.

• Strong pull at the hose but weak at the nozzle usually points to a nozzle or brush path restriction.
• Weak at both hose and nozzle usually points to a clog, a leak, or a restricted filter.
• A sudden drop after a few minutes can indicate the motor protection system reacting to restricted airflow.

Quick checks to restore maximum suction

Unplug the vacuum before checking for clogs or opening covers.

• Check the hose for blockages and cracks; replace if it is split or collapsing (see vacuum hose KC84PDWFZV07).
• Inspect the dust compartment area for a poor seal or debris buildup.
• Replace a dirty or restricted exhaust filter (see vacuum exhaust filter KC38KDWCZV07).
• Confirm the hose is seated firmly in its holders and connections.
• If suction stops, let the vacuum cool unplugged so the thermal protector can reset.

Common symptoms and what they usually mean

Symptom	Most common cause	What to do first
Low suction everywhere	Clog or restricted filter	Check hose path; replace exhaust filter
Good hose suction, poor floor pickup	Nozzle airflow restriction	Clear nozzle and brush path
Vacuum shuts off during use	Thermal protector tripped	Unplug and cool; then recheck for clogs

Why it matters

Suction “power” is only useful if airflow is unobstructed. A partially clogged hose, a leaking connection, or a loaded filter can make a high-performing vacuum clean like a weak one, and it can also trigger the thermal protector.

On Kenmore Elite vacuum cleaner model 11631150311, loss of suction is almost always caused by restricted airflow: a full dust bag, clogged filter, or a blockage in the hose or clean-out path. Restoring airflow (bag, filters, clogs) brings suction back.

Quick checks that fix most “no suction” problems

• Unplug the vacuum before any inspection.
• Replace the dust bag if it is full or packed.
• Check and replace clogged filters (especially the exhaust HEPA-style cartridge).
• Inspect the hose and clean-out port for a blockage.
• If suction changes pitch, the by-pass valve may be opening due to low airflow.

Step-by-step airflow troubleshooting (in the right order)

1. Dust bag first: A full bag is the most common restriction. Install a new bag and re-test.
2. Filters next: If suction is still weak, remove and inspect the exhaust filter cartridge; replace it if dirty or clogged.
3. Remove clogs: Check the clean-out port and extension hose for debris. The manual’s “Removing clogs” section walks through hose removal and clearing the path.
4. Listen for the by-pass valve: This model uses a by-pass valve to prevent overheating; it can open when airflow is restricted (full bag, clogged filters, or a clog).

Parts that commonly affect suction on this model

What you notice	Likely cause	What to do
Weak pickup everywhere	Full bag or clogged filter	Replace bag; replace exhaust filter
Good suction at base, weak at hose	Hose blockage or leak	Inspect/clear hose; check connections
Loud change in sound, hot smell	Airflow restriction triggering by-pass valve	Clear clogs; replace bag and filters

If you need a model-specific diagram and the exact access points, use the 11631150311 use & care guide. If the hose is split, crushed, or leaking air, replace the vacuum hose KC84PDWFZV07. If the exhaust filter is clogged, replace the vacuum exhaust filter KC38KDWCZV07.

Why it matters

Suction loss is an airflow problem. When airflow drops, cleaning performance falls and the vacuum can run hotter; this model’s by-pass valve may open to protect the motor, which is a strong clue you need to clear restrictions.
