KitchenAid KSM150PSGR1 mixer Parts

Yes. The KitchenAid KSM150PSGR1 is an older Artisan tilt-head stand mixer model, and it is typically no longer produced as a current, actively marketed model. Even when a model is discontinued, we still support repairs by helping you match the correct replacement parts using the KSM150PSGR1 owner's manual.

What “discontinued” means for parts and service

A discontinued model usually means the manufacturer has moved on to newer model numbers, not that your mixer is obsolete.

• Many wear items and internal drive parts remain available for years.
• Some cosmetic pieces (color-specific housings, trim) can become harder to source.
• You can still troubleshoot and maintain performance using the same safety and operating guidance.
• Repairs are often practical because this mixer design is serviceable.

Quick checks to confirm you are ordering the right parts

Before ordering, we recommend confirming the exact model and symptom so you do not replace the wrong component.

• Verify the model number on the mixer’s label matches KSM150PSGR1.
• Identify whether the issue is mechanical (grinding, slipping) or electrical (won’t start, surging).
• Check for grease leakage around the planetary area.
• Note whether the speed lever feels loose or does not hold position.

Common repair parts for this model

If your KSM150PSGR1 has grinding noises, stalls under load, or clicks during mixing, the drive train is a common place to start.

Symptom	Common area	Example part for KSM150PSGR1
Grinding/clicking under load	Gear train	Stand mixer worm gear WPW10112253
Oil/grease seepage	Gear case lubrication	Stand mixer grease W11200218
Speed won’t hold steady	Speed control	Plate-ctrl WPW10119326

Why it matters

Knowing the model is discontinued helps set expectations: you may see fewer “new in box” mixers sold under KSM150 numbers, but you can still keep your KSM150PSGR1 running smoothly with the right KitchenAid parts and basic maintenance.

The KitchenAid stand mixer model KSM150PSGR1 uses a 4.5-quart or 5-quart stainless steel bowl (tilt-head style). We recommend confirming your exact bowl capacity and fit details in the KSM150PSGR1 owner's manual.

What “4.5 or 5 quart” means for this mixer

KitchenAid lists this model family as compatible with either bowl size, depending on the specific bowl and accessory set.

• 4.5-quart bowls are common on Classic-style tilt-head mixers
• 5-quart bowls are common on Artisan-style tilt-head mixers
• Both sizes use the same general tilt-head bowl mounting style (bowl clamping plate)
• Capacity affects batch size (cookie dough, bread dough, whipped cream)
• Bowl size does not change the mixer’s speed settings, but it can change how full the bowl should be during mixing

How to confirm the bowl size you have

Use these quick checks before ordering a replacement bowl.

• Look for stamped or printed capacity markings on the bowl (often on the bottom)
• Compare your bowl shape and handle style to the illustrations in the manual
• Verify your mixer model number is KSM150PSGR1 (from the model label)
• If your bowl is loose or won’t lock, inspect the bowl base and clamping area for wear
• If the beater hits the bowl, adjust beater-to-bowl clearance per the manual

Common bowl options for KSM150PSGR1

Bowl description	Typical capacity	Best for
Stainless steel bowl (tilt-head)	4.5 qt	Smaller batches, everyday mixing
Stainless steel bowl (tilt-head)	5 qt	Larger batches, frequent baking

Why it matters

Using the correct bowl capacity helps prevent overfilling, improves mixing performance with the flat beater or wire whip, and reduces strain on internal drive parts like the worm gear.

The most common issues we see with the KitchenAid KSM150PSGR1 stand mixer are: it will not start, it overheats under heavy mixing loads, it makes a “new motor” odor, and the beater can contact the bowl if the clearance is out of adjustment. Use the KSM150PSGR1 owner's manual troubleshooting section to confirm the right fix.

Common symptoms and what they usually mean

• Mixer will not start: power issue, overheated motor protection, or an internal electrical/control problem.
• Stops during heavy mixing: the motor may be overheating; cooling time is part of normal protection.
• Warm top housing: normal under heavy loads and extended mixing.
• Pungent odor when new: common with electric motors, especially early in ownership.
• Flat beater hits the bowl: beater-to-bowl clearance needs adjustment.

Quick checks we recommend first

1. Unplug the mixer, then plug it back in firmly.
2. Check the outlet and your home fuse or circuit breaker.
3. Turn the mixer off for 10 to 15 seconds, then restart.
4. If it still will not run, let it cool for 30 minutes, then try again.
5. If the beater contacts the bowl, stop mixing and adjust clearance per the manual.

Parts that commonly relate to performance problems

If the mixer runs inconsistently, has trouble maintaining speed, or makes gear noise, these model-matched parts are often involved:

Symptom	Common area	Example part for KSM150PSGR1
Grinding/clicking under load	Gear train	Stand mixer worm gear WPW10112253
Speed surging or weak control	Speed control electronics	Stand mixer phase control board WPW10325124
Needs regreasing after service	Gear case lubrication	Stand mixer grease W11200218

Why it matters

Continuing to mix when the unit is overheating or when the beater hits the bowl can damage the gear case, wear the worm gear faster, and affect mixing results. Correct clearance and proper cool-down time protect the motor and drivetrain.
