A flashing sensing light usually signals a failure with the shift actuator or the lid lock assembly. I recommend entering diagnostic mode to retrieve the specific error code before replacing any parts. Most of the time, the washer simply cannot confirm that the drive system is in the correct position to begin.
Ignore this long enough and you'll end up with a washer that just sits there humming while your clothes soak in cold water. The sensing phase is how the machine figures out load size and transmission position, so when it stalls here, nothing else works. I've shown up to jobs where the homeowner ran the machine a dozen times hoping it'd fix itself, and that usually just makes the shift actuator worse.
OK so here's the deal with this one. The sensing light flashes when your Kenmore top-loader can't figure out where the transmission is sitting. Think of the shift actuator like a little position sensor bolted to the bottom of the gearcase, and when it goes bad, the control board basically shrugs and refuses to move forward. Parts are cheap, honestly, usually under $80, and I'd say about 70% of the calls I get for this exact symptom end with a shift actuator swap and the machine running fine.

Symptoms You May Notice
The washer starts, you hear the motor hum for a few seconds, then nothing. Just sits there with that sensing light blinking at you.
Lid lock clicks two or three times in a row and then stops, which means the machine tried to confirm it locked, couldn't, and gave up.
Cycle stops immediately after you press Start, before it even fills with water.
A faint grinding or clunking noise from the bottom of the machine right during that first few seconds, then it stalls.
Machine won't spin no matter what, even if you try to manually advance the dial to the spin cycle.
Can you reset a Kenmore washer to clear the SENSING-LIGHT-FLASH code?
Unplug the washer from the wall. Wait a full 60 seconds, don't cheat it down to 10. While it's unplugged, press and hold the Start button for about five seconds to bleed off any stored charge. Plug it back in, select Drain and Spin, and press Start. If the error clears, great. If the sensing light comes back within the first minute, you've got a real mechanical failure and the reset won't fix it.
Tools Required for Diagnosis

Service / Diagnostic Mode
With the washer plugged in but not running, rotate the cycle selector knob: Left 1 click, Right 3 clicks, Left 1 click. Complete the sequence within 6 seconds. All indicator lights will flash at once to confirm you're in diagnostic mode. Then turn the knob right until only the Done light is lit, press Start to read stored fault codes.

Frequently Asked Questions
Can I just reset the washer to stop the light from flashing?
You can try it, and sometimes it works if the fault was just a random glitch from a power blip. Unplug the machine for a full minute, hold the Start button for five seconds while it's unplugged, then plug it back in and run a small load. But honestly, if there's a mechanical issue like a worn shift actuator or a cracked lid latch, that flashing light is coming right back. The reset just clears the board's memory. It doesn't fix the part. Think of it like clearing a check engine light without actually fixing the car.
How much does it cost to fix a flashing sensing light?
If you're doing it yourself, a genuine shift actuator for a Kenmore top-loader runs $50-$80 depending on the model. Part number 285671 fits a huge range of them. The lid lock assembly is usually $30-$50. A control board is where it gets painful, those run $150-$250 for the part alone. Call a pro and you're looking at $200-$350 total for a shift actuator repair once you add the service call and labor. Honestly, if your machine is 12+ years old, have that conversation with yourself about whether repair makes sense.
Why does my Kenmore washer get stuck on the sensing cycle?
Because the machine is waiting on a signal that isn't coming. The control board tells the shift actuator to move into position, and then it waits for the actuator to report back with the correct position code. If the actuator's internal gear is stripped, the optical sensor is dirty, or the wire harness connector is loose, that response never arrives. So the board just sits there with the sensing light blinking, refusing to move forward because it won't risk running the motor if the transmission might be in the wrong gear. It's actually a smart safety feature. Just an annoying one.
Is the shift actuator easy to replace for a homeowner?
Yeah, it's one of the easier repairs on these machines. Unplug it, tip it back, pull two screws, unplug the harness, plug in the new one. The whole thing takes maybe 20 minutes if you've never done it before, 10 minutes if you have. Just don't crank those screws down too hard when you install the new one. The plastic boss can crack and then you're buying another actuator. Snug is perfect. Tight is bad. Then run the calibration cycle before you test it with laundry.
Could a bad lid lock cause the sensing light to blink?
Absolutely, and I actually check the lid lock before I even touch the actuator because it's easier to get to. Open the lid and look at the latch housing for any visible cracks. Then close the lid and listen closely. You should hear one solid click. If you hear it click two or three times and give up, or if it makes no sound at all, that's probably your culprit. A new lid lock assembly is only $30-$50 and takes about ten minutes with just a flathead screwdriver. Way cheaper than a shift actuator if that's all it is.
Does the Kenmore sensing light issue affect all model years?
Pretty much any Kenmore top-loader built after 2005 that uses the dial-based control system can show this. These machines are basically rebranded Whirlpool Direct Drive units, so the same shift actuator design shows up across a ton of models. The earlier machines from the late '90s and early 2000s used a different transmission system and you won't see this exact error. If your machine has a round selector knob with LED indicator lights around it, you're in the affected group.
