Craftsman 2x20Volt (Model CMCMW220 or CMCMW220P2)Brushless Lawnmower How to Fix if it Will Not Start 

Recycled the old gas lawn mower after last season. Thought I'd try the battery mowers. This one was just perfect, until, out of the blue, it wasn't. 😞 Thank you very much for this video!! You saved me from trying to find a repair person. 🙂

you should be getting a commission from craftsman was on hold and emails all day with support I could not find that safety switch and was about to return it to the store glad I found your video you would think that is relevent info enough to include in instructions or even put a warning label on the mower... bad practice on their part. Thanks for posting 👍👍

Just want to say I really appreciate you taking the time to share this. Really saved my bacon

Thanks brother u just saved me a trip to lowes

Thank you so much for the information. I had replaced my lawnmower blade and when I went to start it. It was dead. I never noticed that switch cuz it blended in so well. It was 1 month out of warranty. So I thought it was a warranty gremlin. 😂 I’m good to go now. Thx you the man! 🤘🏽

Thank you You saved me a ton of time I was getting ready to start taking it apart

Thank you! Great video. Now our 2 year old machine works again!!!!

Thank you!!! You are amazing. Push the button and the pull the handle lever in.

Mine still isn’t working after that 😭 this is the second one I’ve had too. Anything else it could be? The batteries are charged

Thank you for this video. Of all the videos I watched - this is the one I needed.

If I could like this 1000 times, I would. Thank you for putting this information out there. It helped me.

We were having the same issue, but it wasn’t the safety lock out lever. It was the button on the side of the handle that you push before pulling the lever down to start it. Seems on ours, you really have to push that button firmly and with even pressure before pulling the lever down to start it. Maybe the button has become a little worn. Might be worth a try for you all that this video didn’t work for.

Thank you sooo much .I was fixing to go buy a new one .YOU WERE RIGHT.BLESS YOU

This didn't work on my unit. The interlock is on the up position and I still don't get power. The lawnmower sucks

Thank you SO much for this video. We’ve had ours for a couple months, so unsure how this interlock got depressed, but that totally fixed the issue.

Ive had mine in the shed for 4 months now and was unable to return to store so you saved my ass from the wife killing me

This didn't work for me. The thing is still dead as a doornail. I pulled it up as much as I can. I can't pull it up anymore

Thanks for this because damn if I didn't head straight down in the garage to see if it was the problem, and it was!

I just bought mine month ago and today when I'm gonna use it won't turn on. I tried everything and it's still not working. Someone help me if can. Thanks

It worked! Thank you!!

This dude spent 8 minutes in what could have been a 30 second video.

Fiddling with a safety lock beats the living hell out of messing with oil, spark plugs, screwing with the rip cord and your shoulder

Thank you so much for posting this. Very public-spirited of you. Unfortunately, my safety switch broke so severely even after popping it out, the cut-out remained in place and it won't work. I have to buy a new mower. But you saved me the cost and time of getting someone to repair this, since I now know it is permanently broken. Getting a new one this week--it certainly won't be a Craftsman! Again, much appreciated.

Doing the good work here 👏

My safety is out but it’s still not working. There no tension in the metal handle and it’s not starting

Your the Freaking truth man thank you saved us money today

Thank you for the video. it lead me to the issue I had. the lever that pushes in even when out the mower would still not start. If you open the handles fully then push the lever down then look at the spring behind the lever. If the spring in not totally compressed back towards the handles the mower will not start. I pushed the spring back towards the handle the spring locks in place once it is locked in place and the lever is out then the mower will start.

Thank you. It was going to go curbside.

Well that is why I am going to try now, was cutting yesterday and it stopped working, was hoping I didn't have to take it apart

Thank you. I’ve been using RU-vid since the old school original iPhone days. I almost never comment. But I have to say, thank you. That was my issue. I’ve had the mower for 4 YEARS and haven’t ever folded down the push arms. It worked out of the box for me, and hast stopped, ever. Until I broke the back level adjuster and replaced it. Set the mower back up and went to use it and bam. Nothing. Took apart the handle, battery connect points, looking for a blown fuse, nothing. Never even know about that switch. Thanks again man. Totally helpful.

this video is so needed for owners of this mower!! thank you so much!

Thanks bought used great price because would not start you advise works starts right up.

Mine just stopped working out the blue. I pray this is my issue! Thank you

Quit i/2 way through the first mowing. Daughter bought the thing. I would never buy a modern Craftsman product, I own Craftsman power tools that I bought in the 1970s, and with new brushes, they still run fine, I have 40-50-year-old C'man wrenches that are still great. New stuff is not the same. Too bad. It was once a quality product. By the way thanks for the tip. That is not this mower's problem. Going to disassemble the safety mechanism assembly and see what's up in there.

What's the difference between the 220 vs 220P2?

Bro, thank you! I start disassembling it but thought there had to be an easier explanation. Thank you!

When I hold down the side button and pull back the red lever I don’t get a click sound anymore and my mower refuses to start. Any advice on that ?

Thanks! I folded it up and was wondering why it somehow stoped working!!! Your a lifesaver!!!

I hit a high patch of grass and it shut down and wouldnt start again. I gave it a rest, came back and smoke started coming from under the red cover....

Mine still won't start and I don't know why

Just bought mine last weekend. I folded it up when I was done and went to use it today a week old and it wouldn't turn on. Thank god I found this video because I was going to take it back. My switch was stuck down. It does have a spring but when its pressed all the way down it gets stuck. I have to actually stick a little screwdriver under it and pop it back up.

The new machines don't have this issue anymore, it now has a spring inside. My machine will not start. :(

For the P2 I’m struggling trying to find the interlock

Amazing that Craftsman themselves sent me to this video. Sheesh.

Thank you for taking the time to make this video. I purchased this mower and returned it because just like you said I used it once and after putting it away and bringing it back out a few weeks later it would not start. After a long struggle with Lowes I got an exchange and the same thing happened again, the thing would not start. Now that I know that switch sticks I'm thinking of returning this one as well.

Does anyone know the measurements for the discharge chute?

My safety spring is out and it's still not turning on any suggestions

To do my lawn at home I would probably need 4 9ah bats

Model CMCMWSP220 2x20V MAX* Self‑Propelled Lawn Mower. Any advice for this model not staying on? cuts off after 2 to 3 minutes?

Thank you very much for this!I seen many reviews people saying they stored it after using and wouldn't work again,this is why!!THANK YOU AGAIN very helpful!

You probably just saved me a bunch of money, I'll check tomorrow! Thanks! 🙏

Looks like a simple small yard mower

The safety interlock is all the way up and still don't work! On mine this interlock returns by itself and don't start. It's anything else to put it to work?

Thank You, this is a life saver, I bought it recently, unboxed, charged the batteries for 1 hour, took it to the lawn, it never started, searched couple of Videos, but no one clearly mentioned about this crappy interlock thing. I packed it to return, now I might keep it. Nice useful video 👍

I Just Bought Mines On Memorial-Day, I Haven’t Used It Yet Due To The Rain…However, Thank You For This Information….🙌

Feeding the algorithm thank you for the help

Thank you so much.

You're a hero, sir.

I said it saved me me but the mower stopped the second time I tried after adjusting level. Can’t get it started again. Interlock is up

Man thank you I got it back working!

I bought mine a year ago and it already does not work. It starts but when I try to push it on the grass it stall. Any ideas?

Just being curious I found this video after already fixing it! Same problem. Took the top and handle off to Ohm all the wires out until I found 2 little green wires😂

You're the man! Thx bro

It works for us. Thank you for this video which saved us a lot of time. My friend gave us this used lawnmower and we couldn’t figure out how to get it started. Thanks again.

Use 9 ah for bigger yard

Mine will not start at all. Did the little trick. Nothing… it just clicks like it wants to start. Batteries are fully charged. Any suggestions anyone

Thanks! I knew I saw or touched that before but didn't remember to mess with it again

You are the man THANK YOU SO MUCH!!! I knew that it had to be something simple!!! I’m so happy for your video, I really appreciate you sharing. May you always be blessed!!

Where is the mower's date code?

You just kept mine out of a dumpster. Used it one time and stored it for the winter... read the whole stinking manual and didn’t come up with this. Much appreciated.

Have you thought about using 9ah batteries 👀🤔

Thank you so much for this!! I was getting pretty aggravated!!

My stupid safety interlock is popped up. it won't lock down. My lawn mower keeps stopping. Help!

Mine didnt trigger until after a couple months of use. Was about to take it back till I came across your video. Thank you.

Thank you, you just saved me a lot of hair pulling 🙏😁

Shuld get the 60 volt

First one I bought wouldn't start. Exchanged it. Second one wouldn't start. Took me an hour to figure out this was the problem. Has to be costing Craftsman tons of money on returns when all they need to do is put it in the manual or use a sticker by the safety switch.

Thank you for making the video it was very helpful. They need to be better with their documentation. And actually they should make that a red switch so it is easily noticed.

Every time I see an electronic lawnmower I always want to engine swap it

This happened to me a when I brought it out from storage after the winter. Thank you for this info.

I just got one of these. Haven’t used it yet. Thank you so much.

Thanks man. I never would have figured that out.

Years later and still helping .. Thanks man.

Is there any vids on here on how to take the wheels off?

This video saved me from the wraith of my wife. Thank you!

The blades fell off while I was mowing.....I put them back on, but now it won't spin the blades. Can you show me the parts around the blades? I may be missing a part? When I go to start it, it makes a small sound, but blades don't spin. The blades can be spun easily by hand, like there is a part missing. I need to see what holds the blades on.

Really saved my ass. Thanks

Well done. Saved me hours of trouble shooting!

Man this helped a lot. Thanks

Thank you so much you are a lifesaver. ❤

Thank you thank you thank you!

Wish I could get one of the returned units

yeah what happens when i do that and it still doesn't work?

Im having a issue with it stopping once I start to mow then I have to let is sit then its dead ? Mower is Garbage and only had it one season

The back wheel adjuster broke, how can I fix this?

Thanks for ur video helps a lot

Oh my God. Glad it was a simple fix. Saved my day

Love you

Super helpful!

I have tried this with no luck. I can feel the motor twitch and then nothing. Only used it once!
