have a Heavy Duty 4423 that just doesn't run. I've looked for a fuse but I can't find one. I know there is electric power up to the end of the power cord where it plugs on the machine but it wont run. Please help!

Have you done a thermostat delete? By flipping it backwards

Replaced that, and the fuse. No success. 2011 Gmc Sierra

thank you. i've had this machine for years, had it back to the shop once for this already and was facing another trip. Once I found your video, i was sewing again in 10-15mins

Thank youuuuu!!!! I managed to fix mine after watching your video.

I've already replaced everything and I'm still being thrown away by the P0011 Code that I can do?

Thanks for the insight…👍🏾

Sir. I could kiss you right now.

Absolutely beside myself... 'sew aggro' over my 4423 yesterday. I literally told my husband, "this is like buying a car and having to be a mechanic instead of a driver." This video is so well done- filmed close up- so viewers can actually see what things are supposed to look like; and the timing of the explanation is bar none. Looking forward (again) to sewing, as I now have renewed hope.

Mine fell off in neutral, my park brake cable broke next... on a sloped driveway. I found at first this new bushing didn't snap into the groove on that pin. The groove had gunk and rust so I filed it deeper and sharper, put grease inside the bushing when pushing it on and then used a blunt screwdriver to make sure the bushing lip was pushed firmly into the groove all the way around the pin... all good.

The shifter pin is definitely worn out but Dorman Products are not the best

Can I do this on stands on a driveway?

Ride it pls

This was so helpful. Thank you so much!

Could you see “brush stroks” in the clear after you finished?

Thanks for the review of the Power Blast Plate. I notice that you have a lift in the garage. What type? Looking for one for my garage or a new shop.

Great video. Changed those exact parts now my 6.0 has a ticking like a lifter. Didn’t have that before. Also at 1st startup it’s running rough. No codes now though. Any ideas?

I have same problem still don’t know how to fix it 🌹🇨🇦

I replaced the stop light switch on my 2011 Tahoe. Cruise control still doesn't work. Anymore suggestions?

Crazy part I still don’t know which one it is you replace so many parts at one time you couldn’t really rule out which one

convert to a 7.3 ford fan clutch and add a mishimoto trans cooler, towing here in Colorado mountains I barley see 200 degrees, outting around town 175-185 max.

Thank you so much for this video. I’m sorry about the frustration you went through to get to this point, but I very much appreciate your efforts. I was having this issue also. Thankfully my husband is also mechanically inclined and can see this is the problem on my model and is working to address it with the help of your explanation. I was so worried because it is such a challenge to find troubleshooting solutions. It would probably have been easier & more cost effective to get a new machine than the time, travel, & costs of getting it repaired all except for your clear and detailed video.

ty for the video I realized, someone stole my presser foot lol

can anbody help please? when i push the catch tooth with screwdriver it automatically triggers the hand wheel and needle moves/raises up

OMG the comments you are making before even starting the fix, is the EXACT same comments I have been saying! TY for reiterating my thoughts, just verbally :)

You know what Imma do?? Return this pos machine. If I knew sewing machines at all, I’m sure I would be very happy to see your video and all the comments; but I haven’t sewn in about 20 years and never had to fix a machine in my life. So all I can do is think that this machine is a joke. Glad you were able to help so many people though.

I’m watching what you’re talking about and still have no clue. I know close to nothing about sewing machines. It’s crap that I buy a new machine with a problem right out of the box. Unreal! Thought I had it on some weird thread position I didn’t know about. Turns out, this is a common issue?? Unacceptable.

THANK YOU, THANK YOU. This was so helpful. I wasn't sure how to adjust. But just a little tweek and I could see what you were talking about. Back in business after so much wasted time.

Hey.....did u plug the open holes of the heat exchanger... Where the antifreeze went in

Is the pump critical to the installation? Does the Borgeson 800310 pump have a higher PSI rating?

If I didnt live in Michigan I'd do it...

Why not just use a pin, washer and cotter pin

I really wish u would point at stuff ur talking abt..cus i dont know all the names of the parts

Such a helpful video, thanks so much!!!

hey bro, we want to invite you to review the latest 2007-2014 Cadillac Escalade taillight, how to contact you?

My bushing was missing but had not fallen off, it had a small hitch pin in it. I dont know if its factory but it keeps it from falling off even with the new bushing in it

I have a Brand new machine, my thread is getting caught on the bobbin after picking up thread and its hard to turn hand wheel

Thank you!!!!😂

Thank You for this content!!! I've wasted hours trying to understand what happened to my machine. One minute, it worked fine, and then it started shooting out globs of thread.

Does anyone have a link to the hardwire charge cable? I cant seem to find it on Amazon

Please how can visit thread

instead of the autometer, can you just use a heater plug and the same constant pressure clamp?

For the 14mm coolant plug on the driver side, how about a 14mm replacement oil drain plug. Could get a magnetic tip as a bonus. Getting ready to do this!

How often do these coolers fail? Or at how many miles

I just got my 4423 and it started seizing up an hour after pulling it from the box. I pulled all thread, bobbin, needle, shank, took the case off, disassembled the bobbin case, everything. It made me nuts! About to try this and see how it goes. Thanks!

Hi there on the front of the servo (booster) there is a small angled tube pointing downward under the push rod fitting, what does that connect to if anything and what its purpose ?

Good job to all you go getters I just went easy and bought the little bushing

I'm gonna try this because I'm going through the same problem.

I used zip ties to get my chevy back home. Put on the doorman bushing. Total pain to put in and failed within 5 minutes. Total junk

WARNING: I have a Singer Heavy Duty 6700C. It does not have a belt. Rather, it is direct drive and there is indeed an easy way to adjust it. The rotating part is connected with gears to a shaft with 3 set screws (Allen # 2). The set screws are accessible by a small panel on the bottom of the machine that opens with one screw. If you force the shaft to spin without slacking back the set screws, it will most likely score the shaft and thereafter come more easily out of alignment again.
