How to Troubleshoot & Replace Frigidaire AP4321740 / 134051003 Drive Belt

Looked on line and found that the general consistences was it was the door switch. Ordered it and a new belt since I was in there any and replaced both and the washer is back working. I also replaced the water supply hoses since they were 10 years old, Hope the washer lasts another 10 years. I did watch some DIY videos on U TUBE that helped a lot. 

I watched videos on the website and took it apart. Put new motor on, also I put new belt even though the original belt was still ok, but I saw a little sign of shredding ...and there! !! It works like brand new washing machine. . Thanks to appliancepartspros.com...It made save a lot of money by doing it myself.. 

REPLACED THE BELT 

Replaced the door latch. I was doubtful that this would solve the problem but I was assured that if it didn't I could get a refund for the part so I ordered it and to my surprise it fixed it. I had a little problem with the boot around the door but I had watched a video on replacing it so I was prepared. 

Washer would only go into high speed spin when drum was empty or very little in it, a few small towels. I replaced the drive motor and drive belt (old belt didn't look bad) but why take a chance and I had everything apart so why not change the belt. I also changed a noisy water pump. The washer is now back on line working and sounding good. 

New belt, works great 

New parts ordered and installed. Hooked everything back up and she's running like a stealth bomber over North Korea.. completely silent 

Replaced broken belt with new belt 

After researching on AppliancePartsPros and another website, both suggested it was most likely to be the door lock assembly. As the machine is already 10 years old, I figured I would replace the drive belt at the same time. What swung me to AppliancePartsPros is that they had embedded videos on their pages showing the repair process. I'm "moderately competent" with repairs if I have instructions to follow. The drive belt was very easy, simply unscrew the back panel and pull off the old belt. The new belt was a bit tighter but a determined spin of the wheel pulled it on tight. The door lock was a bit trickier as the AppliancePros video had a different gasket style which had to be replaced. A quick YouTube search got me one with a similar gasket to mine. Again that repair was very simple. Both were done in 10-15 minutes. I can't tell which piece corrected it since I did both, but machine is back working again. 

Take back off washer with screw driver. Belt was a simple fix. Take off old belt , I watched your video very simple fix.. Next was replacement of drain hose no problem all I needed was a pliers to pinch the clamp. Remove old hose and put on my new part. Thank you for always having the parts I need.
