Barbara G Alameda , CA July 25, 2014 Appliance: Whirlpool LLT8233AW0 Whirlpool Washer Llt8233aw0: My washing machine timer knob came off and couldn't be put back on. How to replace Washer Timer Knob. I had to replace it. Part of the part was still in the washing machine. Got the serial and model numbers and a chat person at AppliancePartsPros helped me match a part to the machine. It arrived 1 1/2 days later. I was able to unscrew the part still in the machine and screw the new part on and I was back in business. My washing machine is about a 1953 Whirlpool model. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
