On our unit the control knob became stuck. Where can I get a new control knob? Do you happen to know the part number?

I used a hair dryer and that did the trick, but am wondering if WD 40 would work as well. I went online e with the company and they want $2.00 for tech advice which is dumb to me. At first I thought it was the locking device on top; it is actually the pulse switch and my machine is just over a year old.
