The old style whirlpool knob had 1/4 -20 threads, some of the plastic timer knobs on the newer generation machines, look like the old knobs, but are slotted, and are held on by a black plastic keeper. I suppose if they gave you a newer one by mistake, it might go on, but it would slip because it doesn' t have 1/4-20 threads
to secure it tight. Remove it and see it it has good threads, if not re- order a new one with threads. |
