Product review (4 stars): Works as a replacement for PA020041
My 6-burner Viking stove came with two Tytronics PA020041 spark modules. When one went out earlier this year, I replaced it with another Tytronics unit, however, that one failed after just a couple of months (could have been my fault -- I forgot to connect the ground wire when installing). Anyway, I didn't want to spend another $100, so I gave this one a shot. It works great, however, there are two downsides:

One -- it is a little bigger than the PA020041; it fits into the screw mounts fine, but I had to bend the sides of the metal box that goes over it to get it to fit over the unit.

Two -- it sparks much more slowly than the PA020041; this one sparks about once per second, the PA020041 sparks about 4 times faster.

Otherwise, it's great so far.
