Product review (5 stars): Works with my Caloric oven, model RSR363
I replaced the original igniter about 15-years ago.  This time, it was just as easy and has been working fine for the past 2-months.

Tip-1:  When I bought my first replacement, I remember the clerk telling me that igniters are very sensitive and that if I do not touch the piece that heats-up then everything would be fine.  He might have been correct, because I have successfully replaced 2-igniters in 2-attempts.

Tip-2:  On my caloric oven, the oven's model number (and much more) is on a silver label that is attached to the frame, in the front, lower-right corner, below the oven (i.e., behind the metal apron, just under the oven door).  To remove the metal apron, simply pull it up and out.
