Product review (5 stars): Just what we needed!
Saved us a service call and/or a new oven!  The GE oven that was in the house when we bought it often threw weird errors.  Then it just went insane one night and kept going into self-clean mode (almost ruined my dinner but I caught it in time).  Husband was ready to get a new oven, but I Googled and decided to give the sensor replacement a try.  It's working fine again!
