All the rings heat up to level 3 and cut out when the temperature is reached ok. Then from level 4 onwards they just stay on red but seem not to get any hotter? Thanks Steve Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic. Log In Username: Password: Keep me signed in Log In
