Product review (5 stars): Universal Round (Carborundum) Oven Igniter
These igniters are the usual cause of ignition failures. Even if they look like they are working, as they age, their internal resistance prevents the gas valve from opening. This (of this review) round (Carborundum type) and the other square (Norton type), are used in almost every electronic ignition, gas oven and broiler (probably, also water heaters and furnaces). Don't worry about model and part numbers; if it's round it's the Carborundum, if it's square it's the Norton. Just take a look at the oven. It might be necessary to unscrew (usually two screws) the oven floor. --I have bought both of these from Amazon (Seneca Trading). They are not made by the original manufacturers, but seem to fit and work identically, for a fraction of the price.  There is some care required (not too difficult) in removing and replacing them and stripping the wires and properly using the ceramic (heat proof) wire nuts supplied.  No care is necessary regarding wire polarity, as it is only a matter of completing the circuit. There is way more wire provided than normally necessary, so take care to cut it to size; enough to manipulate it for splicing, but not too much to store in the available space. Disconnect the electricity (or take the risk that someone, including yourself, will do something really stupid during your repair). Be carefull, take your time (30-60 min), and you'll have a working oven when you're done. Let the force be with you.---JIM A
