|06-10-2009||Always? Sweetie I thought I had located a replacement part that had 24v for the secondary winding. Does that explain why there are 4 connections out of the secondary? Taking it from AC and turn to DC by way of some diodes on a connected board? Then it|
Are my questions really that hard, or am I being too intrusive?
I can see lots of imprecise and nonconclusive questions answered, but I'm giving my best to be as precise as possible yet received only a few replies.

|07-10-2009||Just because a transformer has a mess of pins, does not mean it has to use all of them. :wink:
AC out of transformer can be rectified by one diode (half-wave) or by two diodes (full wave). It can also be rectified by four diodes (full wave bridge).|
|07-10-2009||One "set of pins" has 24vac while the other has like 3vac. What is happening is the relays are switching back off after a few mintues. The coil will energize and the oven will get hot but then a few mintues later the relay cuts off? Does that|
