The transformer on the oven control stove board identified as:
LS-A12119-PT
E154515 Z150H
CLASS B (130 C)
LEI-4 0704

Input voltage (1,4) = 110-120 Vac
Output voltages
(5,8)= 16 Vac
(5,7)= 8Vac

What is wrong with it?
Check the primary winding with an ohm meter. If it is open, then I would suspect a small thermal fuse hidden under the yellow tape wrapping has failed. Those thermal fuses often fail from just "wear and tear" after several years, especially if there have been some power bumps over that time.
If primary is good, then it may be something else besides the transformer. Check the secondary voltages. If they are about right voltages, then there could be something wrong with the diodes to the right or the U3 device.
If primary is good but you have no secondary voltages, then you are more in trouble, as a replacement transformer will be difficult to find. Not impossible, just difficult or not worth the effort to repair...
Good luck.
 
It’s a correct reply to a previous post already closed but incorrectly responded
I interpret what you're saying is that the original thread is closed for new posts.
If that is the case, please provide a link to that thread. That way we can know what the original question was.
