Maytag (Jenn-Air) Electric Oven electrical problem

[gus]

Hi:
I have my Maytag electric oven which is not working. The relay board is not supplying power to the control board. I think the problem is the transformer is the Relay Board. I would like to check the transformer but I don't know the internal arrangement. Does someone have this?
Does someone know if it's possible to buy a replacement for this transformer?

Thanks Gus

Let's back it up a step...

Are you not getting a display even though you can progam the touch pad, or is the front panel completely dead?

Hi:
The front panel is totally death. There is a 4 pin connector (J1) that I assume provides power to the control board. There is no voltage at these pins. The transformer has 120V at its inputs, but I can't measure voltage at the transformer's outputs (the pins connected to the diodes and Capacitor).
That's why I assume the transformer is not ok.
I red in some place that this transformer would have an internal fuse. Is that correct?
There is about 110ohms between pins 1 and 6 (I assume it's a primary). But between pins 2 and 3, there is an open circuit.

Thanks;
Gus

The relay board must be replaced. I agree after you related your findings that the transformer is bad. Unless you were not looking for DC voltage.
The secondary voltage is 12v DC by the way.


There's a little more to diagnosing the unit, as I mentioned earlier. Here's some quick synopsis:

At the end of the day, you might find yourself replacing the entire glass touch panel along with the clock and relay board....it won't be the first time.

Ok. I replaced the transformer internal fuse with an external one, and then the oven started working.
However, after some seconds, it started showing the F1 error code. Any idea?

Thanks for your support!
