Hello, and welcome to JustAnswer. My name is ***** ***** I will be the one to assist you. You said your oven is out is it not coming on at all?

Customer: replied 6 months ago.
Comes on, but won't reach target temp. (350) It gets to 290 and holds.
Expert:  Webb-Guy replied 6 months ago.

and your getting a failure code for your bake element. Is it coming on at all?

Customer: replied 6 months ago.
it comes on. Voltage switches between 240V and 114V.
Checked - All elements good 15-20 ohms. All sensors check out - ~1100 ohms.
Customer: replied 6 months ago.
Actually, I replaced DLB, Bake, Broiler relays on PCB, I used to do some electronics for a living. But same results.

Hello Travis?
Customer: replied 6 months ago.
Are we stumped already? Do I still get charged for this?

Hello, Any feedback?
Customer: replied 6 months ago.
I responded "it comes on" that means the Bake Element. I put a meter on it. It switches between 240V and 114V. Is that normal?
Expert:  Webb-Guy replied 6 months ago.

sorry I am still here just looking into a few things for you.

Customer: replied 6 months ago.
Ah. Thanks. I'll hang on.
Expert:  Webb-Guy replied 6 months ago.

now what about the wiring itself

Customer: replied 6 months ago.
Voltage tested at the element connections. When I check the elements, I pull one contact off, and ohm out the element. Could they give a reading of, say 240 yet not be pushing the current through?
Customer: replied 6 months ago.
with the meter leads on the elements themselves, under voltage, is where I read 240V then when the controller switches, 114V. (Bake Element). Does that sound normal? It's what made me suspect the relays.
Expert:  Webb-Guy replied 6 months ago.

I would not think so but you have honestly replaced everything that could cause this.

Expert:  Webb-Guy replied 6 months ago.

you have already replaced the relays though right?

Customer: replied 6 months ago.
replaced those 3 relays. It switches between 240 and 114 as the controller clicks during heating.
Expert:  Webb-Guy replied 6 months ago.

I am still thinking that is the link to the problem.

Customer: replied 6 months ago.
you are thinking, no, it shouldn't go to 114V? I wonder if I'm seeing just some kinda residual voltage? It's a Fluke meter, they are sensitive. But it is a solid 113-114 volts, during that cycle. It always then switches back to the 240V, back and forth.
Customer: replied 6 months ago.
With no relays on, no voltage. Nice clean OFF. Wondering how it could give 114, as if the neutral was getting into the act.
Expert:  Webb-Guy replied 6 months ago.

I am not certain I will open this up to see if anything else has any other ideas.

Customer: replied 6 months ago.
Have to go but please post what you think I should try.,
