Lower oven broiler element not coming on.
I checked the broiler element for resistance, I read 18 Ohms.
I checked the incoming voltage, I get 120v to ground on one wire. 0 V on the other wire to ground.
I checked the heat sensor resistance I get 1080 Ohms.
I checked if power was being passed through relay K2 and it was not but after other trouble shooting and some power cycles then I saw power being passed through k2.
I then checked the leads to the broiler element again and both showed 120v to ground. So I figured the element was bad after all. Ordered and replaced the element but had same results and all tests show I am back to 120 on one lead and 0 on the other.
If I set to bake mode the oven starts to heat up using the lower element the broil element does not come on.

Any thoughts. I am about to pull the unit out from the wall again to test to see if I am getting power from k2 relay but I also don’t know how to tell if the relay is being told to turn on.
So k2 relay bad or controller problem.

Thank you,

Hi,

You need to test across the broil element terminals, not each to ground.

Put one meter probe on the broil element terminal and the other meter probe on the other broil element terminal and you should get 240 volts.

The problem is the relay board:
Board 316570520

Thank you.
I believe I had 120V when I measured across the broiler terminals.

Ok, that still indicates you need the new relay board to fix it.

Make sure you disconnect power to the oven first!

Same oven, continued.
Relay boards became obsolete with no build date in the future so further troubleshooting led me to the relay for the broiler element was not always making contact. I was able to buy the relay on Amazon for about $14, replaced and everything was good.

However, same unit now. Problem.

Set Preheat temp, will come up to Preheat and then not keep heating, baking. The display still shows the preheat set point but it is not up to that temp. If you cancel and restart it starts preheating again, and shows that you have lost temp.

Any thoughts would be welcome.

I will check the availability of a new relay board to see if by chance it came back into availability.

Thanks and Merry Christmas.

Merry Christmas!

It must need that relay board then, that's all I can think of as this problem.
