HELP! The oven was working just fine and then stopped turning on. Threw an F30 error. Then it suddenly started working again. This happened a couple of times. Possibly connected to something with the door as it seemed to work after door had been opened and closed and one of the times it was buzzing unless the door was left propped open. Parts store (Cashwell Appliance Parts) suggested it might be the door lock. Replaced that, problem still existed.

Replaced the oven temperature probe, problem still there. Replaced the ECU and the new one would not power up. Swapped out the new one for another one, still wouldn't power up. Put the old one back and now it won't power up either.

The old ECU did power back up after the first swap out, but not the second one. The eyes on the stove work, just not the oven, and now not the display.

Is it the wiring harness? Is there a fuse or relay somewhere? Cannot figure out what is wrong with this stove!

You will need a multimeter to check voltage coming into the clock oven control board. On the clock oven control board put your meter probes on L1 and L2-IN and see if you get 240 volts.

Here's the clock oven control board for your model:

If the multimeter does not show 240, it's a plug or fuse issue? Someone told me if the eyes worked, it was not the power.

If your not getting 240 volts on L1 and L2-IN then you have a voltage/breaker problem going to the range.

Did you do a voltage test at the terminal block where your power cord connects to?

You'll need to pull the range out from the wall, then unplug it from the wall outlet, then and look for any burnt wire connections after you remove the back access panel to your range. Also you will need a multimeter to check the voltage to the range at the terminal block.

Here's the terminal block for your model below, its where the power cord connects to your range. Use the multimeter to check for 120 volts from the CENTER(Neutral) to the LEFT(Hot), and CENTER to the RIGHT(Hot) should also be 120 volts.

Then put your meter leads on the LEFT and RIGHT terminals on the terminal block and you should have 240 volts.

Here's the terminal block for your model:
Terminal Block 5304409888
