Hi! First time posting so go easy on me
I have an eight year old Samsung model number NE595R1ABSR that is not holding temperature. I can heat the oven to 350 degrees and restart the temperature five minutes later and it’s down to 310. Now this is a split oven so there’s a shelf in the middle that you can put in or take out for two different temperature zones. At first I replaced the upper thermostat to see if that would fix the issue. Didn’t work. The other convection motor wasn’t working either so I replaced that to see if it would make a difference. No it did not. So I tested the thermostats and the burners with a DMM. The upper thermostat read 1167 ohms. Lower thermostat was 1181. Upper burner was 15.7 and the lower was 19.7. Which all seems fine, although the lower burner is supposed to be between 26-30 ohms according to the technicians manual.
I’m thinking none of these things are my issue. The only thing left that I can think of is the main board, but I don’t want to purchase without some second opinions. Thanks in advance for your time!

Hi,

Yes, you are correct, Its the main control board with the relay's on it that is the culprit.

Here it is for your model:

Right on thanks, Jake! And do you think the lower burner is an issue having tested slightly lower ohms than what it should with the DMM?

I've never seen where one oven element would be a different ohm rating than another oven element. Are you sure you read that right? Can you upload the manual so I can see it too?
