Brand: Samsung Model Number: NE59M6850SS/AA Main Symptom: Lower Heating Element has no voltage What happens & when: When activating the lower oven or as a single oven, the bottom element does not turn on. No Voltage is observed at the element terminals
Error Code (if any): C-f2
Parts or tests already tried: Replaced User Interface Board DE92-03959E and Main Control Board DE92-03960L

I have not been successful at figuring out why the lower oven on my stove will not heat. I tested the 2 oven temperature sensors by checking continuity and resistance values. I tested continuity on the Range High Limit Thermostat. I tested continuity and resistance on the lower element and it is fine. I even wired the lower element using the upper element wiring and was able to get the lower element to heat the lower oven. I test voltage at the wires leading to the lower element and the voltage is always 0 VAC. All other parts of the stove are working. I checked error codes and I see “C-f2” in the list of 5 latest error codes. This may have been from me unplugging the user interface control board during trouble shooting. See below.
I suspected it was the main control board DE92-03960L that was bad. I bought a replacement main board and when I replaced it, the oven continuously cycles as if it was powering up and down every few seconds (it keeps playing the little jingle in the beginning). I cannot activate the oven because it keeps cycling.
I then suspected that the user interface board DE92-03959E was also bad. I replaced that board and the oven still cycles continuously with the new main control board DE92-03960L. I then put the old main control board back in and I have the same problem with the lower element not receiving voltage.
It is possible that the new main control board is faulty. Any help determining before I keep buying new parts? Can someone walk me though testing the main control board? Also is it possible for the user interface that plugs into the user interface board to cause a problem? It does seem like the plastic that goes over the display is distorted a little from heat. Thank you.
Check at the main control board from the bake relay to the broil relay to see if there 240 Vac. If there is power but no power at the element then there is a wiring issue that will need to be corrected. If there is not voltage but voltage into the relays then this will be a board issue.
I think that I should see 240VAC if the Bake Relay was working. Is that correct?
Further, if I put one lead from my meter on the yellow wire and the other lead to the oven chassis, then turn on the lower oven to Bake. I see 120VAC. If I put one lead from my meter on the red wire from the white top white connector (as shown above) and the other lead on the oven chassis, then turn the lower oven to Bake, I see 120VAC. When I cycle the oven off, the voltage goes to 0VAC. Does that mean that the relay is working? If so, why would am I not getting 240VAC at the lower element?
I am still at a loss as to why I do not get voltage to the lower element. I am also unsure why the replacement board I have will continuously cycle. Has this happened to anyone? Could the new replacement board be faulty?
According to the troubleshooting explained above, the board is not sending voltage to the terminals for the Bake heating element. I purchased a new board, however the new board makes the oven continuously cycle on and off. The short chime that happens when you plug the stove into the wall outlet will continuously play every 4 to 5 seconds. I cannot select any of the oven functions either because it seems like the oven is continuously re-cycling power. Any ideas what might cause this? Is the new board malfunctioning?
I suppose I should ask the question differently. Is the oven continuously cycling power with the welcome chime continuously playing every 4 to 5 seconds a known symptom? I am always skeptical that a brand new part can be delivered damaged. Any insight as to what might cause this. I have another board coming as the new board is being replaced under warranty. Thank you.
Try the board that you are getting because it could have been faulty but also recheck all wiring to make sure that nothing was miswired and no damage to the wiring or connectors.
