Zone Heater Driver Error
I'm getting a Thermal Shutdown Zone Heater Driver fault on a 6890N after replacing the mainboard. the mainboard came directly out of a working 6890N with no issues.
I cannot find any information on this fault. Does anyone have any ideas?
Thanks

Thanks for your response Dan. I found this in the manual but nowhere else and no comments.
Fault 293: Zone heater driver. Zone heater driver Not ready: Zone heater driver
LIke I stated in my last message, this main board came out of a 100% working 6890N. So I know the mainboard was good. All heaters and sensors ohm out perfect including the oven shroud. All were checked prior to putting the new mainboard into the 6890N. Unless there is a problem with the AC board (doubtful) or the torrid transformer secondary, i'm just not sure what if anything would have taken out the new mainboard.
Thanks for your help.

The original issue was the GC was operational and running then the display went out and all lights went on. I've seen this before and it was mainboard. Swapped the mainboard with a known good one and here we are. Very strange.
Thanks fo ryour help.
