Brand:GE Model Number:CTS70DP2N2S1 Main Symptom: Stuck in a boot loop What happens & when: The oven lcd was dead and I noticed it was just a white backlight. I took the front panel off and noticed it was rebooting itself from the lights in the back. I ended up replacing the control module. Now the GE loading screen comes on and then the wallpaper comes up for a second and goes blank. After a few seconds it just gives non stop tones. The part I replaced had the exact same part numbers and revision dates. The part number was WB27X35131. I noticed GE only sells the entire front LCD panel WB56X40093 for this which from what I can tell is just this control module, LCD, and another board that I can’t find any info on at all. If anyone has any info that would I would appreciate it. I attached a video of what the oven is doing and the tones at the end of the video.
That other board you are talking about is called the 2-key UI board on the wiring diagram. It can fail and cause issues as there are error codes related to it, but other than that the manufacturer doesn’t really give much info on it. The manufacturer does not list it as individually serviceable on this model, only as part of WB56X40093. The other possibility is the main control board WB27X43208 isn’t syncing up with the new control board WB27X35131 that was installed.
That WB27X43208 board isn’t too bad price wise would you recommend I replace it and give it a shot? The 2-key UI board isn’t available separately as you stated. Is there anything that would need to be synced when you replace these boards or are they fairly plug and play?
I’m not seeing anything about programming or syncing them to each other, but the tech sheet for this model mentions a heartbeat LED on the boards that might tell you which is the problem. It does mention the 2-key UI board. I’m attaching the entire tech sheet as well.
I really appreciate the tech sheet I will read through that. The WB27X35131 board I replaced the light is flashing faster than I would say 1 hz. The UI board and main board are what looks to be a 1hz rate. I might have to have a service tech come out and check to see if they are able to get any fault codes before I just waste money on parts. https://www.youtube.com/shorts/yJvg1vp-u60
