GE Monogram ZISP480DTASS Temp control not responding

[Sinister310]

Guys I need help,

                      I woke up and the freezer was warm and the fridge was as well, I'm on my 3rd inverter in 15 years. I have a lot of power outages in my area and I believe the power spikes are to blame. I checked some videos on youtube and saw that I could perform a diagnostic test, I did that and now my temp controls are locked and I can't restore it. Ive tried to reset it using the breaker power off method, I let it sit for 12hrs powered down and nothing seems to work. The actual control lock button is not engaged. Nothing seems to work. Video of Control Panel Malfunction

Same issue here on a GE Monogram ZISB480 DMC. Tried to enter Diagnostic Mode and now the control is locked. Temperature LEDS are solid, though indicating wrong temperatures when checked with a thermometer. Pushing ANY of the display keypads sounds 3 beeps. Unplugging does nothing. Has anyone figured this one out yet? Thank you.

Once I changed the main control board my control panel issue was solved...

To all those looking for an answer, and to Sinister310 (thanks) - replaced the main board (with WR55X10942)  today ($135) and just like that, the temperature controls returned to normal functioning. The board had a bad relay evidenced by a burnt pin on the underside of the relay. Replacement took about 15 minutes. FYI, although the connectors match up, the jumper callouts are different.

Glad to hear you fixed it... it was a pain in the butt....
