I have a GE Profile wall oven, MW on top, oven on bottom. It is 1.5 years old and haven't baked in it more than 12 times. The display panel shows "Communications Error with Lower Oven" when bake is selected on control panel.
Under warranty GE replaced a control board on the MW, worked for two times then error occurred again out of warranty about 6 mos later. Had a different repair company out and they replaced the touch panel first, without change, then replaced the oven control board and oven harness. Worked for 1 bake cycle and failed again after ~ 3weeks. GE is absolutely no help. Anyone seen this problem before or have any ideas?
