I have 1 1/2 yr old refrig that has control panel problems - beeping and display's jumping around constantly. It will go from turbo cool to showing temperature that counts down from 46? to 32 and then jump randomly to another lighted display....not necessarily in any particular order. Just always moving randomly and beeping....The refrig seems to still be operating fine but none of the pushbuttons work either, cannot check or set temp, cannot switch from water to ice, etc....Suggestions? A new main board does not solve the issue. Thanks, Jeff
