After a log wait LG LCE3010 cooktop was delivered on October 4 th.  Eversince it was delivered Power On/Off button has been tempramental.  Sometimes once touched it's on.  Sometimes it does not come on, sometimes once press hard, it comes on etc.  When it does not come on, circuit  breaker has to be turned off and on to get it back on.  Electrician checked it thoroughly and power is coming up to junction box that feeds the cooktop.  This has been a very frustrating experience.  i built a new kitchen.  LG oven and microwave are still backorderd.  Without a functioning cooktop, kitchen is not functional.
