Product review (1 stars): Started Fire During Cleaning
With the knobs removed, an aerosol cleaning solution was sprayed on the glass cooktop.  Under the knobs are electric switches used enabling the light-sparking of the burners and the switches are not liquid tight.  These switches ignited the cleaner solution causing a large flame to burst over the entire surface of the cooktop.  Essentially a small explosion.  Contacting customer relations with an obvious safety flaw, they only offered to pay half of the labor and parts to repair the melted switch.  Pictures of the faulty part were sent to GE showing how the seal of the switch failed igniting the cleaner.  They responded with sorry, but we will help you no more.  Your case has been closed. I opened a case with the US consumer safety department and hope to see something done about GE's unresponsiveness.  I realize the spray of the cleaner perhaps wasn't the best choice, but the knobs are on the top and can be removed to help with the cleaning process.  Cleaning solutions are highly likely to touch those components.  A neighbor of mine who owns the same unit spilled water on the surface which shorted out the switch.  The repair service person stated he fixes a couple of them a year, which runs around $250 on top of the service call.  Other than the switch, the unit does work well, but their response and how they handled an obvious safety flaw lost them a GE customer.  Profile and Monogram appliances throughout my entire home.  None of them will be replaced with GE products.
