Metal May Click as it Expands

• Underneath your stove's glass top is a network of metal parts. When you turn on your glass cooktop or the oven beneath, heat radiates through those metal parts. As each metal part heats up, it expands. The expanding metal in your glass stove may make a clicking sound. The clicking sound often starts a few minutes after you turn the burner or the main body of the stove on. Once the metal expands as much as it can, the clicking will stop on its own. There is no need to take any action.
  
  

The Oven Clicks as it Cycles On

• Check to see if your oven is turned on. The heating element in your glass stove's oven may be responsible for the clicking sound that you hear. Your glass stove's oven is designed to keep the interior at a set temperature. The heat source turns on with a click and continually heats the interior of the oven until it reaches the temperature set on the oven dial. But because the interior of the oven is not completely sealed, and the door is periodically opened, the temperature inside the oven drops over time. The drop in temperature signals the heat source to come back on with another click. The clicking will be more frequent on broilers and ovens set at a high temperature.
  
  

Keep Listening

• The clicking sound will eventually go away if your glass stove is operating properly. The metal expansion in your stove's interior is finite. Once the cold metal warms up, the clicking sound stops. In most ovens, this equilibrium is reached in a few minutes. If your oven or broiler is on, you may continue to hear periodic clicking as the heat source turns on to provide heat. To further troubleshoot the problem and make sure the clicking sound is related to the heating elements, turn the glass stove to the "Off" position. Wait five minutes. If the problem is the heating elements, the clicking sound will stop.
  
  

Call a Repairman

• If the burners and oven are switched off and there is still ticking, call a repairman. There may be a problem with a malfunctioning heating element, or there may be some other point of failure in the appliance. While you wait for repairs, unplug the glass stove from the wall, or shut off the circuit breaker responsible for supplying electricity to the unit. Do not continue to operate a malfunctioning glass stove.
