Surface Not Turning On

  • On a coil type burner, remove the coil unit, check the contacts for continuity, examine for pitting or carbon build up which can prevent good contact. If no continuity, replace coil unit. If pitting or carbon is present, clean and smooth contacts, and replace receptacle.

  • If coil unit checks ok, replace control switch.

  • On smooth top units, check the switch first. With the appliance unplugged or the breaker turned off, refer to the wiring diagram, and check the switch contacts for make and break. When performing this check always remove at least one wire from the circuit being tested to prevent getting a false back reading. Replace switch if any failures are found. If the doe’s not sealswitch checks ok, check the wire pairs for continuity. Any failure here requires the burner unit to be replaced. Burner replacement will require the top being removed, and with some units, recalibration will be necessary. Follow the instructions that come with the new part.
  • Indicator lights that don’t come on or won’t turn off, are checked in a like manner. Hot indicator lights are controlled by a sensor mounted in the burner unit; some are available separately and some require the burner assembly to be replaced as a unit.

Oven Bake/Broil Failure


  • Remove the non-functioning element from its mounting, remove the wire from one side and check the element for continuity; replace if necessary. If the element is good, reattach the removed wire and remount the element. If the oven has analog controls, it will have a bulb and capillary thermostat. Check it for continuity across the terminals; replace if necessary.

  • Some Analog controlled ovens have a separate selector switch. This switch also needs to be checked for proper operation. If a time bake option is present, check that both the time-on and time-off selectors are set to the current time on the clock. If either knob is pushed in, the oven will not come on.
  • On electronically controlled ovens, there will be a sensor instead of the bulb and capillary thermostat. To check the sensor, disconnect it at the outside rear of the unit, and read the resistance (ohms) of the sensor with a multi meter. It should read approximately 1000 – 1200 ohms at room temperature. If the sensor is good, and the element is good, you will need to replace the electronic control.
  • On built in ovens, where everything appears to be working, but neither element gets hot, there is a good chance the thermal protector has blown. This is a non resettable device that looks like a dryer thermostat and is located usually on the back or top of the oven cabinet. The oven will have to be pulled from its installed location to access the thermal protector.

  • Single ovens can usually be removed by one person of strength, if the oven door is removed first. Consult your owner’s manual for oven door removal. There will be screws attaching the oven to the surrounding cabinet; some of these are concealed by trim pieces that will have to be removed first. Have a pad on the floor in front of the installed oven (the removed oven should be placed on this pad, which will protect the floor and make the oven easier to move).

  • Remove the back overlaying panel from the oven and you should see a circular, quarter size device with two wires going to it (one wire coming from the control panel and other going to both elements.

  • Remove one wire from the thermal protector and check continuity across the terminals of the thermal protector. Replace if necessary, making sure to maintain the specifications of the device. Replace the removed panel to the back of the oven. It is prudent to inspect all the wires and connectors before putting the panel back on. You can repower the oven briefly in order to try it out before reinstalling;
  • CAUTION STAY WELL CLEAR OF ANY EXPOSED WIRING AND CONNECTIONS! HIGH VOLTAGE IS PRESENT AND IMPROPER CONTACT RESULT IN ELECTROCUTION, INJURY, OR DEATH!. The door does not have to be on, but if you get a “door open” error; hold your finger on the light switch button. When you have determined that the oven is now operating, remove power once again and reinstall the oven, and replace the screws, trim, and oven door.
