What is the temperature sensor & why would it need to be replaced?

The oven temperature sensor monitors the temperature inside the oven cavity and relays that information to the main control board. This helps the oven maintain the correct and consistent temperature needed for cooking or baking.

When the oven temperature sensor assembly shorts or burns out, it can cause the oven to malfunction and lead to inaccurate temperature readings or a failure to heat up. The sensor assembly may fail due to regular use over time or resistance changes due to debris or mineral deposits.

Symptoms of a bad temperature sensor include:

  • The oven won’t reach or maintain set cooking temperatures
  • An error code related to temperature regulation that appears on the oven display
  • Damage to the sensor such as cracks or shorts

Keep safety first

When working on any appliance, always keep safety first to avoid personal injury or damage to the appliance or parts. Here are some safety tips to keep in mind:

  • Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by preventing any risk of electric shock.
  • If the appliance has recently been used, give it plenty of time to cool down before working on it.
  • Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
  • Work in a well-lit area so you can clearly see and access appliance parts.
  • Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
  • Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
  • Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
  • Wear insulated work gloves to protect your hands from sharp metal parts and debris.
