How to Fix Weber Genesis Thermometer Which Is Not Working

Let’s explore some simple solutions to fix a Weber Genesis thermometer that is not working.

Calibrating The Thermometer

Calibrating the thermometer is a basic solution to fix inaccuracies in temperature readings.

Here’s how you can do it:

  1. Fill a glass with ice and add water until the glass is full.
  2. Insert the thermometer probe into the glass, making sure it is submerged in the ice water.
  3. Wait for a few minutes until the reading stabilizes.
  4. If the thermometer doesn’t read 32°F (0°C), use a small wrench or pliers to adjust the nut located behind the dial until it aligns with the correct temperature.
  5. Test the thermometer’s accuracy by checking the reading at boiling point (212°F or 100°C). Adjust if necessary.

Replacing The Thermometer

If calibrating the thermometer doesn’t resolve the issue, it might be time to replace it. Follow these steps to replace the thermometer on your Weber Genesis grill:

  1. Make sure the grill is cool and no longer in use.
  2. Locate the thermometer on the grill lid.
  3. Depending on the model, you may need to unscrew the bezel or remove any screws holding the thermometer in place.
  4. Gently pull out the old thermometer, being careful not to damage any attached wires.
  5. Insert the new thermometer into the hole, aligning it properly.
  6. Secure the bezel or screws back into place.

Protecting The Thermometer From Environmental Factors

Prevention is always better than cure. Here’s how you can protect your Weber Genesis thermometer from environmental factors:

  • Keep your grill covered with a high-quality weather-resistant cover when not in use to protect it from rain, snow, and extreme temperatures.
  • Avoid placing your grill in direct sunlight as excessive exposure to UV rays can damage the thermometer.
  • Regularly clean the thermometer to remove any built-up grease or residue that can affect its accuracy.
  • Consider using a grill thermometer cap or shield to provide additional protection, especially during heavy rain or windy conditions.

By following these solutions and taking preventive measures, you can ensure that your Weber Genesis thermometer functions properly and provides accurate temperature readings, allowing you to enjoy perfectly cooked meals every time you fire up your grill.

Prevention Tips To Maintain A Functional Weber Genesis Thermometer

Prevention is always better than cure, and this holds true when it comes to maintaining a functional Weber Genesis thermometer.
