What is a Honeywell Thermostat Faulty Sensor?

A Honeywell thermostat faulty sensor means that there’s an issue with the temperature sensor located inside the thermostat. This can result in the thermostat not working properly or displaying inaccurate temperature readings, which can make it difficult to maintain a comfortable temperature in your home.

How to Troubleshoot a Honeywell Thermostat Faulty Sensor

Here are the steps to troubleshoot a faulty sensor:

Step 1: Check the Sensor Location

The sensor may not be reading temperature properly because it is located in a spot that is exposed to direct sunlight, drafts or heat sources like lamps or fireplace. Check if the sensor is located in the right place. It should be installed on an interior wall, away from direct sunlight or drafts.
