Yes, thermostats do need to be cleaned regularly to ensure proper functioning and accurate temperature readings. Over time, dust, dirt, and debris can accumulate on the thermostat's surface and inside its components, leading to inaccurate temperature readings and reduced efficiency. Cleaning the thermostat involves gently wiping the surface with a soft cloth and using compressed air to remove any debris from the inside. It is important to turn off the power before cleaning and avoid using any liquid cleaners.
