Furnace thermostat error making a clicking noise

What Causes a Furnace Thermostat to Make a Clicking Noise?

Sound from the furnace: Normal sound from the functioning of the furnace. Make sure it is in an appropriate location, that the filter and ductwork are clear, and the noise is consistent.

A running appliance: When things are plugged in they can make noise. Try unplugging all appliances and checking if the clicking stops. If it does stop then you know what source of sound it was that’s making the noise.

Light switches: Certain types of light switches will switch on and off when they’re turned on and off because they create electricity to power light fixtures as well as other electrical devices nearby. Check this option first to rule out unnecessary visits by a technician when all you need is to fix your light switch.

Besides this error code, other frequently reported heating-related problems include no heat, irregular temperatures, and refrigerant leaks. Preventative measures include: checking filters monthly, keeping vents clear of debris, not blocking air intakes or vents with furniture or clothing, and having ducts professionally cleaned every 5 to 10 years.
