Air Conditioning Thermostat Calibration

My thermostat isn't working, what should I do? Before you throw in the towel to call your local technician, here are a few things you should look into before doing so:

1. Is your thermostat receiving power?

if it is shutting on and off or if the backlight isn't working properly, you'll want to check if the thermostat is receiving adequate power. Thermostat receive power from the batteries and system, ensure you are getting power from both. Check to see whether or not a circuit has tripped. Once determined that everything is fine with your circuits, replace the batteries with a fresh set.

2. Is your thermostat mounted properly on the wall?

If your thermostat is giving faulty readings, check to see if it's properly mounted. Use a bubble level to check to see whether or not it is placed correctly.

3. Is your thermostat near any source of hot or cool air?

It won't get a proper reading of the room temperature if there are sources of cool or hot air nearby. Keep the thermostat away from vents, windows and direct sunlight as the cool air or heat can influence the numbers to fluctuate.

4. Is your thermostat dirty?

Make sure the thermostat is clean so there is nothing that factors it into giving inaccurate readings. With dust buildup, it can keep the temperature slightly cooler than normal.
