Your HVAC system thermostat isn’t working and you heard that it might be broken. You may start wondering how your thermostat got broken. And what should you do next to fix it? Or your first step to provide self hvac service as whole by starting to look in to your thermostat. 
Here we are listing common causes of a broken thermostat, together with some solutions.

1. Your Thermostat Isn’t Getting Power

In this first case, your thermostat might not be getting the electrical power supply to function properly for one of the reasons below:
Time to change the batteries. If your thermostat is battery powered, batteries could be low or dead and it starts causing trouble. Always keep an extra set on hand to replace when you find this first sign of trouble. 
The breaker has tripped. If thermostat is hardwired, check the breaker box for a trip. Wires connected to the breaker may be loose, even if everything looks normal, flip the thermostat’s breaker on and off just to be sure. You’ll be pleasantly surprised if this solves the problem. If the thermostat does not respond, or the breaker re-trips repeatedly, the breaker itself may be bad and needs replaced. This is a relatively inexpensive fix.
The wiring has gone bad. Over time, the thermostat wiring becomes loose, worn, damaged, or corroded and all these star causing thermostat malfunction. In this case, you may need an HVAC professional to fix this. 

2. Your Thermostat Interior Needs Cleaning

There are some issues which simply a matter of cleaning and you can do yourself when there are any issues with your thermostat, simply remove dust, hair, and debris is dangerous to any electronic appliance 
First, turn off the power. Open the cover. Gently remove dirt and debris with a soft brush or compressed air. Replace the cover and reconnect the power.

3. Your Thermostat Anticipator Needs Adjustment

Do you still have an analog thermostat? If yes, you may need to do some anticipator adjustment.

However, this adjustment could make your thermostat run for a short term, but remember to mention this problem when you have an HVAC professional at your door step for maintenance.
