How to Detect a Faulty Thermostat

The thermostat for your HVAC system is an imperative component of how it operates. The thermostat allows you, as a homeowner, to set a particular temperature for your home to be. Your HVAC system will automatically run until it reaches the desired temperature that you set. However, just as with any sort of electrical system, thermostats can go bad. Understanding the issues you may face and how to fix them is essential to ensuring that your HVAC system gets back to working properly as quickly as possible.
Continually Running HVAC System
Your HVAC system is programmed to run until it reaches the temperature that is set on your thermostat. For example, you may set your thermostat at 70 degrees in the summertime. If the thermostat measures the temperature inside your home at 72 degrees, it will turn on the air conditioning part of your HVAC system to cool the temperature. Once the inside thermostat reads 70 degrees, it will turn the HVAC system off. However, if your HVAC system continually runs, it's an indication that you have a problem. Start by checking to see what the set temperature is on your thermostat. Sometimes, you may accidentally set the temperature way too low. If this isn't the issue, then it's likely that you have faulty wiring between your thermostat in your HVAC system. It's advisable to call in an expert at this point to handle the situation.
Your Thermostat Is Not Working
If you've walked over to your thermostat and noticed the display is off, it can be one of two main issues. The most common is that the batteries are dead in your thermostat. Most new thermostats will have an indicator light that will blink when your battery is getting low. Start by switching out the batteries in your thermostat and see if that remedies the problem. If you still have no screen display after switching out the batteries, it's time to head down to your electrical panel box in the basement. Check to see if the circuit breaker is tripped for the HVAC system. If so, turn the circuit breaker off and back on again. Give it a couple of seconds and see if the breaker trips again or not.
Room Temperature Doesn't Match The Set Temperature
If you notice that the temperature inside of your home doesn't seem to be anywhere near the desired temperature that you set on your thermostat, you want to listen to see if your HVAC system is operating. In the event that it's not operating, it's likely that there's an issue with your thermostat. It's best to call in an expert to determine if the problem is in the wiring or thermostat itself.
