Problems with My Comfort System: Is the Thermostat Broken?

Digital-Thermostat-HandWhen you change the settings on the thermostat, it can take a minute or two before you hear the fan set in. The fan is delayed for a moment due to safety settings that ensure the heating/AC equipment works properly before air moves into your home. But if, after a couple of minutes, you hear nothing coming from the vents, should you be worried?

Many people assume the thermostat is responsible when there is a problem with the heating and air conditioning systems. This may be the case, but it’s likely you’ll need to call in a technician to resolve a larger problem with your HVAC equipment. Learn more about thermostats and common problems with a heating and air conditioning system from the guide below.

Things that Could Go Wrong with a Thermostat

There are a few different things that may go wrong with a thermostat, even though the problem often turns out to be a larger electro-mechanical issue. Of course, you don’t want to call in a technician unnecessarily. Here are some reasons technicians get called in even though the issue could easily be resolved.

  • Someone has switched the thermostat off or set it incorrectly. Check to be sure it has not accidentally switched into “heating” mode when you want cooling, or vice versa.
  • The thermostat is in “fan on” or “fan only” mode. This will not cool or heat a home, and will only move air around.
  • Your thermostat needs batteries. If the screen is completely blank, try changing the batteries.

Other Troubleshooting Options

So you’ve ruled out many common thermostat problems. You can try a few more things if you want to avoid calling in a technician. The issue could involve a fairly simple fix.

  • The issue could be electrical. Reset the circuit breaker if the heater will not start up at all, or if there is no display on your thermostat.
  • You can try changing the filter for a system that will not perform properly. This is often the reason for low airflow, off temperatures, or even a system that short cycles.
  • When using a gas furnace or boiler, check with your gas company to make sure there isn’t a problem with your service.

You Likely Need a Technicians

The fact is that your thermostat is only a tiny part of a whole system. It contains a sensor, which could fail and cause your heating/AC troubles. And it is possible that you only need to replace the thermostat. However, there are so many other components of your HVAC system, that it’s quite likely one of these is at fault.

Faulty wiring, bad contactors, dirt in the coils, a broken fan motor, problems with the ignition switch—any of these could cause a major problem with your AC or heating systems. Call in technicians to get started on repairs ASAP, so that you can get back to comfort sooner.
