Troubleshooting Your HVAC System’s Thermostat

A malfunctioning thermostat is a common reason for needing the help of an HVAC technician. Most consumers are unaware that anything is wrong with their furnace or air conditioner until a malfunctioning thermostat calls the problem to their attention.

The following are some easy tips you can use to quickly discover whether or not you have a malfunctioning thermostat:

Conduct A Battery Check

Batteries power the majority of thermostats sold today. Even though there are wires that connect the HVAC unit to the HVAC system, the thermostat itself still requires batteries. The wires running from the furnace or AC to the thermostat do not offer a power supply. After consulting the user’s manual, remove the front panel of the thermostat and replace its batteries.

Detecting A Brownout

An issue that is far less common than dead batteries is a power bottleneck or similar impediment. This type of problem can make it appear as if the thermostat is malfunctioning. Many refer to this circumstance as a brownout, and it can negatively affect the efficiency of your cooling and heating system. It occurs with any thermostat, even the newer models such as Wi-Fi thermostats. Before removing and replacing it, it is critical to ensure that the problem is not an overall power issue within the dwelling, but that it is an issue with the thermostat itself.

Double Check The Mode Of The Thermostat

In areas that experience all four seasons, it is commonplace for one member of the household to change the settings on a programmable thermostat and forget to tell the other individuals who reside in the home. For example, a resident of the house may have set the device to cool, leading others to believe there is a malfunction in the heating system. Checking the settings can save a considerable amount of time and trouble.


Determining Whether The System Is On Or Off

Checking to see if the system is on or off may at first seem like a simple tip, but it is a relatively common situation. If the thermostat displays the outdoor temperature, it is easy to overlook the fact that it is off. If your thermostat is one that is programmable, then you can program it. Another good suggestion is to follow a checklist when switching from heating to AC or vice versa.

Fan-Only Mode

Specific HVAC units feature a fan-only mode. Not surprisingly, this mode allows the system to run the fan only. For this reason, although the noise is similar, the system may just be blowing regular air, rather than conditioned air. This circumstance can make it seem as if the unit is not working correctly. However, it is an easy problem to solve, as you must switch the unit to the “auto,” instead of the “fan” setting.

Thermostat Setting Does Not Match Room Temperature

Dirt and dust can accumulate within a thermostat. Such debris can result in inaccurate readings, making it look as if the room’s temperature did not change according to the degree at which it is set. Keeping the thermostat clean solves this problem.

The simple suggestions listed above can help you troubleshoot thermostat issues when you are experiencing them. If there is a simple issue you can fix yourself, such as battery change, it is best not to spend money on a house call from a contractor.

Nevertheless, if you have been unable to solve your specific problem by following the above tips, contact an HVAC technician to evaluate it. Do not try to fix the problem yourself. You may inadvertently harm yourself, make the initial problem worse, or damage your home.
