Got Thermostat Problems? Troubleshoot the Issue With These Steps

Problems with the thermostat in your Fort Collins home can cause your HVAC system to stop working completely, or cause it to heat or cool ineffectively. Here are a few tips that can help you solve some of the most common thermostat problems and help you save on the cost of a service visit and repair.

HVAC System Won’t Start

When the HVAC system won’t run and there seems to be no power at the thermostat, try resetting the breakers for the system or replacing the batteries in the thermostat¬†if it requires them.

If the system still won’t start, turn off the power and carefully remove the thermostat’s cover. Check for loose or dirty connections, and tighten or clean them if necessary. Also check for excessive accumulations of dust, pet hair, nicotine or other substances that could interfere with the mechanical contacts or electronic sensors. Use a soft brush or a rag to clean the inside and any external vents.

System Turns On and Off Frequently or Won’t Shut Down

If your HVAC system is cycling frequently or won’t turn off, make sure both the inside and outside of the thermostat are clean and free of debris. Use a level to make sure the thermostat is perfectly level and plumb. Mechanical models with mercury switches can malfunction if they aren’t mounted properly.

Finally, try adjusting the anticipator switch, which is a metal tab mounted on a circular scale. It’s used to determine how quickly the thermostat reacts to changing temperatures. Mark its current setting, adjust it, and wait a few hours before making any further adjustments.

Temperature Doesn’t Match Thermostat Setting

If the temperature in your home doesn’t match what the thermostat is set for, check to make sure the thermostat is clean and mounted correctly. Adjust the anticipator if necessary. Finally, make sure that the thermostat isn’t located in a drafty or sunny location, which could cause it to sense the temperature improperly.
