If you feel it's not working, try these steps: To check your furnace, make sure the switch is set to “HEAT,” and turn the temperature setting up to 80 degrees. Give it five minutes to see if the heat kicks on, and if so, adjust it to your preferred setting.
If your thermostat is registering incorrect temperatures, then it may be time for a replacement. You can test your thermostat's reading by using a portable indoor thermometer to verify the temperature is correct. The sensor in your thermostat can malfunction from old age, misuse, or manufacturing defect.
Pull the thermostat off the wall and jumper the red and green wire. If it turns on, thermostat is bad. If it doesn't, something else is going on.
You may need a clean air filter, there may be a refrigerant leak, or the fan may have malfunctioned. An HVAC technician can determine the exact nature of the problem and make replacements or repairs.
This can occur when there are blockages or restrictions in the air ducts, preventing the cool air from reaching your home. Common causes of airflow problems include dirty air filters, blocked vents, and debris in the air ducts.
Check the Power Source: Ensure your thermostat is receiving power. Replace batteries if your model requires them or check the circuit breaker if it's hardwired. Inspect the Wiring: Over time, wiring can degrade. Inspect for any loose connections or signs of wear.
If your thermostat has fresh batteries but suddenly lacks power, flashes, or isn't responsive to adjustments, it may need replacement. If resetting the thermostat doesn't resolve the problem, you may have wiring problems or faulty components causing your thermostat to not turn on.
The main function of your thermostat is keeping the home at the correct temperature. One way to ensure this is to attach a thermometer on the wall near the thermostat. If the room temperature on it does not match the temperature displaying, you have an issue.
The average lifespan of a Honeywell thermostat is typically around 10-20 years, depending on various factors such as usage, maintenance, and environmental conditions. With proper care and regular servicing, a Honeywell thermostat can last even longer.
Access the Menu: Tap the menu icon on the thermostat's touch screen. Hold Down the Weather Button: Press and hold the weather button for five seconds. This will bring up the reset menu. Select Reset Option: Navigate through the options until you find “Factory Reset.” Tap on it to select it.
Signs that You Need to Replace Your Thermostat
Your HVAC system keeps cycling on and off irregularly. Registering wrong temperatures. High energy bills. Inconsistent temperatures through the house.
Some of the most common thermostat issues include:
The thermostat is broken, not properly level, or dusty. The thermostat needs to be recalibrated. There is loose wiring causing a thermostat issue.
Turn on the heat on the thermostat and increase the temperature. You should hear a sound from both the thermostat and the furnace, and whichever doesn't make a sound has a problem.
To further help, many Honeywell Home T-Series thermostats are mounted on a Universal Wall Plate that allows you to change models by simply 'popping' one in place of the other.
The Lifespan of a Thermostat
On average, most thermostats last about 10 years, depending on the model, usage, and proper maintenance. However, many people decide to replace their unit sooner to take advantage of new energy-saving technologies.
When the thermostat requests cooling, the outdoor compressor should be running. If your compressor is running, but the air is not blowing through the indoor vents, you may have an issue with the indoor HVAC unit's fan.
If the thermostat clicks but the AC or furnace doesn't turn on, most often it's because the filter is clogged. A blocked filter will restrict airflow. The particles it's designed to trap eventually clog the filter media, and the system will be unable to generate heat or cool air.
