Is My Thermostat Causing Problems with My Heating System?

It’s good to keep your thermostat in mind whenever you have issues with your furnace, heat pump, or boiler. No matter what type of heater you have, if the thermostat won’t work, the heater won’t work.

How Your Thermostat May be Causing Problems

The most frequent difficulty that heating specialists see with thermostats is a miscalibration in the heat sensor. Modern thermostats use a device called a thermistor to gauge heat; a thermistor registers electrical resistance that increases with the ambient heat, which a processor then translates into data for the system to read. A fault in the thermistor will make it sense incorrect temperatures, and it will start turning your heater on and off at the wrong times, leading to uneven heating or too much heating. Sometimes, the miscalibration will cause the heater not to turn on at all. Technicians can easily recalibrate the thermostat.

Electrical trouble can also plague thermostats. Most thermostats are connected to the heating system using five different wires, which control turning the heater and the fans on and off. Crossed and broken wires can cause the thermostat to lose its connection to the heater, or cause the heater and the fans to run continuously. Repair technicians with knowledge of thermostat wiring will need to fix this problem.

If you have an older manual thermostat, or even a standard digital model, you should consider upgrading to a programmable or wireless model. Even if the old thermostat isn’t creating “problems” for your heater, it is probably making it less efficient.

If you do not have training with HVAC repair, you will not be able to easily determine if a thermostat is causing the problems you are encountering with your heater. Professionals will need to make the diagnosis so they can provide targeted repairs.
