The most common signs of a bad or malfunctioning thermostat are lack of hot or cold air when the device is turned on and an unlit display light. Malfunctioning thermostats occur for a variety of reasons, and in many cases, troubleshooting the issue and following up with a simple fix can alleviate the problem.
A malfunctioning thermostat does not always need to be replaced. Common issues that occur with thermostats include dirt build-up, blown fuses, tripped circuit breakers and loose wiring. Dirt build-up often leads to a mismatched temperature setting which in turn can lead to overheating, over cooling, or a complete lack of hot or cold air.
Blown fuses, loose wiring and tripped circuit breakers are common culprits when the furnace or air conditioning simply does not start, and a maladjusted anticipator is one of the top reasons for a thermostat repeatedly starting and stopping. If troubleshooting and repairing minor issues does not work, replacing the thermostat is the next step. Many households are updating their old thermostats with digital versions. Digital thermostats are very affordable and even offer a variety of convenient features that include digital temperature displays, warning lights and alarms, reminder messages and touch screen capabilities.Learn More
The easiest way to tell if the fireplace flue is open is by placing a hand into a cooled fireplace and feeling for cold air. If there is a burst of cold air, the flue is open. Ceiling-to-floor metal fireplaces have a metal latch located on either side of the fireplace that allows for easy testing of the flue.Full Answer >

The Family Handyman recommends that owners check their thermostat before assuming the problem causing the furnace to blow cold air is something deeper. There are several things to check at the thermostat. The switch needs to be on heat and not cool. If the fan is set to automatic it blows air, regardless of the room temperature. If the thermostat is set too cool, the furnace does not provide heat.Full Answer >
Generally speaking, thermostats work by using a mercury switch that is in contact with a thermometer wire to trigger a temperature-adjustment lever in response to the expansion or contraction of the wires as they are heated or cooled. The expansion and contraction of these wires triggers switch relays that control heating and cooling by triggering either a circulation fan and heater or air conditioner.Full Answer >
