Few things concern a homeowner more than when their furnace begins to show signs of a problem. If your furnace is gas-powered, maintaining the system in prime operating shape is essential for the safety of your home’s inhabitants. One indication that your furnace might require some consideration is when it won’t shut off and runs nonstop, even if the temperature reaches the temp set on the thermostat. To educate our readers about this issue, we at Grove City Heating & Air composed the following.
Probable Causes For a Furnace That Runs Constantly
Start by checking the air that your furnace is blowing out of your vents. See if it feels warm or cool. If your system is continually running, but only cool air is being sent out, you could have an issue with your blower motor. In some cases an electrical problem, like corroded wires, can make your blower work continuously. If you find this is what’s creating your problem, we strongly urge that you don’t venture to work on the furnace by yourself. This is not a DIY project. It’s best to consider safety and efficiency first by giving a trusted HVAC pro a call to manage any servicing.
Clogged Up Air Filters
If the air emerging from your vents is warm, but the flow of the air is weak, this could be a sign that your filters could have become dirty and probably have become plugged up with dust and particles. Blocked up air filters prevent the air that your furnace requires to operate from getting there, which causes your whole system to have to labor needlessly to reach the same wanted temperature in your home. This issue is an easy one to resolve, however. Replace your air filters with new ones, and if the problem goes away, you’ve solved it. If it doesn’t, give us a call.
Check your thermostat and be sure that it has been set to the temperature you desire and that it has been set on the “auto” setting instead of the “on” setting. The “on” setting makes your furnace run constantly. “Auto” makes your system run until it reaches the desired temperature. It then switches off automatically when it hits that specific temperature, except when the temperature falls below that level again. However, if your thermostat’s settings appear accurate, and the furnace still continues running round-the-clock, there’s a possibility you could have a faulty thermostat. If you surmise this is the problem, reach out to an HVAC specialist to inspect, calibrate, or possibly even replace it.
Pilot Light Difficulties
A lot of more out-of-date furnace models have a pilot light that’s intended to remain lit completely throughout the winter. However, if this happens to go out, it could make your furnace run nonstop, and blow only cool air always. If you notice this is the issue, you could relight your pilot using the manufacturer’s instructions for your model. Nonetheless, the majority of furnaces these days are furnished with electric start pilots that automatically light when it demands heat. It’s plausible that someplace inside that machine, there is a flaw that won’t let the pilot light stay lit. If this is the problem, an HVAC pro can correct this.
