What to Do When Your Furnace Just Won’t Stop Running
It can be both irritating and expensive when your furnace keeps running without ever shutting off. Luckily, you might not need to call in the repair people, because there’s a decent chance that the problem is something that you can find and fix easily. Read on to learn how.
It’s best to see if it is the simplest problem before you do anything else. Look at your thermostat. Is it actually at the setting it should be? If it’s set too high, that’s most likely problem right there.
If this doesn’t work, feel the air coming out of the registers. If it is not hot, then the problem is probably a broken blower fan motor. Unfortunately, you’re going to need to call a professional for this one.
If you still haven’t found the problem, then ask yourself when you last changed your furnace’s filter. If it’s been some time or you can’t even remember ever changing it, then go change it now. If the filter is clogged with grease and dust, then it can’t move the hot air through very quickly. This could easily be the cause of the problem, and all you need to do to fix it is change the filter.
If the problem persists, go around your house and check all of the ductwork while the furnace is running. Look for any duct segments that have fallen out of place or come loose. Run your hand around each of the seals to feel if there is any hot air leaking out. Reseal any leaks with HVAC tape, and replace any loose segments.
If nothing else has worked, then your thermostat is probably malfunctioning. Unfortunately, this problem is going to require the professional touch. Even if the thermostat is fine, then there is still most likely some other serious problem. It’s time to bring in the professionals.
Whatever the cause of the problem, it’s best that you act quickly. The longer it goes on, the more money it is wasting.
