In a lot of instances, a furnace problem is relatively easy to fix. A trained technician can correct the problem quickly, or a homeowner might be able to do some troubleshooting on their own. Understanding what some of the most common furnace problems in cold weather are can help you know what to look for and what to do to fix up . Whether you’re a first-time homeowner or you’re running a business at a brick-and-mortar store, you’re likely to run into at least a few problems with your furnace over the years.
Why Does the Furnace Click But Not Turn On?
The furnace may have an insufficient power supply which means it not receiving enough voltage from the circuit breaker. It could also be faulty thermostat settings. To resolve these issues, try resetting the furnace by turning off the circuit breaker for 20 minutes then turning it back on again. It could also be an electronic ignition problem. When the thermostat calls for heat. A gas furnace opens the gas valve, and once the sensor recognizes there is gas flowing it will ignite it which can have a clicking noise (like a gas stove).
Common Furnace Problems
The Thermostat Isn’t Set to Heat
We don’t mean to the HVAC equivalent of the stereotypical IT “help” desk, but we have to at least ask: Is your thermostat actually on—and on the right setting? Even if you’re certain it is, go check. It’s possible someone accidentally switched it off or made an overly aggressive temperature adjustment. It’s also possible that your thermostat batteries died. We’ll keep our fingers crossed for you while you check.
Keeps Turning on and Off
As a furnace heats your home, it typically cycles on and off, trying to maintain the temperature set on the thermostat. Depending on the programmed temperature and the outdoor temperature. Heat the room or home to the desired temperature, then cycle off again several times an hour. If a furnace starts short cycling or turning on and off frequently, without ever reaching the set temperature, that is usually a sign that something is wrong. During a short cycle, it will only run for a couple of minutes before it turns off again. Often, the cause of a short cycle is a lack of airflow in the furnace, which causes it to overheat.
Dirty and Clogged Filters
A dirty or clogged filter can reduce the intake your furnace needs to function, reducing its efficiency. It could also potentially lead to the damage of your limit switch. Ensure your filters are swapped out once a quarter to ensure peak performance
