Check Your Thermostat to make sure it's ON
When your home isn’t heating properly, the first and easiest place to start is the thermostat. The thermostat measures its surrounding indoor air temperature to control when the furnace turns on or off.
When your thermostat is configured incorrectly, it can lead to your furnace malfunctioning. First, your furnace won’t run if the thermostat isn’t on. If your thermostat approach is to set-it-and-forget-it, simply checking the thermostat batteries, if it’s not a wired unit, may solve the problem. Next, if your thermostat controls your furnace and central air conditioning, it will have a heat and cool setting. Ensure that your thermostat is set to heat.
Another common furnace issue is the improper sizing of your heating system. It seems counterintuitive but furnaces that are too big for their homes create far more energy than is required. This happens frequently, resulting in the thermostat turning off the furnace before it has had a chance to complete a full heating cycle. Furnaces of all sizes are intended to operate in cycles, with each producing a set quantity of output over a set length of time. If your furnace cannot complete a full heating cycle it will not heat your home efficiently, cycling on and off frequently.
The first thing you want to check is the air filter. Over time, furnace filters get dirty. Dirt and dust can quickly clog the filter, which impedes airflow, worsens indoor air quality, and can even prevent the furnace from turning on in some cases. It can also become a fire hazard and cause premature breakdowns due to excessive dust and dirt. Turn your thermostat off and flip the furnace switch off before you conduct any work on the furnace. Check your air filter every 30 days (set calendar reminders). Hold your filter up to a light source — if light cannot pass through easily, it should be cleaned or replaced.

Check the thermostat setting to be sure it is correctly set for “heat” or the fan is set to “on” or “auto”. If the thermostat settings are correct, a furnace that turns on and off constantly can be caused by a system that is not properly sized for the home, a thermostat that is placed too close to a heating source, or a faulty thermostat. These issues may need to be resolved by a professional service technician. Before making that call, be sure to try steps 2 and 3 as described below. Check the air filter.

The high limit switch has a flame sensor rod positioned on its surface. The minute your furnace starts, it is the flame sensor’s job to inspect the presence of a flame. If no pilot flame is detected, the sensor will trigger safety features to shut down the system. When the flame sensor malfunctions, the furnace stops running a cycle. The problem usually lies in the maintenance of the sensor. Over time, soot, debris, and other byproducts accumulate over the sensor rod. This hampers its working, causing delays in sensing the flame and abruptly shutting the system. If the damage is not far-fetched, you can clean the flame sensor by unscrewing it from the access panel.
The furnace switch provides power to the system when it is flipped up in the "on" position. It looks like a light switch and should be on the side of your furnace or nearby on the wall. If you have no warm indoor air, check the furnace unit and find the switch. If it is flipped down, it is off and not providing power to the unit. Make sure to flip it back on, and hopefully, your furnace will resume its heating. Additionally, you may be wondering why the switch got shut off in the first place. Well, since it looks like a light switch, it can easily be mistaken for one.
Check the thermostat. Anytime you have furnace problems, your first step should be to check the thermostat.
