One of the simplest reasons why a furnace may not be working is because of a blocked chimney exhaust flue. This happens when debris, such as leaves or birds' nests, accumulates and blocks the airflow. When this happens, the furnace's safety switch shuts down the system to prevent carbon monoxide from entering your home. Luckily, clearing out the chimney exhaust flue is an easy fix that will bring back warmth to your home.

According to Family Handyman, to clear out the chimney exhaust flue, turn off the furnace and climb on top of your roof with a flashlight and a broom. Use the broom to remove any debris blocking the flue's opening, making sure that it's completely clear before turning on your furnace again. By taking these simple steps, you'll ensure that warm air is flowing smoothly through your home without any interruptions caused by a blocked chimney exhaust flue.

Verifying the breaker switch and shut off controls of your furnace is essential to ensure safety. It sounds unbelievable, but sometimes a simple flick of a standard wall switch or resetting a circuit breaker can fix the problem. However, before you do anything, make sure to turn off the power supply to the furnace by locating the main electrical panel and flipping the appropriate circuit breaker. Once that's done, you can remove the front panel covering and locate the blower motor push-in switch. Make sure it's fully depressed before turning on the power supply again.

If your furnace isn't working, one of the potential culprits is a leaky duct. So, how do you detect and avoid them? First, check the room registers to make sure they're open and unobstructed. Then, inspect the ductwork for any visible leaks or damage.

To seal sections of ductwork that may be leaking, use special metal duct tape (don't use regular tape as it won't hold up over time). Pay particular attention to branching points where multiple pieces of duct meet - these are common areas for leaks. Also, make sure all handles protruding from the ducts are tightly secured.

According to Family Handyman, "a typical house loses 20% to 30% of its air through leaks in the ductwork." Avoid this wasteful and costly problem by regularly checking your ducts for leaks and blockages. With proper maintenance and sealing techniques, you can ensure that your furnace is working efficiently and effectively for many winters to come.
