Top 4 Reasons Your Furnace Won’t Turn On

Few things in life are as frustrating as discovering that your heating system refuses to turn on or work properly right when you need it the most. The good news is, most furnace-related problems can be fixed with the right knowledge and equipment, so don’t start googling “furnace replacement near me in Cherry Hill” just yet. 

We previously wrote about the most frequently encountered furnace problems and explained why using an old furnace can be dangerous. Now we’ll give you some pointers on how to deal with a HVAC system that switches off as soon as you turn it on or even appears completely dead. Read on to learn more. 

How do you restart a furnace?

The answer to this question depends on what exactly has caused your furnace to shut down. Keep in mind that, unless the cause of the problem is something mundane (eg., someone has unplugged the furnace power cord or turned the emergency switch off), it’s highly advised that you leave any repairs to a reputable HVAC service. 

Here are 4 common reasons why your furnace has shut down:

1. The gas valve has been shut

If gas isn’t getting to the HVAC system like it should, there’s a possibility you may have a gas leak on your hands. If you smell gas, evacuate your house immediately, move to a safe distance, and alert your fire department and your gas company ASAP. 

2. The furnace clicks on but doesn’t fire up

This can be caused by a dirty sensor or ignitor, and is often the result of irregular or improper HVAC maintenance. Having your heating system serviced annually by a professional HVAC technician will prevent this problem from occurring in the future.

3. The filter is clogged

Furnaces contain one or more filters that have to be changed regularly in order to prevent them from getting dirty. If your filters have been changed recently (or washed, if they’re reusable), and the airflow is still obstructed, you should reach out to a HVAC company and have them check your ducts.

4. No power

Someone may have accidentally cut the power supply to the furnace. Another possibility is that the circuit breaker that powers your furnace has popped. A faulty wireless thermostat may also be the problem, so make sure to test it by increasing the temperature by 5 degrees or so.

Where is the reset button on my furnace

The purpose of a furnace reset button is to turn the furnace off before it can trip your circuit breaker. This is typically done if the temperatures inside the furnace get too high, or if the electrical system is interrupted in some way. 

In most furnaces, the reset button is located in the blower compartment on the side of the blower motor. This button is usually painted yellow or red (or some other color that is designed to stand out). 

If the reset button has popped up, simply press it back down again and see if that helps. In some models, you may have to hold it down for 30 seconds or so before it will actually do its thing. The housing may be hot, so make sure to wear thick gloves to keep from burning yourself.
