What to Check First If Your Heater Is not Working?

There is nothing more dangerous than getting home to a cold house when your heater isn’t working. Maintenance of your heater in the fall can help prevent heater failure in the winter.

No matter how hard you try, if your furnace has left you chilly, here are a few things to check before calling a technician that might save you some frustration while getting your furnace running again.

You Must Check The Furnace Power Switch.

On or off switches on some furnaces can be easily accidentally switched off. For example, if you store holiday decorations near your furnace, you may have accidentally turned off the furnace.

Check the switch on the attic of your furnace if your furnace has been worked on by other technicians, like a cable/Internet installer, holiday light setter, electrician, or plumber.

You Should Inspect The Fuse Box For The Heater.

To determine if the problem is related to your heater, check the power supply and your electrical breakers. The heater will sometimes work again after resetting a tripped breaker.

It is knowledgeable to visit an authorized learned if your furnace keeps tripping off, which likely means a safety feature has been engaged. An HVAC technician can determine if the problem is with the heater’s power supply or safety or if it’s a more significant electrical issue that needs an electrician’s care. 

Make Sure The Thermostat’s Batteries are in Good Shape.

Try replacing the batteries if you have an electric thermostat. A simple fix like this often gets a heater working again.

Before the heater turns on, you need to set the thermostat to heat or automatic. For example, if the heat is set to bring the indoor temperature up to 72 degrees and the thermostat is set to “cool,” the furnace will not operate. 

Change The Air Filters.

When was the last time you changed the air filters in your home?

When your home’s air vents become clogged or dirty, the electrical components are worn out. As a result, your system might stop working. Your heater will overheat and shut down if it can’t draw enough air in.

Be Aware of Any Odors.

In the absence of a malfunctioning heater, the air should be odor-free. However, smoky or burnt smells, or the smell of gas, can be worrying signs, and you need to get assistance as soon as you can. 

 You should invest a reproduction monoxide director and fume alarm in their home, so you can detect carbon monoxide leaks on your own if you have any.
