Of course, you’d be alarmed if the furnace in your Murrells Inlet, South Carolina, home failed in the winter. Here are the following five reasons your furnace won’t turn on.

Simple Oversights

Check to see whether you have the switch turned away from heat. Also, check to see if there is enough gas in your furnace’s supply. Simple oversights may make it seem like your system is inoperative.

Thermostat Issues

Whether your thermostat’s wires have loosened or you’re using the wrong type of thermostat for your furnace, there’s a good chance your thermostat could be causing your chilly home. It may be an issue as simple as a battery replacement or as complex as having a broken wire. If the display is blank, simply putting in new batteries could fix the problem.

Worn or Melted Insulation on Wiring

Wiring undergoes wear and tear over time. Worn off or melted insulation on your wiring can cause your furnace to short-circuit. Overloading your electrical system repeatedly could cause the insulation to melt. If you keep blowing fuses and need to constantly reset your circuit breaker, chances are you have a significant internal issue with your furnace. You will need to call in a professional service technician.

Dirty Flame Sensor

If your furnace is in a dusty area of your home, chances are your flame sensor accumulates new dirt on a regular basis. Without regular cleaning, this dirt accumulation will lead to a cold home.

Damage to the Ignitor

Your ignitor lights your gas and is essential to your furnace’s function. Your furnace’s ignitor undergoes stress over time and may eventually show signs of physical damage. Scheduling an inspection and repair of your furnace could reveal that the cause of failure was a cracked ignitor. Your furnace may work again once the ignitor has been replaced.
