Why Is My Furnace Not Coming On

Jan 24, 2020

Furnaces are wonderful! Year after year, they’ve helped us to keep warm throughout even the coldest of winter nights without a hitch. However, it is when they quit working that serious problems happen. Frequently, furnaces will not turn on because they have not been utilized for a long period of time. Nevertheless, this isn’t the case all the time. Here we discuss some top reasons for your furnace not turning on. 


Why Your Furnace Might Not Be Firing Up

Have A Look At Your Thermostat 

Here is one of the prime reasons why furnaces quit working. If you think of it, it is like having a TV with no remote. Futile right? To start off with, be sure your thermostat is set to the “heating” setting. If you have it set to “fan,” you won’t be feeling any heat coming out of your vents. Next, you should consider whether it’s faulty wiring. If it is, we urge you to talk to a professional before going any further. Finally, if you’ve covered those bases, you should consider whether your thermostat is too old, and it’s time for a new one to be installed. If this is the case, it’s time to call a professional. A pro can install a thermostat and explain to you how it works. Here at Grove City Heating & Air, we would love to install a pre-bought thermostat for you at an economical price! 


Is Your Breaker Tripped?

If a circuit breaker trips, it’s your system’s way of telling you that you have too much electricity going through a certain part. Because it is not able to handle all the electricity moving through it, it cuts off so that your unit does not overheat or cause further damage. Circuit breakers are intended to trip, to help stop the wires from overheating and causing a fire. It would be best if you always allowed a professional to take care of a bad circuit breaker. When it is not installed correctly, there can be serious problems. 


When The Pilot Light Goes Out

If you want to see if the pilot light is a problem you can solve on your own, have a look under your furnace to find out if the blue pilot light is still lit up. If the light is out, you might be able to light it back up again with a lighter. But if you can’t light it, you should definitely call a professional. If a new pilot light needs to be installed, they aren’t expensive to repair.


How Much Power Is Getting To The Unit?

When your furnace is not receiving adequate power to operate it correctly, several different wiring problems could be the reason. In this case, we firmly suggest you not to touch the unit and call a professional. Any out of place wires are able to mess up a system and threaten your furnace’s lifespan. 


Inadequate Gas Supply

Setting your gas to being on only partially is worse for your furnace than leaving it fully turned on. A lot of homeowners presume that putting it on only half of the way helps to not let as much into the system. While this is true, it is still bad for the life of your furnace. Leaving it on partially can reduce your system’s lifespan and can be a serious safety hazard. We strongly advise, either turn it all the way on or all the way off.


Condensation Issues

A furnace’s condensation pan gathers excess water when the reservoir is full. If the pan fills up, it will shut your system totally off. The water then drains out. After this happens, a furnace won’t try to restart again for safety reasons. Seek professional support if you don’t know where the pan is at or if it keeps filling up at an alarming rate.
