Southern California is going through a bout of rainy, cold weather. We’re thankful to have the rain since we need it to alleviate the drought. The cold temperatures aren’t as wonderful, but this is why you have a furnace in your home.
But you may have run into a problem with your furnace: it won’t turn on. You can rely on us when you need heater repair in San Fernando Valley, CA. We’ll find out what’s wrong with your furnace that’s keeping it from warming up your house.
On that topic, let’s take a look at some of the reasons you have an obstinate furnace. A few of them are things you can correct on your own without our help.
The furnace switch is off
This is the first thing to look into when your furnace won’t turn on. The furnace switch is a power switch located near the furnace that’s used to shut it off during the summer. You may not have remembered to turn the furnace back on before the cold weather started.
Tripped circuit breaker
We recommend checking on the breaker in the electrical panel for the furnace to see if it’s tripped. (Yes, gas furnaces require electricity to run.) Sometimes an overload from the blower fan motor can trip a breaker and cut off power to the furnace. If the furnace keeps tripping the breaker, call us for assistance: something else is wrong with the furnace.
Furnace overheating
The operation of the furnace’s heating cycle is designed to keep it from getting too hot. In case the furnace does start to overheat, a device called a limit switch will shut down the system. Don’t attempt to keep running a furnace that overheats—you need this problem professionally corrected.
Faulty safety mechanisms
The limit switch is one of several safety mechanisms in a furnace, which also includes a pressure limit switch and a flame sensor. Any of these devices might malfunction and prevent the furnace from turning on, essentially doing their jobs too well.
Failed sequencer
This is a problem specific to electric furnaces. The sequence is responsible for staggering turning on the heating elements to avoid overloading the circuit. A broken sequencer will prevent any electricity from reaching the heating elements.
Gas line problems
If the burners in your gas furnace won’t light, the problem might be in the gas line. A stuck valve can block gas flow, as can build-up in the line. You don’t want to tamper with the gas line for the furnace for safety reasons, so please call our technicians to solve the problem.
Broken thermostat
The thermostat may be what’s stopping your furnace from coming on. Frayed and loose wires can cause the thermostat to lose its connection to the furnace. The thermostat may also become miscalibrated so that it won’t turn the furnace on when it’s supposed to. Our HVAC professionals can repair the thermostat or replace it.
Full breakdown
Finally, your furnace may have failed completely due to age and wear. If you have a furnace that’s more than 15 years old, we strongly recommend you have it replaced when something like this occurs.
