Heating breakdowns always seem to happen when you least expect them, and with winter officially here in Los Angeles, CA, you can’t afford to wait around for a repair service. But just because your heating system won’t turn on, that doesn’t mean that the problem requires a professional technician. While laymen should never attempt to repair a faulty furnace themselves, you can always check your system for basic fixes that require no training to resolve. They could help you avoid a service charge from bringing a technician to your home for no reason.
Is the Thermostat Set Properly?
Thermostats almost never require repairs, but some of them run on battery power, and if the battery wears out, the heater may not turn on. In addition, another family member may have altered the settings, or someone might have accidentally brushed against the controls. The thermostat should be your first stop when checking for problems.
Are a Large Number of Vents Closed?
Generally speaking, you should never close more than one or two vents in your home at any given time. Closing more than 20% of your vents will keep the heat out of unwanted parts of the home, but it could also cause the hot air to back up into the body of your furnace. Most systems will shut down automatically rather than risk important components overheating. Opening the vents may alleviate the problem.
Is the Breaker Switch Set?
An external power surge could trigger the breaker giving power to the heater (and almost all heaters use at least a little electrical power, even those that run on gas or other types of fuel). Check the breaker box and reset the switch, then run the heater for a bit. If the problem doesn’t repeat itself, it should be good to go.
