Winterizing your furnace is a top priority and should be addressed immediately, but that doesn’t mean you have to call a maintenance professional. If your furnace stops working, there are several solutions to furnace problems you can take, including adjusting the thermostat and, if you have a gas model, turning on the pilot light on the stove. Read on for some furnace troubleshooting tactics to try before calling a service technician.

The most obvious solution to a furnace that won’t turn on is often overlooked when troubleshooting heating systems: Many people neglect to check the thermostat, the part of your heating system that detects room temperature and allows you to set and adjust the desired temperature. The thermostat is usually installed on one of the main walls of your home, providing nothing more than a light switch.

If your thermostat isn’t on, the device can’t know when to turn on. So, if you have a programmable thermostat, check that the display is on, the furnace is on, and the unit is set to heat. If you have a manual thermostat, note that during dusting or other household cleaning operations, the switch may be accidentally pushed to the “off” position. Once you’ve confirmed that the thermostat is on, reduce the heat to the temperature that normally lights the furnace. This temperature may vary from one thermostat to another If the heat does not come on after about a minute, increase the temperature setting significantly as you continue troubleshooting.

Every gas stove must have a gas valve or spigot within 6 feet of the unit. Furnace valve designs vary, but feature a small disc with a small handle or lever on top. Some gas valves may look like small boxes, while others may resemble levers the size of your index finger (often brightly colored).

The valve may have been closed accidentally or by someone working on the furnace who forgot to turn it back on. Although valves can vary depending on the brand or manufacturer, a gas valve is generally in the open position—which means gas is flowing through the pipe—if the handle on the valve is parallel to the pipe. If the handle is perpendicular to the pipe, the valve is most likely closed. To open it, turn the small handle until it is parallel to the pipe

Why Does My Furnace Make A Weird Smell When I Turn It On?

If the stove still doesn’t explode after opening the valve, check that other gas appliances in the house are working, such as the stove or fireplace. If other gas appliances are not turned on, your home may not have gas. This could be caused by a crew working somewhere on the gas line, or even a gas leak, damage, or blockage in the line. A gas leak can be a dangerous situation, so if you suspect one, call 911 immediately and follow the instructions.

To assess the situation, go outside and check the street side valve and then the house side valve. If it doesn’t turn on, turning the valve to the open or “on” position (as explained above) will allow the gas to flow back into your home. If your furnace and other gas appliances don’t turn on, contact your utility company to see if they work in your area or if there is a service interruption. If not, check your account status Whether due to technical glitches or human error, power outages or incomplete utilities can disrupt payment services.

Sometimes the reason the furnace is on is because it is off. Find the power switch on the furnace itself, perhaps on a nearby wall, or on the ceiling or floor near the unit. This often looks like a regular light switch, and may or may not be labeled. Usually, but not always, the “on” position is turned up, although this depends on the installation. It is easy for someone unfamiliar with the house to accidentally turn off the stove, wrongly mistaking it for a light switch Flip this switch to the “ON” position and wait for the unit to turn on Some ovens may take a few minutes before they start working

Furnace Igniter Heats But No Flame

A clogged air filter will prevent your furnace from heating properly. Over time, the air filter can become clogged with dust, hair, or other household debris, making your furnace less efficient. Additionally, limited air flow can continue to increase heat in the heat exchanger. Every furnace has a limit switch that turns off the furnace when the temperature exceeds a certain point. To keep the unit operating efficiently, the furnace air filter should be replaced every 1 to 3 months, regardless of heating or airflow problems.

To locate the filter, look for the location where air flows into the furnace during operation Slide out the old filter and check the side for the model number and size so you know which replacement filter to purchase. When replacing the filter, check the frame for arrows indicating the direction of air flow. When you slide in the new furnace filter, be sure to position the arrow so that it faces the furnace.

If you are confident in your DIY skills, you may want to clean the ignition sensor (aka flame sensor) on your furnace. The ignition sensor is a safety device that detects whether the furnace gas is burning or not. The sensor uses the temperature rise in the furnace to detect fire. If the sensor does not detect a flame, the stove will be turned off to avoid unburned gas. A buildup of residue can cause the flame sensor to stop working properly Cleaning it can allow the oven to start and function properly If these troubleshooting tactics feel beyond the reach of your DIY skills, it may be time to call a professional To find out what’s involved, consider these basic pointers to clean the ignition sensor:
