Q: We recently moved into our home, and now that it’s gotten colder, we’ve noticed that the furnace won’t turn on. We know we need to run it before the pipes freeze, but we have no idea what the problem is. Can we fix the furnace not turning on instead of calling a technician?

Furnace High Limit Switch Tripping? Here’s What To Do

A: Refrigeration and chattering teeth aside, a faulty home furnace can cause expensive damage – including, as you mentioned, freezing pipes. Cold temperatures or the resulting condensation can potentially damage windows, and it’s possible for a home that isn’t heated during the cold winter months to even suffer structural damage.

Getting your furnace up and running in cold weather is a priority and should be tackled right away, but that doesn’t necessarily mean you need to call a service technician. If your furnace stops working, there are several solutions to furnace problems that you can use, including adjusting the thermostat and, if you have a gas model, resetting the furnace pilot light. Read on for some furnace troubleshooting tactics you can try before calling a repairman.

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 measures the temperature in the room and allows you to set and adjust the desired temperature. The thermostat is usually mounted on one of the main walls in your home, just above the light switch.

Rv Furnace Troubleshooting Tips And System Overview

If your thermostat doesn’t turn on, the device can’t tell the furnace when to turn on. So if you have a programmable thermostat, make sure the display is active, the furnace is on, and the unit is set to heat. If you have a manual thermostat, be aware that during dusting or other household cleaning tasks, the switch may accidentally be turned to the “off” position. Once you find that the thermostat is on, turn the heat up to the temperature that would normally cause the furnace to come on; this temperature may vary from thermostat to thermostat. If the heat does not come on after a minute or so, increase the temperature setting significantly while you continue troubleshooting.

Each gas furnace will have a gas valve or faucet located no more than 6 feet from the unit. Furnace valve designs vary, but often include a small disc with a small handle or lever on it. Some gas valves may look like small boxes, while others may resemble a lever the size of your index finger (often brightly colored).

The valve may have been accidentally closed or someone working on the stove forgot to turn it back on. While valves can vary by manufacturer or manufacturer, a gas valve will usually be in the open position — meaning 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 probably closed. To open it, turn the small handle so that it is parallel to the tube.

If the furnace still does not turn on when the valve is open, check another gas appliance in the home, such as a furnace or fireplace, to see if it is still working. If other gas appliances do not turn on, you may not have gas in your house. This could be due to crews working somewhere on the pipeline, or there could be a gas leak, burst or even a blockage in the pipe. A gas leak can be a dangerous situation, so if you suspect this is the case, call 911 immediately and follow their instructions.

To assess the situation, go outside and check the valve on the street side and then the indoor valve on the side of the house to see if they are on. If they are not on, turning the valve to the open or “on” position (as described above) should allow the gas to re-enter your home. If your furnace and other gas appliances still won’t turn on, contact your utility company to find out if they are working in your area or if there is an outage. If not, check your account balance. Late or incomplete utility payment may result in service interruption, either due to technical failure or human oversight.

Sometimes the reason why the furnace does not turn on is that it is simply turned off. Look for the power switch on the furnace itself, which is probably on a nearby wall or even on the ceiling or floor near the unit. It will often look like a regular light switch and may or may not be labeled. Usually, but not always, the “on” position is higher, although this depends on the installation. Someone unfamiliar with the house can easily accidentally turn off the stove and mistake it for a light switch. Return this switch to the “on” position and wait for the unit to boot. Some furnaces may take several minutes to restart.

Why Your Furnace Blower Motor Won’t Turn On & How To Fix

A clogged air filter will prevent the furnace from heating properly. Over time, the air filter can become clogged with dust, hair or other household debris, making your furnace less efficient. In addition, restricted air flow can cause a constant build-up of heat in the heat exchanger. Each furnace has limit switches that activate when the temperature exceeds a certain point and turn the furnace off. Furnace air filters should be replaced every 1 to 3 months to keep the unit running efficiently, regardless of heating or airflow issues.

To find the filter, look for the place where air flows into the furnace while it is running. Pull out the old filter and look for the model number and size on the side so you know which replacement filter to buy. When replacing the filter, check if there is an arrow on the frame indicating the direction of the air flow. When you slide the new furnace filter into place, make sure the arrow points toward the furnace.

If you’re confident in your DIY skills, you may want to clean the ignition sensor (also known as the flame sensor) on your stove. The ignition sensor is a safety device that detects whether the stove is burning with gas. The sensor uses the temperature increase in the furnace to detect the flame. If the sensor cannot detect a flame, it will shut down the stove to prevent unburned gas from escaping. Accumulation of debris can prevent the flame sensor from working properly. Cleaning can allow the furnace to turn on and function properly. If this troubleshooting tactic seems beyond your DIY skills, it might be time to call in a professional. To understand what it’s all about, follow these basic instructions for cleaning the ignition sensor:
