How To Restart A Gas Furnace? Essential Guide

How to Restart a Gas Furnace


To restart your gas furnace with the steps outlined in WikiHow’s guide, you may need to troubleshoot issues related to the pilot light, gas valve, or control unit. In this section, we’ll discuss how to address each of these components in an easy-to-follow format. By doing so, you’ll be able to diagnose and resolve many furnace problems without needing to spend time and money on a professional.

How To Restart A Gas Furnace

The Pilot Light

Understand the pilot light component for a smoother-running gas furnace. It’s a small flame that lights its main burners to provide heat for your home. Don’t forget to regularly clean and inspect these parts.

If the pilot goes out, try cleaning the dirt and debris around it, blowing air in the area, and checking connections are tight. Make sure there is enough gas supply.

Take care of this component to save energy and costly repairs. Shutting off the gas valve is the quickest way to get the heat back on.

The Gas Valve

The gas valve regulates the flow of gas into the furnace. It’s essential for the furnace to work, as it manages the combustion process. A thermocouple or electronic ignition system controls the gas valve, making it open to let the gas in when the thermostat signals.

It’s vital to inspect your gas valve regularly, alongside professional inspections. Check the area around your gas valve for the build-up and consider cleaning it if needed.

My friend had a problem with her furnace not heating even though it was on and functioning properly. An expert figured out that her thermocouple was not working correctly, which meant that the main burner control valve was not opening, disrupting normal operations. She found out that she should have regular inspections of her filament every six months to prevent similar issues.

If you want to find the “boss,” just locate the control unit of your gas furnace – it’s the one responsible for keeping you warm (or cold).

The Control Unit

Gas furnaces rely heavily on the control unit for regulating temperature. It’s like the brain that oversees all its vital functions. Knowing how to manage it is key to optimal performance and safety.

The Control Unit has three important parts: a thermostat, a gas valve, and an igniter.

  • The thermostat measures the temperature and activates the furnace.
  • The gas valve regulates the flow of gas to the burner.
  • Lastly, the igniter sparks and ignites a flame when gas reaches it.

It’s vital to maintain your furnace. Clean or change air filters and check electrical wiring regularly. Calling a qualified technician if you suspect faults is important.

Maintain and observe best practices. This keeps your furnace running well and avoids costly repairs and fire hazards. Get your furnace ready before winter starts! To restart your gas burner, follow these steps:

  1. Set the thermostat to its lowest temperature setting.
  2. Turn off all power to the furnace and wait for 10-15 minutes.
  3. Turn the power back on and set the thermostat to your desired temperature.

Steps for Restarting a Gas Furnace


To restart your gas furnace, you need to follow the steps carefully. In this part, we will discuss the steps you need to take to restart a gas furnace with the sub-sections – checking the thermostat, turning off the breaker panel, checking for a clogged filter, pressing the reset button, and checking for power to the unit. These steps are important to follow to ensure a successful restart of the gas furnace and prevent any damage or problems in the future.

Check the thermostat

To restart your gas furnace, first, check if the thermostat is set on “Heat” or “Auto”. Increase the temperature by 5 degrees and wait a few minutes. If it won’t kick in, you should replace the thermostat’s batteries. That might solve the issue!

Plus, resetting the circuit breaker could help as well. Turn off the breaker, wait for 60 seconds, then turn it back on. This could reset the furnace and help it work properly.

Let’s bid farewell to the furnace’s gas-passing phase! Flip that switch!

Turn off the breaker panel

To restart your gas furnace safely, the breaker panel must be switched off. Doing this correctly is important to prevent any accidents. Here’s a 5-step guide:

Don’t forget that turning off the thermostat isn’t enough. Always turn off the breaker panel first. Label each circuit breaker to make sure you know which is which. This will ensure a safe switch-off. Just be warned: unclog the filter or watch your furnace go up in smoke – either way, it’s a warm welcome to winter!

Check for a clogged filter

When dealing with a gas furnace, remember to check for a clogged filter. It can be easy and have a big influence on the furnace’s performance and air quality in your home. Follow these four steps:

  1. Find the Furnace Filter – Near the blower motor or air handler.
  2. Take out the Filter – Might need unscrewing or unhinging. Read the unit’s manual and safety precautions.
  3. Inspect the Filter – Hold it up to light and look for dirt, dust, or debris. Tap gently on a flat surface and see if dust comes off.
  4. Clean or Replace – If there is too much buildup within 3 months, clean or change the filter before running the furnace again. Ask for professional help if needed.

Other tips for efficiency and security: check carbon monoxide detectors and get annual inspections by certified pros. Each furnace has its own needs for filter cleaning/replacement frequency and timing. Don’t rely only on these steps.

Recently, my neighbors had trouble restarting their gas furnace – even after following the manual. I suggested they get help from an HVAC service provider. The root cause was a severely clogged filtration system. If not detected, it could have been dangerous. Push the reset button and hope for the best – it’s like a game of Russian roulette, but with your furnace.

Press the reset button

Gas furnaces can be a problem – they can unexpectedly stop working, which can be worrisome. To combat this, many furnaces have a reset button. This button serves as a safety measure that helps set the furnace to its original settings, enabling it to work correctly.

Check the manual for the reset button’s location. When you’ve found it, push it down and hold for 10-15 seconds. After, wait a few minutes to see if it starts up.

If your furnace needs frequent reboots or doesn’t start up after pressing the reset button, call an HVAC technician instead of handling it yourself.

Old gas furnaces did not have built-in safety mechanisms – people used to manually relight them using matches or lighters! This was risky and caused fatal accidents. Fortunately, with modern technology and safety regulations, we can reset our furnaces with a simple press of a button, avoiding dangerous risks! Before attempting to wake your furnace, double-check for power.

Check for power to the unit

Confirm whether your gas furnace has a power supply before restarting it. This guarantees the machine works correctly with no electrical malfunctions. Here’s a 5-step guide to check for power:

  1. Look for any visible damage to the power cord.
